Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Dipropylene Glycol
- Solvent for essential oils; better humectancy than PEG
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Diglycerin
- Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.
- Maltitol
- Sugar alcohol humectant and emollient; tacky at high levels, limit load.
- Polyglyceryl-10 Myristate
- Mild emulsifier and emollient; 1-3%, suitable for O/W systems
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Triethylhexanoin
- Light ester for non-greasy feel and fragrance; low allergenicity, high levels can act as solvent
- Diphenyl Dimethicone
- Silicone for emollience and antistatic; used in hair and skin care, check compatibility with other silicones
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Hydrolyzed Hyaluronic Acid
- Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.
- Hydrolyzed Elastin
- Hydrolyzed elastin, moisturizer; MW determines penetration, large MW surface conditioning.
- Citrus Unshiu Peel Extract
- Citrus peel extract providing fragrance
- Hydrolyzed Collagen
- Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies
- Eriobotrya Japonica Leaf Extract
- Loquat leaf extract; rich in flavonoids, high batch-to-batch variability
- Origanum Majorana Leaf Extract
- Oregano leaf extract with thymol/carvacrol; anti-sebum claims, essential oil allergen risk.
- Glycine Soja Seed Extract
- Soybean extract for skin conditioning; low allergen risk, monitor batch protein variability.
- Lavandula Stoechas Extract
- French lavender extract rich in linalool; offers natural soothing aroma; requires allergen labeling when used as fragrance.
- Sodium Bicarbonate
- Sodium bicarbonate; buffer and deodorant; alkaline at high pH, potential irritation, control dosage
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Platinum Powder
- Functional powder for skin conditioning; very high cost, trace levels; verify regulatory status.
- Squalane
- Emollient from plants or synthetic; light texture
- Cerebrosides
- Not decoded yet
