Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Cyclopentasiloxane
- Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.
- 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
- PEG-10 Dimethicone
- Modified silicone for silky feel and shine; PEG structure aids O/W emulsification, used in hair and skin care.
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Talc
- Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.
- Disteardimonium Hectorite
- Inorganic ionic clay thickener at 0.25-1%; water/oil/solvent systems, rheology control, avoid strong acids, may affect active release.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Mica
- Mineral colorant for pearlescence; heavy metal screening required
- Isostearic Acid
- Fatty acid derivative as emulsifier auxiliary and emollient; insoluble, requires homogenization, may feel slightly greasy
- Aluminum Hydroxide
- Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Dimethicone Crosspolymer
- Crosslinked silicone polymer providing silkiness and viscosity control; for hair and skin; inert but hard to biodegrade.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Methicone
- Volatile silicone offering slip and antistatic properties; inert at high purity, check cyclic isomer limits
- Disodium Stearoyl Glutamate
- Amino acid-based mild cleanser with fine foam; water-soluble.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Ci 77491
- Iron oxides red; physical pigment. Coloring and photo-protective, stable and non-irritating.
- Ci 77492
- Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
- Ci 77499
- Inorganic colorant manganese dioxide used in cosmetics; restricted use component subject to regulatory limits.
- Ci 77891
- Titanium dioxide inorganic pigment and UV filter; assess inhalation risk for nano-forms and EU restrictions
