    • The invention relates to a method which comprises synthesising bifunctional compounds then chiral compounds from the bifunctional compounds, also to synthesising supports comprising these chiral compounds, and the use of these supports for preparing or separating enantiomers, or for asymmetric synthesis. The invention also relates to bifunctional compounds, their use as a source of functionalised polymers, and to the chiral compounds, also to the use of these chiral compounds in a chiral support in the form of a three-dimensional network or for separating or preparing enantiomers, principally for analytical or preparative chromatography, and in a support for the production of chiral molecules by asymmetric synthesis.

    • Water-soluble quaternary ammonium cellulosic derivatives of controlled charge density are disclosed. These derivatives are useful in cosmetic preparations, such as hair and skin formulations, for example hair conditioners. These quaternized cellulosic derivatives are useful as thickeners, conditioners, film formers, fixatives, emulsifiers, or additives in hair or skin formulations to improve combing, manageability, body, curl retention, moisture resistance, and binding of ingredients to keratin. Compared to existing agents, these compounds have improved temperature stability, improved interactions with surfactants (such as in shampoos), improved binding to keratin, improved mechanical properties, and can mend split ends on hair. A major advantage of these compounds is that they may be applied to hair directly from an aqueous solution, and do not require a volatile organic compound solvent as carrier. Alternatively, smaller amounts of VOC's may be used than is the case in current products, to improve drying times for the formulations. The compounds are also useful as antistatic agents, bactericides, flocculating agents, and as drug binding or drug delivery agents.
    • 公开了具有受控电荷密度的水溶性季铵纤维素衍生物。 这些衍生物可用于化妆品制剂,例如头发和皮肤制剂,例如头发调理剂。 这些季铵化的纤维素衍生物可用作毛发或皮肤制剂中的增稠剂,调理剂,成膜剂,固定剂,乳化剂或添加剂,以改善组合,可管理性,身体,卷曲保留性,耐湿性和成分与角蛋白的结合。 与现有的试剂相比,这些化合物具有改善的温度稳定性,改善与表面活性剂的相互作用(如洗发剂),改善的与角蛋白的结合,改进的机械性能,以及修补头发上的分叉端。 这些化合物的主要优点是它们可以直接从水溶液中施用于毛发,并且不需要挥发性有机化合物溶剂作为载体。 或者,可以使用比当前产品更小量的VOC,以改善制剂的干燥时间。 这些化合物也可用作抗静电剂,杀菌剂,絮凝剂,以及药物结合或药物递送剂。
