Active Cosmetic Mechanisms
FRAGRANCE
Scent ProviderAdds pleasant scent to cosmetic products
SCIENTIFIC ANALYSIS
// Evidence: Fragrance ingredients provide aromatic appeal through essential oils, aroma chemicals, and natural extracts. These volatile compounds interact with olfactory receptors creating scent perception. Fragrance design considers top notes (high volatility), middle notes (moderate volatility), and base notes (low volatility) for scent development over time. Must consider stability, allergen content, and regulatory compliance.
PERFUMING
Fragrance ProviderProvides fragrance to enhance product appeal
SCIENTIFIC ANALYSIS
// Evidence: Perfuming ingredients add pleasant scents through complex mixtures of natural essential oils, aroma chemicals, and synthetic compounds. These volatile molecules evaporate and interact with olfactory receptors. Perfume construction uses top notes (citrus, herbs - high volatility), middle notes (floral, spice - moderate volatility), and base notes (woods, musks - low volatility) creating evolving scent profile. Must consider stability, allergen declaration, and IFRA compliance.
SKIN CONDITIONING - EMOLLIENT
Skin SoftenerSoftens 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.
SOLVENT
Ingredient DissolverDissolves 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.
