Abstract

The invention discloses a slow-release lotion carrier for whitening and spot removing, and a preparation method thereof. The carrier is loaded with active ingredients of whitening and spot removing effect and is characterized in that the slow- release lotion carrier for whitening and spot removing comprises the following ingredients by weight percent: 0.5-1% of active ingredients, 0.05-1% of Vitamin E, 10-25 % of emollients, 15-30 % of surface active agents, 5-15% of moisturizers, 3-5 % of mesoporous silicon, 0.05-1% of pH regulators and the balance of deionized water. According to the invention, the slow- release lotion carrier for whitening and spot removing belongs to w/o structures; the mesoporous silicon has the characteristic that oxygen atoms on the structure of the mesoporous silicon are prone to form hydrogen bonds with hydrophilic ends of the amphipathic surface active agent, so as to form a layer of shell at the oil water interface and delay the release time of the active ingredients. The slow-release lotion for whitening and spot removing has excellent stability and the preparation method is simple, so that when the slow- release lotion carrier is applied to conventional whitening and spot removing cosmetics, the effects of the conventional cosmetics can be greatly improved and the slow- release lotion carrier has a broad market.

Description

technical field [0001] The invention relates to the technical field of carrier systems in the preparation technology of new cosmetics, relates to a slow-release milk carrier and a preparation method thereof, in particular to a slow-release milk with whitening and freckle-removing active ingredients and a preparation method thereof.
