Abstract

The invention provides a composition for increasing skin glossiness and / or improving skin brightness and / or increasing skin whiteness. The composition comprises 0.01 to 6 wt% of lactobionic acid, 0.01 to 6 wt% of chitosan, and a cosmetically acceptable carrier. The invention also relates to an application of the composition in a skin external preparation and a method for increasing skin glossiness and / or improving skin brightness and / or increasing skin whiteness.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a composition containing lactobionic acid and its preparation and application. Background technique [0002] Lactobionic acid (4-o-b-d-galactopyranosyl-d-gluconic acid) is a new polyhydroxy biomimetic acid ingredient introduced into the field of skin care. Lactobionic acid is formed from the oxidation of the disaccharide lactose (lactose) and is currently used in the pharmaceutical industry as a salt form of intravenous erythromycin and in mineral supplements. However, its greatest commercial use is as a major component of organ preservation solutions during transplantation. This is due to its ability to inhibit tissue damage caused by oxygen free radicals during organ storage and subsequent reperfusion, enabling organs to be preserved outside the body for up to two days. [0003] Lactobionic acid is a hygroscopic compound that firmly binds atmospheric water and evaporates ...
