A flexible, highly efficient method for the preparation of homochiral oxazaphospholidine-boranes
摘要:
An efficient and operationally simple procedure for the synthesis of 2-substituted 3,4-dimethyl-5-phenyloxazaphospholidine derivatives has been developed. This new method permits the large scale preparation of a range of electronically and sterically differentiated homochiral monophosphine precursors.

La présente invention a pour objet l'utilisation pour le décapage de la couleur artificielle des fibres kératiniques d'une composition comprenant au moins une phosphine ou l'un de ses sels d'addition avec un acide à titre d'agent réducteur majoritaire, le procédé de décapage de la couleur artificielle des fibres kératiniques mettant en oeuvre cette composition et un dispositif à plusieurs compartiments destiné à la teinture puis au décapage de la couleur artificielle des fibres kératiniques.
La présente invention fournit un produit de décapage de la couleur artificielle des fibres kératiniques teintes avec une large palette de colorants d'oxydation et / ou de colorants directs, qui n'induit pas d'éclaircissement de la base naturelle des fibres kératiniques, qui soit plus pratique d'utilisation et qui limite la sensibilisation des fibres kératiniques.

The present invention addresses the problem of providing an eggshell membrane solubilization method that is capable of solving the problems associated with carrying out treatment using acids and alkalis, or problems associated with the processing methods of the conventional art that use proteases; in other words, an eggshell membrane solubilization method that is capable of solving at least one of the following problems: (1) the need for pretreatment such as pulverization, sonication or boiling; (2) the need for prolonged treatment; and (3) a low decomposition rate (approximately 20%). Eggshell membranes are efficiently solubilized by using a protease in combination with a reducing agent.

The- present invention relates to a cosmetic -composition for keratin fibers, comprising: (a) at least one alkoxysilane; (b) at least one silicone; and (c) at least one selected from the group consisting of thiol-based reducing agents, non thiol-based reducing agents, alkaline metal hydroxides and alkaline earth metal hydroxides. The present invention is useful because the present invention can reduce the damage to keratin fibers due to permanent reshaping or deforming of the keratin fibers, and provide the keratin fibers with good cosmetic properties such as soft or supple appearance and feel to the touch which can last for a long time even after shampooing, while providing the keratin fibers with good permanent reshaping or deforming effects
