Ingredients explained
- Isododecane
- Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.
- Polyethylene
- Plastic polymer particles for abrasion or film; check EU ban on microplastics in rinse-off products, flush-off only
- Cyclopentasiloxane
- Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.
- Trimethylsiloxysilicate
- Silicate powder, oil-absorbing emollient; insoluble, high levels feel powdery.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Octyldodecanol
- Light emollient/emulsifier at 1-5%; low comedogenic, non-greasy feel, broadly compatible, sensitive-skin friendly.
- Trimethylsiloxyphenyl Dimethicone
- Aryl silicone for gloss and slip; non-comedogenic but poor biodegradability; check compatibility.
- Disteardimonium Hectorite
- Inorganic ionic clay thickener at 0.25-1%; water/oil/solvent systems, rheology control, avoid strong acids, may affect active release.
- Hydrogenated Polyisobutene
- Hydrogenated polyisobutene; petroleum-derived lubricant forming breathable film; high purity, low irritation/comedogenicity.
- Lecithin
- Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Sorbitan Sesquioleate
- Non-ionic emulsifier for O/W or W/O systems; moderate emulsification power, often used with co-emulsifiers
- Barium Sulfate
- Inert mineral filler and thickener; not absorbed by skin, avoid dust inhalation in powder processes
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Carmine
- Natural red colorant (cochineal); may trigger reactions in those with insect protein allergy
- Ultramarines
- Inorganic colorant for blue/purple shades; contains trace selenates, requires compliance with heavy metal limits.
- Black 2 [Nano
- Not decoded yet
- Iron Oxides (Ci 77491
- Not decoded yet
- Ci 77492
- Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
- Ci 77499)]
