DESCRIPTION

What It Does: Provides osmoprotective humectant conditioning with anti-irritant and mild foam-boosting activity.

Why It's Used: Natural-origin multifunctional osmolyte from sugar beet providing hydration, anti-irritancy, and conditioning in virtually every cosmetic category.

How It Works: Quaternary ammonium betaine provides zwitterionic character for water binding via ionic hydration. osmoprotective function at 100–500mm as compatible solute protecting cells from osmotic stress. reduces surfactant irritation by competing with sls for protein binding sites. mild foam enhancement.

Typically Found In: Virtually all categories — moisturisers, shampoos, cleansers

SCIENTIFIC NOTE

Betaine's anti-irritant mechanism for surfactant systems involves competitive protein protection: betaine at high concentrations preferentially interacts with skin proteins, occupying binding sites that would otherwise be occupied by surfactant molecules causing protein denaturation. this competition reduces available protein binding for irritating surfactants, explaining betaine's well-documented ability to reduce sls irritation when co-formulated.

DESCRIPTION

What It Does: Provides molecular encapsulation for improved solubility, stability, and controlled release of challenging cosmetic actives.

Why It's Used: Molecular encapsulation technology — beta-cyclodextrin's toroidal cavity provides a hydrophobic microenvironment for solubilising and stabilising oil-soluble actives in aqueous formulations.

How It Works: 7 glucose units in cyclic toroidal structure provide 6.0-6.5å inner cavity. hydrophobic interior complexes lipophilic guest molecules. complexation improves water solubility (guest molecule becomes water-dispersible), stability (protection from oxidation and hydrolysis), and controlled release (guest releases gradually by diffusion). outer hydrophilic face provides water compatibility.

Typically Found In: Active delivery systems,fragrance encapsulation,stability-challenged actives

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: Provides skin surface hydration through hydroxyl group water binding, supports beneficial skin microbiome organisms as a selective fermentation substrate, and forms a conditioning film that reduces tewl.

Why It's Used: Natural polysaccharides combine humectant function with microbiome prebiotic activity — a dual benefit unavailable from synthetic humectants like glycerin, important for microbiome-conscious formulation.

How It Works: Hydroxyl groups on the polysaccharide backbone bind water through hydrogen bonding (5–7 h₂o molecules per sugar unit) providing hygroscopic moisture retention. fructans and inulins are selectively fermented by beneficial lactobacillus skin commensals providing a prebiotic microbiome benefit.

Typically Found In: Hydrating,microbiome support,barrier

DESCRIPTION

What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.

Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.

How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.

Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners
