Ingredients explained
- Water/Eau
- Water as base solvent; no irritation, but requires preservatives to prevent microbial growth.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Collagen
- Hydrating conditioning agent; soluble protein used in hair care and toners; forms occlusive layer.
- Gold
- Gold in nano or microparticle form, for coloring and slip; usage restricted by regulations
- Caesalpinia Spinosa Fruit Extract
- Plant extract for skin protection; contains antioxidants, may need stabilizers at high conc.
- Kappaphycus Alvarezii Extract
- Seaweed polysaccharide; film forming and moisturizing; provides gel texture; gentle.
- Palmitoyl Tripeptide-1
- Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase
- Palmitoyl Tetrapeptide-7
- Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Agar
- Natural polysaccharide gelling agent for thickening and suspension; may gel at high levels, avoid cationic systems
- Calcium Alginate
- Natural polysaccharide used as thickener and gel base; usually food-grade, but listed as fragrance here, verify supply chain origin.
- Gellan Gum
- Gellan gum; water-soluble polymer; gel former; high transparency, strong gelling, for aqueous phase stability.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Sodium Lactate
- Sodium lactate for moisturizing and exfoliation; pH buffering agent
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Leuconostoc/Radish Root Ferment Filtrate
- Bio-fermented filtrate for antimicrobial and anti-dandruff effects; assess individual variability, avoid in known allergy.
- Iron Oxides
- Inorganic pigment for color; particulate form, inhalation risk low in cosmetics.
- Mica
- Mineral colorant for pearlescence; heavy metal screening required
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
