Embodiment 1

[0036] (1) Preparation of laver crude polysaccharide

[0037] Soak the collected fresh Porphyra variegata in ethanol solution (mass concentration: 75%) for 12 hours, filter and dry, add the dried Porphyra into distilled water, wherein the dosage ratio of Porphyra variegata to distilled water is 1g: 20mL, soak the After 2 hours of porphyra tissue was mashed, heated at 90°C for 1 hour, cooled and filtered; the filtrate was concentrated under heating at 70°C (the filtrate was concentrated to 95% water content) and centrifuged, and ethanol solution (mass concentration was 75%) After alcohol precipitation for 24 hours, it was filtered, and the precipitate was freeze-dried to obtain the crude polysaccharide of laver.

Abstract

The invention belongs to the field of cosmetics, and in particular relates to a crude agar polysaccharide cream and a preparation method thereof. The crude agar polysaccharide cream comprises the following raw materials in percentage by weight: 0.1-0.5 percent of crude agar polysaccharide, 8-12 percent of a humectant, 0.5-1 percent of a preservative, 0.5-1 percent of an antioxidant, 2-4 percent of a nutrition additive, 10-15 percent of an oily raw material, 1-2 percent of a thickening agent, 0.2-0.4 percent of a metal ion chelating agent, 0.2-0.4 percent of a neutralizing agent, 1-2 percent of a whitening agent, 0.05-0.1 percent of an antisensitive agent, 0.3-0.5 percent of rose essential oil and the balance of deionized water. Tests prove that the total oxidation resistance of the cream is over 41mM / g, after the cream is continuously used for 6 days, the skin moisture content is increased by over 390 percent, the skin collagen fiber content is increased by over 200 percent, and the skin elasticity is improved by over 130 percent.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a seaweed crude polysaccharide skin cream and a preparation method thereof. Background technique [0002] Skin cream is a beauty and skin care product that is applied to the face. It forms a natural sebum film on the epidermis of the skin, replenishes moisture and nutrients to the skin, and at the same time repairs damaged cells on the epidermis of the skin, improving the elasticity, softness and elasticity of the skin. brightness. There are many types of skin creams, among which seaweed polysaccharide skin cream is added with seaweed polysaccharides, which can provide moisturizing, anti-oxidation, anti-radiation and other effects, and keep the skin delicate and shiny. [0003] Porphyra is one of the main edible economic seaweed species in my country, which belongs to Rhodophyta, Protoerythrophyta, Rubiolales, Rubiaceae, and Porphyra. The species of Porphyra are widely dist...
