LIQUID SOAP PREPARATION FORMULATION USING A COMBINATION SUNFLOWER SEED OIL and Virgin Coconut Oil (VCO)

Abstract

Sunflower seed oil and virgin coconut oil (VCO) have important benefits for the skin, making them attractive ingredients in liquid soap formulations. Sunflower seed oil contains vitamin E and essential fatty acids that maintain skin moisture and health, while VCO has antimicrobial, antioxidant, and skin softening properties. The combination of these two oils is expected to produce a liquid soap with superior quality in terms of softness, moisture, and skin cleansing. This study aims to find the optimal formulation by testing the physical properties and stability of various liquid soaps containing the combination for maximum benefits for the skin. VCO oil using a combination of sunflower seed oil is formulated in the form of a liquid soap preparation with variations in the addition of sunflower seed oil F0 base, F1 5 ml, F2 10 ml, F3 15 ml and K +. The liquid soap preparation was tested for physical properties such as organoleptic tests, pH tests, homogeneity tests, viscosity tests, foam height tests and physical stability tests. Organoleptic tests showed that F0 was clear, F1 was clear cloudy, F2 was cloudy, F3 was pale yellow, and K + was light brown, all in the form of homogeneous liquids with a distinctive aroma. The pH test showed that F0 had a pH of 8.5; F1 and F2 pH 8.3; F3 pH 8.2; and K+ pH 9.3. All formulations were homogeneous. The viscosity test was consecutive: F0 664.1 mPa.s, F1 556.6 mPa.s, F2 426.1 mPa.s, F3 981.5 mPa.s, K+ 475.6 mPa.s. The foam height was consecutive: F0 56 mm, F1 59 mm, F2 59 mm, F3 56 mm, K+ 59 mm. The physical stability of all formulations did not show significant changes in organoleptic, pH, foam height, homogeneity, and viscosity. The making of liquid soap with a combination of sunflower seed oil and VCO showed changes in physical properties such as viscosity, pH, and foam power, but these changes were not significant. This combination remains stable and effective for liquid soap formulations
