2-ACRYLAMIDO-2-METHYLPROPANE SULFONIC ACID

Description

2-Acrylamido-2-methylpropane sulfonic acid (AMPS) is a versatile synthetic ingredient used in various skincare and haircare formulations. This water-soluble polymer possesses exceptional moisture-retention properties, making it highly effective in hydrating products. AMPS forms a protective film on the skin and hair, helping to lock in moisture and improve overall texture.

In skincare, AMPS acts as a humectant and film-former, enhancing product stability and improving the spread of active ingredients. Its ability to form a uniform, thin layer on the skin surface contributes to a smooth, non-greasy feel in lotions and creams. AMPS also exhibits excellent compatibility with a wide range of cosmetic ingredients, including electrolytes and surfactants.

For haircare applications, AMPS provides conditioning benefits and helps to reduce static electricity. It can improve the manageability of hair, particularly in leave-in treatments and styling products. The polymer's resistance to hard water makes it particularly useful in formulations designed to protect hair from mineral build-up.

AMPS is generally well-tolerated and suitable for use in a variety of skin and hair types. Its stability across a wide pH range further enhances its versatility in product formulation.
