Embodiment 1

[0059] (3) Filtrate the insoluble matter from the material after deactivating the enzyme to obtain a light yellow, clear and transparent solution. The polypeptide solution is passed through an ultra-microfiltration membrane to collect the filtrate with a molecular weight below 3000 Da;

[0060] (4) Add 4% activated carbon to the obtained polypeptide solution for adsorption and decolorization, after desalination treatment by macroporous resin DA201-C, vacuum concentration, freeze-drying to obtain silkworm chrysalis protein polypeptide dry powder, and set aside.

[0061] Step 2: Preparation of Silkworm Chrysalis Polypeptide Day Cream

[0062] (1) Add 1 part of xanthan gum, 1 part of cetostearyl alcohol, 0.1 part of glutathione, 1 part of azone, 1 part of seaweed polysaccharide, 0.1 part of isopropanol, and 40 parts of normal saline into the container and stir. When the temperature reaches about 80°C, keep warm for later use;

[0063] (2) Put the above mixture in a vacuum homoge...

Embodiment 2

[0068] The silkworm chrysalis protein polypeptide prepared by other methods is prepared in the same way as that described in "Food Science" 2008, Vol 29, No. 11, "Experimental Research on the Anti-tumor Effect of Silkworm Chrysalis Protein Polypeptide Liquid", pp. 588-589.

Embodiment 3

[0078] (3) Filtrate the insoluble matter from the material after deactivating the enzyme to obtain a light yellow, clear and transparent solution. The polypeptide solution is passed through an ultra-microfiltration membrane to collect the filtrate with a molecular weight below 3000 Da;

[0079] (4) The obtained polypeptide solution was decolorized by adding 5% activated carbon for adsorption, desalinated by macroporous resin DA201-C, concentrated in vacuo, and freeze-dried to obtain silkworm chrysalis protein polypeptide dry powder for future use.

[0080] Step 2: Preparation of Silkworm Chrysalis Polypeptide Day Cream

[0081] (1) Add 1 part of glycerin, 1 part of azone, 0.1 part of propyl p-hydroxybenzoate, 0.5 part of polyethylene glycol, 0.5 part of glutathione, and 40 parts of normal saline into the container, stir and heat to 75 °C, Insulation standby;

[0082] (2) Put the above-mentioned raw materials and normal saline in a vacuum homogeneous emulsifier, control the sp...

Abstract

The invention relates to the technical field of cosmetics, particularly a silkworm pupa polypeptide day cream which comprises 10-25 parts of silkworm pupa protein or silkworm pupa protein polypeptide, 1-6 parts of sambucus extract, 1-6 parts of peanut skin, 1-6 parts of grape skin extract, 1-2 parts of rice bran oil, 1-4 parts of humectant, 1-3 parts of azone and 0.1-0.5 part of glutathione. The combination of the active silkworm pupa polypeptide other active substances in the silkworm pupa polypeptide day cream can better nourish the skin, effectively prevent and resist wrinkles from generation, enhance the skin elasticity and postpone aging. The day cream 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 day cream provided by the invention has better effects than common day creams.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a silkworm chrysalis polypeptide day cream, and also relates to a preparation method of the silkworm chrysalis polypeptide day cream. Background technique [0002] 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. Studies have confirmed that silkworm chrysalis protein and its enzymatic hydrolysis product silkworm chrysalis active polypeptide have strong antioxidant activity and free radica...
