| Summary: | The preparation and behavior of powder stearin-based methyl ester sulfonates (MES) with the addition
of builder as a glidant agent was studied. MES is an anionic surfactant and its performance is equivalent
to petroleum-based linear alkylbenzene sulfonates (LAS), the workhorses of the detergent industry. At
the same time, zeolites or soda ash were the alternative builders for non-phosphate-based detergent. The
behavior of powder MES properties was measured in terms of morphology, particle size, cohesion,
caking, and compaction. Before that, these palm stearin-based MES of carbon chain 16e18 with ratios of
98:2, 80:20, and 60:40 in flakes were ground using a high shear mixer by 23,000 rpm to produce powder
particles. Decreasing the particle size of MES powder can reduce the powder's cohesion, caking, and
compaction. The addition of zeolite or soda ash as a glidant in powdered MES can improve the caking
behavior. The high stearic in MES greatly influenced getting fine particle powders and required more
glidant agents. This powder MES with excellent powder characteristics can perform well as a bio-based
cleaning product. |
