- Diethylhexyl Succinate
- Succinyl diisobutyrate, lightweight emollient and solvent; good spread, non-comedogenic
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Aqua/Water
- Solvent, formulation base; requires preservation, pure water is microbially prone.
- Drometrizole
- Broad-spectrum UV filter at 1–5%; photostable at typical doses
- Trisiloxane
- Used as anti-foaming and lubricant; provides silkiness, used at low levels.
- Ethylhexyl Triazone
- UVB absorber with good photostability; formulated with other filters, typical concentration 3-5%, check compatibility with other ingredients.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Diethylamino Hydroxybenzoyl Hexyl Benzoate
- Novel UVB absorber at 0.2-1.5%; narrow band, requires combination, high photostability, verify regional limits, low irritation.
- Terephthalylidene Dicamphor Sulfonic Acid
- UV absorber and light stabilizer; EU regulated, check max levels and formulation stability
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Behenyl Alcohol
- Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.
- Methyl Trimethicone
- Methyl trimethicone, light volatile silicone; non-comedogenic, good powder compatibility.
- Sodium Polyacryloyldimethyl Taurate
- Sodium polyacryloyldimethyl taurate for emulsion stabilization and thickening; ionic polymer, check ion compatibility.
- Hamamelis Virginiana Leaf Water
- Astringent/soothing water with tannins; aqueous, high preservation needs; tannins may irritate
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Polyacrylate Crosspolymer-6
- Water-soluble thickener; requires neutralizer, performs best at pH 5–7
- Arachidyl Alcohol
- Waxy emulsion stabilizer and thickener, often paired with cetearyl alcohol; heavy feel, good for creams
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Arachidyl Glucoside
- Mild non-ionic emulsifier and emollient, PEG-free; co-soluble with stearoyl lactylates
- Sodium Metaphosphate
- Sodium metaphosphate; buffer and chelating agent; good water solubility, strongly alkaline, precise dosing required
- Adenosine
- Skin conditioner at 0.1-1%; used for anti-aging and repair
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
