Preservative for 120ml Toner

Based on the previous recommendation and product information, Phenoxyethanol SA (eq. Optiphen Plus) is a suitable broad-spectrum preservative for your toner formulation.

For a closed container product like toner, the recommended usage rate is typically 1.0%.

To calculate the amount needed for 120ml of toner:

• 1.0% of 120ml = (1.0 / 100) * 120 ml = 1.2 ml

So, you would need approximately 1.2 ml of Phenoxyethanol SA for 120ml of toner.

Mixing Instructions:

• Add Phenoxyethanol SA in the final step of your formulation.
• Ensure the temperature of the toner base is below 60°C.
• The pH of the final product should be between 2.0 and 6.0 for optimal effectiveness.
