Final answer:
The substances used to neutralize acids or raise the pH of many hair products are Alkanolamines. Alkanolamines are organic compounds that contain both an amine group and an alcohol group.
Step-by-step explanation:
The substances used to neutralize acids or raise the pH of many hair products are Alkanolamines. Alkanolamines are organic compounds that contain both an amine group and an alcohol group. When added to hair products, they react with acids to form neutral salts, thereby raising the pH.
For example, in alkaline drain cleaners, sodium hydroxide is commonly used as a strong base to dissolve hair and greases. Sodium hydroxide is an alkanolamine compound that reacts with acids to neutralize them and raise the pH.
Other examples of alkanolamines used in hair products include ethanolamine and triethanolamine. These compounds help adjust the pH and improve the performance of the products.
