SOY PROTEIN PHTHALATE functions primarily as a film-forming polymer, imparting an immediate textural improvement, alongside roles as an emollient and humectant in formulations. Its inclusion in skincare is highly contentious, however, due to its classification as a suspected endocrine disruptor and a phthalate.

Science

Mechanism of Action

This compound operates as a film-forming polymer, delivering an instant, perceptible effect on the skin's surface. Within cosmetic systems, it serves multiple functions, including acting as a binding agent, an emollient for skin softening, a humectant for moisture retention, and a skin conditioning agent. Furthermore, it contributes to formulation integrity by stabilizing emulsions and modulating viscosity.

SOY PROTEIN PHTHALATE is classified as a suspected endocrine disruptor and a phthalate, substances that are largely restricted in cosmetic formulations within the European Union. Chronic exposure to phthalates is associated with potential negative impacts on the endocrine system, organ function, reproductive health, and child development. While the Cosmetic Ingredient Review (CIR) Expert Panel deemed general soy proteins and peptides safe in 2015, this specific phthalate-modified soy protein has not undergone an independent safety review by the CIR.
