Abstract

The invention provides snail essence dry powder. The snail essence dry powder is prepared by the following steps that (1) snail slime is added to pure water for homogenate to obtain homogenate liquidI, the mixture is centrifuged, and ethanol precipitation essence is added; (2) the essence is centrifuged to obtain a precipitate I, the precipitate I is dissolved in ultrapure water for homogenate toobtain homogenate liquid II, and filtrate is obtained by suction filtration and then is concentrated under reduced pressure to obtain a concentrated solution; (3) the concentrate solution is centrifuged to obtain upper supernatant I, anhydrous ethanol is added, and the mixture is subjected to standing overnight and then subjected to suction filtration to obtain a snail essence crude extract; (4)the snail essence crude extract is added to pure water, the mixture is stirred until completely dissolved, then the mixture is centrifuged to obtain upper supernatant II, dialysis is carried out for 48h to obtain the essence; and (5) the extract is concentrated under reduced pressure, and then subjected to freeze-drying, and the extract is taken out and then ground to obtain the snail essence drypowder. The invention further discloses a preparation method and application of the snail essence dry powder. The snail essence dry powder has stable properties, has better effects of promoting skin regeneration, diminishing scar spots, and is convenient for storage and addition and use of different cosmetics.

Description

technical field [0001] The invention relates to a dry powder of snail essence and its preparation method and application. Background technique [0002] Snail mucus is the mucus secreted by snails when they crawl. It can effectively prevent skin aging and eliminate spots, scars and acne on the skin. The skin care cream made with the regeneration effect of snail is very protective to the skin. The natural allantoin, calcium, glycolic acid, collagen, protein and vitamins contained in the mucus secreted by snails are essential materials for making cosmetics. [0003] As a hot star product in the cosmetics and skin care industry in recent years - snail mucus has attracted much attention. Snail mucus has unique functions of tissue regeneration, stimulating cell growth, analgesic and anti-inflammatory, and has been widely used in the pharmaceutical and skin care industry. However, allantoin contained in snails is contained in snail mucus, and snail mucus is not only inconvenient...
