Active Cosmetic Mechanisms
DEODORANT
Odor NeutralizerMasks or neutralizes body odor
SCIENTIFIC ANALYSIS
// Evidence: Deodorants combat body odor through antimicrobial action against odor-causing bacteria (Corynebacterium, Staphylococcus), odor absorption/adsorption, enzymatic inhibition, or masking with fragrance. Active ingredients include antimicrobials, odor absorbers (zinc ricinoleate, cyclodextrins), and fragrances. They prevent bacterial conversion of sweat components into volatile malodorous compounds without reducing sweat volume.
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.
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.
