Ingredients explained

Aqua/Water/Eau

Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.

Propylene Glycol

Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.

Hydroxypropyl Tetrahydropyrantriol

Antioxidant and skin conditioning agent; effective at low levels, test for sensitivity.

Glycerin

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

Dimethicone

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

Cetearyl Isononanoate

Blended ester emollient offering extensibility and lightness; non-comedogenic, good for oily to combo skin

Isohexadecane

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

PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin

PEG/PPG polybutylene glycerin humectant; monitor PEG oxidation and stability.

Diisopropyl Sebacate

Low-viscosity, high-flash-point ester; excellent spreadability, non-greasy feel

VP/VA Copolymer

VA/VP copolymer film former; provides hair fixing; avoid direct contact with eyes or mucous membranes.

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Phenoxyethanol

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

Polysilicone-11

Not decoded yet

Cellulose

Plant-derived thickener at 0.1–1%; requires full hydration, poor cationic compatibility

Hydrogenated Lecithin

Emulsifier from lecithin; stable, used in powder emulsions

Xanthan Gum

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

Propanediol

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

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.

Caprylyl Glycol

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

Panthenol

Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

Rhamnose

Polysaccharide humectant for hydration; used at low levels, mild flavor aid.

Ectoin

Cosmectin and skin protector, enhances skin tolerance; water-soluble, 0.1–5% common, compatible with most systems

Cassia Alata Leaf Extract

Anthraquinone-containing leaf extract; astringent and skin conditioner, anthraquinones may cause photosensitivity or irritation.

Maltodextrin

High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.

Sorbitol

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

Vaccinium Myrtillus Fruit Extract

Bilberry extract; anthocyanin rich; gentle antioxid/conditioning, no pub comed data

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Adenosine

Skin conditioner at 0.1-1%; used for anti-aging and repair

Trisodium Ethylenediamine Disuccinate

Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions

Punica Granatum Fruit Extract

Pomegranate extract for antioxidant conditioning; polyphenols may stain, need stabilizers.

Gentiana Lutea Root Extract

Plant root extract for conditioning and fragrance; may impart slight bitterness, test compatibility for sensitive skin

Hydrolyzed Soy Protein

Hydrolyzed soy protein for hydration and antistatic effect; soy is a common allergen requiring labeling, low comedogenicity.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Parfum/Fragrance

Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
