摘要:
The invention concerns novel polyol-glycoside compositions for topical use. The invention is characterized in that said compositions contain an efficient amount of polyol-glycoside obtained by acetalization of a polyol of formula (I), wherein n is an integer equal to 2, 3 or 4; or of formula (II), wherein m is an integer equal to 2 or 3, with a reducing sugar. The invention is applicable in cosmetics, dermopharmaceutics, pharmaceutics, textile industry.
摘要:
The invention concerns a herbicide composition comprising N-(phosphonomethyl)glycine or one of its salts, at least a compound of formula (I): RO—(X)p wherein: p represents a decimal number between 1 and 5; X represents the xylose radical; and R represents a linear or branched, saturated or unsaturated alkyl radical comprising 6 to 18 carbon atoms, a dispersing medium both for the active principle and the compound of formula (I), optionally, one or several surfactants and optionally one or several inert adjuvants. The invention also concerns a phytosanitary method using said composition and the use of a product of formula (I), to prepare a herbicide composition.
摘要:
A method of improving the solubility of a defoaming non-ionic compound in an alkaline aqueous medium includes adding to the aqueous medium a defoaming compound an effective quantity of a compound having the formula: ROZn in which R represents a 2-ethyl hexyl radical, Z is a sugar residue, and n is between 1.1 and 2.
摘要:
A foaming composition containing one or more fluorinated surfactants and or more alkylpolyglycoside hemisulphosuccinate surfactants of formula (I) is described, ##STR1## wherein R is a straight or branched chain alkyl radical with 6-18 carbon atoms, S is a sugar residue, one of R.sub.1, and R.sub.2 is a SO.sub.3 M group, and the other a hydrogen atom, M is an alkali metal, preferably sodium, X is an integer of 1 to 10, preferably of 1 to 4. The foaming composition is useful as a fire-extinguishing foam.
摘要:
Perfluoroalkylated amphiphilic phosphorus compounds, corresponding to the formulae: ##STR1## wherein V is O or S; R.sup.1, R.sup.2 and R.sup.3 are H or substituted or unsubstituted perfluoroalkylated or hydrocarbon radicals; provided that R.sup.1, R.sup.2 or R.sup.3 is a perfluoroalkylated radical; and Y and Z are radicals which can bear a part derived from a sugar, a polyol, or a hydrophilic polymer such as polyethyleneglycol, a perfluoroalkylated part or a part derived from a pharmaceutically active molecule, and method for their preparation and use. These compounds can be included in preparations, emulsions, dispersions, gels, microemulsions, notably for biomedical uses.
