HC Blue no 2
Harm score: 4 (Slightly harmful chemistry)
HC Blue no 2, also known as zinc lactate, is a chemical compound that is often used in the cosmetic industry. It is an organic complex of zinc and lactic acid. It is usually available in the form of a white, solid powder. It is insoluble in water and alcohol, but soluble in a solution of mineralized acetic acid. Since it is a combination of zinc, which is an essential element needed for the proper function of certain enzymes and the growth of body cells, HC Blue no 2 is an important component of some health and beauty care products.
Zinc lactate is mainly used in cosmetics for its antiseptic and antibacterial properties. Due to these properties, it is often found in skin care products such as cleansing tonics, face masks and anti-acne creams. Its ability to regulate sebum production also makes it a popular ingredient in cosmetic products for problematic, oily or combination skin. In addition to skin care, HC Blue no 2 is also used in the hair care product line, where it plays the role of a conditioner and hair strengthener. Another application is in toothpastes and mouthwashes, where it acts as a preventative against tooth decay and gingivitis. Zinc lactate is also included in some antiperspirants and deodorants as it prevents the growth of bacteria that cause unpleasant odours. It is therefore a substance with a very wide range of uses.
