4-METHYLBENZYL 4,5-DIAMINO PYRAZOLE SULFATE

Description

4-Methylbenzyl 4,5-diamino pyrazole sulfate is a synthetic hair dye ingredient primarily used in permanent and semi-permanent hair coloring products. This compound belongs to the class of pyrazole derivatives, known for their ability to produce vibrant and long-lasting hair color results. The molecule consists of a pyrazole ring with two amino groups at positions 4 and 5, coupled with a 4-methylbenzyl group and a sulfate ion.

In hair dye formulations, this ingredient functions as a color precursor, reacting with oxidizing agents like hydrogen peroxide to form larger, colored molecules within the hair shaft. The presence of the amino groups enhances its ability to penetrate the hair cuticle and bind to the cortex, resulting in durable color. The 4-methylbenzyl group contributes to the specific shade and intensity of the final color.

When used in combination with other dye precursors and coupling agents, 4-methylbenzyl 4,5-diamino pyrazole sulfate can produce a wide range of hair colors, particularly in the warm brown to red spectrum. It is generally considered safe for use in hair dye products when applied according to manufacturer instructions and regulatory guidelines.
