Consumer Sensory Testing2009 Protocol

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.

Protocol: Consumer Sensory Testing


Objective: Measure the sensory perceptions of 3 different

formulations with a varying humectant component:

Zemea (20 wt.%)

Glycerin (20 wt.%)

Zemea/Glycerin Mixture (10 wt.% each)

Applications : On days 1, 2 and 3, each lotion was applied to the

volar side of the forearms.

Evaluations : On day 3, reporting of the level of agreement on ascale of 1 to 7 with 10 different statements.

Study conducted by Princeton Consumer Research, Princeton, NJ, in March 2015.

Objective: Measure the skin hydration levels of 3 different

formulations with a varying humectant component:

Zemea (20 wt.%)

Glycerin (20 wt.%)Zemea/glycerin Mixture (10 wt.% each)

Evaluations : Using a Corneometer CM825 (Courage and Khazaka,

Germany), moisturization readings of the lower leg area were

taken at 1 hour, 4 hour and 24 hours.

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.
