Background: Each of natural plant-based oil have specific fatty acid composition that depending on their plant sources. So, they effect on hair physical properties. The saturated and monounsaturated fatty acids can penetrate into hair that they enhance the structure of hair for strength and flexible and polyunsaturated. The fatty acids can improve hair coat to make shiny, soft, and manageable.
Objectives: To study results of physical, chemical, stability, and preference of hair oil products and hair conditioner products from rice bran oil that replaced natural oil.
Methods: This research was an experiment in laboratory by created hair oil formula that contained rice bran oil and argan oil, also hair conditioner formula that contained rice bran oil and olive oil blends with sweet almond oil. Then, we compared physical and chemical properties including color, odor, product texture, pH, and viscosity. Besides, it tested a preference of the hair oil product at 20 people and the hair conditioner products at 27 people by using 9-point hedonic scale.
Results: There was no different of all parameters in physical, chemical characteristics, and paired preference tests between rice bran oil formula with argan oil and olive oil blends with sweet almond oil for hair oil products and for hair conditioner products, respectively. Stability test of rice bran oil formula for hair oil and hair conditioner products was adequately to use as the product ingredient.
Conclusions: The rice bran oil can be used for an emollient agent in hair oil and hair conditioner products by replacing natural plant-based oils formula in hair oil 100% and hair conditioner 75%. The results of this study yielded to reduce imported raw materials cost.
