Usage

General Description

2,4-Diaminophenoxyethanol is a chemical compound that is commonly used in hair dyes and cosmetics. It is an organic compound with the chemical formula C8H12N2O2. This chemical is used as a hair dye ingredient because of its ability to color the hair and provide long-lasting results. It is also used in some cosmetic products due to its properties as a hair reconditioning agent. However, 2,4-Diaminophenoxyethanol has been associated with skin irritations and allergies in some individuals, so it is important to use products containing this chemical with caution and to avoid contact with sensitive skin.
