Steareth-15
In Skincare: Is Steareth-15 Safe? Comedogenic Rating & Side Effects
Overview
Ingredient Profile
Role of Steareth-15
Active Cosmetic Mechanisms
CLEANSING
Dirt & Oil RemoverRemoves dirt, oil, makeup, and impurities
SCIENTIFIC ANALYSIS
// Evidence: Cleansing ingredients remove sebum, dirt, cells, and cosmetics through surfactant action, emulsification, or solubilization. Surfactants reduce surface and interfacial tension, allowing water to wet oily surfaces. Micelle formation enables hydrophobic substances to be solubilized and rinsed away. Must balance efficacy with mildness to avoid stripping natural lipid barrier.
SURFACTANT - CLEANSING
Cleansing SurfactantRemoves dirt and oil through surfactant action
SCIENTIFIC ANALYSIS
// Evidence: Cleansing surfactants specifically formulated for removing sebum, dirt, and impurities. Primarily anionic (sodium laureth sulfate, sodium cocoyl isethionate) and amphoteric surfactants (betaines). Mechanism involves reducing surface tension enabling water to wet oily surfaces, solubilizing lipophilic materials in micelles, and emulsifying oils for rinse-off. Cleansing efficacy balanced with mildness by surfactant selection, concentration, and pH optimization. Must avoid excessive lipid removal that compromises barrier function.
SURFACTANT - EMULSIFYING
Emulsifying SurfactantBlends oil and water phases into stable mixtures
SCIENTIFIC ANALYSIS
// Evidence: Emulsifying surfactants enable creation of stable oil-in-water or water-in-oil emulsions by positioning at oil-water interface, reducing interfacial tension. HLB (hydrophilic-lipophilic balance) determines emulsion type: HLB 3-6 for W/O, HLB 8-18 for O/W emulsions. Examples include polysorbate 80, ceteareth-20, glyceryl stearate. Mechanism involves forming interfacial film preventing droplet coalescence. Often used in combinations with co-emulsifiers (fatty alcohols) creating lamellar structures for enhanced stability.
