Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Propanediol

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

Propylene Glycol

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

Hydroxyethylcellulose

Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.

Parfum

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

Phenylpropanol

Phenylpropanol for fragrance and solvent; allergen risk, requires assessment

Polysorbate 20

Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.

PEG-40 Hydrogenated Castor Oil

Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.

Ascorbyl Glucoside

Stable Vitamin C derivative, antioxidant; more stable than pure ascorbic acid, releases activity slowly in neutral/basic conditions.

1,2-Hexanediol

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

Sodium Citrate

Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.

Rhodomyrtus Tomentosa Fruit Extract

Rhodomyrtus extract. Natural humectant. Watch for potential plant allergens.

Tocopheryl Acetate

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

Disodium EDTA

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

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin

Citric Acid

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

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

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

Ethylhexylglycerin

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

Disodium Phosphate

Phosphate buffer for pH adjustment and preservation; water-soluble; high levels may irritate mucous membranes.

Polysorbate 60

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

Sodium Phosphate

Phosphate buffer and anti-seborrheic; pH regulator, aids sebum control, high levels are irritating
