Preparation and Characterization of Coconut Oil Based Soap with Kaolin as Filler

Abstract

Soap is the product of saponification of fats with a base, which is used as a body cleanser, in the form of solid, foamy, with or addition of other ingredients and do not cause skin irritation. Clay (kaolin) is used as an active ingredient in cosmetics because of the high level of adsorption of substances such as oil, toxins, and others. The use of clay also been considered as a potential tanning agent in halal industrial applications. This study aimed to search for the effect of temperature reaction and addition of kaolin to the solid soap produced. The saponification reactions was carried out for 10 minutes in a reaction flask at a temperature that varied from 50ºC - 80ºC. The beginning stage was to heat the coconut oil to the reaction temperature and then mixed it with kaolin (10%, 12.5%, 15%, 17.5%, 20% wt.), followed by adding 35% NaOH. The reaction mixture was stirred at 250 rpm. The results of this study showed that all soap products met the Indonesia standard SNI.

Composition and physicochemical properties of Combretum collinum, Combretum micranthum, Combretum nigricans, and Combretum niorense seeds and seed oils from Burkina Faso

“…C. micranthum , C. collinum , C. nigricans , and C. niorense seed oils saponification values were similar to that of palm oil (190–209 mgKOH/g of oil), palm olein (189–199 mgKOH/g of oil) but lower than that of palm kernel oil (230–254 mgKOH/g of oil) and palm kernel olein oil (231–244 mgKOH/g of oil) (Codex Alimentarius, 2019). The higher the saponification number of oil, the higher the foaming capacity of its soap (Iriany et al, 2020). The four seed oils had saponification values similar to that of palm oil widely used in the soap industry (Boadu et al, 2017; Iriany et al, 2020).…”

“…The higher the saponification number of oil, the higher the foaming capacity of its soap (Iriany et al, 2020). The four seed oils had saponification values similar to that of palm oil widely used in the soap industry (Boadu et al, 2017; Iriany et al, 2020). Based on these results, all four seed oils examined could potentially be used in the soap industry.…”

Production of Solid Soap with Addition of Green Betal Leave (Piper Betle L.) Extract and Left Lemon Extract(Cymbopogon Nardus L. Rendle) As Antioxidants

“…Water content is the amount of water contained in the material expressed in percent. For example, the maximum water content in soap is 15% since the water content affects the hardness of solid soap [10]. In addition to affecting the hardness of soap with increased water content, it can accelerate the growth of microbes in the soap itself and affect the shelf life of soap that does not last long.…”

Halal Cosmetics: A Review on Halalan Toyyiban Concept in Soap Production

“…Specifically, soap is used as a body cleanser in solid or liquid, with or without additional substances that do not irritate the skin. Soap is commonly the product of the saponification process (Iriany et al, 2019). Scientifically, soap is a watersoluble anionic surfactant.…”
