Method for the selective extraction of polyethylene terephthalate (PET) from a complex mixture of thermoplastics and thermosets. The present invention relates to a method for extracting polyethylene terephthalate (PET) from a solid material containing it in a mixture with one or more auxiliary thermoplastic materials and / or one or more thermoset materials, optionally at least one metal. The method comprises at least the steps of: - Contacting said solid material with a solvent selected from dimethyl isosorbide, benzyl acetate, and mixtures thereof in a reactor; - Selectively solubilizing said polyethylene terephthalate by heating the mixture formed from said material and said solvent, under stirring, at a temperature ranging from 185°C to 220°C; - Isolating said solvent containing the solubilized polyethylene terephthalate (PET) from said mixture; - Precipitating said polyethylene terephthalate in said isolated solvent.and- Recover the polyethylene terephthalate precipitate. Figure for the summary: None,

This application relates to the field of personal care products, disclosing a no-rinse herbal skin-care bath liquid and its preparation method. The bath liquid raw materials include a herbal-eutectic precursor matrix, an aqueous solution of sodium cocoyl apple amino acid, deionized water, and a pH adjuster. The matrix is ​​made of betaine, matrine, dipotassium glycyrrhizate, and dimethyl isosorbide. The preparation method includes mixing the components and then adjusting the pH under negative pressure. During this process, the pH value and viscosity of the system are monitored in real time. When the instantaneous viscosity increases by a set proportion, the dropping rate of the acid adjuster is reduced and a high-speed shearing is initiated simultaneously. This invention utilizes the hydrogen bonding between specific matrix components to inhibit the crystallization and precipitation of herbal ingredients after water evaporation, improving the stickiness of residues. Simultaneously, by combining rheological feedback and negative pressure shearing technology, it alleviates the foaming and stratification problems of amino acid surfactant systems during the acid reduction adjustment process.
