DECENE.

Avoid CAS 872-05-9 / SOLVENT, VISCOSITY CONTROLLING

Decene, specifically 1-Decene, is primarily employed in cosmetic formulations for its ability to act as a solvent, facilitating the dissolution of other ingredients. It also plays a role in modifying the viscosity to achieve desired product consistency.

Solvent Viscosity Controlling Agent Dissolving Agent

Science

1-Decene functions within cosmetic formulations by serving as a solvent, effectively dissolving various components. Furthermore, it acts as a viscosity-controlling agent, enabling precise adjustment of the product's flow and thickness.

Safety

CIR Status
Insufficient data
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed 1-Decene as a standalone cosmetic ingredient, concluding 'insufficient data' for its individual safety profile. However, 'Decene/Butene Copolymer' was deemed safe. 1-Decene is categorized with hazard warnings for flammability (H226), potential fatality if swallowed (H304), and high toxicity to aquatic life (H410). It is described as a moderate to severe skin irritant, capable of defatting the skin, and an irritant to both the eyes and respiratory tract. Inhalation of elevated concentrations may lead to central nervous system depression.

Our Assessment

Avoid

Decene is not recommended for precision skincare due to insufficient independent safety data, its classification as a moderate to severe skin irritant, and significant handling precautions required for its flammable nature.
