The results showed that the lipase activity was stable when the volume fraction of olive oil was 25% and the temperature was at 40℃ with PH=7.5. Under the proper conditions, the effects of anionic and nonionic surfactants were investigated. The effect of nonionic surfactants on the activity of lipase was less than that of anionic surfactants. Finally, the analysis method was used to determine the activity of the lipase in the commercial detergent products. The results showed that the method can be used for the determination of lipase activity in both liquid detergent and laundry powder. However, the temperature and pH value of the detergent solution should be controlled strictly during the conduction of the determination.展开更多

In this study, we investigated the influence of numerous formulation and processing conditions on product discoloration. Product color was scrutinized using the L*a*b* color space, and in particular, L* and b*. Particle size, the method for introducing the optical brightener, and the raw material grade were very important in con trolling the optical properties of detergent granules. As the particle size decreased, the light reflected to the observer appeared brighter and bluer. This was observed as increased whiteness from L*= 84.03 with a particle size of >841 μm to L*= 90.59 with a particle size of <250 μm. Reducing the level of impurities found in the raw materials by changing the material source also improved color definition. A key finding is that the optical brightener should be applied by spraying and prepared by dispersion rather than dissolution. This improves the distribution within the granules and increases the whiteness when compared with pouring the brightener into the agglomeration vessel. Additional spray applications highlighted that brightener on the granule surface influenced whiteness more than embedded brightener. In addition, we report on the effects of the drying temperature and mixer impeller speed on powder color.展开更多
