Abstract
Disclosed are dry particulate compositions containing an anionic sulfonate or sulfate surfactant, fatty mono- or di-ethanolamide, alcohol, sugar and maltodextrin. The dry compositions readily disperse in water to form formulations which can form voluminous, stable, environmentally benign foams useful, for instance, in marking outdoor areas.
Claims10
A method for marking an area, comprising:
- (a) forming an aqueous dispersion comprising
- (a. 1) 20 to 60 wt. % based on components (a.1), (a.2), (a.3), and (a.4) of at least one anionic surfactant,
- (a.2) 1 to 10 wt. % based on components (a.1), (a.2), (a.3), and (a.4) of at least one component selected from the group consisting of fatty acid monoethanolamides and fatty acid diethanolamides,
- (a.3) 0.5 to 5 wt. % based on components (a.1), (a.2), (a.3), and (a.4) of at least one alcohol containing 8 to 18 carbon atoms, and
- (a.4) 20 to 55 wt. % based on components (a.1), (a.2), (a.3), and (a.4) of at least two sugars, one sugar of which is maltodextrin which comprises 10 to 30 wt. % based on components (a.1), (a.2), (a.3), and (a.4);
- (b) foaming the dispersion;
- and
- (c) applying the foam formed in step (b) to the area.
