Quaternium 73

1. Definition Quaternium 73:

Quaternium-73 is a quaternary ammonium compound commonly used in cosmetics as a conditioning agent and surfactant. It is often found in hair care products such as shampoos, conditioners, and styling products.

2. Use:

Quaternium-73 is primarily used in cosmetics for its conditioning properties. It helps to improve the texture and appearance of hair by reducing static, increasing manageability, and enhancing shine. Additionally, it can also act as a surfactant, helping to cleanse the hair and scalp by attracting dirt and oil particles so they can be easily rinsed away.

3. Usage Quaternium 73:

Quaternium-73 is typically found in hair care products at concentrations ranging from 0.1% to 5%. It is safe for use in rinse-off products such as shampoos and conditioners, but caution should be taken when using leave-in products containing this ingredient, as prolonged exposure to the skin may cause irritation. It is recommended to follow the manufacturer's instructions and perform a patch test before using products containing Quaternium-73 to ensure compatibility with your skin and hair.
