JPH06293624A - Emulsion type cosmetic - Google Patents

Abstract

PURPOSE:To obtain an emulsion-type cosmetic having high moisture-retaining effect only by the addition of a small amount of a betaine having excellent moisture-retaining action and touch-improving action, giving extremely good touch after use by including the betaine as an active ingredient. CONSTITUTION:This emulsion type cosmetic contains a betaine expressed by the formula (another name: trimethylglycine, glycine betaine or alkyldimethyl be taine) as an active ingredient. The betaine expressed by the formula is included in an amount of 0.05-20 pts. wt., preferably 2-5 pts. wt. This emulsion type cosmetic can contain, e.g. a hydrocarbon such as squalane, oils and fats such as oilve oil, wax such as lanlin, a fatty acid such as stearic acid, a higher alcohol such as cetanol, synthetic ester such as glycerol triester, other oil component, a thickening agent such as quince seed, an alcohol such as ethanol, a surfactant such as glycerol monostearate, an alkali such as triethanolamine, a chelating agent, a preservative, an antioxidant, a perfume, a pigment, a humectant, a buffer and other chemicals, etc., in addition to the essential ingredient.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsion cosmetic containing betaine (also known as trimethylglycine, glycine betaine, alkyldimethyl betaine) as an active ingredient. The emulsified cosmetic product according to the present invention refers to a substance produced by emulsifying an aqueous phase and an oil phase and used on the skin, and is represented by an emulsion or a cream.

[0002]

BACKGROUND OF THE INVENTION Conventional moisturizers for emulsion cosmetics include glycerin, propylene glycol, sorbit, polyethylene glycol, dipropylene glycol, 1,3-butylene glycol, diglycerin, mannitol and POE methyl. Glycosides,
Other biopolymers have been used, but not only their effects are not sufficient, but they also have drawbacks such as long-lasting effects, stickiness and slippage, etc. It wasn't a gain.

On the other hand, regarding the effect of applying betaine to the skin, JP-A-3-11009 describes a wrinkle-preventing effect by the combined use of ATP or an ATP producing system, magnesium salts, and potassium salts, but it is used alone. The effect of is not known so far.

[0004]

Means for Solving the Problems The inventors of the present invention have earnestly studied to obtain a compound having an excellent moisturizing action as an emulsified cosmetic product. As a result, the above betaine has an excellent moisturizing action and touch improving action. Then, the present invention was completed. That is, the present invention is an emulsion cosmetic containing betaine represented by the formula (1) as an active ingredient.

For example, betaine is soluble in 160 parts by weight with respect to 100 parts by weight of water, and its moisturizing property was examined. The values shown in Table 1 were obtained.

[0006]

[Table 1]

[0007] The compounding amount of betaine of the formula (1) is 0.05 to 0.5% of the final product.
10 parts by weight, preferably 2 to 5 parts by weight.

In addition to the above-mentioned essential components, the emulsified cosmetic of the present invention contains substances usually used in emulsified cosmetics such as hydrocarbons (squalene, liquid paraffin, petrolatum, solid paraffin, microcrystalline wax, ceresin, etc.), oils and fats ( Olive oil, almond oil, cacao butter, jojoba oil, macadamia nut oil, avocado oil, hydrogenated palm oil, castor oil, sunflower oil, evening primrose oil, synthetic triglyceride, etc.), wax (beeswax, lanolin, carnauba wax, candelilla wax, etc.), fatty acid (stearic acid,

Other oil phase components (silicone oil, etc.), thickeners (quins seed, pectin, cellulose derivative, xanthan gum, sodium alginate, soagina, carboxyvinyl polymer, etc.), alcohols (ethanol, isopropyl alcohol, etc.), surfactants (monostearin) Acid glycerin, POE sorbitan fatty acid ester, sorbitan fatty acid ester, POE alkyl ether, PO
E / POP block polymer, POE hardened castor oil ester, fatty acid soap, sodium alkylsulfate, etc.), alkali (sodium hydroxide, potassium hydroxide, triethanolamine, etc.), chelating agent (ethylenediaminetetraacetic acid / 2 sodium, etc.), preservative (Parabens, sorbic acid, isopropyloxymethylphenol, phenoxyethanol, etc.), antioxidants (dibutylhydroxytoluene, vitamin E, etc.), fragrances, dyes, moisturizers (glycerin, propylene glycol, sorbit, polyethylene glycol, dipropylene glycol, 1,3-butylene glycol, diglycerin, mannitol, PO
E-methyl glycoside, other biopolymers, buffers (citric acid, sodium citrate, lactic acid, sodium lactate, etc.), other drugs (vitamins, UV absorbers,
Amino acids, whitening agents, etc.) can be added.

The emulsified cosmetic of the present invention can be manufactured, filled and distributed according to a method usually used.
