Ingredients explained

Water (Aqua

Solvent and base; pharmaceutical grade recommended for active formulations.

Eau)

Pure water, solvent and diluent; drinking water standard, no known allergens or irritation

Butylene Glycol

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

Dimethicone

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

Glycerin

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

Isohexadecane

Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture

Ammonium Acryloyldimethyltaurate/VP Copolymer

Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.

Algae Exopolysaccharides

Not decoded yet

Porphyridium Cruentum Extract

Porphyridium cruentum extract, marine algae source, providing skin conditioning

Rhizobian Gum

Biofilm former and viscosity agent for hair; biocompatible and mild

Sea Water

Natural ingredient with salts; acts as solvent or humectant, high salt content may feel gritty

Enteromorpha Compressa Extract

Compressed Ulva extract, skin protector; watch microbe/heavy-metal QC on algal extracts.

Citrullus Lanatus Fruit Extract

Watermelon extract; L-citrulline/sugar; low-conc humectant, mild, no pub comed data

Lens Esculenta Fruit Extract

Lentil extract; protein/sugar; low-conc conditioning, mild, no pub data

Pyrus Malus Fruit Extract

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

Beta-Glucan

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

1,2-Hexanediol

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

Magnesium Aspartate

Magnesium aspartate; water-soluble chelant/conditioner. Use at 1-2%; check chelation efficiency.

Zinc Gluconate

Chelated zinc salt with antimicrobial and deodorizing effects; used in antiperspirants and oral care; has EU concentration limit.

Chondrus Crispus Extract

Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive

Copper Gluconate

Copper gluconate; trace antioxidant/repair agent. Use <0.05%; high levels cause color change/irritation.

Sodium Hyaluronate Crosspolymer

Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Disodium EDTA

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

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Propanediol

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

Ethylhexylglycerin

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

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Pentylene Glycol

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

Caprylyl Glycol

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

Chlorphenesin

Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.

Phenoxyethanol

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

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Benzyl Benzoate

Chelating agent for stability; restricted substance, not permitted as single component or in mixtures at ≥0.1%.

Butylphenyl Methylpropional

Synthetic fragrance with floral notes; EU regulations limit usage, strict monitoring required.

Hexyl Cinnamal

Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).

Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde

Prohibited in EU cosmetics; restricted due to irritation risks.

Blue 1

Synthetic water-soluble dye for color; use within regulatory limits
