Description

The present invention, while retaining the original skin familiarity of natural vegetable oils and fats, can be easily blended into an aqueous cosmetic composition, is excellent in skin familiarity, has no stickiness, and contains a novel base without oiliness. And a cosmetic composition containing the same.

Generally, polyglycerin fatty acid ester is used as an emulsifier for foods, but it has been widely used in recent years as a raw material for cosmetics because of its low irritation to the skin and safety. This polyglycerin fatty acid ester is also useful because its properties can be easily changed by changing the degree of glycerin polymerization, the composition of fatty acid, and the number of added moles. For example, Patent Document 1 contains substantially an alcohol. It is described that a water-based moisturizing cosmetic composition containing a polyglycerin fatty acid ester that does not have an excellent moisturizing effect.
However, when the above-mentioned polyglycerin fatty acid ester is blended in a water-based cosmetic, a polyglycerin fatty acid ester in which the number of moles of fatty acid added to the polyglycerin fatty acid having a high degree of glycerin polymerization is reduced is used, but the viscosity of the polyglycerin fatty acid ester is Since it is high and poor in water compatibility, there is a problem in usability, and stickiness or squeaking after application causes poor skin compatibility.

On the other hand, oil is blended for the purpose of protecting the skin, lips, hair and the like and retaining water, and is widely used in the field of cosmetics. Among them, petroleum-based oil components are used in cosmetics for the same purpose as described above, but they may lead to depletion of petroleum resources and increase of carbon dioxide gas, and may have storage and environmental risks. In addition, since many oils and fats of animal origin have a color, and many kinds of oils and fats have a odor, it is difficult to use in cosmetics.
Due to this background and the increasing awareness of natural ingredients by consumers in recent years, the use of vegetable ingredients has been particularly desired, and the development of cosmetics incorporating naturally derived vegetable oils and fats among oily ingredients has been carried out. There is. Naturally-derived vegetable oils and fats have the advantage that they are easily and inexpensively available. On the other hand, since the vegetable oils and fats are of natural origin, their quality is not stable, and they have a problem such as rancidity when stored for a long time.

Further, Patent Document 2 describes that a cosmetic using a vegetable oil component and an emulsifier suppresses stickiness to the skin after use and is excellent in a moisturizing effect and a rough skin improving effect. However, in cosmetics containing these oily ingredients, the feel of the oily ingredients affects the feeling of use, so depending on the oily ingredients and the amount used, the stickiness and oiliness to the skin were often not resolved. ..
In addition, since oil is basically only dissolved in an oily component, it is difficult to mix it with an aqueous cosmetic composition unless an emulsifier is used. I couldn't make the most of it.

Japanese Patent Laid-Open No. 2000-1422 JP-A-2000-119153

The results are shown in Table 1 below.

As can be seen from the results in Table 1, the base of the invention product 1 obtained by reacting the glycerin condensate of the present invention with the naturally occurring vegetable oil and fat and the dibasic acid has good skin familiarity and non-greasiness, Excellent results could be obtained in each evaluation of non-greasiness and presence of moist feeling. Furthermore, the invention composition 1 is a product composition of invention 2 in which 1,3-butylene glycol is added to the base of the invention product 1, and a cosmetic composition of invention product 3 is added in which dipropylene glycol is added. The same evaluation result as was obtained. Furthermore, a good evaluation result was also obtained for the cosmetic composition of Inventive Product 4 in which dipropylene glycol was added to the base obtained by reacting glycerin condensate having an average degree of condensation of 3, mango butter and eicosane diacid. I was able to get it. In addition, the cosmetic composition of Invention 5 in which a mixture of dipropylene glycol and glycerin is added to a base obtained by reacting a glycerin condensate having a condensation degree of 20, shea butter and succinic acid is also good. We were able to obtain the evaluation results.

With regard to the cosmetic composition of the invention product 6 using the base material to which the dibasic acid having 3 carbon atoms (malonic acid) was added, the results that could be used as a product could be obtained. In addition, the cosmetic composition of Invention 7 in which 1,3-butylene glycol was added to the base obtained by reacting a glycerin condensate having an average degree of condensation of 10, camellia oil and sebacic acid was also evaluated as good. I was able to get the result. Furthermore, the cosmetic composition of Invention 8 in which dipropylene glycol is added to the base obtained by reacting glycerin condensate having an average degree of condensation of 10, macadamia nut oil and succinic acid is also usable as a product.

Regarding the moist feeling, it has also been clarified that a cosmetic composition containing a base using shea butter gives better results than those using other vegetable oils and fats.
On the other hand, in the water dispersion of Comparative Product 1 produced only with the glycerin condensate and the naturally-derived vegetable oils and fats, a large amount of precipitate was observed and each evaluation test could not be performed. Furthermore, the water dispersion of Comparative Product 2 produced only with the glycerin condensate and the dibasic acid lacked in skin familiarity, was particularly sticky, and was inferior in moist feeling.

Next, the inventors of the present invention modified the amount of shea butter shown in Table 2 below according to the method for producing the cosmetic composition of the present invention (Invention Product 2) (Test Example 1 to 7) were produced, and a more preferable addition amount of vegetable oil according to the present invention was examined. Then, the 2% aqueous solution or aqueous dispersion of the cosmetic composition was evaluated for "presence or absence of moist feeling" in the same manner as in Example 1 above, and the stability test described below.
