    The difference between turbidity point and high turbidity point SH412 fully automatic turbidity point meter and high turbidity point refers to the phenomenon of solubility leading to turbidity; However, the source of the cloud point and the observed conditions are very different - both affect the formulation.
    : Many substances, such as esters, have a wide range of molecular weights (C 8 -C 22).
    these different parts are usually cured at different temperatures.
    as the temperature decreases, the material may become solid, the turbidity may remain, or the insoluble material may fall to the bottom in the form of sediment.
    , the SH412 fully automatic turbidity point meter will disappear.
    aware of this is important for formulators, as the higher molecular weight materials present in the SH412 fully automatic turbidity point analyzer material are likely to improve the feel of the product, such as the feel of the product, in a given formulation.
    if the lower turbidity in the raw material is removed through cold filtering, the benefits they lose will disappear.
    to prevent this loss, the appearance specification of such materials should specify different temperatures - one above the cloud point and the other at the cloud point.
    Therefore, it is not uncommon for this condition to have transparent liquids specified for material specifications at 50 and cloudy liquids at high or anti-turbidity points of 10 ö C: this phenomenon occurs in surfactants, mainly acetyloxylized surfactants.
    different from the cloud point, which is observed in aqueous solutions.
    SH412 fully automatic surfactant turbidity point assay has the surface activity agent of polyoxyethylene chain to hydrate or "absorb water" affinity.
    hydrate improves the solubility of these materials.
    when the solution is heated, the movement of the polyoxid ole chain impairs the ability to maintain hydrated water, which results in a reduced solubility of the material.
    at a certain temperature, depending on the molecule, SH412 automatic surfactant turbidity point determination instrument surface active agent becomes cloudy.
    the material is cooled, the material dissolves again and transparency is regained.
    this feature is important for cosmetic formulat designers.
    , for example, emulsions made with non-ion surfactants with a high turbidity point of 50 oC.
    stability of the emulsion may be good below the inverse cloud point, but it may break when the temperature is reached.
    this is due to the loss of solubility at high temperatures.
    high turbidity point is also used as a way to obtain thermal activation, as the surfactant becomes more substantial to the hair and skin when it is above its high turbidity point due to its lower solubility in water.
    these two different physical characteristics are important attributes of the products used in personal care applications and must be considered part of product stability for any new product.
    is not uncommon for a material to have both high and high turbidity points.
    when the temperature drops, the material becomes cloudy and clears when heated (SH412 fully automatic surfactant turbidity point detector turbidity point).
    they can also have a turbidity point, which is foggy when placed in an aqueous solution and heated.
