DESCRIPTION
SYMSAVE H

SymSave® H is a multi-purpose cosmetic ingredient that acts as an antioxidant, preservative booster and soothing agent. It increases the effectiveness of various preservatives such as phenoxyethanol, chlorphenesin, organic acids and formaldehyde donors (DMDM hydantoin, imidazolidinyl urea). It is considered FEMA/GRAS, meaning it is safe for use in products applied near the mouth.

Practical formulation guide
Usage level: 0.5–1.0%; typical examples: ✓ 0.5% phenoxyethanol + 0.5% SymSave® H ✓ 0.1% DMDM hydantoin + 0.5% SymSave® H ✓ 0.3% sodium benzoate + 0.8% SymSave® H ✓ 0.3% phenoxyethanol + 0.3% SymSave® H + 0.3% potassium sorbate or 0.4% potassium benzoate ✓ 0.2% potassium sorbate + 0.8% SymSave® H
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: Formulation guide: • To dissolve SymSave® H in water, add with stirring. • Heating to 60 °C/140 °F speeds up dissolution. • SymSave® H is also soluble in phenoxyethanol, glycerin, ethanol and glycols such as pentylene glycol and propylene glycol. • Glycerin or glycols dissolved in water first help SymSave® H dissolve cold. • When making emulsions, it is best to add SymSave® H to the water phase.
  • 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: Store in tightly closed containers; do not store in heat or direct sunlight.
Precautions: Wear gloves.
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.
