Abstract
Herbal cosmetics are gaining popularity over chemicals for beauty products. However, natural products are often prone to deterioration. Therefore, stability and compatibility testing are the main examinations of the safety and reliability of herbal cosmetics. Liquid crystal structures provide better application performances than conventional emulsion systems in terms of stability, controlled release, and moisturizing. Rice is the most profitable crop in Thailand, and the skin healing benefits of rice have been reported. Thus, the current study aimed to develop a liquid crystal cream containing germinated brown rice extract (GBR) or biological cosmetic active ingredients, to study its efficacy on hydration effects and moisturizer, to identify the active ingredient content, such as gamma-aminobutyric acid (GABA), phenolic content, and to evaluate the physical properties and stability of the product. Results revealed that GBR contained GABA and a total phenolic content of 273.28 mg GABA/100 g of rice and 2.58 mg GAE/100 g of rice, respectively. The GBR-liquid crystal cream had good stability and moisturizing effect. The developed products were statistically significantly in hydrating more than a counter brand product. The product that increased moisture the most was the GBR-liquid crystal cream. The GBR-liquid crystal cream provided a high-efficiency moisturizing effect and reliability enabling it to be a premium commercial product shortly.
