Moisturizing and skin tendering essence and preparation method thereof

Abstract

The invention provides moisturizing and skin tendering essence. The moisturizing and skin tendering essence comprises, by weight, 1-100 parts of recombinant fibroin, 1-100 parts of a radix paeoniae alba extract, 1-100 parts of a rhizoma bletillae extract, 1-100 parts of a herba portulacae extract, 1-100 parts of a honeysuckle flower extract, 1-100 parts of a tangerine fruit extract, 1-100 parts of a red clover extract, 1-100 parts of a papaya fruit extract, 1-100 parts of a royal jelly extract and 1-100 parts of a wheat germ extract. The moisturizing and skin tendering essence has excellent moisturizing, moistening, skin tendering, anti-wrinkle, whitening and anti-allergic effects, and can prevent external irritation to the skin and consolidate the curative effect. The invention also provides a preparation method of the moisturizing and skin tendering essence. The moisturizing and skin tendering essence can play a drug effect to the greatest extent, and the moisturizing, skin-tendering and anti-aging curative effects are improved.

Description

technical field

[0001] The invention relates to the technical field of skin care products, in particular to a moisturizing and skin rejuvenating essence lotion and a preparation method thereof. Background technique

[0002] The skin plays an important barrier function in the human body, which protects the body from external factors such as ultraviolet rays and dry environments, and prevents excess water from being lost from the body through the skin. This protective function is maintained when the keratinocyte-containing stratum corneum is maintained in a normal state. The barrier function of the skin mainly includes the physical, chemical, biological and moisture permeability functions. The normal skin moisture content is 20%-35%. When the skin moisture content drops below 10%, the barrier function is damaged. Decreased skin barrier function will lead to many skin diseases such as pruritus, atopic dermatitis, dull and dull skin, spots, psoriasis, acne and dry skin. [000...

Examples

preparation example Construction

[0047] A preparation method of the above-mentioned moisturizing and skin rejuvenating essence, comprising the following steps:

[0048] S1: At the gene level, the fibroin gene sequence was optimized using the Pichia pastoris customary codons and artificially synthesized, and integrated into the yeast chromosome to construct a constitutively expressed recombinant Pichia pastoris engineering strain, which was transferred to the fermentation medium Finally, the recombinant fibroin is actively secreted and expressed in the fermentation broth along with the life activities of the engineered bacteria, and the supernatant is collected by centrifugation. For fibroin, the eluate was collected, desalted, concentrated, and finally recombined fibroin was obtained by vacuum freeze-drying for subsequent use;

[0049] S2: Grinding Radix Paeoniae Alba, Radish Radish, Purslane, Honeysuckle, Citrus, Red Trifolium, Papaya, Royal Jelly, and Wheat Germ, sieving, and then adding 10-20 times the wei...

Embodiment 1

[0069] A moisturizing and rejuvenating essence lotion, comprising: 40 parts by weight of recombinant fibroin, 12 parts of white peony extract, 15 parts of white root extract, 10 parts of purslane extract, and 11 parts of honeysuckle flower extract 15 parts of citrus fruit extract, 8 parts of red clover extract, 10 parts of papaya fruit extract, 15 parts of royal jelly extract, 20 parts of wheat germ extract, 400 parts of solvent, 3 parts of thickener, 30 parts of moisturizer, 20 parts of skin conditioner, 6 parts of surfactant, 10 parts of chelating agent, 3 parts of emollient, 3 parts of film former, 3 parts of preservative, and 3 parts of pH regulator.
