Trideceth-6 Phosphate ●
TL;DR. This ingredient functions mainly as an anionic surfactant and emulsifier, helping disperse oils, pigments, and other hydrophobic materials in water-based formulas. It can also improve wetting and formula stability in cleansing, color, and treatment products.
What does Trideceth-6 Phosphate do in a cosmetic formula?
This ingredient functions mainly as an anionic surfactant and emulsifier, helping disperse oils, pigments, and other hydrophobic materials in water-based formulas. It can also improve wetting and formula stability in cleansing, color, and treatment products.
Is Trideceth-6 Phosphate clean?
Clean standards often flag it because ethoxylated materials can carry trace ethylene oxide or 1,4-dioxane if purification is poor. In finished formulas, the main user-facing issue is eye or skin irritation potential typical of anionic surfactants, especially at higher concentrations.
Is Trideceth-6 Phosphate sustainable?
This material is commonly made from fatty alcohol feedstocks combined with petrochemical ethoxylation chemistry, so its sourcing profile is mixed. It is expected to have some biodegradability as a surfactant, but the it content and manufacturing route create more environmental friction than simpler plant-derived emulsifiers.
Is Trideceth-6 Phosphate COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic because ethoxylation is not aligned with those standards. From a Green Chemistry lens, it has useful low-dose functionality but scores lower for petrochemical inputs, possible processing residues, and wastewater nutrient considerations.
How does Trideceth-6 Phosphate work chemically?
The molecule is an anionic it ester built from a C13 fatty alcohol ethoxylate with about six ethylene oxide units, giving it both oil affinity and water dispersibility. It is typically used at low single-digit percentages, performs best when the acidic groups are neutralized, and can be paired with nonionic or amphoteric surfactants to improve solubilization and wetting.
