Science
Mechanism of Action
Decylene Glycol operates through a dual-action pathway: it acts as a humectant by attracting moisture to the stratum corneum and as an emollient to soften the skin surface. Beyond hydration, its molecular structure allows it to disrupt the phospholipid membranes of microorganisms—effectively inhibiting the growth of acne-causing bacteria—while simultaneously lowering the surface tension of the formulation to improve the penetration of co-delivered active ingredients.

Key findings
- 01 An in vivo 28-day study on oily skin subjects utilizing a 2% concentration demonstrated effective sebum modulation and skin compatibility.
- 02 In vitro ocular assays confirmed a non-irritant status at a 1% concentration in neutral oil carriers.
- 03 Usage levels between 0.5% and 1.5% are clinically recommended for maintaining product stability and antimicrobial efficacy in leave-on systems.

Dusting Analysis
Because Decylene Glycol functions effectively as a booster and texture enhancer at very low concentrations (starting at 0.1%), it is rarely 'dusted' for marketing purposes. It is typically included at functional levels to support the preservation system or penetration enhancement.
The Formula
Formulation
Stability
Thermally stable up to 90°C; however, prolonged exposure to high heat should be avoided to maintain molecular integrity.
Synergies
- Salicylic Acid
- Preservative systems
- Active actives requiring deep penetration
Safety
Safety Profile
Extensively reviewed by the CIR and found to be non-genotoxic and non-sensitizing. It is chemically distinct from the toxic Diethylene Glycol (DEG).
