PEG-15 JOJOBA ACID.

Valuable / SURFACTANT - EMULSIFYING

PEG-15 Jojoba Acid is a precision emulsifying surfactant derived from jojoba oil, critical for blending oil and water phases in cosmetic formulations. Beyond its primary role, it also offers humectant and solubilizing properties, enhancing product texture and ingredient delivery.

Science

Mechanism of Action

PEG-15 Jojoba Acid operates as an emulsifying surfactant, leveraging its molecular architecture which integrates both hydrophilic (water-attracting PEG) and lipophilic (oil-attracting Jojoba Acid) segments. This enables it to reduce the interfacial tension between immiscible liquids, facilitating the stable formation of finely dispersed emulsions. As a polyethelene glycol derivative, it additionally functions as a humectant to attract and retain moisture, a solvent for various compounds, and potentially as a delivery system to enhance the penetration of other active ingredients into the skin.

Stability

This ingredient significantly contributes to the stability of both oil-in-water and water-in-oil emulsions. Related Jojoba Esters exhibit good oxidative stability, typically around 35 OSI hours, which can be further augmented by the inclusion of natural antioxidants like Tocopherol to extend product shelf life.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that a broad spectrum of 130 chemically related PEGylated oils, including PEG-15 Jojoba Acid, are safe for cosmetic application when precisely formulated to be non-irritating. While generally not sensitizing to normal, intact skin, PEGs can be readily absorbed through damaged skin and have been associated with contact dermatitis in cases such as burn patients. Significant concerns exist regarding potential contamination from impurities like ethylene oxide and 1,4-dioxane, particularly for related PEG-Jojoba Acid ingredients. Manufacturers are advised to stringently manage purity and ensure the non-irritancy of formulations. The FDA mandates cosmetic product safety but does not pre-approve ingredients; no specific SCCS opinion was available for this ingredient.
