preparation example Construction

[0044] The present invention also provides a preparation method of a phycocyanin protective agent, comprising the step of mixing glycerin, butanediol, sodium chloride and sodium benzoate.

[0045] The present invention also provides a phycocyanin composition, comprising the phycocyanin protective agent of the present invention and phycocyanin, the weight ratio of the phycocyanin protective agent to phycocyanin is 10-30:0.01, preferably 15 -25:0.01;

[0046] Preferably, the phycocyanin is derived from one or a combination of two or more of Spirulina bonate, Spirulina platensis and A. water blooms.

[0047] The phycocyanin composition of the present invention can be applied in cosmetics. The cosmetics may include water-based cosmetics, emulsion-based cosmetics, and cream-based cosmetics; preferably water-based cosmetics.

[0048] Wherein, the water-based cosmetics include: lotion or cleansing water; the emulsion-based cosmetics include: moisturizing lotion, skin care essence, ...

Embodiment 1

[0067] Dissolve 0.1g of phycocyanin in 1000g of water to form a 100ppm aqueous solution of phycocyanin, and measure its absorbance A 0 . Add 12g glycerol, 9g butanediol, 3g sodium chloride and 0.15g sodium benzoate successively in reactor, wherein, the weight ratio of glycerol, butanediol, sodium chloride and sodium benzoate is 80:60:20:1. Then add the prepared phycocyanin aqueous solution to 150 g to obtain the aqueous solution of phycocyanin composition I. Measure the absorbance A of the aqueous solution of phycocyanin composition I at 620nm (620nm is the characteristic absorption peak of phycocyanin, the same below) 1 , as shown in Table 1 below. Then the aqueous solution of phycocyanin composition I was evenly divided into 3 PET bottles, and placed in the environment of room temperature avoiding light, room temperature light, and 40°C constant temperature and light avoiding respectively, and the aqueous solution of phycocyanin composition I was measured respectively afte...

Abstract

The invention provides a phycocyanin protective agent and a preparation method thereof, a phycocyanin composition and a moisturizing lotion. The phycocyanin protective agent is prepared from the following components: glycerin, butanediol, sodium chloride and sodium benzoate. The phycocyanin protective agent provided the invention has the advantages that on one hand, protein aggregation can be prevented so as to reduce the deposition of the phycocyanin in a solution; on the other hand, bacterial growth can be effectively inhibited so that the phycocyanin can keep the original bright blue color in the solution.

Description

technical field [0001] The invention relates to a phycocyanin protective agent, a preparation method thereof, a phycocyanin composition and a moisturizing lotion, and belongs to the field of cosmetics. Background technique [0002] Phycocyanin is a dark blue powder isolated from spirulina, mainly found in cyanobacteria, red algae and cryptophyta. Phycocyanin is one of the rare pigment proteins in nature. It is a porphyrin-like pigment protein in cyanobacteria. It is composed of a carrier protein and a chromophore-an open-chain linearly extended tetrapyrrole compound. It is bright in color, soluble in water, and insoluble in alcohols and fats. [0003] Phycocyanin can be used as an additive in cosmetics. It is a very rich protein with a complete amino acid composition, and the essential amino acids account for 37.2% of the total. Studies have shown that phycocyanin has good effects in anti-oxidation, anti-virus, anti-inflammation, anti-radiation, lowering blood fat and enh...
