White fungus residue fermented product, skin-care detergent containing fermented product and preparation method of skin-care detergent

Abstract

The invention discloses a white fungus residue fermented product, a skin-care detergent containing the fermented product and a preparation method of the skin-care detergent. A yeast seed liquid is pumped into a fermentation medium to be fermented at 25-32 DEG C for 5-8 d, fermentation is ended when the glucose degree is smaller than 0.5 g/L, a fermented product is collected, and the white fungus residue fermented product is thus obtained. The skin-care detergent comprises the white fungus residue fermented product and white fungus residues. Biological surfactant sophorolipid in the white fungus residue fermented product serves as one of components of the skin-care detergent, compared with skin-care products with chemically synthesized surfactants, the skin-care detergent has lower toxicity, higher biodegradability, better environment compatibility, higher foamability, better selectivity and specificity under the conditions of the extreme temperature, pH and salt concentration and higher skin friendliness, cannot produce strong irritation to skin during usage and is safer.

Description

technical field [0001] The invention belongs to the field of applied biotechnology, and more specifically, the invention relates to a fermentation product of white fungus dregs and a preparation method thereof, as well as a washing and skin care product containing the fermentation product of white fungus dregs and a preparation method thereof. Background technique [0002] Surfactant is an essential component of raw materials for washing and skin care products. It plays the roles of wetting, emulsifying, foaming, thickening, solubilizing, and decontamination, and is widely used in actual production. [0003] Most of the surfactants added to the washing and skin care products on the market are artificial chemical synthesis. Such chemical surfactants often cause different degrees of pollution to the environment in actual production, such as changing the physical and chemical properties of the soil, polluting water bodies, etc., and are not easy to be degraded. In use, some ch...

Problems solved by technology

[0009] Fourth, the molecular structure of sophorolipids is complex and rich, which has a certain inhibitory effect on putrefactive bacteria

But the fermentation medium of rhamnolipid in this microbial detergent preparation method consists of soybean oil, sunflower oil, yeast extract and salts, there are still certain defects in the full utilization of resources

In addition, the rhamnolipid-producing bacteria is highly pathogenic Pseudomonas aeruginosa, if there is an error in the later purification process, the fermentation product will carry pathogenic bacteria, so there is a risk of contaminating the detergent, causing users cause serious harm
