PEG-16 TALLATE.

Valuable CAS 61791-00-2 / SURFACTANT - EMULSIFYING

PEG-16 Tallate is a polyethylene glycol ester of tall oil fatty acids, functioning primarily as a surfactant and emulsifier in precision skincare formulations. It effectively stabilizes oil-in-water mixtures and can contribute to skin hydration by attracting and retaining moisture.

Science

Mechanism of Action

As an emulsifying agent, PEG-16 Tallate works by significantly reducing the interfacial tension between otherwise incompatible oil and water phases, thereby facilitating the formation and long-term stability of emulsions. Its polyethylene glycol (PEG) component is known to enhance skin's moisture balance by forming hydrogen bonds with water molecules, promoting moisture retention and gradual delivery for sustained hydration. It also acts as a solubilizer for active ingredients, perfume oils, and colorants, a solvent, and a skin conditioner.

Stability

PEG-16 Tallate is an amphiphilic ingredient, possessing both hydrophilic (PEG) and lipophilic (tallate) characteristics essential for bridging oil and water phases. While PEGs generally exhibit high solubility in water, specific data for PEG-16 Tallate suggests very low water solubility (estimated at 0.01866 mg/L at 25 °C). Related PEG esters, such as PEG-100 Stearate, are known for their tolerance to salts and acids, maintaining stability across a wide pH range.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that PEG ingredients are generally safe for use in cosmetic products. They are minimally absorbed through intact skin, and in 2010, the CIR removed previous caveats regarding use on damaged skin, deeming it safe for both intact and compromised skin. While PEG-16 Tallate is recognized by the FDA under 'Tall oil fatty acids, PEG esters,' specific FDA status or SCCS review for this exact ingredient was not found. The overall risk of irritation or sensitization from the PEG family is considered low.
