Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Dicaprylyl Carbonate

Light emollient solvent at 5–15%; mineral oil-free, refreshing feel, low sensitization.

Butylene Glycol

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

Caprylic/Capric Triglyceride

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

PEG-100 Stearate

Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.

Glyceryl Stearate

Emulsifier at 1-3%; may require acid to prevent saponification

Betaine

Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.

Glycerin

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

Sorbitol

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

Sodium Hyaluronate

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

Tocopherol

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

Tocopheryl Acetate

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

Ascorbyl Palmitate

Ascorbyl palmitate, lipophilic Vit C ester, antioxidant; oxidizes, needs light/air protection.

Retinyl Palmitate

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

Urea

Potent humectant and keratolytic, >10% has exfoliating effect; stinging sensation at high levels, sensitive skin caution

Erythritol

Polyol humectant with light feel; high hygroscopy, watch in dry climates.

Trehalose

Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.

Lecithin

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

Serine

Humectant amino acid, 1–3%; high water solubility, compatible with sensitive skin.

Tyrosine

Amino acid involved in melanin synthesis; used for hair conditioning.

Arginine

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

Histidine Hcl

Amino acid salt for pH buffering and hair conditioning; gentle buffering system, potential sensitization at high concentrations.

Phenylalanine

Amino acid for hair and skin conditioning; usually part of a blend, no significant standalone efficacy data

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Pyridoxine Hcl

Vitamin B6 HCl; trace skin/hair conditioning/antiox; very mild, high-conc pigmentation debate

Calcium Pantothenate

Pro-vitamin B5 for hair/skin conditioning; water-soluble, used in conditioners

Disodium Adenosine Triphosphate

ATP salt as skin conditioning agent; water-soluble, use at low concentrations.

Rna

Not decoded yet

Algin

Seaweed-derived thickener at 0.1–1%; provides gel texture, mind calcium ion compatibility

Pullulan

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

Thioctic Acid

Alpha-lipoic acid; potent antioxidant; poor water solubility, often used as ester derivatives

Ubiquinone

Coenzyme Q10 analog used as an antioxidant; prone to discoloration, needs protection from light and air.

Silica

Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products

Sodium Ascorbyl Phosphate

Vitamin C derivative antioxidant at 0.5–2%; light-sensitive, requires opaque packaging

Disodium EDTA

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

Arachidyl Glucoside

Mild non-ionic emulsifier and emollient, PEG-free; co-soluble with stearoyl lactylates

Dimethicone

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

Disodium Phosphate

Phosphate buffer for pH adjustment and preservation; water-soluble; high levels may irritate mucous membranes.

Potassium Phosphate

pH adjuster for buffering systems; 0.1-1%, avoid calcium and magnesium ions

Glyceryl Linolenate

Emollient/moisturizer; potential allergen, caution in sensitive skin

Glyceryl Linoleate

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

Arachidyl Alcohol

Waxy emulsion stabilizer and thickener, often paired with cetearyl alcohol; heavy feel, good for creams

Cetyl Alcohol

Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.

Behenyl Alcohol

Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.

Sodium Starch Octenylsuccinate

Modified starch for oil absorption/films/thickening, 2–8%; mildew risk in high humidity, needs preservatives.

Caprylyl Glycol

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

Glyceryl Polyacrylate

Water-soluble film former at 1–5%; light feel, soluble in polyols, non-occlusive

Maltodextrin

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

Mannitol

Polyol humectant with binding/skin conditioning properties; high levels may cause osmotic irritation

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Sodium Polyacrylate

Superabsorbent resin, <1%; gels with electrolytes, ionic strength control required.

Xanthan Gum

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

Citric Acid

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

Parfum

Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.

Glyceryl Caprylate

Mild emulsifier/deodorant at 0.5-2%; polyol ester, high humectancy, low irritancy, check cationic surfactant compatibility.

Ethylhexylglycerin

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

Phenoxyethanol

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