Description

Cosmetic soap composition

The present invention relates to a cosmetic soap composition containing apricot seed oil, vitamin E acetate and polyethylene glycol having good cosmetic effects on the skin and physical properties and stability of the cosmetic soap.

In general, the cosmetic soap is alkaline in aqueous solution during skin cleansing, when frequently used, removes sebum components of the skin, softens the stratum corneum, there is a problem that the skin is dried and rough.

Therefore, various additives have been proposed to solve this problem. In particular, U.S. Patent No. 4,169,067 is suggested to have good skin properties and bubbles by using higher fatty acids and polyethylene oxide of 100,000 to 5,000,000, but because of the high content of higher fatty acids, deterioration occurs during long-term storage after soap production, and molecular weight of 100,000 to When 5,000,000 polyethylene oxide is used, it is difficult to mix in soap, and the mixed hardness is too high. In addition, hyperlipidemic agents such as fatty acids and fatty acid derivatives, vegetable and animal fats, fatty alcohols, lanolin derivatives, ginseng extracts, cucumber extracts, and the like, were used to give skin softening and moisturizing effects. Since the hyperlipides and plant extracts are dispersed in an aqueous soap solution and adsorbed on the skin, the skin feels good after washing, and there is a cosmetic effect on the skin. Problems such as discoloration and discoloration due to long-term preservation and solubility due to the addition of a large amount are quickly consumed due to high solubility and low hardness. In addition, U.S. Patent No. 3,511,783 is an antioxidant (stabilizer) of hyperfatty soap added with higher fatty acids, such as ethane hydroxy-diphosphonic acid (EHDP) and ethylene diamine tetraacetic acid (EDTA). It has been suggested to prevent, but when using a mixture of EHDP and EDTA is irritating to the skin, if you use a small amount so that there is no irritation on the skin can not prevent the deterioration, when using a large amount of high-quality fatty acids, there is a problem that the hardness of the soap falls .

The present inventors have conducted a lot of research to solve the above problems, using apricot oil, vitamin E acetate, polyethylene glycol is excellent in the beauty effect on the skin, there is no problem of deterioration due to long-term storage, Soap, solubility, hardness and the like properties of the general soap could be prepared.

Apricot seed oil used in the present invention is an oil obtained by compressing the seeds of apricots obtained from apricot tree or apricot tree, which are mostly olein oil, and olein oil is a kind of sebum component present in the skin, and when used on the skin, Formation is excellent in affinity with the skin, excellent skin softening effect, there is a function to protect the skin from external stimulation according to the formation of the film. Apricot seed oil also contains a small amount of Amygdalin (Amygdalin), which has a natural bactericidal effect, which is good for skin cleanliness. However, when a large amount of apricot seed oil is used, there is a problem of discoloration, discoloration, etc. when stored for a long time due to the high content of ole oil, and the result of using a mixture of vidamine E acetate to solve this problem, the stability is remarkably improved.

Vitamin E Acetate is acetate that is stabilized to stabilize vitamin E. When used on the skin, it acts synergistically on the antioxidant activity of keratin, a constituent protein of skin tissue, and prevents skin oxidation. It has peripheral vascular expansion effect and promotes skin blood circulation. In addition, by inhibiting the oxidation of unsaturated fats and oils in the components of sebum, it suppresses the production of peroxides, thereby alleviating irritation to the skin.

However, when apricot seed oil and vitamin E acetate are added to the cosmetic soap, both ingredients are fine when added in liquid form. However, when a large amount is added to the skin for cosmetic effects, it is difficult to reduce the hardness of the soap and make it difficult to prepare. There is a problem. As a result of mixing polyethylene glycol to solve these problems, it improves the solubility and hardness of soap, increases the foaming ability, and manufactures a cosmetic soap that can sufficiently effect the skin effect of apricot seed oil and vitamin E acetate. Could.

That is, the present invention is in the alkali metal soap 0.05 to 5 parts by weight, preferably 0.1 to 3 parts by weight of apricot seed oil, 0.05 to 5 parts by weight of vitamin E acetate, preferably 0.1 to 3 parts by weight, polyethylene glycol 0.1 to 10 It relates to a composition consisting of parts by weight, preferably 0.2 to 5 parts by weight, and has a superior skin-care effect, good stability, excellent solubility and hardness as compared to general cosmetic soaps and cosmetic soaps containing overfat or plant extracts. The present invention relates to a cosmetic soap composition.

The present invention is described in detail as follows. In the composition of the present invention, the alkali metal soap is an alkali metal salt of a fatty acid having 10 to 20 carbon atoms, wherein the fatty acid is palm oil, palm oil, soybean oil, castor oil, olive oil, palm kernel oil, vegetable oil, tallow oil, sun palm, fish oil, etc. Obtained from animal fats and alkali metals, either alone or mixed with sodium or potassium to neutralize with fatty acids to produce alkali metal soaps. Apricot seed oil is oil produced by pressing or solvent extraction method from apricot seed, and has a saponification value of 180 to 200, an iodine value of 90 to 120, and an acid value of 2 or less. Vitamin E acetate may be used by acetate-forming natural vitamin E, or synthetic vitamin E may be used. Polyethylene glycol is prepared by polymerizing ethylene oxide, and may be used if the number of moles of ethylene oxide is 10 moles or more, but preferably 50 to 350 moles of ethylene oxide mole number.

The cosmetic soap composition of the present invention may contain any component conventionally used for cosmetic soap. Normally, the cosmetic soap contains about 8 to 20 parts by weight of water, and a conventional antioxidant, butylated hydroxytoluene (BHT), is added to 0.1 parts by weight or less, and a conventional metal ion blocking agent is 0.2. It is added in weight part or less. In addition, about 5 parts by weight or less of conventional fragrances, pigments, dyes and the like can be added, and 3,4,4'-trichlorocarbanilide, 4,4'-dichloro-3- (trifluoro), which is a conventional antimicrobial agent 0.1-3 parts by weight of methyl) carbanilide, 3, 4, 5-tribrosalicyla-anilide alone or mixed may be added, and 0.1-10 parts by weight of a generally known synthetic surfactant may be added.
