Ingredients explained

Water/Eau

Water as base solvent; no irritation, but requires preservatives to prevent microbial growth.

Dimethicone

Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin

Isononyl Isononanoate

Light, low-viscosity ester emollient; excellent spreadability, good for gels and light lotions

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

Saccharum Officinarum Extract

Sugarcane extract, mainly moisturizing and conditioning; use at low levels; prone to microbes, needs preservatives.

Caprylic/Capric Triglyceride

Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

Glyceryl Stearate

Emulsifier at 1-3%; may require acid to prevent saponification

Hydroxyphenoxy Propionic Acid

3-Hydroxyphenylpropionic acid, phenolic antioxidant; stable but requires light protection, mild skin irritation at high levels.

PEG-100 Stearate

Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Algae Exopolysaccharides

Not decoded yet

Tetrapeptide-21

Tetrapeptide-21 often used for regeneration; requires temperature/light control and careful acid compatibility.

Beta-Glucan

Polysaccharide for soothing and hydration; high MW acts on the surface, poor penetration into deep dermis.

Algae Extract

Algae extract with humectant and conditioning effects; may contain natural fragrant components.

Camellia Sinensis Leaf Extract

Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.

Citrus Aurantium Dulcis Fruit Extract

Citrus peel extract, provides fragrance and astringency; photosensitive due to furanocoumarins; caution in daytime or remove photoactives.

Citrus Medica Limonum Fruit Extract

Citrus Medica Limonum fruit extract for scent and phenolics; contains photosensitizing furanocoumarins, use cautiously in daytime products.

Pyrus Malus Fruit Extract

Apple fruit extract, polyphenols for conditioning and antioxidant; batch variation needs standardization

Malus Domestica Fruit Cell Culture Extract

Cell-culture apple extract for antioxidant skin conditioning

Inula Crithmoide Extract

Not decoded yet

Bambusa Vulgaris Leaf/Stem Extract

Water-soluble botanical extract acting as humectant for oral or facial care; evaluate for potential natural allergens in the extract.

Glucosamine Hcl

Glucosamine hydrochloride for anti-static and hair conditioning; highly water-soluble, minimal skin irritation risk.

Pisum Sativum Extract

Pea extract, protein/antioxidant; skin protecting/conditioning, water-soluble, watch stability in acidic/enzymatic systems.

Ergothioneine

Ergothioneine, potent antioxidant; 0.01–0.1%, water-soluble, synergizes with Vit C/E.

Cetearyl Alcohol

Fatty alcohol emulsifier at 1-5%; non-ionic surfactant

Lecithin

Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.

Sorbitol

Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Ceteareth-20

Not decoded yet

Sclerotium Gum

Non-ionic gum for gels; neutral pH, requires dissolution via heating or fine milling

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Hexylene Glycol

Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Disodium EDTA

Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Benzoic Acid

Preservative and pH adjuster at 0.1–0.5%; low water solubility, best in acidic media, irritant at high levels.

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Citral

Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
