Ingredients explained

Aqua

Solvent, main base; microbial control is critical

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

Dimethyl Isosorbide

Dimethyl isosorbide as solvent and viscosity control; low toxicity, common use

Butylene Glycol

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

Undecane

Undecane; light aliphatic hydrocarbon emollient; high volatility, pair with occlusives, flammable

Arginine

Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.

Inulin

Plant fiber/prebiotic for moisturizing; fully dissolve to avoid crystallization

Microcrystalline Cellulose

Cellulose derivative for anti-caking, oil absorption, and physical sunscreen carrier; water-insoluble, affects texture at high levels.

Ceteareth-20

Not decoded yet

Tridecane

Tridecane, a long-chain alkane acting as emollient and solvent; petrochemical-derived, inert and low toxicity.

Tocopherol

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

Hydroxyacetophenone

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

Sodium Hyaluronate

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

Palmitoyl Tripeptide-38

Palmitoyl tripeptide; signaling peptide for collagen and antioxidants; 0.1-1% typical, light-sensitive

Panthenol

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

Caprylic/Capric Triglyceride

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

Palmitoyl Tripeptide-5

Peptide actives for skin conditioning; typically used at low levels.

Polyacrylate Crosspolymer-6

Water-soluble thickener; requires neutralizer, performs best at pH 5–7

Palmitoyl Tripeptide-1

Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase

Pullulan

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

Tetrapeptide-21

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

Palmitoyl Tetrapeptide-10

Not decoded yet

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers

Ammonium Polyacryloyldimethyl Taurate

Cationic water-soluble polymer; stabilizer and conditioner, test compatibility with anions

Glyceryl Linoleate

Glyceryl linoleate; emulsifier and emollient; oxidation-prone, requires antioxidants

Acetyl Hexapeptide-8

Acetyl hexapeptide-8; signal peptide, low concentration, used for firming and hydration, low irritancy.

Pentapeptide-18

Peptide for skincare; added at low levels, check supplier data for stability.

Oligopeptide-1

Synthetic peptide for skin repair; small size allows permeation, limited clinical data.

Arginine/Lysine Polypeptide

Arginine/Lysine polypeptide for skin conditioning; biologically derived, small molecular weight, high safety profile

Sucrose Palmitate

Succrose ester for gentle emulsification/cleansing; biodegradable, low comedogenicity.

Cetyl Palmitate

Waxy ester increasing viscosity and providing heavy feel; used as emulsifier carrier, low comedogenicity, strong occlusion.

Phenoxyethanol

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

Ethylhexylglycerin

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

Helianthus Annuus Seed Oil

Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.

Hydroxypropyl Cyclodextrin

Cyclodextrin to complex fragrances/actives; boosts solubility and stability.

Dimethicone/Vinyl Dimethicone Crosspolymer

Crosslinked silicone thickener at 0.5-2%; silky/matte feel, non-comedogenic, partial oil phase incompatibility, use co-solvent/pre-emulsification.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Hydrogenated Lecithin

Emulsifier from lecithin; stable, used in powder emulsions

Caprylyl Glycol

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

Pantolactone

Pantolactone, humectant; hydrolyzes to release panthenol, improves skin hydration, low level use, high safety

Xanthan Gum

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

Disodium EDTA

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

T-Butyl Alcohol

Fast-evaporating solvent; sharp odor and potential irritation at high levels, limit usage

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

Glyceryl Caprylate
