Ingredients explained
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Saccharomyces/Camellia Sinensis Leaf/Cladosiphon Okamuranus/Rice Ferment Filtrate*
- Multi-strain ferment filtrate with yeast and green tea; provides moisturizing and conditioning; purity critical.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Diglycerin
- Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.
- Diphenylsiloxy Phenyl Trimethicone
- Phenyl trimethicone for anti-foaming and slip; silicone-based, silky feel
- Gold
- Gold in nano or microparticle form, for coloring and slip; usage restricted by regulations
- Belamcanda Chinensis Root Extract
- Belamcanda chinensis root extract; rich in irisin; soothing and repair focus
- Rosa Multiflora Fruit Extract
- Wild rose fruit extract rich in polyphenols; provides antioxidant and aromatic notes; check essential oil allergens
- Houttuynia Cordata Extract
- Houttuynia cordata extract for anti-inflammatory and soothing effects; contains volatile oils, patch test recommended for sensitive skin.
- Sophora Angustifolia Root Extract
- Sophora root extract; matrine-rich with antimicrobial and anti-itch effects, used for skin conditioning.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Lecithin
- Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.
- Pistacia Lentiscus Gum
- Frankincense resin for film formation and fragrance; natural source, high doses may sensitize
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Mica
- Mineral colorant for pearlescence; heavy metal screening required
- Peg-9 Polydimethylsiloxyethyl Dimethicone
- PEG-modified silicone with emulsifying and conditioning properties; ensure low dioxane levels in finished goods.
- Dimethicone/Peg-10/15 Crosspolymer
- Silicone/PEG crosspolymer for film forming and viscosity; low irritation; PEG debate at high conc
- Dimethicone/Phenyl Vinyl Dimethicone Crosspolymer
- Silicone crosspolymer for viscosity control; slip feel, hydrophobic, ensure silicone phase compatibility.
- Disodium Edta
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Tin Oxide
- Inorganic mineral pigment providing opacity and suspension; requires skin safety assessment, typically used in sunscreens or powder colorants.
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
