Alkaline cleaning compositions for non-horizontal surfaces

摘要

The present invention relates to cleaning compositions suitable for cleaning and disinfecting non-horizontal surfaces. The invention comprises an ether carboxylate or ether sulphate in combination with an amphoteric surfactant and with a non-ionic surfactant at a certain ratio which can be applied preferably in the form of foam at room temperature, preferably for the use in industrial and institutional cleaning products.;A cleaning composition comprises:
(a) One or more compounds of formula (I)
R1—O—(CH2—CH(R2)—O)n(CH2CH2O)m—X−(A)1/zz+  (I);wherein X− is a CH2COO− group or a SO3− group, preferably a CH2COO− group, R1 is linear or branched, saturated or unsaturated alkyl or alkenyl chain having from 4 to 30 carbon atoms, R2 is a C1-C3 linear or branched alkyl chain, A is a suitable countercation, n and m are 0 or an integer number between 1 to 30, wherein the sum of m+n is at from 0 to 30, preferably from 1 to 15, and z is 1, 2, or 3;
(b) one or more amphoteric surfactants(c) a non-ionic surfactant(d) water up to 100 wt % with respect to the total weight of the composition;wherein the molar ratio between the sum of the components (a) and (b) and component (c), that is ((a)+(b))/(c), is from 3 to 16.5, preferably from 3.7 to 15.9.
