ADJUSTING pH
To lower the pH of your product : A solution is made up of 50% citric acid and 50% distilled water. ( example: 50g of citric acid to 50g of water )
To increase pH of your product: A solution is made up of 10% Sodium Hydroxide and 90% water. ( example: 10g of water to 90g of water )
ALWAYS PLACE SODIUM HYDROXIDE POWDER INTO WATER AND NOT THE OTHER WAY AROUND!!!!!!!
Test the pH of your product with pH strips ( or a hanna pH meter ) and adjust up or down if necessary using a pipette.
