Answer

Analysis of Provided Ingredients

Here is an analysis of the ingredients you provided:

  • Deionized Water: The primary solvent, forming the base of most cosmetic emulsions.
  • ETHYLHEXYL METHOXYCINNAMATE: A common chemical UV filter that absorbs UVB radiation.
  • Paraffinum Liquidum: Mineral oil, often used as an emollient and occlusive agent to help skin retain moisture.
  • Polysorbate 20: A nonionic surfactant and emulsifier, helps mix oil and water components.
  • Glycerin: A humectant, attracts water to the skin, providing hydration.
  • TITANIUM DIOXIDE: A mineral UV filter that provides broad-spectrum protection (UVA and UVB). It also acts as a white pigment.
  • HYDROGEN Dimethicone: A silicone derivative, often used to treat pigments like Titanium Dioxide to improve dispersion and feel.
  • ISODECYL NEOPENTANOATE: A lightweight emollient that provides a smooth feel.
  • Butylene Glycol: A humectant and solvent, helps other ingredients penetrate the skin and improves texture.
  • SODIUM POLYACRYLOYLDIMETHYL TAURATE: A synthetic polymer used as a thickener, stabilizer, and emulsifier.
  • POLYACRYLAMIDE, C13-14 Isoparaffin, Laureth-7: These ingredients together form a polymer network (often known as Sepigel 305 or similar systems) used as a thickener and emulsifier, creating a gel-cream texture.
  • PINUS SYLVESTRIS OIL: Pine leaf oil, can be used for fragrance or potential skin benefits, though it can also be a potential irritant.
  • Phenoxyethanol: A common preservative used to prevent microbial growth.
  • Allantoin: A skin-conditioning agent known for its soothing and healing properties.
  • Disodium EDTA: A chelating agent that binds to metal ions, improving product stability and preventing discoloration.
  • MELALEUCA ALTERNIFOLIA LEAF OIL: Tea tree oil, known for its antiseptic and anti-inflammatory properties, often used in acne products, but can be irritating for some.
  • COCAMIDOPROPYL DIMETHYLAMINE: A surfactant or conditioning agent.
  • SALICYLIC ACID: A beta-hydroxy acid (BHA) used for exfoliation, treating acne, and improving skin texture.
  • Ethylhexylglycerin: A conditioning agent and preservative enhancer.

This formulation appears to be a sunscreen product (due to Ethylhexyl Methoxycinnamate and Titanium Dioxide) with moisturizing, thickening, and potentially some acne-treating or soothing ingredients (Salicylic Acid, Allantoin, Tea Tree Oil).
