Polyhydroxy acid-polyhydroxyalkanoate dual anti-hard water dilution-triggered coacervate deposition type bath composition and its preparation method and use

Abstract

The application discloses a polyhydroxy acid-polyhydroxyaliphatic ester dual-state hard water-resistant dilution-triggered coacervate deposition type bath composition, a preparation method and application thereof, and belongs to the field of rinse-off personal cleansing care. The application effectively chelates metal ions in a hard water bathing environment through a polyhydroxy acid component, thereby guaranteeing excellent foaming capacity and foam stability of the system. During the dilution and rinsing stage of bathing, electrostatic association occurs between a cationic deposition polymer and an anionic charge donor, and a coacervate complex phase is rapidly formed and separated from a continuous water phase. The complex phase can efficiently physically wrap and trap solid particles, thereby significantly improving the post-rinsing residence of functional particles on the surface of the skin. Meanwhile, the composition has excellent long-term storage stability, effectively overcomes the problem of particle sedimentation and stratification, and the rinsing and drainage are smooth, thereby comprehensively optimizing the bathing care experience.
