Stearic acid is a saturated fatty acid that occurs naturally in various animal and plant fats. It’s used as a thickening agent in skincare products like creams, lotions and cleansers. Stearic acid also contributes to the texture, consistency and stability of skincare products to help improve application and overall performance.
Stearic acid can be derived from various sources like animal fats and plant oils or created from other fatty acids.
Stearic acid is generally well-tolerated on most skin when used at appropriate concentrations.
Prevents Product Separation
Stearic acid blends oil and water-based ingredients to prevent separation for a consistent application.
Improves Product Texture
Stearic acid helps skincare products feel smoother and creamier and improves the overall application experience.
While stearic acid itself is not a moisture ingredient, its presence in formulas can lock in moisture and create a protective barrier on skin.
Protects against Environmental Damage
In certain formulas, stearic acid can provide a protective barrier on skin's surface to help shield skin from environmental pollutants and harsh weather conditions.
