The binding agent that the detailed Description Of The Invention localized immobilization is used
Topical adhesive of the present invention is directly used on the skin.In specific application, binding agent can be used as function carrier (distribution chemical compound) and be used for fixing, and in other is used, needs to improve fixing and the anti-function of wiping.Topical adhesive of the present invention is used for functional articles, as beauty treatment thing or drug conveying articles for use such as skin treating material, cream, skin lotion, hormone, vitamin, deodorizer or the medicine that a kind of material is provided to skin; Improve looks on the other hand thing or drug conveying articles for use also can provide a kind of material that distributes from skin, as insecticide, suck medicine or spice; In addition, binding agent of the present invention also can be used for not being fixed to the functional articles on the skin, but as parts in the articles for use, these articles for use need have the long time of staying such as ornamental cosmetics (lip pomade, eye shadow, stage foundation cream) or cleaning supplies (hand cleaner, facial film, be used in particular for the sanitary cleaning agent of pore) on skin.The term that the present invention uses " skin " relates to human or animal's skin appearance face really.
For articles for use of the present invention are fixed on the skin, in some applications, also be necessary usually in the topical adhesive that on the specific region on the skin side, provides of articles for use, in other was used, local viscose binder was a kind of chemical compound of articles for use component.The physics of topical adhesive, rheology and adhesive property
Even resembling, topical adhesive is used on human or animal's the skin the contact adhesive, be understood that, have only according to the distinctive rheologic behavio(u)r of tool of differentiating the topical adhesive compositions, just may topical adhesive be regarded as typical contact adhesive (PSA hereinafter referred to as) very difficultly.
In fact, known to the those of ordinary skill of adhesive field, the feature that PSA is different from the tool characteristic of other material that can temporarily cling article (the water between two glass plates) is its rheological parameters, particularly elastic modulus G ' along with the frequency change of the stress that is applied is very big.More specifically, when the frequency of the stress that is applied from typical bonding frequency change when typically peeling off frequency, promptly during hereinafter described 1 radian per second to 100 radian per second, the size of the G ' of PSA can increase more than the several magnitude.
Therefore, can draw: by under given frequency values, provide rheological parameters particularly the value of the G ' material that will plan to use to be defined as " topical adhesive " be unallowed.This may make the people misread, because under the situation that lacks other characteristic, will comprise the material that does not have real value.Therefore, rheological properties must be basis with the dynamic conditions.
This be not only applicable to elastic modulus G ', and ", therefore also be applicable to tan (δ)=G "/G ' that is applicable to viscous modulus G.Well-knownly being that not only the variation of G ' is bigger for typical PSA under the frequency of being considered, and G, " variation bigger, G " may level off to G ', perhaps even bigger than G ', promptly tan (δ) approximately or even greater than 1, particularly typically peeling off under the frequency.
Be not bound by theory, this can be interpreted as meaning that energy expenditure that major part is used for peeling off is binding agent (therefore can not cause effectively and peel off), although should cause very big cohesive force record value on the fact macroscopic view.
As mentioned above, be under as the rheological properties major part that material had of topical adhesive of the present invention as 37 ℃ reference temperature of human body normal body temperature and the frequency of certain limit under measure.Have now found that, when on as vitamin cream class articles for use, using topical adhesive, under lower frequency, form the binding agent contact, and under the speed of removing articles for use, peel off.This speed represents with the frequency of 100 radian per seconds, and has now found that the low frequency that forms adhesives is on the order of magnitude of 1 radian per second.Therefore, the used frequency range of the present invention is 1~100 radian per second.
The bonding characteristic that it is believed that selection binding agent under body temperature is the most suitable.Because topical adhesive of the present invention directly is applied on the skin, those of ordinary skills have the little specific heat capacity adhesive composition of (as preferably less than 4J/g/K) with selecting, the actual temperature of topical adhesive will reach very soon 37 ℃ or even before using by wearer's preheating.
For good bonding condition is provided, promptly under the frequency of 1 radian per second, the absolute value of elastic modelling quantity should be too not high, otherwise binding agent is too hard and can not closely connect or can't will match on adherent surface with it." have lower absolute value so that it also is important having good caking property, when using the articles for use frequently remove and to adhere to once more or to change, material keeps soft and can mildly be bonded to bonding good on the skin valuable especially to G simultaneously.
" 37 (1 radian per seconds) are important to ratio G ' 37/G, and these two values are equilibrated when guaranteeing on being bonded to skin.Simultaneously, in the frequency range of being considered, need the absolute change of restriction G ' 37.Therefore, should keep △ G ' 37 (being G ' 37 (100 radian per second)-G ' 37 (1 radian per second)) less with the ratio of G ' 37 (1 radian per second), so that pass in time or removing/keep the safety of topical adhesive to fix when peeling off, and can not cause uncomfortable.This also can represent with absolute value by △ G ' 37 is remained on below the particular value.
Importantly, ratio
Needing enough big promptly provides safety to bond and painless and remove easily so that the kinetic property of elasticity and viscous modulus guarantees a kind of like this relation.
At last, those of ordinary skills will appreciate that also glass transition temperature Tg, specific heat capacity and the specific heat conductance of adhesive composition are the useful parameters that is limited with the topical adhesive of usefulness more comprehensively.
Topical adhesive of the present invention preferably should satisfy following feature:
G '
37(1 radian per second) in the scope of 1500-20000Pa, preferred 1500-15000Pa, most preferably 3000-10000Pa;
