What Is Zinc Phenol Sulfonate?
Zinc phenol sulfonate is an organic compound formed by bonding a sulfo group (-SO3H) to a phenol, resulting in a zinc salt. Although not specifically regulated by domestic laws, its use in cosmetics is limited to certain concentrations.
Uses of Zinc Phenol Sulfonate
Primarily used in cosmetics, zinc phenol sulfonate serves as an active ingredient in antiperspirants and deodorants, particularly targeting sebum odor. It operates by suppressing sweat and sebum secretion and inhibiting bacterial growth, thereby preventing both sweat and sebum odor effectively.
Properties of Zinc Phenol Sulfonate
This compound exhibits astringent properties, helping to tighten pores and reduce sebum secretion, which can also aid in acne prevention. While it might offer lower antiperspirant power compared to ingredients like aluminum chloride, it is considered safer for use.
Structure of Zinc Phenol Sulfonate
Its molecular structure includes a benzene ring bonded to one hydroxy group (-OH) and a sulfo group (-SO3H), forming a zinc salt (-SO3)2Zn. Zinc phenol sulfonate commonly exists in several types, with zinc p-phenolsulfonate being the most utilized variant.
