Science
Mechanism of Action
This ingredient operates by significantly reducing the surface tension between immiscible liquids, such as oil and water. Its unique molecular architecture possesses both lipophilic (oil-attracting) and hydrophilic (water-attracting) components, enabling it to bridge and stabilize these otherwise incompatible phases. As an emulsifier, it is critical for forming and maintaining stable oil-in-water emulsions, preventing product separation. As a surfactant, it improves the wetting properties of a liquid, facilitating the dispersion and removal of impurities from the skin.

Ingredients within the Phosphoric Acid, (ethoxylated tridecyl alcohol) Esters class, which includes TRIDECETH-3 PHOSPHATE, demonstrate typical stability under standard formulation conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Trideceth ingredients, including TRIDECETH-3 PHOSPHATE, are safe for use in cosmetics when formulated to ensure they are non-irritating. A critical consideration involves the potential presence of trace toxic impurities like Ethylene Oxide and 1,4-Dioxane, which are by-products of the ethoxylation process. However, responsible manufacturers can effectively control and remove these contaminants through stringent purification processes. The FDA also permits Trideceth ingredients as indirect food additives, and EWG's Skin Deep rates it with low concerns regarding cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.
