The present invention relates to a novel multilayer cosmetic containing sodium lactate, and the object is to provide a product with high product value that has extremely excellent emulsivity during use and provides an unprecedented spreadable feel. It is something to do. In order to separate two mutually miscible liquids that have similar polarities, it is necessary to There is a method of widening the polarity difference between the two components by dissolving and adding substances with even lower polarity. Such an example is particularly notable in JP-A-49-1734. In JP-A-49-1734, a multilayer cosmetic was discovered that, by using sodium pyrrolidone carboxylate and a surfactant in combination, the aqueous layer and alcohol layer separate when left still and become emulsified when shaken. has been done. However, in order to satisfy the two conditions of this multi-layered cosmetic, which is to have an appropriate restoring time after shaking and to have a transparent (two-layered) structure, it is necessary to adjust the difference in the amount of each ingredient to an extremely large extent. is necessary, and this imposes a limit on the selection of raw materials. for example,
If the amount of sodium pyrrolidone carboxylate is large compared to other ingredients, the spread will be difficult, and if the amount of surfactant is large, skin irritation will generally increase, making it impossible to obtain a desirable cosmetic. Furthermore, multilayer cosmetics containing sodium pyrrolidone carboxylate have very poor emulsivity, and cannot provide the beautiful appearance desired as a cosmetic when shaken. The present inventor has overcome the above-mentioned drawbacks in multi-layer cosmetics, such as two-layer cosmetics consisting of an aqueous layer and an alcohol layer system, and three-layer cosmetics in which an oil layer is added thereto, while also improving the feel of the two-layer cosmetics. As a result of intensive research to find something superior to what is not available before, we finally completed the desired multi-layered cosmetic and arrived at the present invention. The present invention is a 50% to 70% aqueous solution of sodium lactate.
This product relates to multilayer cosmetics characterized by containing 90% ethyl alcohol and/or propyl alcohol, 5 to 35% ethyl alcohol and/or propyl alcohol, and 2 to 80% surfactants as essential ingredients, and has excellent emulsifying properties during use. It is a product that allows you to get an unprecedented feeling of elasticity, and it is also beneficial because it takes into account the properties unique to sodium lactate aqueous solutions, such as keratin softening effects and the ability to maintain a moisturizing effect against changes in temperature and humidity. The company aims to provide cosmetics. Next, the three components of the present invention (sodium lactate 50
% aqueous solution, ethyl alcohol, surfactant). Diagram (A): Sodium lactate (50% aqueous solution) (B): Ethanol (C): Surfactant (polyoxyethylene oleyl alcohol ether) From the above figure, the range in which the alcohol phase and aqueous phase separate is expressed in weight percent, and for each component, 20≦(A)≦
90, 5≦(B)≦35, 12≦(C)≦80, and A+
This is a range where B+C=100. A part of the content ratio of the components of the multilayer cosmetic according to the present invention was determined based on the above results. The sodium lactate aqueous solution applied to the present invention is 50
A concentration of ~70% is desirable, and it may be a commercially available product or one obtained by appropriately diluting sodium lactate in an aqueous solution, as long as it constitutes this concentration range in the final product. The generation process does not matter. Suitable alcohols for use in the present invention are ethyl alcohol and propyl alcohol.
The surfactant may be one that is normally used in lotions, but preferably those with an HLB of around 10 such as polyoxyethylene oleyl alcohol ether, polyoxyethylene sorbitan fatty acid ester, and polyoxyethylene hydrogenated castor oil derivatives are preferred. selected. Next, the results of a sensory test obtained when 50 women used the cosmetic (facial oil) of the present invention continuously for 7 days will be shown in comparison with conventional cosmetics.

照）[Table] The aqueous layer-alcohol layer multilayer cosmetic of the present invention not only exhibits a beautiful appearance when left still by adding oil agents with different specific gravities, but also has various base materials, It is possible to stably incorporate medicinal ingredients, fragrances, etc., and it also has an unprecedented good emulsifying property even when shaken, so it can provide a desirable appearance as a cosmetic. The reason why the multi-layered cosmetic of the present invention has good emulsifying properties is still unknown, and there are various possible explanations, but it is probably due to its chemical structure, which has relatively higher polarity and molecular weight than conventional sodium pyrrolidone carboxylate. This is probably because it is small. (See table below)
