Problems solved by technology

[0004] The technical problem to be solved by the present invention: In view of the fact that most of the current whitening cream products add arbutin as the whitening active ingredient, although it plays a role in skin lightening, it is unstable and easy to decompose. , remove the pigment in it, and then decompose the cellulose in it by enzymatic hydrolysis, retain the unique essential oil, pectin and effective substances that inhibit tyrosinase, and then ferment it through lactic acid bacteria, decompose egg white to increase amino acids, and decompose fresh mulberry Add effective substances that inhibit tyrosinase on the inner surface of the skin, and at the same time obtain bactericidal and antibacterial substances. Finally, add sodium hyaluronate to promote the skin’s absorption of whitening cream and supplement amino acids to the skin. Essential oils form a unique protection for the skin to prepare an antioxidant whitening cream

Abstract

The invention relates to a method for preparing anti-oxidant whitening cream from citrus peel and belongs to the technical field of cosmetics. Oriented to the problems that in the prior art, arbutin is added in most whitening cream products to serve as a whitening active ingredient and is unstable and prone to decomposition although the skin brightening effect is achieved, the method comprises the steps that firstly, citrus peel is treated to remove pigment in the citrus peel, then cellulose in the citrus peel is decomposed through enzymolysis, and special essential oil, pectin and the effective substance for suppressing tyrosinase in the citrus peel are preserved; then, the citrus peel is fermented with lactobacillus, egg white is decomposed to increase amino acid, the inner surface of fresh mulberry bark is decomposed to increase the effective substance for suppressing tyrosinase, and meanwhile bacterium killing and suppressing substances are obtained; finally, sodium hyaluronate is added to promote absorption of the skin to the whitening cream and supplementation of amino acid to the skin, special protection on the skin is formed through special essential oil in the citrus peel, and thus the anti-oxidant whitening cream is obtained.

Description

technical field [0001] The invention relates to a method for preparing an antioxidant whitening cream by using citrus peels, which belongs to the technical field of cosmetics. Background technique [0002] Skin pigmentation can be divided into chloasma, pregnancy spot, butterfly spot, age spot, coffee spot and freckle according to the type, and is a common multiple skin disease. The main causes of skin pigmentation are endocrine disorders, weakened metabolism, dry skin, aging, sun exposure, ultraviolet radiation, lack of sleep, physical fatigue and so on. With the growth of age, the number of spots increases, which seriously affects people's facial beauty, brings the psychological pressure of aging, and thus affects the quality of life. [0003] As we all know, skin color is mainly determined by the content of melanin in the skin, and melanin can protect the body from ultraviolet rays, and melanin is synthesized by melanocytes. The biochemical reaction process in melanocyt...
