Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- 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
- Bentonite
- Natural clay for oil absorption in masks or thickening; no allergenicity, ensure high purity batches
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Simmondsia Chinensis Seed Oil
- Common in dry/damaged hair; superior penetration vs mineral oils, low comedogenic risk, poor oxidative stability.
- Behenyl Alcohol
- Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.
- Polyvinyl Alcohol
- Film/viscosity agent for masks/cleansers; water-soluble, forms flexible film
- Methyl Gluceth-10
- Not decoded yet
- Phytosteryl/Isostearyl/Cetyl/Stearyl/Behenyl Dimer Dilinoleate
- Bio-mimetic lipid ester for emulsification and texture; provides high slip and is suitable for silicone-free formulas.
- Squalane
- Emollient from plants or synthetic; light texture
- Talc
- Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.
- Glyceryl Stearate SE
- Emulsifier at 1–3%; oil-phase ingredient, easy emulsification, low sensitization.
- Diatomaceous Earth
- Diatomaceous earth for oil absorption/opacification at 1–5%; high surface area, handle dust carefully.
- Polyglyceryl-10 Stearate
- Polyglyceryl-10 stearate emulsifier; multi-source, mild, co-emulsifier
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
- Batyl Alcohol
- Squalane, non-pungent emollient 0-5%; low irritation, suits dry/sensitive skin, emulsion stabilizer.
- Lauramide/Myristamide Dea
- Not decoded yet
- Moroccan Lava Clay
- Not decoded yet
- Beeswax
- Beeswax, natural thickener and film former; provides occlusive moisturization, natural honey scent, animal-derived, potential allergen
- Potassium Hydroxide
- Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Sucrose Stearate
- Succrose ester emulsifier/emolient with cleansing properties; HLB determines emulsion type.
- Iron Oxides
- Inorganic pigment for color; particulate form, inhalation risk low in cosmetics.
- Aluminum Hydroxide
- Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Dipotassium Glycyrrhizate
- Dipotassium glycyrrhizinate for moisturizing/soothing; inhibits 5-LOX, water-soluble, for sensitive skin.
- Honey
- Humectant/emollient; contains sugars requiring preservation, contraindicated for bee product allergies.
- Betula Platyphylla Japonica Juice
- Birch juice NMF 0.5-5%; aqueous, check preservatives & sugars
- Onsen-Sui
- Onsen hot spring water with minerals; mineral content varies, verify heavy metal levels.
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Daucus Carota Sativa Root Extract
- Carrot root extract with carotenoids; skin conditioning, low photosensitivity, may stain.
- Melissa Officinalis Leaf Extract
- Lemon balm extract for soothing; volatile oils, low allergy risk, light sensitive.
- Sodium Acetylated Hyaluronate
- Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.
- Rosmarinus Officinalis Leaf Extract
- Plant extract containing rosmarinic acid etc., with antioxidant and antimicrobial properties; may contain allergenic fragrances, patch test for sensitive skin, typical concentration <1%.
- Thymus Serpillum Extract
- Thymus serpyllum extract, contains active ingredients such as thymol, used as antibacterial and astringent agent; strong irritancy at high concentrations, dosage needs to be controlled.
- Glycine Soja Seed Extract
- Soybean extract for skin conditioning; low allergen risk, monitor batch protein variability.
- Soluble Collagen
- Water-soluble collagen for hydration, film-forming, hair care; MW affects permeation/film
- Salvia Officinalis Leaf Extract
- Herbal extract for seborrhea control, antibacterial action, and oral care; high levels may irritate sensitive skin.
- Cynara Scolymus Leaf Extract
- Artichoke leaf extract for skin conditioning; often in botanical blends.
- Lithospermum Erythrorhizon Root Extract
- Lithospermum erythrorhizon extract; naphthoquinones, 0.1–1%; antimicrobial, stains red, photo-sensitive, isolate light
