Practical formulation guide
Usage level: Use within the data sheet range and without exceeding the regulatory limit for each component.
How to use and incorporate: Add according to its maximum temperature, usually during cool-down (below 40–45 °C/104–113 °F), dissolved or premixed in the phase indicated by the data sheet. Check that the final pH of the formula is within its effective range.
Formulation tips:
- Preservation depends on the whole formula: validate the system with a microbial challenge test.
- Organic acids (benzoic, sorbic, dehydroacetic) are only effective at acidic pH (approximately ≤ 5.5). Extracts, hydrosols, proteins and starches increase the demand for preservative.
- Follow good manufacturing practices: purified water, sanitized utensils and clean packaging.
Compatibility: Check compatibility with nonionic surfactants, proteins and some polymers, which may reduce its effectiveness.
Storage: Original container tightly closed, protected from light and heat.
Precautions: Respect the maximum permitted concentration. Wear gloves and safety glasses; avoid contact with eyes and skin in concentrated form. See the Safety Data Sheet.
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.
