CALCIUM SULFATE HYDRATE

Description

Calcium Sulfate Hydrate, also known as gypsum, is a naturally occurring mineral compound with diverse applications in skincare formulations. This versatile ingredient is recognized for its absorbent properties and ability to enhance product texture. In cosmetic preparations, it functions primarily as a bulking agent and opacifier, contributing to the overall consistency and appearance of various skincare products.

The compound's water-binding capacity allows it to act as a mild desiccant, helping to control moisture levels in formulations and on the skin's surface. This property can be particularly beneficial in products designed for oily or acne-prone skin types. Calcium Sulfate Hydrate also serves as a gentle exfoliant, aiding in the removal of dead skin cells and promoting a smoother complexion.

In addition to its functional roles, this ingredient has been shown to have mild astringent properties, which can help temporarily tighten pores and reduce excess oil production. Its use in skincare formulations is generally well-tolerated, with a low risk of irritation or allergic reactions. However, as with any cosmetic ingredient, individual sensitivities may vary, and patch testing is recommended for those with particularly reactive skin.
