Aloe juice, humectant and fragrance; perishable, requires preservatives, prone to browning.

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

2-Hexanediol

2-Hexanediol; branched-chain diol solvent and co-preservative, mild odor, weak humectant.

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

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
