Formulation view Aqueous toner base featuring glycolic acid for exfoliation and zinc PCA for oil control. Glycerin provides hydration, with grapefruit extract as an additive. Factory view: The high concentration of AHA requires precise pH buffering (typically 3.0-3.8); Sodium Benzoate efficacy is optimal at this low pH, so pH stability is critical.

Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Trideceth-9
- Not decoded yet
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Peg-5 Ethylhexanoate
- Low-molecular PEG ester; used as solubilizer or emulsifier; ensure high purity to avoid impurity-related sensitization.
- Zinc Pca
- Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization
- Peg-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Disodium Edta
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Citrus Paradisi Fruit Extract
- Grapefruit extract; antioxidant, contains furanocoumarins (photosensitizing), use low concentration, avoid sun.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Hexyl Cinnamal
- Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
