Hydroxystearic Acid: The Versatile Fatty Acid for Skin and Cosmetic Formulations

What is Hydroxystearic Acid?

Hydroxystearic Acid is a hydroxy fatty acid derived from stearic acid, a naturally occurring saturated fatty acid found in animal and plant fats. The presence of a hydroxyl (-OH) group in its structure gives it unique chemical properties that make it valuable in cosmetics and personal care formulations.

It is often used as an emulsifier, thickening agent, and emollient, contributing to the texture, stability, and moisturizing qualities of skincare and makeup products.

Key Benefits of Hydroxystearic Acid

1. Enhances Emulsion Stability

Hydroxystearic Acid helps bind oil and water phases together, improving the stability of creams and lotions and preventing separation over time.

2. Provides Thickening and Texture

It increases the viscosity of formulations, creating a rich, creamy texture that feels luxurious on the skin.

3. Moisturizing Emollient

Its fatty acid nature enables it to form a protective barrier on the skin, reducing water loss and leaving skin feeling soft and smooth.

4. Improves Spreadability

Hydroxystearic Acid enhances the spreadability of creams and lotions, allowing for even application and better absorption.

5. Versatile Ingredient

It is compatible with various other cosmetic ingredients, making it useful in everything from moisturizers and sunscreens to lipsticks and makeup foundations.

Common Uses in Personal Care Products

• Moisturizers and body lotions

• Sunscreens and after-sun care

• Lipsticks and lip balms

Environmental and Natural Origin

Derived from natural fats and oils, Hydroxystearic Acid aligns well with the trend toward natural and sustainable beauty products. Its biodegradable nature makes it environmentally friendly when sourced responsibly.

Final Thoughts

Hydroxystearic Acid is a multifunctional fatty acid that plays an important role in enhancing the texture, stability, and moisturizing benefits of personal care formulations.
