DECETH-5.

Valuable CAS 26183-52-8 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

DECETH-5 is a versatile non-ionic surfactant and emulsifying agent derived from decyl alcohol. It plays a critical role in stabilizing oil-in-water formulations while enhancing the spreadability and cleansing efficiency of topical products.

Science

As an amphiphilic molecule, DECETH-5 possesses both hydrophilic (water-binding) and hydrophobic (oil-binding) segments. It functions by reducing surface tension and encapsulating non-polar impurities like sebum and environmental debris, allowing them to be suspended in water and rinsed away without stripping the skin's barrier.

Stability

Highly resilient across a broad pH spectrum, DECETH-5 remains active in acidic, neutral, and mildly alkaline environments. It exhibits excellent solubility in water and low aliphatic alcohols, making it effective even in cold-process formulations.


Safety

CIR Status
Safe as used with restrictions
Pregnancy
Safe
Sensitization risk Low

The CIR Expert Panel deems Deceth ingredients safe when formulated to be non-irritating. While ethoxylation can produce trace 1,4-dioxane, modern purification protocols effectively control these levels to ensure consumer safety.
