Polyquaternium 12

1. Definition Polyquaternium 12:

Polyquaternium 12 is a type of quaternary ammonium compound that is commonly used in cosmetics as a conditioning agent and film-forming agent. It is a polymer that is positively charged, which allows it to bond with negatively charged particles in the hair and skin, providing conditioning and anti-static properties.

2. Use:

Polyquaternium 12 is primarily used in hair care products such as shampoos, conditioners, and styling products. It helps to improve the texture and manageability of the hair, making it easier to comb and style. It also helps to reduce frizz and static electricity, leaving the hair looking smooth and shiny.

3. Usage Polyquaternium 12:

When using products containing Polyquaternium 12, it is important to follow the instructions provided on the packaging. Typically, a small amount of the product is applied to damp hair and massaged in before rinsing thoroughly. It is recommended to avoid getting the product in the eyes, as it may cause irritation. If any adverse reactions occur, such as redness or itching, the product should be discontinued immediately.
