Role of Peg-3 glyceryl isostearate

Active Cosmetic Mechanisms

SKIN CONDITIONING - EMOLLIENT

Skin Softener

Softens and smooths skin by filling gaps between cells

SCIENTIFIC ANALYSIS

// Evidence: Emollient ingredients create smooth, soft skin by filling spaces between corneocytes in stratum corneum. These include esters (isopropyl palmitate), oils (jojoba, argan), fatty alcohols, and silicones. The mechanism involves spreading on skin surface, filling microscopic irregularities, and creating lubricious film. Effects are immediate tactile improvement and visual smoothing. Emolliency measured by spreading coefficient and skin feel assessments.

SURFACTANT - EMULSIFYING

Emulsifying Surfactant

Blends 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.
