Benefits of technology

"The present invention provides a composition (I) containing a plant sterol ester, which is prepared by fatty acid esterification of plant sterol wax. This composition (I) can be used as an additive in hair cosmetics to increase their feeling effects. The additive can be mixed with vegetable oil and / or a (partially) hydrogenated vegetable oil to provide a lanolin-like or hard lanolin-like feeling. Additionally, the additive can also include a sucrose fatty acid ester and a liquid higher fatty acid to further enhance the feeling effects. The additive is safe, cost-effective, and easy to mix with hair cosmetics. It can provide similar benefits to those provided by lanolin, such as repairing damaged hair and providing a moist and oily feeling."

Problems solved by technology

However, lanolin has an original odor and a problem to cause allergy.
In addition, animal-derived substances are generally unfavored because of health damages caused by the animal-derived substances such as BSE (bovine spongeform encephalopathy) in recent years.
If the synthetic materials are orally or percutaneously absorbed, health problems may occur.
In addition, the synthetic materials do not act mildly and are not benign to human as compared with natural products.
However, none of the above-mentioned cosmetics has been developed for substituting for lanolin.
Accordingly, such cosmetics can not provide a moist feeling, an adequate oily feeling, and luster that are derived from lanolin.
However, any of the above-mentioned cosmetics use phytosterols or phytosterol fatty acid esters that are obtained by preparing alone or separating, resulting in high costs from an industrial view point.
Accordingly, the pytosterols or the phytosterol fatty acid esters are not suitable for use in the cosmetics or a skin care preparation.

preparation example 1

[0074] 2000 g of a deodorized distillate (the total tocopherol content of 10.3%, acid value of 81) obtained by deodorizing soybean oil as a by-product was methyl-esterificated in a mixed solvent of 100 ml of methanol and 1000 ml of toluene in the presence of 130 g of sulfuric acid under ref lux for 1 hour. An oily substance was separated, and washed four times with 500 ml of water. The acid value was 1 after the methyl-esterification. The resultant product was cooled to room temperature, and deposited crystal was filtered and separated. 8.9 g of the crystal was removed by the filtration.

[0075] A column was filled with 2000 ml of a strong basic anion exchange resin, “Amberlite IRA958”, to be an OH type, which was then replaced with toluene. Then, a solution of the prepared methyl-esterificated oil in toluene was passed therethrough. 4000 ml of toluene flowed through the column to wash the resin, and removed to provide 1670 g of non-adsorbed oil. The tocopherol adsorbed was eluted by...

[0078] 2000 g of a deodorized distillate (the total tocopherol content of 9.8%, acid value of 78) obtained by deodorizing vegetable oil (a 1:1 mixture of soybean oil and rapeseed oil)as a by-product was methyl-esterificated in a mixed solvent of 1000 ml of methanol and 1000 ml of toluene in the presence of 130 g of sulfuric acid under reflux for 1 hour. An oily substance was separated, and washed four times with 500 ml of water. The acid value was 1 after the methyl-esterification. The resultant product was cooled to room temperature, and deposited crystal was filtered and separated. 9.2 g of the crystal was removed by the filtration.

[0079] A column was filled with 2000 ml of a strong basic anion exchange resin, “Duolite A113” to be an OH type, which was then replaced with toluene. Then, a solution of the prepared methyl-esterificated oil in toluene was passed therethrough. 4000 ml of toluene flowed through the column to wash the resin, and removed to provide 1650 g of non-adsorbed...

Abstract

A safe additive that increases the feeling effects from a hair cosmetic is provided at low costs. The additive that increases the feeling effects has less stickiness, can be easily and uniformly mixed with hair cosmetics, and can provide feelings, effects and advantages that are similar to those of sterol wax and lanolins including lanolin itself, liquid lanolin, and hard lanolin. The additive that increases the feeling effects comprises a composition (I) prepared by distillation, fatty acid esterification, decoloring, and deodorization of a by-product obtained when tocopherol is extracted, separated and purified from a vegetable oil deodorized distillate.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a composition suitable for an ingredient of hair cosmetics such as a hair setting agent, a hair conditioning agent, a finishing agent, a hair coloring agent and a waving agent. Furthermore, the present invention relates to a feeling improver of the hair cosmetic, i.e. an additive that increases the feeling effects from of the hair cosmetic that can provides excellent properties, effects and advantages. DESCRIPTION OF THE PRIOR ART [0002] Conventionally, lanolin (wool fat) has been used for various hair care products. For example, lanolin can provide hairs and skins with a moist feeling, an adequate oily feeling and luster, and therefore is added to cosmetics including hair cosmetics, emulsions, creams, lip sticks and lotions Also, lanolin has excellent emulsification stability and emollient, and can be used as an emulsifying auxiliary agent, stabilizing agent and a softening agent. [0003] However, lanolin has an original...
