Abstract
Abstract The aqueous emulsions based on (a) 100 parts by weight of organopolysiloxanes which contain polar groups on Si--C-bonded hydrocarbon radicals and (b) not more than 50 parts by weight of alkyl polyglycosides which are stable toward high concentrations of foreign electrolytes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
40 words
An aqueous emulsion comprising (a) 100 parts by weight of an organopolysiloxane which contains polar groups on Si--C-bonded hydrocarbon radicals and (b) at least 5 parts by weight but not more than 50 parts by weight of an alkyl polyglycoside.
Claim 2
Dependent Claim
40 words
An aqueous emulsion comprising (a) 100 parts by weight of an organopolysiloxane which contains polar groups on Si--C-bonded hydrocarbon radicals and (b) at least 5 parts by weight but not more than 50 parts by weight of an alkyl polyglycoside.
Claim 3
Dependent Claim
109 words
An emulsion as claimed in claim 1, wherein the organopolysiloxane (a) has the general formula R.sub.n R'.sub.m SiO.sub.(4-n-m)/2 (I) in which R represents identical or different, optionally substituted hydrocarbon radicals or hydrocarbonoxy radicals having 1 to 18 carbon atoms, hydrogen atoms or hydroxyl radicals, R' represents identical or different Si--C-bonded substituted hydrocarbon radicals containing polar groups, n represents an integer having the value 0, 1, 2 or 3, m represents an integer having the value 0, 1, 2 or 3 with the proviso that the sum n+m has an average value of 1.8 to 2.2, and m is chosen such that the polyorganosiloxane contains at least one radical R'.
Claim 4
Dependent Claim
33 words
An emulsion as claimed in claim 1, wherein the polar groups bonded to Si--C-bonded hydrocarbon radicals are amino, ammonium, epoxide, hydroxyl, amido, mercapto, carboxyl and/or sulfonic acid groups and esters or salts thereof.
Claim 5
Dependent Claim
12 words
An emulsion as claimed in claim 1, which additionally comprises a cosurfactant.
