Ingredients explained

Water

Primary solvent and base; requires preservative system to prevent microbial growth

Cyclopentasiloxane

Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.

Butylene Glycol

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

Octyldodecyl Neopentanoate

Ester emollient; light oil feel; low irrit, low comed, good for fresh systems

Glycerin

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

Phenoxyethanol

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

Peg/Ppg-18/18 Dimethicone

PEG/PPG siloxane; emulsifier/thickener; low irrit, watch PEG total conc limits

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Dimethicone

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

Aluminum Hydroxide

Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Caprylyl Glycol

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

Titanium Dioxide

Physical UV filter and colorant up to 25%; nano form requires attention

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Sodium Dehydroacetate

Sodium dehydroacetate, preservative <0.5%; restricted for eye, children, and lip use.

Disodium Edta

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

Phytantriol

Botanical-derived humectant from phytane derivatives; enhances skin water retention

Hexylene Glycol

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

Glyceryl Acrylate/Acrylic Acid Copolymer

Acrylate copolymer for thickening and moisturizing; synthetic polymer with low sensitization risk.

Dextrin Palmitate

Modified polysaccharide ester for emulsifying and anticaking; mild cleanser; used in solid soaps or powders.

Palmitic Acid

Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.

Octyldodecanol

Light emollient/emulsifier at 1-5%; low comedogenic, non-greasy feel, broadly compatible, sensitive-skin friendly.

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Tetrahexyldecyl Ascorbate

Lipophilic Vitamin C derivative, antioxidant and brightening; more stable than VC, oil-soluble, must pair with oil phase

Tocopherol

Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light

Magnesium Ascorbyl Phosphate

Water-soluble Vitamin C derivative for antioxidant and brightening; more stable than ascorbic acid

Retinyl Palmitate

Vitamin A ester for skin conditioning; light-sensitive, requires protection, avoid in pregnancy.

Zinc Oxide

Physical UV filter, 30% max in EU; oily at high levels, pair with oils for feel.

Lysine

Amino acid conditioner for anti-static hair care; low irritation at typical cosmetic concentrations.

Triethoxycaprylylsilane

Silane coupling agent at 0.1-0.5%; enhances inorganic filler adhesion, trace use, low toxicity, avoid direct contact with aqueous systems.

Camellia Sinensis Leaf Extract

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

Chamomilla Recutita Flower Extract

Plant extract, soothing properties; contains natural allergens, high levels may irritate.

Ginkgo Biloba Leaf Extract

Antioxidant and microcirculation modifier rich in flavonoids; requires stability testing to prevent oxidation

Panax Ginseng Root Extract

Botanical extract for skin and hair conditioning; activity and irritation risk vary by source/purity, patch test for sensitive skin

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Magnesium Chloride

Inorganic salt for thickening and pH adjustment; 0.1-1%, avoid calcium ions

Potassium Chloride

Viscosity modifier for gels and shampoos; high concentrations may cause local stinging.

Zinc Chloride

Antimicrobial astringent for oral care; usage levels are restricted.

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Montmorillonite

Not decoded yet

Illite

Mineral powder offering slip and coverage. Iron content may introduce slight color variation to the formula.

Kaolin

Kaolin absorbent and bulk for powders/masks; check for heavy metals and comply with EU colorant limits IV/119
