Ingredients explained
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Acetyl Hexapeptide-8
- Acetyl hexapeptide-8; signal peptide, low concentration, used for firming and hydration, low irritancy.
- Acetyl Octapeptide-3
- Not decoded yet
- Copper Tripeptide-1
- Copper Tripeptide-1 (GHK-Cu) for repair/anti-aging at 0.01–0.1%; water-soluble, avoid chelators.
- Bis-PEG-18 Methyl Ether Dimethyl Silane
- Silicone modifier for smoothness; contains PEG, used for foam and cleansing, manage PEG residuals
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Glycereth-25 Pca Isostearate
- Emulsifier and conditioning agent; 1–3% typical, low irritancy and comedogenicity
- Polyacrylate-13
- Not decoded yet
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer
- Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Polyisobutene
- Inert film former and occlusive; increases viscosity, slippery feel, used in lipsticks
- Citrus Aurantium Bergamia Fruit Oil
- Bergamot essential oil, natural fragrance and photosensitizer; limit daytime use or use FCF grade
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Sorbitan Isostearate
- Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- BHT
- Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Glycine
- Humectant amino acid, 1–3%; small molecule, low irritation.
