Formulation view A hybrid sunscreen combining physical titanium dioxide with chemical filters for broad-spectrum protection. A PEG emulsion system ensures a light texture, while aloe provides soothing for daily use on all skin types. Formulator insight: the combination of various UV absorbers complicates photostability management, necessitating strict pH monitoring to prevent increased irritation from co-solvents.

Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- PVP Hexadecene Copolymer
- Not decoded yet
- 4-Methylbenzylidene Camphor
- UVB filter, requires combination with UVA filters; provides photostability, usage limit by regulation.
- Phenylbenzimidazole Sulfonic Acid
- UV absorber and light stabilizer; compliant use required, common in sunscreens
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Ceteareth-20
- Not decoded yet
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Isopropyl Myristate
- Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin
- Aloe Barbadensis Extract
- Standardized aloe extract. Soothing and moisturizing; verify anthraquinone (allergen) removal. High purity usually well-tolerated.
- Butyl Methoxydibenzoylmethane
- High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Diazolidinyl Urea
- Formaldehyde-releasing preservative; EU cap at 0.2%; avoid for formaldehyde-sensitive users
- Methyl Paraben
- Effective water-soluble preservative; generally safe at low concentrations, may cause sensitivity in susceptible individuals.
- Propyl Paraben
- Not decoded yet
- Polysorbate 80
- Non-ionic emulsifier and solubilizer; watch for interaction with parabens
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Algae Extract
- Algae extract with humectant and conditioning effects; may contain natural fragrant components.
