Quality Characteristics of Seaweed (Kappaphycus alvarezii) Transparent Solid Soap with Different Glycerine Concentrations

Abstract

Sabun merupakan salah satu bentuk sediaan kosmetik yang diminati oleh masyarakat untuk kulit. Penelitian ini bertujuan untuk mengetahui konsentrasi optimum dari gliserin dan mengetahui karakteristik sabun padat transparan rumput laut. Penelitian ini dilaksanakan pada bulan April-Oktober 2018. Pembuatan sabun menggunakan tiga perlakuan perbedaan konsentrasi gliserin (49 g, 59 g dan 69 g). Berdasarkan hasil penelitian, sabun transparan rumput laut memenuhi persyaratan sabun padat BSN 2016 kecuali nilai kadar air. Nilai kadar air sabun berturut-turut adalah sebagai berikut 29,70%., 29,87%., dan 39,77%. Pengujian kadar asam lemak bebas hasil terbaik yaitu pada konsentrasi gliserin 59 g sebesar 0,07%, hasil terbaik dari angka tak tersabunkan yaitu pada konsentrasi gliserin 49 g dan 69 g sebesar 0,16%. Hasil analisis sensori menunjukkan untuk parameter transparansi penambahan gliserin 59 g merupakan hasil terbaik, sedangkan untuk kesan bersih konsentrasi terbaik yaitu pada penambahan gliserin 49 g. Kata kunci: gliserin, Kappaphycus alvarezii, sabun padat transparan.

Physicochemical Quality of Transparent Solid Soap with The Addition of Forest Honey (Apis dorsata) as An Environmentally Friendly Sanitizer

“…Glycerine is made from the by-product of oil or fat hydrolysis. The level of free fatty acids has a directly proportional relationship to the water content of the soap, so the higher the level of free fatty acids, the more likely it is to trigger rancidity and reduce the shelf life of the soap [20]. High levels of free fatty acids can also cause the skin to feel rough and have low cleaning power [21].…”

Formulation of Solid Soap of Kaolin Clay Using Sucrose Ester

“…The water content in the soil soap ranged from 12% to 18.43%, as shown in Figure 7. Water content in the soap comes not only from the water added during the soap-making process but also from hygroscopic materials used in the transparent soap-making process, such as glycerin, sugar, citric acid, and NaCl [19]. According to Hambali et al [20], the higher the water content in the soap, the more it tends to shrink and lose consistency, resulting in quicker consumption during use.…”

“…Fatty acids are the main components of oils and fats, and the type of fatty acids used determines the characteristics of the resulting soap. The fatty acid content in the soap comes from vegetable oils and stearic acid used as raw materials [19]. The amount of fatty acids in the soap indicates both the total amount of saponified fatty acids and the free fatty acids present in the soap.…”

Physicochemic characteristics and antibacterial activity of solid soap with additional of collagen from tuna skin (Thunnus sp.)

“…In addition, the skin also needs protection from the dangers of various kinds of pathogenic bacteria, so protection is needed to avoid these pathogenic bacteria. One way to remove dirt mixed with sebum and avoid pathogenic bacteria is using soap [7].…”

“…Solid soap and liquid soap have their advantages and disadvantages, so there is no need to worry about their use. Solid soap consists of three types of soap, namely opaque, translucent and transparent [7]. Opaque soap is a type of soap that is commonly used, and compact in shape.…”
