- Calcium Chloride
- Cross-linker and viscosity controller for gels; astringent at high levels, check skin tolerance
- Ceratonia Siliqua Gum
- Locust bean gum thickener/emulsifier; viscous at high levels, check batch consistency.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Polyglyceryl-4 Caprate
- Non-ionic emulsifier; biodegradable, compatibility with anionics requires check.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Chondrus Crispus Powder
- Seaweed powder for gentle physical exfoliation; absorbs water; for scrubs and care, no chemical irritation.

- Citrus Aurantium Bergamia Fruit Oil
- Bergamot essential oil, natural fragrance and photosensitizer; limit daytime use or use FCF grade
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Ceramide NP
