Role of 1,2-Hexanediol

Active Cosmetic Mechanisms

SKIN CONDITIONING

Skin Enhancer

Maintains skin in good condition and improves its feel

SCIENTIFIC ANALYSIS

// Evidence: Skin conditioning ingredients enhance appearance, texture, and health of skin through various mechanisms. This broad category encompasses emollients, humectants, occlusives, and other agents that improve skin feel, appearance, and function. May work by moisturizing, smoothing, softening, or protecting skin. Effects include improved tactile properties, enhanced barrier function, and better overall skin condition.

SOLVENT

Ingredient Dissolver

Dissolves other ingredients to create uniform formulations

SCIENTIFIC ANALYSIS

// Evidence: Solvents dissolve, dilute, or disperse other ingredients creating homogeneous solutions. Water is universal solvent for hydrophilic ingredients. Organic solvents include ethanol (dissolves fragrances, some actives), propylene glycol, and glycerin. Selection based on polarity matching between solvent and solute. Mechanism involves disrupting intermolecular forces in solute and surrounding with solvent molecules. Critical for maintaining ingredient solubility and product stability.
