POLYESTER-21

Description

Polyester-21 is a synthetic polymer utilized in various skincare and haircare formulations. This ingredient functions primarily as a film-forming agent and emulsion stabilizer, providing enhanced texture and stability to cosmetic products. Its unique molecular structure allows it to form a protective barrier on the skin or hair surface, helping to lock in moisture and shield against environmental stressors.

In skincare applications, Polyester-21 contributes to the smooth application and even distribution of active ingredients, improving product efficacy. It aids in creating lightweight, non-greasy textures that are particularly beneficial in leave-on products such as serums and moisturizers. The film-forming properties of Polyester-21 can help reduce transepidermal water loss, potentially leading to improved skin hydration.

For haircare formulations, Polyester-21 assists in enhancing the manageability and shine of hair strands. It can provide a temporary smoothing effect, reducing frizz and improving overall hair appearance. The ingredient's ability to form a flexible film also contributes to increased hold in styling products without causing stiffness or flaking.

Polyester-21 is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations at recommended concentrations.
