Diethanolamine bisulfate is a chemical compound, the diethanolamine salt of sulfuric acid. Diethanolamine (DEA) is a chemical compound, a water-soluble molecule obtained by the extraction of ethylene oxide with ammonia. DEA shows reactive capacity is an aminoalcohol as it combines the properties of alcohols and amines.

Cosmetics

Buffering agent. An ingredient that can bring an alkaline or acid solution to a certain pH level and prevent it from changing. in practice a pH stabiliser.

pH adjuster. This ingredient tends to restore the pH of a cosmetic formulation to its optimal value. The correct pH value is an essential determinant for lipid synthesis in the stratum corneum. The average physiological pH value of the face ranges between 5.67 and 5.76. The hair fibre has a pH value of 3.67.
