POLYBUTYLENE SUCCINATE.

Optional CAS 25777-14-4 / SKIN CONDITIONING

Polybutylene Succinate is a biodegradable aliphatic polyester and thermoplastic polymer. In skincare, it primarily functions as a formulation aid, enhancing texture, stability, and penetration of cosmetic products rather than providing direct biological benefits to the skin.

Film-forming agent Texture enhancer Binding agent Formula stabilizer

Science

As a thermoplastic polymer, Polybutylene Succinate operates within cosmetic formulations by forming films, binding ingredients, or modifying texture. Its action is focused on improving the physical properties of the product, such as spreadability and stability, facilitating optimal delivery without a direct biological impact on skin cells.

Stability

This polymer exhibits robust thermal stability but can undergo degradation into lower molecular weight compounds upon exposure to water. The rate of this hydrolysis accelerates with increasing temperature.

Conflicts

  • Poor compatibility with polyhydroxybutyrate-co-valerate (PHBV).
  • Limited miscibility with starch unless properly plasticized and chemically modified.
