PEG-5 SOYAMINE.

Optional CAS 61791-24-0 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-5 Soyamine is an ethoxylated soybean-derived fatty amine, primarily utilized in formulations as an effective surfactant and emulsifier. It facilitates the harmonious blending of disparate liquid phases and contributes to formula stability.

Science

Mechanism of Action

As a versatile PEG derivative, PEG-5 Soyamine primarily operates as a surfactant, lowering surface tension to allow for the effective mixing of oil and water components. It also acts as an emulsifier, stabilizing these mixed phases. Beyond these primary functions, it can serve as a mild detergent, a foam booster, and an antistatic agent. Furthermore, akin to other PEGs, it may impart emollient properties, contributing to skin softening and lubrication, and can enhance moisture retention by forming hydrogen bonds with water molecules, thereby reducing transepidermal water loss. Its potential as a delivery vehicle could improve the penetration of other active ingredients.

Stability

While specific pH ranges are not precisely detailed for PEG-5 Soyamine, related ethoxylated fatty amines demonstrate broad pH stability, being efficient in both acid and alkaline formulations due to their combined nonionic and cationic surfactant action.

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEG-5 Soyamine safe for use in cosmetic formulations, provided it is formulated to be non-irritating and concentrations do not exceed 4% (as reported in hair coloring). Formulators must ensure the removal of potential 1,4-dioxane and unreacted ethylene oxide residues. A critical caution advises against its use on damaged or compromised skin due to observed systemic toxicity and sensitization risks under such conditions.

Verdict

Optional

PEG-5 Soyamine is a functional ingredient primarily valued for its surfactant and emulsifying properties in cosmetic formulations, with potential for emollience and moisture retention, though direct skin efficacy data remains limited and its use requires careful formulation to ensure safety, particularly on compromised skin.
