Formulation of Coenzyme Q10 Liquid Foundation With a Variations Linseed Oil as The Oil Phase

Abstract

Antioxidant Coenzyme Q10 (CoQ10) has properties as a sunscreen that can protect the skin from the aging process accelerated by UVB rays. Linseed oil (LO) formulated in cosmetics aims to find out the characteristics of moisturizer liquid foundation with LO as oil phase. In this study, cosmetic formulations were carried out using a modified method of emulsification evaporation. In the moisturizer liquid foundation CoQ10, three other formulas were used with LO concentrations of 3%, 5%, 7% to determine the effect of vegetable oils used on cosmetic characteristics. Evaluation of physical properties includes organoleptic, pH, viscosity, spreadability, and adhesivity. Evaluation of the acceptance of preparations was carried out to 15 panelists. The results of the study showed that the use of LO influences the characteristics of moisturizer liquid foundation CoQ10. The increase in LO concentration increases viscosity value, adhesivity, and decreased pH and spreadability, but the results obtained still meet the criteria. The results of the hedonic test showed no significant difference from the three formulas of 0.911 (P>0.05). It was proven that the panelists preferred formula one, which has a texture that is not too thick.

“…The adhesion test is related to the time needed for the preparation to contact with the surface of the skin and cause physiological effects as well as related to the comfort of the preparation at this time applied (Marviani & Rochman, 2021). Figure 6 depicts the results of the adhesion.…”
