preparation example 1

[0029] Wash and remove impurities from the altar laver, then dry it at 45°C, add appropriate amount of water (algae water ratio is 1:15), soak for 2 hours, and then soak in 5% sodium hydroxide solution for 12 hours (algae:alkaline ratio is 1:15) . After the alkaline immersion solution was stirred in a boiling water bath for 1 hour, it was washed with water and bleached with 0.08% hypochlorous acid solution for 2 minutes. This was followed by acidification with pH 1.28 hydrochloric acid for 5 minutes. Repeatedly wash the leaves to neutral. Add appropriate amount of water (the ratio of algae to water is 1:40), boil for 1 hour, filter, take the supernatant gel to freeze, and then dry at 45°C to obtain agar.

[0030] Make agar gel into a 1% solution, add citric acid to adjust the pH to 1-2, stir and react for 4.5 hours in a 60°C water bath, neutralize, concentrate under reduced pressure, add absolute ethanol (sample solution: ethanol = 1: 3), put in the refrigerator overnight. ...

Abstract

The invention provides applications of an agar oligosaccharide in cosmetics. The agar oligosaccharide has the structural molecular formula disclosed in the specification. The invention particularly provides applications of a degradation product of agar extracted from artificial red algae, such as purple laver, agar weed, Gracilaria or the like, in manufacturing cosmetic additives. The agar oligosaccharide can be used for preserving and absorbing moisture of the skin, and whitening the skin, and also can be used as a moisturizing agent, a moisture absorption agent or a whitening agent in cosmetics.

Description

technical field [0001] The invention relates to the application of an agar degradable oligomer, in particular to the application of the agar oligomer in the aspects of moisture absorption and whitening. Background technique [0002] The moisture and elasticity of the skin are closely related to the moisture in the skin. When the moisture in the skin is lost excessively, it will cause dryness, loss of elasticity and accelerated aging of the skin. Therefore, moisture absorption and moisturizing have always been one of the effects of skin care cosmetics. An ideal humectant should have good hygroscopicity and long-lasting and stable moisturizing function. Whitening is another effect of cosmetics. The main factor that determines skin tone is melanin in the skin. The depth of skin color is mainly determined by the ability of melanocytes to synthesize melanin. The production of melanin is related to the action of tyrosinase, dopaquinone tautomerase and 5,6-dihydroxyindole-2-carbo...
