Abstract

The growth of Indonesia's cosmetics industry reached 21.9%, with 913 companies in 2022 and 1,010 companies by mid-2023. Among the total products from local cosmetic companies, the largest market segment is personal care. Shampoo and bodywash are the two main categories of personal care cleansing products. Foam is an important indicator of product quality; however, technically, foam does not always correlate with the cleaning strength of a product. Nevertheless, consumers expect shampoos and body washes to lather easily and produce abundant foam. The foaming ability of a product is influenced by several factors, one of which is the addition of foam boosters. Cocamidopropyl betaine (CAPB) is the most used foam booster and is produced on a large scale. Another foam booster is lauryl hydroxysultaine (LHS) which has better foam-producing ability than CAPB. This study aims to determine the right formulation of LHS addition in shampoo and bodywash thus it meets the specified requirements. Shampoo and bodywash were prepared with several formulations, the samples were then tested for their viscosity, foam quality, and irritation potential. The results showed that LHS performed better than CAPB for the three parameters above. It was obtained that a dose of 2% LHS gave a better effect than 3% CAPB. It is, therefore, quite profitable from an economic and environmental perspective.

Abstract

Glycerol Monooleate (GMO) is synthesized via esterification, which involves the reaction between glycerol and oleic acid to yield monoglyceride esters. The esterification reaction is intrinsically slow, requiring the use of a catalyst to decrease the activation energy. The catalyst used in this study is a naturally occurring zeolite catalyst that has been altered through acid treatment and impregnation with Mg(NO3)2, and then subjected to calcination to convert it into MgO. Typically, this research consists of two steps: an initial phase where a natural zeolite catalyst is altered, followed by a subsequent phase where glycerol monooleate production. This study investigates the effects of different variables on the reaction. The variables include temperature (140–180oC), catalyst loading (3-10 %weight), glycerol to oleic acid ratio (2:1, 3:1, 4:1), reaction time (0–180 minutes), and stirring speed (125-525 rpm). The research results demonstrate that the highest conversion rate was achieved with a temperature of 180oC, a catalyst concentration of 10%, and a reactant ratio of 3:1 (glycerol to oleic acid). The ideal response time was found to be 120 minutes. The reaction kinetics can be estimated by employing a pseudo reaction equation that follows a first-order rate law. The rate constant, represented by k', can be approximated using the Arrhenius equation. The reaction has an activation energy of -18.64 kJ.mol-1, and the value of A is 1.41 cm3.g-1.minute-1.
