Compositions having low quantities of volatile organic compounds (VOCs) and uses thereof are generally disclosed. In some embodiments, the compositions are aqueous compositions, such as aqueous suspensions, suitable for use as coating or paint compositions. In some embodiments, the compositions are aqueous compositions that include, among other components, a film-forming polymer and a coalescing aid. In some embodiments, the coalescing aids are derived from a renewable feedstock. Methods and systems for making such compositions are also disclosed. Novel coalescing aids are also disclosed.

1. A coating or paint composition comprising: an aqueous carrier;a film-forming polymer; anda coalescing aid, which comprises one or more compounds of formula (I): wherein: R1 is C5-16 alkenyl or C4-16 oxyalkenyl, each of which is optionally substituted one or more times by substituents selected from the group consisting of a halogen atom, —OH, —O(C1-6 alkyl), —SH, —S(C1-6 alkyl), —NH2, —NH(C1-6 alkyl), and N(C1-6alkyl)2; andR2 is C1-6 alkyl or C1-6 oxyalkyl, each of which is substituted one or more times by —OH. 2. The composition of claim 1, wherein R1 is C5-16 alkenyl or C4-16 oxyalkenyl, each of which is optionally substituted one or more times by —OH. 3. The composition of claim 1, wherein the moiety defined by R1 has exactly two non-conjugated carbon-carbon double bonds. 4. The composition of claim 1, wherein R1 is —(CH2)7—CH═CH—CH2—CH3, —(CH2)7—CH═CH—CH2—CH═CH2, —(CH2)7—CH═CH—CH2—CH═CH—CH3, —(CH2)7—CH═CH—CH2—CH═CH—CH2—CH3, —(CH2)7—CH═CH—CH2—CH═CH—CH2—CH2—CH3, or a mixture thereof. 5. The composition of claim 4, wherein R1 is —(CH2)7—CH═CH—CH2—CH3. 6. The composition of claim 4, wherein R1 is —(CH2)7—CH═CH—CH2—CH═CH2. 7. The composition of claim 1, wherein R2 is —(CH2)2—OH, —CH2—CH(OH)—CH3, or —(CH2)3—OH. 8. The composition of claim 1, wherein the film-forming polymer is a natural latex, a synthetic latex, or a mixture thereof. 9. The composition of claim 8, where the film-forming polymer is a synthetic latex. 10. The composition of claim 9, where the synthetic latex is an acrylic polymer, polyvinyl acetate, polyvinyl chloride, styrene-butadiene rubber, acrylonitrile-butadiene rubber, or a mixture thereof. 11. The composition of claim 1, wherein the weight-to-weight ratio of film-forming polymer to coalescing aid ranges from 5:1 to 200:1. 12. The composition of claim 1, wherein the weight-to-weight ratio of water to coalescing aid ranges from 4:1 to 100:1. 13. The composition of claim 1, further comprising a pigment. 14. The composition of claim 1, further comprising a thickener, a rheology modifier, a surfactant, a defoamer, a co-solvent, or any mixtures thereof. 15. The composition of claim 1, further comprising a biocide. 16. The composition of claim 1, wherein the composition is an emulsion. 17. The composition of claim 1, wherein the composition has no more than 0.5 kg/L of volatile organic compounds (VOCs), as measured by Method 24 of the United States Environmental Protection Agency. 18. The composition of claim 1, wherein the composition is a paint composition. 19. The composition of claim 1, wherein the composition is a coating composition. 20. A method of painting or coating a surface, comprising: providing a surface to be coated or painted; andapplying to the surface a composition of claim 1.
