Practical formulation guide
Usage level: Suggested usage level: 0.5–1 % of the total formulation
Set it according to the technical data sheet, pH and formula type; there is no universal preservative dosage.
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: Incorporate below 40 °C/104 °F at the end of the process. Always check the final pH of the product. Catalog note: this data sheet corresponds to the phenoxyethanol preservative; Symsave H is a different product and is handled as a separate reference.
- 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: Cool, dry place, protected from light and moisture. Cosmetic grade / raw material for formulation.
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.
