Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing detergent which uses a polyglycerol fatty acid ester, has a transparent appearance and good temperature stability, and is particularly compatible with makeup cosmetics. It is suitable for hard make, and when it comes in contact with water, it instantly forms an O / W emulsion, so it has excellent water washability, and has a fresh feeling without residual oil after use. It concerns a certain cleansing cleanser. [0002] Polyglycerin fatty acid esters which are useful as surfactants in pharmaceuticals, cosmetics and foodstuffs are:
It is obtained by esterifying a fatty acid and polyglycerin. Polyglycerin of the mother nucleus is obtained by condensation of glycerin or reaction of glycerin with glycidol, etc., but generally, it is often by condensation of glycerin. As described above, since polyglycerin fatty acid ester uses glycerin as a starting material, it is a surfactant having low skin irritation and good safety. For this reason, the use of polyglycerin fatty acid esters for the purpose of improving safety has been increasing. [0003] Until now, cleansing oil, one of the cleaning agents, was a special product only for hard make, but recently, it has been sold to a wide range of people from light make to hard make. It is a product whose sales volume is growing due to its excellent usability (cleansing ability, simplicity, etc.) and the trend of consumers. The wash-out type is the mainstream, and the main components are an oil that is familiar with the make and a surfactant for washing away. O when washing off
The point of this product is the selection and combination of surfactants to form a / W emulsion. At present, most of the surfactants used are nonionic surfactants having a polyoxyethylene chain, and have a problem in safety. For this reason, highly safe polyglycerin fatty acid esters have been studied. However, they have poor transparency in appearance, and lack the function of instantaneously forming an O / W emulsion when they come in contact with necessary water as a function. Therefore, there is a problem such as stickiness due to a feeling of residual oil after use. [0004] Accordingly, an object of the present invention is to provide a cleansing detergent, particularly a make-up cosmetic, which uses a highly safe polyglycerin fatty acid ester and has a transparent appearance and good temperature stability. Good familiarity, suitable for hard make, and instantaneous O / W when in contact with water
An object of the present invention is to obtain a cleansing cleansing agent which is excellent in water-washing properties because of forming an emulsion, has no residual oil feeling even after use, and has a refreshing feeling of use. The present inventors have made intensive studies to achieve the above object, and as a result, have found that certain polyglycerin fatty acid esters, maltitol hydroxy aliphatic ethers and / or alkyl glucoside surfactants have been developed. The present inventors have found that a cleansing detergent containing an agent can solve the above problems, and have completed the present invention. That is, the present invention relates to (A) an ester of polyglycerin having an average degree of polymerization of 3 or more and one or more fatty acids selected from saturated or unsaturated fatty acids having 8 to 22 carbon atoms. A polyglycerol fatty acid ester having an HLB of 8.0 or more, and (B) a general formula (1) (Where A is a residue obtained by removing n hydroxyl groups from maltitol, R ₁ and R ₂ are a hydrogen atom, an alkyl group having 1 to 20 carbon atoms or a branched alkyl group, and n represents an integer of 1 to 3) A cleansing detergent containing maltitol hydroxy aliphatic ether and / or an alkyl glucoside surfactant represented by the formula (1), wherein the amount of the component (A) is 1.0 to 25.0% by weight and The present invention relates to a cleansing detergent containing 0.5 to 15.0% by weight of the component (B). Hereinafter, the present invention will be described in detail. The polyglycerin fatty acid ester used in the present invention is an ester of polyglycerin having an average degree of polymerization of 3 or more and one or two or more fatty acids selected from saturated or unsaturated fatty acids having 8 to 22 carbon atoms. And a polyglycerol fatty acid ester having an HLB of 8.0 or more. The fatty acid constituting the polyglycerin fatty acid ester may be any of linear and branched fatty acids. Examples of such polyglycerin fatty acid esters include esters of polyglycerin having a polymerization degree of 3 to 10 and higher fatty acids having 8 to 22 carbon atoms, such as tetraglyceryl monolaurate, hexaglyceryl monolaurate, decaglyceryl monolaurate, and decayl dilaurate. Glyceryl, hexaglyceryl monomyristate, decaglyceryl monomyristate, decaglyceryl dimyristate, decaglyceryl monopalmitate, decaglyceryl monostearate, decaglyceryl distearate, hexaglyceryl monooleate, decaglyceryl monooleate, diolein Decaglyceryl acid,
Decaglyceryl monoisostearate, decaglyceryl diisostearate and the like.
Use more than seeds. Among them, polyglycerol fatty acid esters having an HLB of 11 or more are particularly preferred. For example,
Hexaglyceryl monooleate, decaglyceryl diisostearate and the like. It is also possible to appropriately use a polyglycerin fatty acid ester of less than 8.0 and a polyglycerin fatty acid ester of more than HLB 8.0 at a ratio of HLB 8.0 or more. [0008] In the cleansing detergent of the present invention, the above-mentioned polyglycerin fatty acid ester is used in an amount of 1.0 to 25.0% by weight, preferably 5.0 to 15.0% by weight. 1.
If the amount is less than 0% by weight, no cleansing detergent can be obtained, and if the amount of the cleansing detergent used exceeds 25.0% by weight, it is difficult to instantaneously form an O / W emulsion when coming into contact with water. The desired performance cannot be obtained, which is not preferable in use. The maltitol hydroxy aliphatic ether used in the present invention is represented by the following general formula (1). Embedded image (Where A is a residue obtained by removing n hydroxyl groups from maltitol, R ₁ and R ₂ are a hydrogen atom, an alkyl group having 1 to 20 carbon atoms or a branched alkyl group, and n represents an integer of 1 to 3) In the general formula (1), examples of the C _{1 to} C ₂₀ alkyl group or the branched alkyl group which are specific examples other than the hydrogen atom of R ₁ and R ₂ include a methyl group, an ethyl group,
Isopropyl group, pentyl group, hexyl group, heptyl group, octyl group, lauryl group, myristyl group, palmityl group, stearyl group, 2-ethylhexyl group, isostearyl group, and the like, and one or more of these are used. . Of these, those having a lauryl group or a myristyl group are particularly preferred. The alkyl glucoside surfactant used in the present invention includes alkyl glucosides such as octyl glucoside, nonyl glucoside, decyl glucoside, dodecyl glucoside, lauryl glucoside, myristyl glucoside, and palmityl glucoside.
