Ingredients explained

Aqua [Water]

Not decoded yet

Glycerin

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

Butylene Glycol

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

Coco-Caprylate/Caprate

Lightweight mid-chain ester, quick spreading, suitable for oily skin, non-comedogenic.

Prunus Amygdalus Dulcis Oil

Sweet almond oil, light emollient; suitable for sensitive skin, caution for nut allergies.

Isostearyl Alcohol

Non-ionic emulsifier and thickener providing body; at 2-5% enhances emulsion stability.

Hydrogenated Polyisobutene

Hydrogenated polyisobutene; petroleum-derived lubricant forming breathable film; high purity, low irritation/comedogenicity.

Phenylbenzimidazole Sulfonic Acid

UV absorber and light stabilizer; compliant use required, common in sunscreens

Glucose

Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.

Butylene Glycol Cocoate

Butylene glycol cocoate, non-ionic emulsifier and emollient; low irritancy, low comedogenicity, used in mild emulsifying systems.

Tromethamine

pH adjuster, alkaline; precise dosing required

Peg-8

Not decoded yet

Tocopheryl Acetate

Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light

Triethanolamine

Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

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

1,2-Hexanediol

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

Isoceteth-20

Not decoded yet

Caprylyl Glycol

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

Hydrolyzed Wheat Protein

Hydrolyzed protein for hair and skin conditioning; potential allergen, use low levels in sensitive products

Diazolidinyl Urea

Formaldehyde-releasing preservative; EU cap at 0.2%; avoid for formaldehyde-sensitive users

Xanthan Gum

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

Caprylic/Capric Triglyceride

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

Parfum [Fragrance]

Not decoded yet

Ethylcellulose

Water-insoluble film former and viscosity builder for suspensions; requires dispersion or premixing.

Ascorbyl Tetraisopalmitate

Vitamin C ester antioxidant; more stable than ascorbic acid but still light-sensitive.

Tetrasodium Edta

Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.

Hydrogenated Vegetable Oil

Occlusive emollient for smooth feel; high levels may be comedogenic, use caution for acne-prone skin

Glyceryl Acrylate / Acrylic Acid Copolymer

Not decoded yet

Phenoxyethanol

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

Sorbitol

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

Ppg-1-Peg-9 Lauryl Glycol Ether

Not decoded yet

Procollagen

Not decoded yet

Ethylhexylglycerin

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

Citric Acid

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

Crithmum Maritimum

Not decoded yet

Palmitoyl Methoxytryptamine

Not decoded yet

Hydrolyzed Elastin

Hydrolyzed elastin, moisturizer; MW determines penetration, large MW surface conditioning.

Citronellol

Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.

Soluble Collagen

Water-soluble collagen for hydration, film-forming, hair care; MW affects permeation/film

Geraniol

Geraniol for fragrance; EU 26 allergen, labeling required above 0.001%.

Quaternium-15

Not decoded yet

Benzoic Acid

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

Sorbic Acid

Preservative effective at low pH, often combined with sorbate salts; check regulatory limits

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Ci 16035

Azo hair dye component, requires alkaline activation. Restricted to professional hair use, not for daily wash.

Ci 19140

Acid Yellow 23 lake; for coloring and hair dyeing. High water solubility and precipitation risk, pH control required.
