Science
Mechanism of Action
As an amphiphilic molecule with an HLB of approximately 13, Capryleth-5 lowers the surface tension between oil and water phases. This allows it to encapsulate oils and impurities into micelles, facilitating their removal during cleansing or maintaining a stable, uniform emulsion in leave-on creams and lotions.

Clinical Evidence
High confidence3%
Key findings
- 01 Clinical evaluations of alkyl PEG ethers demonstrated a negligible sensitization rate of less than 1% at standard usage concentrations.
- 02 A comprehensive safety review of 369 related ethers confirmed their safety profile in current cosmetic applications when formulated to be non-irritating.

Dusting Analysis
As a functional surfactant and emulsifier, Capryleth-5 is not typically 'dusted' for marketing purposes; it is included at specific levels required for formula stability. Inclusion below 0.5% may indicate a secondary role or insufficient concentration for primary emulsification.
The Formula
Formulation
Stability
Highly stable across a wide pH spectrum and compatible with electrolyte-rich environments. However, it is prone to autoxidation and peroxide formation if exposed to light and oxygen, requiring airtight or opaque packaging.
Synergies
- Electrolytes
- Chelating agents
- Antioxidants (to prevent autoxidation)
Conflicts
- Strong oxidizing agents
- Phenolic preservatives
Safety
Safety Profile
Safety is contingent on the removal of manufacturing by-products like 1,4-dioxane and ethylene oxide. Formulations must be tested for irritancy at higher concentrations.
