OPTIMASI ASAM STEARAT DAN TEA PADA FORMULA SEDIAAN KRIM EKSTRAK KULIT PISANG KEPOK (Musa paradisiaca L.)

Abstract: Banana kepok peel has flavonoid compounds used as antioxidants. The aim of this research is to get optimum formula of cream by combination of stearic acid and trietanolamin on good physical propertie of cream. Cream was made with stearic acid 15% minimum concentration and maximum concentration 17%, triethanolamine with minimum concentration 2% and maximum concentration 4%. The optimization of the formula was using the simplex lattice design method with parameters are pH, viscosity, spreadability, adhesion and … Show more

“…The type of oil-in-water (o/w) cream used emulsifiers such as triethanolamine, sodium stearate, potassium stearate or ammonium while the water-in-oil (w/o) type used an emulsifier in the form of polyvalent soap, span, and cera. The use of triethanolamine as an anionic emulgator will form a very stable o/w emulsion when combined with the appropriate free fatty acids such as stearic acid because it does not undergo discoloration such as oleic acid (Saryanti et al, 2019). Cream with combination of the use of triethanolamine and stearic acid as emulsifiers were stable during the storage period (Cahyati et al, 2015).…”

“…Pada penelitian ini hanya formulasi 5 dan 6 yang memiliki pH yang sesuai dengan rentang pH normal kulit yaitu 4,5-6,5 [16]. Selain itu, pH sediaan juga dapat mempengaruhi kestabilan asam stearat dan TEA sebagai emulgator [17]. Formula F4, F5 dan F6 menunjukan kadar TEA sebesar 1%, 1%, dan 1,2%, dimana kadar TEA tersebut merupakan kadar TEA yang lebih rendah dibandingkan formula yang lain.…”

“…Menurut Saryanti et al (2019) uji pH dilakukan untuk mengetahui krim yang dihasilkan bersifat asam dan basa dilihat dari nilai diperoleh. pH yang terlalu asam atau basa akan menimbulkan iritasi pada kulit sehingga perlu kesesuaian sediaan krim dengan pH kulit.…”
