Stigmasterol

Product Description

Stigmasterol is a high-purity, essential plant sterol, forming a critical part of the natural phytosterol complex vital for skin health. It works in concert with Beta-Sitosterol and Campesterol to create a biomimetic lipid structure within the stratum corneum. Its key advantage is completing this "phytosterol trio," ensuring a comprehensive approach to vegan barrier repair that closely mimics the skin's own cholesterol function. Additionally, Stigmasterol offers valuable skin conditioning and soothing properties. For formulators aiming to build the most effective, plant-based barrier restoration systems, Stigmasterol is an indispensable component.

Product Uses

This essential phytosterol is ideal for comprehensive barrier repair and soothing formulations:

• • Barrier Repair: Used synergistically with Beta-Sitosterol and Campesterol in creams, lotions, and balms to create a complete, high-performance plant sterol blend.
  • Soothing Formulations: Contributes to the overall calming effect in products for sensitive or reactive skin.
  • Mature Skin Care: Helps replenish the lipid matrix and supports skin resilience in anti-aging products.

* Vegan Formulations: An essential building block for brands seeking effective, plant-based alternatives to animal-derived cholesterol.

Formulation Suggestions

The recommended dosage is typically 0.1-1.0%, often used as part of a phytosterol blend. Stigmasterol is a high-melting-point (approx. 165-170°C) crystalline powder. It must be added to the oil phase and heated significantly until fully dissolved, ideally alongside other high-melting lipids like Beta-Sitosterol or waxes. Ensure complete dissolution before emulsification. Controlled cooling is crucial to minimize potential recrystallization. The combination with other key barrier lipids enhances its efficacy.
