Abstract

The invention discloses a double-agent hair dyeing composition which comprises a first agent and a second agent. The first agent comprises, by weight, 30-70% of liquid grease, 1-7% of water-soluble emulsion thickener and 0.01-2% of antioxidant; the second agent comprises, by weight, 3-12% of hydrogen peroxide, 20-60% of liquid grease and 1-7% of water-soluble emulsion thickener. A specific amountof liquid grease and water-soluble emulsion thickener are added into the first agent, and a specific amount of liquid grease and water-soluble emulsion thickener are added into the second agent, so that the prepared double-agent hair dyeing composition is excellent in high-and-low temperature stability. The preparation process of the double-agent hair dyeing composition is simple and low in energyconsumption.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a two-component hair dye composition and a preparation method thereof. Background technique [0002] Hair dyes usually develop color by mixing the first agent and the second agent, so that the dye intermediates in the first agent undergo oxidative polymerization. At the same time, the hydrogen peroxide in the second dose decomposes the melanin in the hair to decolorize the hair, lighten the base color, and then dye various colors. The molecular weight of the dye intermediate is relatively small, so it can penetrate into the fur cortex, and after oxidative polymerization, the resulting product is retained in the cortex and is not easily washed off by shampoo. [0003] It is also known that, in order to allow the dye intermediate to penetrate into the cortex layer more effectively, usually an alkaline agent, such as ammonia water, is added to the dye cream to swell the hair keratin.
