- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Centella Asiatica Extract
- Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.
- Amylopectin
- Polysaccharide as binder and viscosity controller; starch-derived, no significant skin irritation
- Dextrin
- Polymer thickener and binder from starch fermentation; biodegradable, hygroscopic, may affect powder flow
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Melia Azadirachta Leaf Extract
- Plant extract, 0.1–1%; has antibacterial properties, allergy testing advised.
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Sodium Nitrate
- Milding agent mainly in oral care (mouthwash/toothpaste); rare in cosmetics.
- Glyoxal
- Prohibited allergen; max 0.1% limit; shall not be placed on market in concentrations >= 0.1%.
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
