Consumer testing panel : 20 subjects
Objective: Measure the sensory perceptions of O/W lotionsformulated with 5 wt. % varying humectant :
Zemea
Glycerin
Propylene Glycol (PG)
Butylene Glycol (BG)
Evaluations : Blind test with four-day conditioning and three-dayproduct use cycle. Formulations were randomized.
Results : Subjects completed a daily use questionnaire to reporttheir level of agreement on a scale of 1 to 7 with 10 differentstatements regarding each lotions sensory and use characteristics.

Summary of Results
All formulations produced statistically significant increases inhydration of the skin vs. the control for the 1 hour and 4 hour
assessments.
No statistical differences in skin hydration were observed
between the glycerin and the Zemea /glycerin mix at alltime-points.
Even at 24 hours, the Zemea blend and the glycerin
formulations were statistically the same in hydration.

In repeated consumer sensory studies, lotions formulatedwith Zemea are rated higher on all sensory attributes than
lotions formulated with glycerin.
Zemea provides good skin hydration results when used in a
formulation at both a 5% concentration as well as higherconcentration levels of 20%.
Zemea can successfully replace glycerin in skin care
applications, enhancing aestethics without compromizing
hydration performance of the formulation. Zemea blended with glycerin can improve the consumer
perceived aestethics in high moisturizing formula.
