Ingredients explained

Water

Primary solvent and base; requires preservative system to prevent microbial growth

C12-15 alkyl benzoate

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

Titanium Dioxide

Physical UV filter and colorant up to 25%; nano form requires attention

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Butylene Glycol

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

Acrylates Copolymer

Acrylate synthetic polymer for film forming and antistatic; breathable film, control dosage carefully

Niacinamide

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

Cetyl Ethylhexanoate

Synthetic oil providing slip; large molecule, low penetration, non-comedogenic, suitable for dry or rough skin.

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Aluminum stearate

Aluminum stearate used as anticaking, emulsion stabilizer, and viscosity controller; restricted to IV/150 uses, avoid direct contact with acids.

Polyhydroxystearic acid

Emulsifier and stabilizer at 1–3%; non-ionic, prone to hydrolysis.

Pentylene Glycol

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

Polymethylsilsesquioxane

Silicone polymer for emolliency, matte effect, and suspension; used in foundations or powder suspensions, typical usage 1-5%, smooth skin feel.

Caprylic/Capric Triglyceride

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

Pinus Pinaster Bark Extract

Bark extract used as an antioxidant; ensure consistent raw material sourcing.

Olive Fruit Oil

High-linoleic occlusive moisturizer; heavy texture, comedogenic risk for oily skin

Ficus Carica Fruit Extract

Fig fruit extract, humectant with polysaccharides and enzymes for skin moisturizing

Centella Asiatica Extract

Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.

Lactobacillus Ferment Lysate

Lactobacillus ferment lysate for skin conditioning; provides soothing and hydration, low sensitization risk if sterile.

Sodium Hyaluronate

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

Glycerin

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

Hydrogenated lecithin

Emulsifier from lecithin; stable, used in powder emulsions

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Hydroxypropyl Methylcellulose Stearoxy Ether

Cellulose derivative for thickening and emulsion stabilization; cold or hot solubility depends on process, confirm dissolution method.

Sodium stearoyl glutamate

Mild amino-acid surfactant, poor solubility, pairs with fatty alcohols, fine foam.

Polyacrylate Crosspolymer-6

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

Tocopherol

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

Astaxanthin

Potent lipophilic antioxidant from algae; effective at trace levels (0.001-0.01%), prone to photodegradation, requires encapsulation or protection.

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Sodium Hyaluronate Crosspolymer

Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.

Hydrolyzed Hyaluronic Acid

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

Ascorbyl Propyl Hyaluronate

Combines antioxidant and moisturizing effects; unstable in alkaline pH, avoid direct contact with high metal ion concentrations

Hydroxypropyltrimonium Hyaluronate

Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.

Adenosine

Skin conditioner at 0.1-1%; used for anti-aging and repair

Ammonium Acryloyldimethyltaurate/VP Copolymer

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

Hydrolyzed Sodium Hyaluronate

Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.

Sodium Acetylated Hyaluronate

Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.

Xanthan Gum

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

t-Butyl alcohol

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

Ethylhexylglycerin

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