Whitening lotion and preparation method thereof

Abstract

The invention discloses a whitening lotion and a preparation method thereof. The whitening lotion is prepared from a whitening composition, the whitening composition is prepared from the following whitening components in parts by mass: 4 to 7 parts of nicotinamide, 0.01 to 0.5 part of nonapeptide-1 solution, 0.5 to 1 part of carnosine, 0.3 to 1 part of glycyrrhiza glabra root extract, 0.03 to 0.1part of citrus peel extract and 0.5 to 2 parts of ascorbyl glucoside, the preparation method of the whitening lotion is simple; on one hand, generation and transfer of melanin are inhibited from multiple angles, on the other hand, components such as the citrus peel extract are added to further improve skin brightness, improve skin quality and improve skin color, the whitening effect of the productis remarkably improved through the synergistic effect of the multiple components, and a new whitening skincare product choice is provided for consumers.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and relates to a whitening milk and a preparation method thereof. Background technique [0002] Melanin is mainly produced by melanocytes in the basal layer of the human skin. The irradiation of ultraviolet rays will change the melanin to produce a substance that protects the skin, and then the melanin moves through the layers of cell metabolism to the epidermis of the skin, forming skin problems such as spots and uneven skin tone that we see. Recognized intracellular synthesis pathway of melanin: tyrosine is oxidized to dopaquinone, and then oxidized and decarboxylated to form dioxindole, which is then transformed into melanin, which is the main component of skin pigment; another side branch, that is, dopaquinone through valley Glutathione or cysteine ​​catalyzes the formation of pheomelanin. [0003] For many years people have been targeting the key rate-limiting enzyme in the production of mel...

AI Technical Summary

Problems solved by technology

However, the whitening ingredients targeting tyrosinase activity need to penetrate the stratum corneum and play a role in the epidermis, and the active substances are simply added to the formula, which is difficult to penetrate, and even accumulate on the skin surface to have a negative effect on the skin; This single mechanism of inhibition coupled with suboptimal penetration of actives makes these skin lightening products less effective

[0004] In addition, as people's understanding of melanin continues to deepen, it is not comprehensive enough to develop whitening products based solely on the inhibition of tyrosinase activity.
