Abstract:
1. Microparticles for stabilizing 3-iodo-2-propynyl butylcarbamate against discoloration, which comprise: a polymer that absorbs light over a range of ultraviolet wavelengths associated with 3-iodo-2-propynyl butylcarbamate discoloration by sunlight and other ultraviolet light sources; and a biocidal composition including 3-iodo-2-propynyl butylcarbamate and optionally, an additional biocidal material; which microparticles stabilize 3-iodo-2-propynyl butylcarbamate against discoloration by sunlight and other ultraviolet light sources, and have a particle size in the range of more than 20 to about 1000 microns and a surface area in the range of about 0.001 to about 0.9 m2 per gram.
