Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Mandelic Acid

Alpha-hydroxy acid for exfoliation and antibacterial effects; mild penetration, less photosensitivity than other AHAs

Glycerin

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

Dimethicone

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

Cyclopentasiloxane

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

C12-15 Alkyl Benzoate

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

Hydrolyzed Hyaluronic Acid

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

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Pentaerythrityl Tetraethylhexanoate

Esther emollient for a light, silky feel; heavy at high concentrations.

Polysilicone- 11

Not decoded yet

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.

Polyacrylate Crosspolymer-6

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

Arginine

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

Octyldodecyl Lactate

Ester emollient; low irritation, light feel, suitable for oily skin/summer formulas.

Caprylic/Capric Triglyceride

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

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

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

Squalane

Emollient from plants or synthetic; light texture

Tocopheryl Acetate

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

Sodium Hyaluronate

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

Xanthan Gum

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

Olea Europaea Fruit Extract

Olea europaea fruit extract rich in polyphenols for antioxidant and conditioning use; add preservative/antioxidant against oxidation.

Sodium Butyroyl Hyaluronate

Not decoded yet

Butylene Glycol

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

Polysorbate 60

Non-ionic emulsifier and solubilizer for O/W or W/O stability; may cause mild stinging on sensitive skin, typically 1-5%.

Decyl Glucoside

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

Sorbitan Isostearate

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

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.

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

Hexyl Cinnamal

Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).

Benzyl Salicylate

UV absorber/light stabilizer, restricted in EU; potential sensitizer, risk assessment needed.

Linalool

Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin

Citronellol

Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.

Limonene

Natural fragrance solvent, EU allergen; poor photostability

Alpha-Isomethyl Ionone

Vanilla-like fragrance ingredient; one of EU 26 allergens, caution advised for sensitive skin.

Coumarin

Classic fragrance and photosensitizer, EU restriction III/77; high allergen risk, limit in facial products

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.
