Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Cyclopentasiloxane

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

Myristyl Nicotinate

Nicotinate ester, vasodilator; high levels cause flushing, avoid mucosal contact.

C12-15 Alkyl Benzoate

C12-15 alkyl benzoate; emollient, emulsifier, and antistatic; aids stability and smoothness, moderate low comedogenicity.

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

PEG-40 Stearate

Water-soluble emulsifier for O/W; mild cleansing, high levels may be comedogenic, caution for sensitive skin.

PPG-3 Benzyl Ether Myristate

PPG-3 benzyl ether myristate, emollient emulsifier; contains PEG-like structure, low viscosity solvent, check ionic compatibility.

Ethylene/Acrylic Acid Copolymer

Water-soluble film former for matte feel; often used in emulsion form

Caprylyl Glycol

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

Ammonium Acryloyldimethyltaurate/VP Copolymer

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

Ammonium Acryloyldimethyltaurate/VP Copolymer

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

Sodium Polystyrene Sulfonate

Sodium polystyrene sulfonate, water-soluble polymer for thickening and emulsion stability; ion-tolerant

Phenoxyethanol

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

Acrylamide/Sodium Acryloyldimethyltaurate Copolymer

Polyacrylamide-based thickener with strong emulsion stabilizing power; strict control of residual monomer levels is required.

Polyimide-1

Sorghum Bicolor Stalk Juice

Not decoded yet

Isohexadecane

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

Benzyl Alcohol

Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

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

Aminomethyl Propanol

pH buffer at 0.1–1%; irritating at high levels, avoid direct mixing with strong acids/bases

Pullulan

Microbial polysaccharide for film forming and thickening; water-soluble film former used in capsules or moisturizing films.

Sorbic Acid

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

Tetrasodium EDTA

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

Polysorbate 80

Non-ionic emulsifier and solubilizer; watch for interaction with parabens

Benzoic Acid

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

Chlorphenesin

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

Cyathea Cumingii Leaf Extract

Not decoded yet

BHT

Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.

Ceramide 2

Not decoded yet

D-Limonene

Citrus terpene used as fragrance and skin conditioner; EU allergen, may cause sensitization at high levels, must be labeled.

Algae Extract

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

Malus Domestica Fruit Cell Culture Extract

Cell-culture apple extract for antioxidant skin conditioning

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Xanthium Sibiricum Fruit Extract

Not decoded yet

Cyperus Rotundus Root Extract

Herbal extract for soothing; use at low levels; watch for plant allergens

Lonicera Japonica Flower Extract

Honeysuckle extract for soothing; requires antimicrobial protection.

Lecithin

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

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Xanthan Gum

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Tetrapeptide-21

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

Lepidium Sativum Sprout Extract

Garden cress sprout extract, plant-based skin conditioner; may cause mild irritation in sensitive skin at high concentrations.

Dipropylene Glycol

Solvent for essential oils; better humectancy than PEG

Citrus Aurantium Dulcis Oil

Sweet orange oil; fragrance/antioxidant, contains furanocoumarins (photosensitizing), use at night or with SPF.

Hexamethylindanopyran

Hexamethylindanopyran fragrance material; restricted usage

Ethyl Linalool

Fragrance ingredient providing floral notes; listed as one of EU 26 allergens, labeling required.

Citrus Limon Fruit Extract

Lemon fruit extract for fragrance and occlusive moisturizing; contains furanocoumarins, photosensitivity caution advised.

Methyldihydrojasmonate

Methyl dihydrojasmonate, jasmine accord; synthetic fragrance, potential allergen.
