This invention is concerned with improvements in or relating to hair sprays.
It has been proposed to use water-soluble synthetic resins, e.g. half esters of copolymers of maleic anhydride, condensation products of formaldehyde with hydantoin substituted in the -position, N-vinyl-Z-oxazolidone polymcrs, polymers of N-vinylpyrrolidone or its copolymers with vinyl acetate, polyvinylimidazole and panthenol in aerosol hair sprays.
These water-soluble synthetic resins effect a sufi'icient still'ening of the hair and impart gloss to it. They have however the important disadvantage that in the case of slightly greasy hair this looks unsightly and forms locks and when used in conjunction with water waves (waves prepared with the aid of water) these sag if the air i too humid.
It has been proposed to use water-insoluble resins, namely those which have been obtained by esterificatien of phthalic anhydride with pentacrythritol in aerosol hair sprays. These resins are however neither soluble in nor compatible with fats, so that that in most cases they are not able to absorb the grease produced by the scalp and the gloss of the hair is lost because the surface of the hair becomes uneven.
We have now surprisingly found that certain polyester resins do not have these disadvantages and may be used to yield hair sprays which absorb grease excellently. Since they also forman even surface on the single hairs, even with very greasy hair, they impart a very good gloss to the treated hair. Due to their good fat solubility and fat compatibility it is also possible to use fatty substances in the hair sprays and thus produce very suitable hair sprays for dry hair. Moreover, the resins are odorless, clear and physiologically inert.
According to the invention there is provided a composition suitable for use as a hair spray comprising a synthetic resin of a melting point about 40 C. functioning as a hair setting compound, said synthetic resin being an esterification product of a phthalic acid (or an anhydride where such exists) and a dihydric alcohol, and a propellant and/or a perfume. The said dihydric alcohol is an alkane diol of 2 to 6 carbon atoms, an ether of a polyhydrie alcohol having 3 to 6 hydroxy groups, in which the hydroxy groups in excess of two are ctherified by alkyl groups of l to 3 carbon atoms, 4,4-clihydroxydicyclohexylpropane or a mixture of any one of the aforementioned alcohol components with less than an equivalent amount with respect to the latter of a polyhydric alcohol containing at least 3 and at most 6 hydroxy groups.
The propellant is preferably a fiuorohydrocarbon or a chlorofiuorohydrocarbon in which even all of the hydrogen atoms may be substituted by halogen atoms, particularly the variou chlorofiuoromethanes. As propellant there is also suitable octafluorocyclobutane, if desired in admixture with isobutane, the proportion of which in the mixture may be between and 33%.
The synthetic resin may be produced by reaction of the above-mentioned acids with the above-mentioned dihydric alcohols, for example in an equivalent ratio from 1:09 to 1:1.4, preferably from 1:1 to 1:1.25. In general the esterification is preferably carried out until the resin has an acid value from so to 150, mtvtu'itageously from 90 to 120. Such resins should be hard and non-tacky; thus they should have a melting point above 40 C., preferably above C. In general they are distinguished by a good solubility in halogen-containing, especially chlorine-containing hydrocarbons, such as methylene chloride, and generally also in lower and higherhlcohols.
The dihydric alcohol component of the resin preferably contains at least three carbon atoms bound to each other by carbon to carbon bonds. The alcohol component may be, for example, ethylene glycol, propanodiol-l,2 or -l,3, butanediol-l,3 or butancdiol-1,4, hexanediol-2,5, hcxcnediol-1,6 or a mixture of such alcohols, but preferably it is 2,2-dimethyl propanediol-1,3 or 4,4-dihydroxy-dicyclohexylpropane. Homologues of this last-mentioned substance may also be used. As aleohol component there may also be used ethers of polyhydric alcohols in which the hydroxy groups in excess of 2 are etherified by shortchaincd aliphatic radicals such as methyl, ethyl, propyl or isopropyl but which others still contain 2 free hydroxy groups. According to a further preferred embodiment the synthetic resins may be modified inasmuch as the alcohol component used is a mixture of a dihydric alcohol with less than an equivalent portion with respect to the latter of a polyhydric alcohol containing at least 3 hydroxyl groups e.g. glycerol, trimethylolethane, trimethylolpropane, pentaerythritol, sorbitol or mannitol. The polyhydric alcohol may be used in such modified polyester resins, for example in an amount up to 80 equivalent percent, preferably between and equivalent percent, calculated on the dihydric alcohol.
In addition to the synthetic resin the hair sprays according to the invention may also contain additives such as solvents and diluents.
Of course, in all instances mixtures of several compounds may be used instead of a single compound.
In order that the invention may be well understood the following examples are given by way of illustration only. In the examples parts are by weight unless otherwise stated.
Example 1 (a) A fat-free hair spray can be obtained by mixing the following raw materials to form a base:
