Performance and Characteristic Analysis of Liquid Glass Cleaner Product With Three Different Formulations

Abstract

Commercial liquid glass cleaners contain linear alkylbenzene sulfonate (LAS) surfactants derived from petroleum that are not renewable. The surfactant that can replace LAS is methyl ester sulfonate (MES) from palm oil, which is environmentally friendly. Ammonium hydroxide (NH4OH) can clean mold on glass. This research aims to determine the characteristics and performance of 3 different formulations of liquid glass cleaner and determine the best formulation and its comparison to commercial products. The manufacture of liquid glass cleaner products, namely water, was heated to 60 oC, then MES was added and left for 15 minutes. Then 1 mL of surfactant diethanolamide (DEA) was added and waited until homogeneous (±15 minutes). Then add 0.3 g of triclosan and wait until it dissolves (±15 minutes). The solution was then cooled, then 5 mL of bioethanol and NH4OH were added. Liquid glass cleaners are transparent, smells of ammonia, liquid, homogeneous, have no sediment, pH 10.5-10.8, viscosity 1.42-1.48 cP, specific gravity 0.995-0.997, surface tension 34.2-34.4 mN/m, moderate-strong microbial inhibition, and stable. The best product quality based on the characteristics and performance based on the hedonic test was the formulation of MES 3% and NH4OH 0.8%. The liquid glass cleaner has better quality on microbial inhibition. Commercial products have better quality in viscosity and surface tension. Both products have standard pH and specific gravity.
