It's A 10 Fragrance Free Miracle Leave-in Product

DESCRIPTION

What It Does: Softens and conditions skin by integrating into sc lipid bilayers, delivers essential fatty acids (oleic, linoleic, linolenic) for barrier lipid synthesis, and provides rich, non-stripping moisturisation.

Why It's Used: Natural carrier oils provide the closest compositional match to endogenous sc lipids, delivering emolliency through genuine barrier integration rather than simple surface occlusion.

How It Works: Fatty acid triglycerides partition into sc lipid bilayers — oleic acid (c18:1) provides fluid, emollient integration; linoleic acid (c18:2) acts as essential ceramide precursor; saturated fatty acids provide more occlusive barrier reinforcement.

DESCRIPTION

What It Does: Adsorbs to hair surface for superior conditioning, detangling, and static elimination.

Why It's Used: The premium quaternary ammonium conditioner – c22 chain length provides superior substantivity and lower irritation than ctab or dcdmh at equivalent conditioning performance.

How It Works: C22 quaternary ammonium adsorbs electrostatically to negatively charged hair cuticle (damaged hair has more negative sites, more adsorption where needed). forms a positively charged film reducing inter-fiber friction for detangling. c22 chain provides superior lubricant film vs shorter-chain quats. lower irritation than c16 ctac.

Typically Found In: Conditioners,hair masks,detangling sprays

DESCRIPTION

What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin — eliminating the residual heaviness of conventional liquid carrier solvents.

Why It's Used: Cyclosiloxanes are the unique volatile silicone solvents that dissolve non-volatile silicones (dimethicone, cyclomethicone), organic uv filters, and lipophilic actives, providing the sensory-superior dry-touch application experience in premium formulations.

How It Works: Cyclosiloxane vapour pressure (d5 cyclopentasiloxane ~0.3 mmhg at 25°c) provides clean evaporation at body temperature. the cyclic ring structure provides lower boiling point than equivalent linear dimethicone, enabling faster evaporation while the ring conformation maintains the silicone's low surface energy for smooth application.

DESCRIPTION

What It Does: Isopropyl alcohol dissolves oil-soluble and water-soluble cosmetic actives, provides rapid antimicrobial activity at concentrations above 60–70% by denaturing microbial proteins, delivers a refreshing cooling sensation through evaporative cooling on skin, and temporarily enhances the penetration of topical actives by transiently disrupting the stratum corneum lipid bilayer organisation.

Why It's Used: Formulators choose isopropyl alcohol for its irreplaceable combination of solvent power, antimicrobial activity, and penetration-enhancing properties. no other cosmetic solvent simultaneously provides the cooling sensory experience of alcohol (from evaporative cooling at the skin surface), the immediate antimicrobial activity required for sanitisers (from protein denaturation above 60%), and the transient sc lipid disruption that improves active ingredient delivery (essential in actives-rich toners and essences). for denatured alcohol specifically, denaturing agents (typically 5% isopropanol or bitrex) prevent consumption without affecting cosmetic function.

How It Works: Isopropyl alcohol works through multiple mechanisms depending on concentration: (1) solvent action — alcohol's hydroxyl group provides hydrogen bonding with water while the short alkyl chain provides interaction with organic solutes, enabling dissolution of both hydrophilic and moderately lipophilic cosmetic actives in a single solvent; (2) antimicrobial — above 60% concentration, ethanol denatures microbial proteins by disrupting non-covalent bonds maintaining protein secondary and tertiary structure — the alcohol molecules intercalate between protein chains, disrupting the hydrophobic interactions and hydrogen bonds that maintain enzyme active site geometry. this non-specific protein denaturation is immediately bactericidal and virucidal with no resistance mechanism possible; (3) sc penetration enhancement — at lower concentrations (5–30%), ethanol transiently fluidises the sc lipid bilayer by intercalating between the ordered lipid lamellae, disrupting the crystal packing and increasing lipid bilayer fluidity. this transient fluidisation increases the diffusion coefficient of co-applied actives through the sc for up to 30 minutes post-application; (4) astringency — alcohol's protein precipitating action at the skin surface contracts superficial proteins, temporarily tightening pores and reducing oiliness.

SCIENTIFIC NOTE

Ethanol concentration-dependent antimicrobial efficacy: below 40% — minimal bactericidal effect (insufficient protein denaturation); 40–60% — bacteriostatic, not bactericidal; 60–70% — peak bactericidal efficacy against both enveloped and non-enveloped viruses and vegetative bacteria (optimal water content maintains protein hydration required for denaturation to proceed); 80–90% — remains effective but slightly reduced from decreased water activity; 95–100% — reduced efficacy (insufficient water for protein denaturation). the 70% 'sweet spot' for sanitisers reflects this concentration-efficacy peak, not a formulation convenience.
