Role of Peg-6 Undecylenate

Active Cosmetic Mechanisms

ANTI-SEBORRHEIC

Scalp Condition Treatment

Controls seborrheic dermatitis and associated scalp flaking

SCIENTIFIC ANALYSIS

// Evidence: Anti-seborrheic agents address seborrheic dermatitis involving excessive sebum production, Malassezia yeast overgrowth, and inflammatory response. These ingredients typically include antifungal compounds (zinc pyrithione, ketoconazole, selenium sulfide), keratolytics (salicylic acid), and anti-inflammatory agents. They work by normalizing keratinization, reducing fungal colonization, and controlling inflammation.

SURFACTANT - CLEANSING

Cleansing Surfactant

Removes 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.
