How It Works

Key Benefits

• Helps buffer and stabilise the pH of a formula
• Mild antimicrobial support alongside a preservative system
• Easy to dissolve in warm water
• 100g pack suits small-batch work

Ingredients

Boric Acid (INCI). Single ingredient.

How to Use

• Boric acid is a restricted ingredient in cosmetics in many countries. Check the permitted level and any labelling rules where you sell before you use it.
• It should not be used in products for children under 3, or on broken or irritated skin.
• Dissolve it in warm water, then add it to the water phase of your formula.
• Harmful if swallowed. For cosmetic formulation use only. Keep out of reach of children. Avoid eyes and avoid inhaling the powder.
• Storage: keep tightly closed in a cool, dry place.

Always test your formulation and follow the cosmetic regulations in your country.
