Sorbitan Tristearate

Sorbitan Tristearate is an emulsifier made from sorbitan, a compound derived from sorbitol, and stearic acid, a fatty acid. It helps improve the consistency and stability of formulations containing oil-based ingredients.

It is commonly used in cosmetics and personal care products, including creams, lotions and makeup. It is also identified as a food emulsifier (INS 492 / E492), where its use is permitted under applicable food regulations.

Sorbitan Tristearate is generally considered to have a low safety concern when used appropriately in cosmetic formulations. However, scientific safety assessments and regulatory permissions are different: the fact that an ingredient has been assessed for safety does not automatically mean it is permitted for every use in every country.

Regulatory note: FSSAI lists Sorbitan Tristearate (INS 492) as an emulsifier, but its permitted use must be checked against the applicable food category and conditions of use. In the United States, the FDA lists Sorbitan Tristearate for specified indirect food-contact uses; this should not be interpreted as blanket approval for direct addition to food.

Manufacturers use Sorbitan Tristearate mainly to improve the texture, consistency and stability of products.

• In cosmetics: It helps oil-based ingredients disperse more evenly and contributes to a smooth, consistent texture in creams, lotions and makeup.
• In food: Where specifically permitted, it functions as an emulsifier, helping improve the consistency and uniformity of certain food products.
• For product stability: It helps maintain a consistent formulation and can reduce ingredient separation in suitable products.

Are there any safety concerns? Sorbitan Tristearate is not generally considered a major safety concern when appropriately used in cosmetic formulations. However, individual skin reactions are possible, and food safety depends on exposure, the intended use and applicable regulations.

Important for consumers: The presence of Sorbitan Tristearate alone does not mean a product is harmful. For food products, its regulatory status should be verified for the relevant food category and country rather than inferred from its INS or E-number alone.
