The Effect of Hemp Seed Oil on Skin and Soap Performance

Abstract

The cannabis plant is essentially a variety of the Cannabis Sativa L. plant. It is used in the textile, energy, automotive and cosmetics. The use of oil derived from hemp seeds has become widespread in cosmetics. Hemp seed oil does not contain Δ9-tetrahydrocannabinol (Δ9-THC) and it is used in the production of food, biodiesel and polymers as well as cosmetics. In this study, different concentrations of hemp seed oil were used in cream and soap formulations, which are among the cosmetic products, and effect on skin hydration, sebum and transepidermal water loss (TEWL) on the skin was investigated. At the same time, the foaming test was applied to soaps containing different concentrations of hemp seed oil to see effects of soap foam performance. To analyse these, a rinse-off and leave-on product were selected. In soap formulations, there is positive effect on skin hydration and TEWL with sebum decrease. The most important change in cream formulations with respect to bar soap formulations is the increases in sebum. The effects of hemp seed oil on soap foam performance were examined. As a result of the study, its effect on the foam of the soap base which is used in this study is positive.
