Description
SUNSCREEN COMPOSITIONS
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to sunscreen compositions. More particularly, the present invention relates to sunscreen compositions that have enhanced sensory properties when applied.
II. Description of the Prior Art Sunscreen compositions are applied to the skin to protect the skin from the sun's ultraviolet rays that can lead to erythema, a reddening of the skin also known as sunburn. Sunlight or ultraviolet radiation in the UV-B
range has a wavelength of 290nm to 320nm and is known to be the primary cause of sunburn. Ultraviolet rays at a wavelength of 320nm to 400nm, known as UV-A radiation, produces tanning of the skin. However, in the process of doing so, the UV-A rays can damage or harm the skin.
Besides the immediate malady of sunburn, excessive sunlight exposure can lead to skin disorders. For instance, prolonged and constant exposure to the sun may lead to actinic keratoses and carcinomas.
Another long-term effect is premature aging of the skin. This condition is characterized by skin that is wrinkled, cracked and has lost its elasticity.
As stated above, sunscreens are typically formulated with the goal of inhibiting skin damage from the sun's rays. The sunscreen composition filters or blocks the harmful UV-A and UV-B rays that can damage and harm the skin. It is believed that sunscreen agents accomplish this by absorbing the UV-A and/or UV-B rays.
In general, sunscreen compositions are oil-in-water emulsions. In this system, the UV-absorbing compounds are typically incorporated into the oil phase.
Consumers consider many factors when purchasing a sunscreen product, such as, the sun protection factor (SPF), how durable the product is after applying it over the skin, the shelf life of the product, and product form (i.e., lotions, gels, creams, and sprays). Another important and influential property of a sunscreen product considered by a consumer is how the product feels and how well it spreads over the skin. Typically, consumers want a sunscreen that feels soft and silky and can be applied in a smooth, continuous film over the skin. Ultimately, product feel could determine whether the consumer decides to purchase the product.
The sunscreen compositions of the present invention provide the user with an enhanced soft, silky feel when applied to skin while still providing superior protection from damaging ultraviolet light.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a sunscreen composition that can be effectively applied as a lotion.
It is another object of the present invention to provide such a sunscreen composition that has an enhanced soft, silky feel when applied to the skin.
It is still another object of the present invention to provide such a sunscreen composition that spreads uniformly over the skin.
It is yet another object of the present invention to provide such a sunscreen composition that is a stable oil-in-water emulsion.
To accomplish the foregoing objects and advantages, the present invention, in brief summary, is a sunscreen composition that has at least one sunscreen agent, at least one glucoside emulsifier, and water.
Preferably, the sunscreen composition also contains at least one of the following additional components: an emulsifier other than glucoside, emollient, skin-feel additive, moisturizing agent, film former/waterproofing agent, pH adjuster/chelating agent, preservative, or any combinations thereof.
DETAILED DESCRIPTION OF THE INVENTION
The present invention is a sunscreen composition that is provided as a stable oil-in-water emulsion. The composition includes at least one sunscreen agent and at least one glucoside emulsifier. The composition also has water. Preferably, the sunscreen composition also has one or more of the following additional components: an emulsifier other than glucoside, emollient, skin-feel additive, moisturizing agent, film former/waterproofing agent, pH adjuster/chelating agent, preservative, or any combinations thereof.
The sunscreen composition of the present invention is uniquely formulated to provide an enhanced feeling of softness and silkiness when the sunscreen composition is applied to the skin. Moreover, the composition is capable of being easily and uniformly applied over the skin.
These enhanced properties are achieved, in large part, by formulating the sunscreen composition as a stable oil-in-water emulsion, where the oil phase has an amount of glucoside emulsifier such that the unexpected soft, silky properties are realized when the sunscreen is applied to the skin.
The one or more sunscreen agents that can be used in the present invention must be capable of absorbing or blocking the harmful effects of ultraviolet radiation. In addition, they must be non-toxic and non-irritating when applied to the skin. Suitable sunscreen agents that may be used in the sunscreen composition include, for example, para-aminobenzoic acid (PABA), butyl methoxydibenzoylmethane (avobenzone), benzophenone-1, benzophenone-2, benzophenone-3, benzophenone-4, benzophenone-6, benzophenone-8, benzophenone-12, methoxycinnamate, ethyl dihydroxypropyl-PABA, glyceryl PABA, homosalate, methyl anthranilate, octocrylene, octyl dimethyl PABA, octyl methoxycinnamate, octyl salicylate, PABA, 2-phenylbenzimidazole-5-sulphonic acid, triethanolamine salicylate, 3-(4-methylbenzylidene)-camphor, red petrolatum, zinc oxide, titanium dioxide, 3-(4-methylbenzyldine)boran-2-one(methylbenzindinecamphor), benzotriazole, phenylbenzimidazole-5-sulfonic acid, methylene bis-benzotrizolyl tetramethylbutyl phenol, or any mixtures thereof.
The preferred sunscreen agents are avobenzone, benzophenone-3, octyl methoxycinnamate, octyl salicylate, homosalate, zinc oxide, or any mixtures thereof.
The one or more sunscreen agents are included in a present composition at about 1 weight percent (wt.%) to about 40 wt.% of the total weight of the composition. The amount of sunscreen agent in the composition will vary in the above range depending on the sun protection factor (SPF) desired. The higher the SPF, the greater the total amount of sunscreen agent. Preferably, the one or more sunscreen agents are included at about 4 wt.% to about 35 wt.% to achieve a SPF of about 2 to about 50.
As noted above, it has been discovered that the inclusion of one or more glucoside emulsifiers in the sunscreen compositions of the present invention results in compositions that have an enhanced soft, silky feel when applied to the skin. Preferably, the one or more glucoside emulsifiers are selected from the group consisting of: cetearyl glucoside, cocoyl glucoside, cocoyl ethyl glucoside, disodium coco-glucoside citrate, disodium coco-glucoside sulfosuccinate, lauroyl ethyl glucoside, myristoyl ethyl glucoside, octyl dimethicone ethoxy glucoside, oleoyl ethyl glucoside, sodium coco-glucoside tartrate, or any mixtures thereof. Most preferably, the glucoside emulsifier is cocoyl glucoside mixed with cetearyl alcohol.
This mixture is sold under the tradename MONTONOV 82 by SEPPIC. It has been unexpectedly found that the inclusion of MONTONOV 82 imparts an exceptional and enhanced soft, silky feel to a user's skin when a sunscreen composition of the present invention is applied.
The amount of glucoside emulsifier present in a sunscreen composition of the present invention is about 1 wt.% to about 10 wt.% of the total weight of the composition. Preferably, the glucoside emulsifier is present in an amount about 2.5 wt.% to about 7.5 wt.% of the total weight of the composition.
The compositions of the present invention also include water. Water is present in an amount about 45 wt.% to about 75 wt.%, and preferably about 50 wt.% to about 65 wt.%, of the total weight of the sunscreen composition.
In addition to the one or more glucoside emulsifiers, one or more additional emulsifiers may also be included in the sunscreen compositions of the present invention. The one or more additional emulsifiers, in conjunction with the one or more glucoside emulsifiers, enable two or more immiscible liquids to be combined homogeneously, while increasing the viscosity of the composition. Moreover, the emulsifiers act to stabilize the composition.

This mixture is sold under the tradename MONTONOV 82 by SEPPIC. It has been unexpectedly found that the inclusion of MONTONOV 82 imparts an exceptional and enhanced soft, silky feel to a user's skin when a sunscreen composition of the present invention is applied.
The amount of glucoside emulsifier present in a sunscreen composition of the present invention is about 1 wt.% to about 10 wt.% of the total weight of the composition. Preferably, the glucoside emulsifier is present in an amount about 2.5 wt.% to about 7.5 wt.% of the total weight of the composition.
The compositions of the present invention also include water. Water is present in an amount about 45 wt.% to about 75 wt.%, and preferably about 50 wt.% to about 65 wt.%, of the total weight of the sunscreen composition.
In addition to the one or more glucoside emulsifiers, one or more additional emulsifiers may also be included in the sunscreen compositions of the present invention. The one or more additional emulsifiers, in conjunction with the one or more glucoside emulsifiers, enable two or more immiscible liquids to be combined homogeneously, while increasing the viscosity of the composition. Moreover, the emulsifiers act to stabilize the composition.
One or more additional emulsifiers that can be used in the present invention include, for example, butylated PVP, cetyl alcohol, sodium acrylate/sodium acryloyld i methyltau rate copolymer, diethylhexyl napthalate, sorbitan oleate, sorbitan sesquioleate, sorbitan isostearate, sorbitan trioleate, polyglyceryl-3-diisostearate, polyglycerol esters of oleic/isostearic acid, polyglyceryl-6 hexaricinolate, polyglyceryl-4-oleate, polygylceryl-4 oleate/PEG-8 propylene glycol cocoate, oleamide DEA, sodium glyceryl oleate phosphate, hydrogenated vegetable glycerides phosphate, or any mixtures thereof.
The preferred additional emulsifiers are butylated PVP, cetyl alcohol, sodium acrylate/sodium acryloyldimethyltaurate copolymer, diethylhexyl napthalate, or any mixtures thereof.
The amount of additional emulsifier present in a sunscreen composition of the present invention is about 0.01 wt.% to about 5 wt.% of the total weight of the composition. Preferably, one or more emulsifiers in an amount about 0.05 wt.% to about 2 wt.% of the total weight of the composition are used.
The present composition may include one or more emollients. An emollient provides a softening or soothing effect on the skin surface and is generally considered safe for topical use. It also helps control the rate of evaporation and the tackiness of the sunscreen composition.
Suitable emollients include, for example, cyclomethicone, dimethicone, dicapryl maleate, caprylic/capric triglyceride, mineral oil, lanolin oil, coconut oil, cocoa butter, olive oil, aloe extracts such as aloe vera, jojoba oil, castor oil, fatty acid such as oleic and stearic, fatty alcohol such as cetyl and hexadecyl (ENJAY), diisopropyl adipate, hydroxybenzoate esters, benzoic acid esters of C9-C15 alcohols, isononyl iso-nonanoate, alkanes such as mineral oil, silicone such as dimethyl polysiloxane, ether such as polyoxypropylene butyl ether and polyoxypropylene cetyl ether, C12-C15 alkyl benzoate, or any mixtures thereof.
The preferred emollients are cyclomethicone, dimethicone, dicapryl maleate, caprylic/capric triglyceride, aloe vera, or any mixtures thereof.
The total amount of emollient present in the sunscreen composition is typically about 0.10 wt.% to about 30 wt.% of the total weight of the composition. The preferred amount of emollient is about 1 wt.% to about 20 wt.%.
As stated above, the feel of the sunscreen composition upon application to the skin may be the ultimate consideration of a consumer when purchasing a sunscreen. Moreover, a smooth, silky sunscreen composition may be more uniformly applied over the skin. To further enhance the feel of the sunscreen compositions of the present invention when applied to the skin, a skin-feel additive may be included. Suitable skin-feel additives include, for example, synthetic polymers, silicones, esters, particulates, or any mixtures thereof. Preferably, the skin-feel additive is a synthetic polymer, nylon-12. Nylon-12 includes microscopic nylon beads, which act like ball bearings on the skin. Therefore, when the composition is applied to the skin, an enhanced silky, smooth feeling results and the composition can be applied evenly over the skin. Also, the nylon-12 has unexpectedly been found to absorb the oil in the sunscreens upon application. Thus, the nylon-12 adds slip to the composition without imparting an undesirable greasy feel.
Preferably, the skin-feel additive is present in a present sunscreen composition in an amount about 0.10 wt.% to about 5 wt.% of the total weight of the composition. More preferably, it is present in an amount about 0.30 wt.% to about 0.70 wt.% of the total weight of the composition.
The pH of the compositions of the present invention may be adjusted by one or more basic pH adjusters and/or chelating agents. For example, sodium hydroxide, triethanolamine, trisodium ethylenediaminetetraacetic acid, or any mixtures thereof are suitable pH
adjusters/chelating agents that may be included in the sunscreen compositions of the present invention.
An effective amount of a pH adjuster and/or chelating agent that may be included to adjust the pH of the final composition to about 3 to about 9. Preferably, the pH is adjusted to about 6 to about 8.
The preferred additional emulsifiers are butylated PVP, cetyl alcohol, sodium acrylate/sodium acryloyldimethyltaurate copolymer, diethylhexyl napthalate, or any mixtures thereof.
The amount of additional emulsifier present in a sunscreen composition of the present invention is about 0.01 wt.% to about 5 wt.% of the total weight of the composition. Preferably, one or more emulsifiers in an amount about 0.05 wt.% to about 2 wt.% of the total weight of the composition are used.
The present composition may include one or more emollients. An emollient provides a softening or soothing effect on the skin surface and is generally considered safe for topical use. It also helps control the rate of evaporation and the tackiness of the sunscreen composition.
Suitable emollients include, for example, cyclomethicone, dimethicone, dicapryl maleate, caprylic/capric triglyceride, mineral oil, lanolin oil, coconut oil, cocoa butter, olive oil, aloe extracts such as aloe vera, jojoba oil, castor oil, fatty acid such as oleic and stearic, fatty alcohol such as cetyl and hexadecyl (ENJAY), diisopropyl adipate, hydroxybenzoate esters, benzoic acid esters of C9-C15 alcohols, isononyl iso-nonanoate, alkanes such as mineral oil, silicone such as dimethyl polysiloxane, ether such as polyoxypropylene butyl ether and polyoxypropylene cetyl ether, C12-C15 alkyl benzoate, or any mixtures thereof.
The preferred emollients are cyclomethicone, dimethicone, dicapryl maleate, caprylic/capric triglyceride, aloe vera, or any mixtures thereof.
The total amount of emollient present in the sunscreen composition is typically about 0.10 wt.% to about 30 wt.% of the total weight of the composition. The preferred amount of emollient is about 1 wt.% to about 20 wt.%.
As stated above, the feel of the sunscreen composition upon application to the skin may be the ultimate consideration of a consumer when purchasing a sunscreen.

Also, the nylon-12 has unexpectedly been found to absorb the oil in the sunscreens upon application. Thus, the nylon-12 adds slip to the composition without imparting an undesirable greasy feel.
Preferably, the skin-feel additive is present in a present sunscreen composition in an amount about 0.10 wt.% to about 5 wt.% of the total weight of the composition. More preferably, it is present in an amount about 0.30 wt.% to about 0.70 wt.% of the total weight of the composition.
The pH of the compositions of the present invention may be adjusted by one or more basic pH adjusters and/or chelating agents. For example, sodium hydroxide, triethanolamine, trisodium ethylenediaminetetraacetic acid, or any mixtures thereof are suitable pH
adjusters/chelating agents that may be included in the sunscreen compositions of the present invention.
An effective amount of a pH adjuster and/or chelating agent that may be included to adjust the pH of the final composition to about 3 to about 9. Preferably, the pH is adjusted to about 6 to about 8.
A moisturizing agent, such as a humectant, may be used in the compositions of the present invention. Suitable humectants include, but are not limited to, glycerin, polyethylene glycol, polypropylene glycol, sorbitol, PEG-4, or any mixtures thereof.
One or more moisturizing agents are optionally included in the compositions of the present invention in an amount about 0.1 wt.% to about 1 wt.% of the total weight of the composition. Preferably, about 0.25 wt.%
to about 0.75 wt.% of one or more moisturizing agents may be used in the composition.
Another component that may be used in a sunscreen composition of the present invention is a film former/waterproofing agent. The film former/waterproofing agent is a hydrophobic material that imparts film forming and waterproofing characteristics to the emulsion. One such agent is polyethylene, which is available from New Phase Technologies as PERFORMALENE 400, a polyethylene having a molecular weight of 400.
Another suitable water-proofing agent is polyethylene 2000 (molecular weight of 2000), which is available from New Phase Technologies as PERFORMALENE 2000. Yet, another suitable film former/waterproofing agent is synthetic wax, also available from New Phase Technologies as PERFORMA V-825. One or more film formers/waterproofing agents may be present in a composition of the present invention in an amount about 0.1 wt.% to about 5 wt.% of the total weight of the composition.
Optionally, one or more preservatives may be included in a composition of the present invention. The preservative protects the composition from microbial contamination and/or oxidation. As such, the preservative can include an antioxidant. Preservatives, such as diazolidinyl urea, iodopropynyl butylcarbamate, chloromethylisotiazolinone, methylisothiazolinone, vitamin E and its derivatives including vitamin E
acetate, vitamin C, butylated hydroxytoluene, methylparaben, or any mixtures thereof, may be included as a preservative in a composition of the present invention.
