Adlay seed and organic spent coffee grounds were extracted with the optimized condition.
The optimized condition which performed the highest antioxidant activities and total phenolic
contents of both extracts were soxhlet for 2 hours for adlay seed and partition with hot ethanol for
1 hours for spent coffee ground. In addtion, the spa cosmetic products were formulated, studied the
physical properties and stability test and evaluated the satisfaction by volunteers. Each of spa
product was performed with and without both extracts. Moreover, the nanoemulsion encapsulating
adlay seed extract and spent coffee ground extract were prepared and studied the physical
properties. Both nanoemulsion encapsulating extracts were used to formulate the new facial cream
and studied the physical properties. Moreover, the assessment for satisfaction of new facial cream
which contained nanoemulsion encapsulating extracts was studied and compared with the facial
cream which contained normal extracts. The results showed that the satisfaction of new facial cream
contained nanoemulsion encapsulating extracts was higher than the facial cream contained normal
extracts.
