Problems solved by technology

In this patent, the sericin solution prepared by dissolving sericin with soda ash is an alkaline solution with a pH of 10. Neutralization is not mentioned in the patent. Using such a raw material solution directly as a skin care product will have potential safety hazards. If it is applied to the skin After application, as the water evaporates, the alkaline components are highly concentrated and the skin will be damaged
In addition, it is difficult to guarantee the hygiene index and the purity of sericin prote

Embodiment Construction

[0033] Concrete formula is as follows in each embodiment of the present invention:

[0034]

[0035] The silk extract added in proportion to the above formula is silk peptide or silk fibroin or a mixture of silk peptide and silk fibroin. Within a certain range, the more silk extract is added, the better the sunscreen effect will be. However, increasing the proportion of silk extract will also cause problems in the overall stability and preservation of the emulsion, so the proportion of its addition needs to be considered comprehensively.

[0036] The preparation method of the present invention is:

[0037] 1) Mix C12-15 alcohol benzoate, isopropyl myristate, dioctyl carbonate, cyclomethicone, C12-20 alkyl glucoside, ethylparaben, hydroxyphenyl Heat the methyl ester to 80--85°C in an oil pan, and stir evenly;

[0038] 2) Add glycerin, panthenol, allantoin, disodium EDTA, and dehydroxanthan gum into deionized water according to the ratio, heat and dissolve, then pump into t...

Abstract

The invention relates to silk-extract-containing sunscreen skincare emulsion and a preparation method thereof. The emulsion is characterized by being prepared from the following raw materials at weight ratio: 51.3%-76.9% of deionized water, 0.1%-15.0% of silk extract, 6.0%-8.0% of C12-C15 alkyl benzoate, 4.5%-6.0% of glycerin, 4.0%-6.0% of isopropyl myristate, 2.5%-4.0% of dicaprylyl carbonate, 2.5%-3.0% of cyclic poly(dimethylsiloxane), 1.5%-3.0% of C12-20 alkyl glucoside, 0.4%-0.8% of methyl hydroxybenzoate, 0.4%-0.8% of ethyl hydroxybenzoate, 0.6%-0.8% of panthenol, 0.3%-0.5% of allantoin, 0.1%-0.3% of ethylenediaminetetraacetic acid (EDTA) disodium, 0.1%-0.3% of dehydroxanthan gum and 0.1%-0.2% of essence. The sunscreen skincare emulsion obtained by the method is used safely and effectively.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a silk extract sunscreen skin care milk and a preparation method thereof. Background technique [0002] The sunscreen ingredients of currently commercially available sunscreen skin care products are composed of chemical sunscreen agents and nano-scale inorganic metal oxide powders (such as titanium dioxide) sunscreen ingredients. The latest research shows that the use of these sunscreen ingredients is risky, and the greater the amount, the greater the risk. Facts have proved that chemical sunscreens usually cause allergic symptoms on sensitive skin and have obvious irritation on normal skin; nanoscale inorganic metal oxide powder sunscreen ingredients often block pores, affect the normal breathing and perspiration of the skin, and cause hair follicles to irritate. Inflammation, the possibility of exacerbation of symptoms is not excluded. [0003] The patent number is 200910101...
