DI-C12-15 ALKYL FUMARATE.

Valuable / SKIN CONDITIONING - EMOLLIENT, SOLVENT

DI-C12-15 ALKYL FUMARATE is a sophisticated ester engineered to function as an emollient, delivering a light, silky, and satiny skin feel with notable anti-tack properties. Beyond its skin conditioning benefits, it serves as a versatile solvent and sensory modifier, enhancing the overall texture and stability of formulations.

Science

Mechanism of Action

This ingredient functions primarily by creating a smooth and soft surface on the skin, attributable to its emollient properties. It contributes a desirable 'silky' and 'satiny' feel while effectively reducing tackiness in formulations. Furthermore, within a product's matrix, DI-C12-15 ALKYL FUMARATE acts as a solvent and solubilizer, aiding in the dispersion of other components. It also influences rheology as a thickener and sensory modifier, allowing for precise control over solids concentration, viscosity, and melt point, while also supporting pigment wetting and solid binding.

Dusting Analysis

Not commonly dusted

This ingredient is a soft, white paste or solid at 25°C, melting near body temperature (approximately 40°C), and is therefore not typically associated with dusting behavior.

Stability

DI-C12-15 ALKYL FUMARATE transitions from a soft white paste/solid at 25°C to a liquid around 40°C (104°F), offering formulators an advantage in controlling product viscosity, solids concentration, and melt point. It provides extended playtime and cushioning, and a distinct viscosity reduction upon rub-out, transitioning from a thicker to a thinner consistency.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that Di-C12-15 Alkyl Fumarate is safe for use in cosmetic and personal care products, with the 100% pure ester demonstrating '0' irritation and sensitization potential. Studies on products containing this ingredient have shown a low potential for human sensitization. No explicit maximum concentration is specified by CIR, suggesting it can be used up to formulation requirements. The FDA includes Fumaric Acid and its salts on its list of permitted food additives, though DI-C12-15 ALKYL FUMARATE itself is not specifically addressed as a cosmetic ingredient.
