DESCRIPTION
Gellan gum: forms jellies and gels, and stabilizes formulas. Used in jelly soaps, gels and emulsions.
Practical formulation guide
Usage level: Guideline range: 0.2–1 % for gums and carbomers; depending on the desired viscosity.
How to use and incorporate: Gums and celluloses (xanthan, guar, hydroxyethylcellulose, alginate): premix with glycerin or a polyol to prevent lumps and disperse in water with stirring; let hydrate 20–60 minutes. Carbomers and acrylates: sprinkle over stirred water, hydrate and neutralize with triethanolamine or sodium hydroxide to pH 5.5–7 to form the gel.
Formulation tips:
- Carbomers lose viscosity with electrolytes and at acidic pH; add salts, extracts and acidic actives carefully.
- To suspend particles (exfoliants, beads), a thickener with yield value is required, such as carbomer or xanthan gum.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Compatible with most humectants, water-soluble actives and preservatives. Check compatibility with surfactants and salts.
Storage: Store in a tightly closed container, in a cool, dry place, protected from light.
Precautions: Avoid inhaling the powder. Powder spills with water are very slippery.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
