Problems solved by technology

[0007]1. The silk reeling process generally requires high temperature treatment, so silkworm chrysalis protein has a high degree of thermal denaturation and poor solubility. If it is directly applied to the preparation of cosmetics, it will not Easily absorbed by the skin; it must be converted into a soluble substance that is easily absorbed by the skin;
[0008]2. Silkworm chrysalis protein is a substance with high protein content. Since some people are allergic to high protein, if the protein contained in it is directly used in the cosmetics industry, it will also Cause allergies in some users

Abstract

The invention relates to the technical fields of cosmetics and skin care products, particularly a silkworm pupa polypeptide skin-smoothing mask which comprises 5-10 parts of silkworm pupa protein polypeptide, 1-2 parts of rosemary essential oil, 1-3 parts of pomegranate seed extract, 1-6 parts of sea algae extract, 3-6 parts of glycerol, 1-4 parts of olive oil, 2-5 parts of caprylic / capric triglyceride and 1-3 parts of pearl powder. The silkworm pupa protein polypeptide is prepared by carrying out enzymolysis on the silkworm pupa protein by papain and Esperase proteinase. The combination of the active silkworm pupa polypeptide, rosemary extract, pomegranate seed extract and other active substances can help the skin to resist injury from free radicals and collagenase, thereby effectively preventing and resisting wrinkles from generation, enhancing the skin elasticity and postponing aging. The mask prepared from the silkworm pupa protein and plant extracts is natural and mild, and does not stimulate the skin; and under the synergetic effect of multiple active substances on the skin, the mask provided by the invention has better effects than common masks.

Description

[0001] technical field [0002] The invention relates to the technical field of cosmetics and skin care products, in particular to a silkworm chrysalis polypeptide skin rejuvenating mask, and also relates to a preparation method of the silkworm chrysalis polypeptide skin rejuvenating mask. Background technique [0003] silkworm chrysalis( silkworm pupa ), the chrysalis of Bombyx mori, the silkworm moth, is the main by-product of the silk industry. my country is a big country in the silk industry. There are hundreds of thousands of tons of leftovers from silk reeling factories every year. Silkworm chrysalis resources are extremely rich. However, due to the lack of deep processing technology, most silkworm chrysalis are used as feed or fertilizer, or even discarded directly. The resource utilization rate and The added value is low, resulting in great waste. [0004] Silkworm chrysalis contains a variety of active substances, among which the protein content of silkworm chr...
