Abstract
Compositions including ether-capped poly(oxyalkylated) alcohol wetting agents. The wetting agents are low-foaming and have good biodegradability, and can be used in a variety of applications, for example in polymer, anti-foaming, biocidal, coating, fertilizer, pharmaceutical, and drilling fluid compositions.
Claims28
A wetting composition comprising:
- (a) from about 0.01% to about 50% by weight of the composition of a wetting agent, wherein said wetting agent comprises an ether-capped poly(oxyalkylated) alcohol having the formula:
- RO(R1O)xCH(CH3)OR2
- wherein R is selected from the group consisting of linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms;
- R1 may be the same or different, and is independently selected from the group consisting of branched or linear C2 to C7 alkylene in any given molecule;
- x is a number from 1 to about 30;
- and R2 is selected from the group consisting of:
- (i) a 4 to 8 membered substituted, or unsubstituted heterocyclic ring containing from 1 to 3 hetero atoms;
- (ii) substituted or unsubstituted, unsaturated cyclic or aromatic hydrocarbon radicals having from about 4 to about 30 carbon atoms;
- (iii) a 7 to 13 membered substituted, or unsubstituted polycyclic ring;
- and
- (iv) a hydrocarbon of the formula:
- —(CH2)y—X
- wherein y is an integer from 0 to 7, and X is a 4 to 8 membered substituted or substituted, cyclic or aromatic hydrocarbon radical;
- and
- (b) from about 0.1% to about 99% by weight of the composition of an adjunct ingredient.
