PEG-15 TALLOW AMINOPROPYLAMINE.

Valuable CAS 61790-85-0 / SURFACTANT - EMULSIFYING

PEG-15 TALLOW AMINOPROPYLAMINE is a versatile ingredient functioning primarily as a surfactant, emulsifier, and antistatic agent in cosmetic formulations. It facilitates the stable blending of oil and water phases, essential for uniform product texture and performance.

Science

Mechanism of Action

This ingredient operates by reducing the interfacial tension between incompatible substances like oil and water, thus enabling the creation of stable emulsions. As an antistatic agent, it neutralizes electrostatic charges, particularly beneficial in hair care products. Polyethylene glycols (PEGs) generally contribute to product viscosity, solubility, and can act as consistency enhancers or humectants.

Stability

A 5% aqueous solution of Tallow Amine 15 EO (a synonym) exhibits a pH range of 8.0–10.5. While largely non-ionic, it may show slight pH-dependent interactions. Degradation of its polyether chains can occur with prolonged exposure to strong acids or bases. Its water solubility increases with higher ethylene oxide content, and it is also soluble in alcohols and polar organic solvents.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Max tested
3%
Sensitization risk Moderate

The CIR Expert Panel deems PEG-15 TALLOW AMINOPROPYLAMINE safe for cosmetic use when formulated to be non-irritating. The highest reported maximum use concentration for leave-on dermal exposure is 3% in products like body and hand sprays. Concentrated forms, however, can be highly irritating to skin, corrosive to eyes, and sensitizing, though dilution significantly reduces this potential. Formulators must address concerns regarding potential contamination with toxic impurities such as ethylene oxide and 1,4-dioxane. 'Peg tallow amine' is listed in the FDA's Inventory of Food Contact Substances, and a synonym is listed by the EPA as a pesticide inert ingredient.

Verdict

Valuable

PEG-15 TALLOW AMINOPROPYLAMINE is a valuable formulation aid, crucial for emulsion stability and antistatic properties, but requires careful dilution and formulation to meet CIR safety restrictions and mitigate impurity risks.
