Detackifying Composition

Detailed description of the invention

The present invention relates to a composition containing a mixture of detackifiers. More specifically, the present invention provides a mixture for an emulsion-type human protection product such as hand lotion, roll-on and creamy deodorant and antiperspirant, in which silicone fluid and silicone wax are mixed in a special proportion. It relates to a detackifying composition containing.

This application is a continuation of application number 51,592, filed June 25, 1979.

For many years various products and formulations have been used or treated on human skin. Various formulations have been used on human skin to keep the skin smooth and supple or to treat or prevent any condition or unfavorable properties of the skin. Many of the formulations used for this purpose are in the form of emulsions, in which in many cases so-called detackifiers have been proposed, but generally unsuccessful, in order to solve the inherent tackiness of cosmetically acceptable emulsions. An important reason is that the detackifying agent to be used in the human protective product should be capable of local application of the human body and should be compatible with the components commonly used in such preparations.

It is an object of the present invention to provide an improved detackifying composition.

It is another object of the present invention to provide an improved detackifying composition for use in emulsion-type human protective products.

Another object of the present invention is to provide an improved detackifying composition containing a special blend of silicone fluid and silicone wax.

Other objects of the present invention will be understood from the following detailed description of the invention.

The above-mentioned title and features and advantages of the present invention are obtained by compositions containing special blends of detackifiers. In particular these objects are achieved by special blends of silicone fluids and silicone waxes which exhibit a desirable detackifying effect when used in emulsion-type human protective products.

As used herein, "silicone fluid" refers to a silicone polymer that is fluid at body temperature and insoluble in water and cosmetic oils.

As used herein, "silicone wax" refers to a silicone polymer that is solid or semisolid at body temperature, insoluble in water, insoluble or only slightly soluble in cosmetic oils.

The detackifying composition of the present invention contains a mixture of silicone fluid and silicone wax in a ratio of 9: 1 to 1: 3, preferably about 1: 1.

Silicone fluids effective in the present invention are dimethicone, methicone and cyclomethicone. Dimethicone is exemplified by polydimethyl siloxane having a molecular weight of about 500 to about 26,000. Methicone is exemplified by polymethyl hydrogen siloxane having a molecular weight of about 500 to 23,000. Examples of the cyclomethicone include cyclic tetramers of dimethyl siloxane having a molecular weight of about 296 or cyclic pentamers of dimethyl siloxane having a molecular weight of about 370. These silicone fluids are readily available from a variety of manufacturers, including Dow Corning, General Electric, SWS and Union Carbide, under various trade names (e.g. 200 Fluids, SF 96 Fluids and SWS 101 Fluids), and are suitable for local application in the human body. .

Silicone waxes effective in the present invention are stearoxy dimethicone and dimethicone copolyols. Stearoxy dimethicone is exemplified by stearoxy dimethylsilane having a molecular weight of about 343 or disteaoxy dimethylsilane having a molecular weight of about 586. The dimethicone copolyol is exemplified by dipolyoxyethylene dimethyl silane having a molecular weight of about 1600 to 2000. These silicones are readily available from manufacturers such as Dow Corning and SWS under various trade names (eg QF Waxes and F Copolomers) and are suitable for local application in the human body.

As mentioned above, the detackifier should be used with a ratio of silicone fluid to silicone wax of 9: 1 to 1: 3, preferably about 1: 1.

When a mixture of the detackifying agent is used outside the above ratio range, significant loss of the desired detackifying property may occur. It is evident that at least about 1 part of the detackifying composition of the present invention should be used for 5 parts of each tacky component present in various products. Thus, it can be seen that the amount of detackifying composition used depends on the amount of tacky components present in the various emulsion-type human protective products and the actual amount of detackifying composition may vary with each formulation. .

The detackifying composition of the present invention is effective in emulsion-type human protective products such as hand lotions, rool-ons and cream deodorants and antiperspirants, humectants, moisturizers, systemic creams, make up preparations and the like. The present inventors are not limited to the following musk, but since the system is formed from an oil and water mixture when the water evaporates in the emulsion zone, de-tacking at both stages is necessary, and thus the de-tacking of the present invention. The composition works successfully, whereas the same detackifier does not work successfully when used alone. When the silicone fluid detackifiers are used alone, these detackifiers are effective only in the emulsion zone, and are not effective when water evaporates from the emulsion zone, and when the silicone wax detackifiers are used alone, Tackifiers have been shown to be effective only when water is evaporated to leave an oil film. Thus, the compositions of the present invention are effective at each step of the emulsion zone, suggesting that they impart a complete detackifying effect to the emulsion-type human protective product.

Each embodiment of the present invention is described by the following examples. However, the present invention is not limited to the matters described in the appended claims, but in each of the embodiments.

As can be readily seen above, instead of the detackifying mixture of the present invention used in the hand lotion formulation of Example I, the hand lotion formulation of Example II contains the mineral oil proposed to be effective as a detackifier in the prior art. Used.

The detackifying property of the composition of the present invention is evaluated by the following two test methods. One method is performed by a tactile or skin feel test by a panel test of trained assessors as follows. Wash your hands with soap and water, dry them thoroughly, and apply a certain amount of hand lotion. Apply the lotion onto the skin and rub the skin in a constant motion until the aqueous part of the lotion evaporates. The lotion applied to the hands of the evaluator will not appear from the skin surface. The time required for rubbing from the application of the lotion to the extinction point is evaluated as the following skin feel characteristics, for example, adhesiveness, lubricity and oiliness. These characteristics were compared with arbitrary standard values, and the evaluation index for each characteristic was divided into grades 1 to 5 to evaluate various lotions. In determining the grade, an index of 1 was used to show the most excellent characteristics.

The second test involves using panel testers to provide consumers with products in two containers (eg hand lotion) and ask for the results of using the lotion in each container for a week. Distribute the questionnaire to the consumer and, when using the good or bad for each product and the attributes of each product, such as hand lotion, describe the characteristics such as stickiness and recover.

As a result of performing each of the above-described tests with the compositions of Examples I and II, the hand lotion composition of Example I was clearly demonstrated by the trained evaluator and the consumer with no stickiness compared to the composition of the hand lotion of Example II. Has been proven.
