preparation example Construction

[0034] The preparation method of plant ferment among the present invention is as follows:

[0035] Take plant leaves, crush them through a 60-100 mesh sieve, add 50-75g / L to deionized water, and add 10g / L of glucose at the same time to adjust the pH of the system to 4.5-5.0;

[0036] Sterilize the fermentation medium at 121°C and 0.1Mpa for 20 minutes to prepare the sterilized fermentation medium;

[0037] Inoculate Lactobacillus plantarum in MRS medium, culture at 37°C, 200rpm for 18-24h, until the bacterial concentration reaches 10 6 ~10 7 In the case of CFU / mL, inoculate 5% to 10% of the inoculum in the sterilized fermentation medium for fermentation and culture, and filter with a ceramic membrane to obtain the Centella asiatica fermentation filtrate; wherein,

[0038] Plantarum inoculated with Lactobacillus plantarum was cultured at 35±2°C and 200rpm for 48-72h, and when the residual sugar reached 0, the fermentation was terminated; after fermentation, the fermentation l...

Embodiment 1

[0041] Prepare the sample according to the raw material ratio in Table 1, mix the active substance, oil, light stabilizer, and antioxidant to obtain the oil phase, and heat it in a water bath with magnetic stirring until it is completely dissolved;

[0042] Mix the emulsifier, co-solvent, plant enzyme and chelating agent to obtain the water phase, heat and stir in a water bath until completely dissolved;

[0043] Add the oil phase to the water phase, disperse at 15000rpm at high speed, disperse for 3 minutes, and then use high-pressure homogenization technology, 80MPa, and cycle 6 times to prepare the obtained sample.

Abstract

The invention discloses a low-irritation plant enzyme whitening nano composition, and a preparation method and application thereof. The low-irritation plant enzyme whitening nano composition comprises a fat-soluble whitening active matter, plant enzyme, grease, a cosolvent, an emulsifier and other additives, wherein the whitening active matter accounts for 0.1%-10%; the grease accounts for 1%-10%; the cosolvent accounts for 20%-60%; the emulsifier accounts for 0.5%-10%; the other additives account for 0.1%-1%; the balance is the plant enzyme; and the whitening active matter is one or more of phenethyl resorcinol, 4-butyl resorcinol and hexylresorcinol. According to the invention, the plant enzyme and the whitening active matter are combined for use, so that the irritation of the whitening active matter can be reduced while the effective use concentration of the whitening active matter is improved, and the applicability of the whitening active matter is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of micro-nano carriers, and in particular relates to a low-irritation plant enzyme whitening nano composition, a preparation method and an application thereof. Background technique [0002] Along with the raising of living standard, people pay more and more attention to skin care (especially the care and maintenance of facial skin). [0003] In recent years, people have higher and higher requirements for cosmetics necessary for life, not only requiring better efficacy, but also paying great attention to the safety problems of the skin caused by them. [0004] At present, the following problems generally exist in the whitening skin care products on the market: it is difficult to achieve the significant effect expected by consumers when used at low concentrations; more serious contact dermatitis, allergies and other problems will occur when the usage is increased, which is manifested as redness and swelling of...
