How to Increase Shampoo pH from 3

To increase the pH of a shampoo formulation from 3, you can use an alkaline substance. Sodium Hydroxide is commonly used in cosmetic formulations to raise the pH.

• Sodium Hydroxide (also known as Caustic Soda) is a white, easily moistened solid that dissolves in water.
• It is used to increase the alkalinity (raise the pH) of cosmetic products.
• Usage Rate: Typically used at a rate of 0.1-5%. Do not exceed 5%.
• Mixing Method: Add it during the process where pH adjustment is needed.

Always adjust pH gradually and check the pH level frequently to reach your desired range.
