Problems solved by technology

[0003] The molecular structure of whitening agents often contains chemically reactive functional groups (such as hydroxyl, carbonyl, carbon-carbon double bonds, etc.). If there is no antioxidant in the whitening essence, the whitening essence will easily oxidize and turn yellow at room temperature, and the whitening effect will be weakened.

Abstract

The invention belongs to the field of cosmetics, and discloses a whitening essence suitable for long-term storage, which comprises a whitening component and an antioxidant component, wherein the whitening component comprises the following components in percentage of the total weight of the whitening essence: 0.5-5% of nicotinamide; 0.5-3% of a bifida ferment lysate; and 0.01 to 0.1% of adenosine; the antioxidant component comprises the following components in percentage of the total weight of the whitening essence: 0.1-0.5% of tocopheryl acetate, 0.2 to 1% of p-hydroxyacetophenone; 0.01 to 0.1% of tris(tetramethylhydroxypiperidinol) citrate; and 0.1 to 2% of ascorbyl tetraisopalmitate. The whitening essence can still be used for whitening effectively after being stored for a long time. Meanwhile, the invention further provides a preparation method of the whitening essence.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a whitening essence suitable for long-term storage and a preparation method thereof. Background technique [0002] At present, there are more than 90 kinds of whitening and anti-freckle raw materials allowed in cosmetics in my country, including niacinamide, arbutin, root extract of glabra (glycyrrhiza glabra), phenylethyl resorcinol, and tranexamic acid. [0003] The molecular structure of whitening agents often contains chemically reactive functional groups (such as hydroxyl, carbonyl, carbon-carbon double bonds, etc.). If there is no antioxidant in the whitening essence, the whitening essence will easily oxidize and turn yellow at room temperature, and the whitening effect will be weakened. . [0004] Some formulators will add classic antioxidants (such as butylated hydroxytoluene, butylated hydroxyanisole or tert-butyl hydroquinone) to the formula to make the product obt...
