    摘要： The invention relates to a photostable cosmetic or pharmaceutical light screening composition containing a dibenzoyl methane UV-A screening agent and a p-methoxycinnamate UV-B screening agent, one of said agents being incorporated into a polymer latex; and, optionally, other conventional UV-A and UV-B screening agents.
    Furthermore the invention relates to a method of photostabilizing dibenzoyl methane UV-A screening agents and p-methoxycinnamate UV-B screening agents when used together, by incorporating one of these agents into a polymer latex.

    摘要： The invention relates to a process for preparing a highly loaded adsorbent, which process comprises the steps of

    a) extracting an oil from an oil crude product by means of supercritical fluid extraction thus, obtaining a loaded supercritical fluid (SCF);
    b) expanding the loaded SCF of step a) followed by heating to obtain a liquid phase and a in-loading reduced SCF phase;
    c) optionally decreasing the pressure and/ or raising the temperature of the SCF phase of step b) to conditions of adsorption;
    d) introducing the SCF of step b) or step c) into a fixed bed adsorber to obtain an adsorbent loaded with the purified oil and pure SCF;
    e) feeding the liquid phase of step b) as a reflux to the extraction device of step a) ;
    f) compressing and tempering the pure SCF of step d) to extraction conditions;
    g) recycling the pure SCF to the extraction device of step a).

    The invention further comprises a process for purifying an oil from an oil crude product by desorbing the adsorbed oil.
    The invention further comprises 16 A process for purifying an oil, optionally combined with a process for preparing a highly loaded adsorbent, which process comprises the steps of:

    A) extracting a fraction containing the oil together with high volatile components from a crude synthetic or natural oil mixture by means of supercritical fluid extraction (SFE) thus, obtaining a loaded supercritical fluid (SCF) and a raffinate containing the low volatile components of the crude product;
    B) expanding the loaded SCF of step A) followed by heating to obtain a liquid phase containing the oil and high volatile components and an unloaded gas phase (step B-1) or to obtain an in-loading reduced SCF and a liquid phase (step B-2);
    C) optionally decreasing the pressure and/ or raising the temperature of the in-loading reduced SCF phase of step B-2) to conditions of adsorption;
    D) optionally introducing the in-loading reduced SCF of step B-2) or of step C) into a fixed bed adsorber to obtain an unloaded gas phase and an adsorbent loaded with oil;
    E) collecting the unloaded gas phase of step B-1) or of step D) in a vessel and controlling the content of the gas components;
    F) optionally feeding pure gas into the vessel of step E) to guarantee the same gas composition over the whole process time;
    G) feeding part of the liquid phase of step B-1) or all of the liquid phase of step B-2) at the same temperature and pressure of the column as a reflux to the extraction device of step A);
    H) pressurizing the gas phase of step E) or of step F) followed by cooling to separation conditions;
    I) recycling the SCF of step H to the extraction device of step A);
    J) optionally feeding the liquid phase of step B-1) to a second extraction device;
    K) extracting a fraction of high volatile components from the extract of step B-1) by means of SFE thus obtaining a loaded SCF and the pure oil as raffinate;
    L) treating the reflux and the SCF as described in the steps B-1 - I);
    M) collecting the oil at the bottom of the column as a raffinate.
