Stearic Acid (Hystric) is a saturated fatty acid widely used as a functional ingredient in cosmetic and manufacturing applications. It is valued for its ability to contribute body, thickness, and structure to various formulations.
In skincare products, Stearic Acid is used in creams, lotions, body butters, and other emulsified systems to help create a rich, smooth consistency. When combined with suitable emulsifiers and other ingredients, it can help support the structure of oil-in-water emulsions.
Stearic Acid is also used in soap manufacturing, where it can contribute hardness and texture to soap bars. In selected candle formulations, it may be used as a formulation additive to modify firmness and other physical characteristics, provided the grade is suitable for candle-making applications.
The performance of Stearic Acid (Hystric) depends on its purity, fatty acid profile, grade, and formulation conditions. Always consult the supplier’s technical data sheet before selecting the material for a particular application.
