Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Octocrylene

UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.

Methylene Bis-Benzotriazolyl Tetramethylbutylphenol

UV stabilizer (UV-326/328) preventing photo-degradation of formulas; has EU concentration limit, used in sunscreens.

Ethylhexyl Salicylate

Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.

Cyclopentasiloxane

Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.

Butyl Methoxydibenzoylmethane

High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.

Diethylhexyl Carbonate

Light emollient for silky texture; non-comedogenic, suits most skin types.

Alcohol Denat

Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.

Silica

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

Titanium Dioxide

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

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine

UV-B absorber, photostable; high purity and low bioaccumulation, check for impurities.

Niacinamide

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

Dibutyl Adipate

Light ester, solvent and emollient, fresh feel and volatility, non-comedogenic.

Butylene Glycol

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

Bis-PEG/PPG-20/5 PEG/PPG-20/5 Dimethicone

Non-ionic silicone emulsifier for stabilizing emulsions; provides a silky texture.

Methoxy PEG/PPG-25/4 Dimethicone

Modified silicone emulsifier combining emollience and emulsification to adjust product texture.

Ethylhexyl Methoxycinnamate

UVA absorber used with other filters; poor water stability and photolability, requires light stabilizers, max concentration typically 10%.

Glyceryl Stearate

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

Ceteareth-25

Not decoded yet

Triethylhexanoin

Light ester for non-greasy feel and fragrance; low allergenicity, high levels can act as solvent

Isohexadecane

Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture

Decyl Glucoside

Mild alkyl glucoside, biodegradable; foam stabilizer, thickens with fatty alcohols, low allergenicity.

Caprylic/Capric Triglyceride

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

Tocopheryl Acetate

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

Allantoin

Skin soother at 0.5-2%; promotes cell regeneration

Bisabolol

Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.

Oryzanol

Rice-bran antioxidant for skin conditioning and sebum balance

Artemisia Umbelliformis Extract

Not decoded yet

Buddleja Davidii Leaf Extract

Not decoded yet

Peucedanum Ostruthium Leaf Extract

Peucedanum leaf extract for skin conditioning; contains coumarins, assess phototoxicity risk

Pinus Pinaster Bark/Bud Extract

Dimethicone

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

Polymethyl Methacrylate

PMMA for thickening, suspension, and film; micro-size powder carrier, very low irritation

Aluminum Stearate

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

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

High-molecular-weight thickener and emulsion stabilizer; requires electrolytes or acid adjustment near isoelectric point for optimal performance.

Xanthan Gum

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

Polyisobutene

Inert film former and occlusive; increases viscosity, slippery feel, used in lipsticks

Polyhydroxystearic Acid

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

Alumina

Alumina, inorganic abrasive/thickener; nano-grade requires inhalation risk assessment.

PEG-8

Not decoded yet

Glycerin

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

PEG-7 Trimethylolpropane Coconut Ether

PEG-containing non-ionic surfactant for emulsification and cleansing; monitor PEG contamination and sensitive skin compatibility.

Propylene Glycol

Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.

Tocopherol

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

Sorbitan Isostearate

Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.

Diglycerin

Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.

Ascorbyl Palmitate

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

Ascorbic Acid

Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.

Citric Acid

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

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

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate

High-efficiency lipid-soluble antioxidant preventing oil rancidity; very low usage, typically 0.05-0.1%, ensure even distribution, avoid metal-catalyzed oxidation.

Disodium EDTA

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

Parfum

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