摘要:
The present invention relates to novel amphoteric polysaccharide compounds containing aldehyde function(s) corresponding to the formula (I): P—(O—(Y)p-CAT)m in which: P represents a polysaccharide chain, the said chain hearing one or more aldehyde functions and optionally one or more groups —COOV, this group possibly being obtained during the oxidation of certain carbon atoms of a saccharide unit, Y represents a linear or branched, saturated or unsaturated, optionally hydroxylated divalent C1-C8 divalent hydrocarbon-based group comprising at least one ether and/or amine function in the hydrocarbon-based chain, or a group —Si(R)2—[O—Si(R)2]q-Z-; p is O or 1, and CAT represents an ammonium group or a cationic polymer chain obtained by grafting and polymerization of ethylenic monomers bearing an ammonium function. The invention also relates to their use in cosmetics and to compositions comprising them.

摘要:
A fluorohydrocarbon compound of formula RF—C2H4—O—CO—RH, in which RF is a perfluorinated alkyl group and RH is an alkyl group, in and/or for the preparation of a stable emulsion containing at least one fatty phase and one aqueous phase. The invention also relates to the use of the same compound as a stabilizing agent for an emulsion containing at least one fatty phase and one aqueous phase. Another subject of the invention is the use of such a compound as an essential component of the fatty phase of an emulsion and emulsions containing such a fatty phase. Another subject of the invention is a composition comprising such an emulsion.

摘要:
A dry offset printing process using a printing apparatus including a) at least one inker block, each block inking a relief plate corresponding to one color of the final motif to be reproduced on an object and including an inker and a succession of transfer rollers, and b) a central blanket which can be placed into contact with the object to be decorated. An ink of suitable tackiness is selected, and the temperature of the ink is regulated in the inker to a predetermined temperature between 15.degree. and 30.degree. C.
摘要:
According to the invention, the surface of a blank to be shaped into a product is decorated by marking on a test blank a plurality of reference points distributed over the entire surface of the test blank which will be affected by the shaping. The test blank is then shaped into a test product and the positions of the reference points are determined. A block of decoration to be obtained on the product is formed, and the positions of the reference points on the test product are located on the block. The decoration is then converted into a plurality of pixels of each inking color, and the position of each pixel with respect to the reference points on the test product is located. A corresponding pixel position with respect to the reference points on the test blank is also determined, and a film is prepared by printing the film with each pixel of the decoration reproduced in a location corresponding to the corresponding location on the test blank. At least one blank is then decorated with the film.
