CRITICAL WARNINGS
-
Lipophilic Emulsifier: Stearyl palmityl tartrate is a highly lipophilic emulsifier with very low HLB value (~2-4), making it suitable for water-in-oil (W/O) emulsions.
-
Sauce and Dressing Stabilizer: Widely used in sauces and dressings to improve emulsion stability and prevent separation. Provides viscosity and body to products.
-
Food Emulsifier (E483): Approved in the EU as E483. However, some countries have restrictions or bans on its use. Always check local regulations.
-
Not Approved in USA: E483 is not approved by the FDA and is not on the GRAS list. Not permitted for food use in the United States.
-
Low Dosage: Effective at very low concentrations (0.1-0.5%), providing cost-effective stabilization.
-
Waxy Solid: Solid at room temperature. Must be melted (60-70°C) before use in formulations.
-
Heat Stability: Stable at high temperatures; suitable for heat-processed products.
-
Hydrolysis: Hydrolyzes to tartaric acid and fatty alcohols (stearyl, palmityl) under extreme conditions.
-
Crystallization Control: Controls fat crystallization, improving texture and shelf life of products.
-
Regulatory Variations: While approved in the EU (E483), it is not permitted in the USA and some other countries. Always verify local regulations before use.
