A concentration range of 0.25-3% of AEROSOL OT-B, based on the weight of the powder, is recommended. The "AEROSOL" OT-B may be incorporated by simple blending and mixing. The presence of highly alkaline powders such as soda ash in the dry mixture will not hydrolyze or decompose the AEROSOL OT-B. On addition to water, the OT-B gives immediate wetting action before hydrolysis can occur.
