摘要:
A variety of products are obtained from modified guar protein extracts, for example, cosmetic or pharmacological or plant protective compositions or domestic care agents containing such products; these are particularly suitable for treating and/or modifying and/or coating the skin, hair, hard and textile surfaces and, notably, plant leaf surfaces.
摘要:
Surface treating and/or modifying compositions, for example cosmetic or pharmaceutical or plant protective compositions or domestic care compositions contain a guar protein extract, or derivative thereof, such guar protein extract containing at least 65% by weight of proteins and are particularly suitable as surface treating and/or modifying agents, wherein these surfaces are, for example, the skin, hairs, domestic care and textile surfaces and plant leaf surfaces.

The invention relates to a composition for the treatment of articles made of textile fibres which is intended to be used for washing and/or rinsing, drying in a tumble dryer or ironing articles made of textile fibres comprising a dendritic polymer (in particular a hyperbranched polyamide). The invention also relates to the use, in a composition for the treatment of articles made of textile fibres which is intended to be used for washing and/or rinsing, drying in a tumble dryer or ironing articles made of textile fibres, of a dendritic polymer (in particular hyperbranched polyamide) as antiwrinkling agent or ease-of-ironing agent.
摘要:
The invention relates to thermoplastic compositions comprising a thermoplastic polyamide matrix and at least one additive which modifies the interaction between the matrix and an agent. The purpose of the invention is to provide an additive which modifies the interaction between a copolyamide-type thermoplastic copolyamide matrix and at least one agent. The aforementioned additive, which comprises at least one hyperbranched functionalised polymer, is not compatible with the matrix. Moreover, said additive can be used for the controlled modification of the interaction between the thermoplastic copolyamide and an internal or external chemical agent. Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7% in relation to a sample composition which comprises matrix M but does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a determined protocol P. The invention is suitable for use in moulding, injection moulding, injection/blow moulding, extrusion/blow moulding, extrusion or spinning.

The invention relates to hyperbranched copolyamides (HBPAs), to their production and to their use as additives, in particular as melt viscosity modifiers in thermoplastic polymer compositions.This copolyamide is obtained by a reaction between a monomer (I): A—R—Bf with A and B=polymerization functions of a 1st and 2nd type, respectively, which are capable of reacting with each other, R=hydrocarbon-based species and f=total number of B per monomer (preferably 2≦f≦10); and a monomer (II) A′—R′—B′ or the corresponding lactams, with A′, B′ and R′ having the same definition as that given above for A, B and R, respectively. This HBPA has a I/II molar ratio such that 0.125≦I/II≦2. One of the species R or R′ of (I) or (II) is aliphatic, cycloaliphatic or arylaliphatic.For example: A=NH2 and B=COOH or A=COOH and B=NH2 with F=2.A′=NH2 and B′=COOH or A′=COOH and B′=NH2.A—R—B2, e.g.: 5-aminoisophthalic acid or 3,5-diaminobenzoic acid and A′—R′—B′=ε-caprolactam.The yarns, fibres, films and moulded parts obtained using polymer compositions (e.g. PA) to which are added HBPA according to the invention are also included in this invention.

摘要:
Unwanted natural and synthetic organic impurities are removed from liquid media contaminated therewith, e.g., liquids and beverages intended for human consumption, or industrial/wastewaters, by introducing into such media a thus effective amount of an optionally modified/insoluble cationic vegetable gum containing one or more cationic or cationizable substituents, maintaining the cationic vegetable gum in such liquid medium until the organic impurities are sorbed thereon, and thence recovering the vegetable gum/sorbed impurities therefrom, whereby purifying the liquid medium.
摘要:
Water-soluble or water-dispersible matrix, made of a polysaccharide modified under an electron beam with an organosilicon compound chosen from organosilanes and/or polyorganosiloxanes having at least one functional group capable of reacting and/or interacting with said polysaccharide. Use of the matrix as stabilizing agent in the preparation of simple emulsions, in particular of the water-in-oil type, or multiple emulsions, in particular of the water-in-oil-in-water type.
摘要:
The invention related to the use of oligo-apiogalacturonan compounds, particularly extracted from aquatic plants of the Lemna or Zostera Genus, as an agent for stimulating the defence and resistance reactions in a plant, in particular an ornamental plant or a plant of agricultural interest, against biotic an/or abiotic stresses. The invention further relates to a method for stimulating the natural defence reactions of a plant or a portion or a plant against biotic and/or abiotic stresses that includes applying at least one oligo-apiogalacturonan compound in a liquid or solid composition on said plant or a portion of a plant or in the environment of said plant.
