1 400D A new generation of natural diatomaceous earth for deodorants and antiperspirants High absorbency Body odour control Bare skin sensation

2 Diatomaceous earth is composed of microporous siliceous fossilized skeletal remains of aquatic algae, known as diatoms. Due to its microporous structure, diatomaceous earth offers high absorbency power for personal care products such as deodorants and antiperspirants. Using proprietary technology, Imerys has engineered the most water-and oil-absorbent diatomaceous earth product available on the market today, ImerCare 400D. Water-and oil-absorption of different minerals Oil absorption (ml/100g) Water absorption (ml/100g) Typical diatomaceous earth ImerCare 400D Perlite Kaolin Talc

3 ImerCare 400D controls body odour To assess the effectiveness of ImerCare 400D, the mineral s capacity to absorb volatile synthetic molecules was tested by an independent laboratory (Odournet). Different minerals were mixed individually with synthetic and then placed in an airtight Nalophan bag. Perspiration persistence and intensity were then evaluated at T=2H and T+26H by a panel of six experts, in compliance with EN Results 2g ImerCare 400D and 3.4ml synthetic left for 24H at 37 C Olfactometric analysis 400 Odour concentration (UoE/m 3 ) at T+26H The graph opposite quantifies the odour level of a product in terms of odour concentration which refers to the persistence of an odour and its resistance to dilution. The higher the odour concentration value, the more difficult it is to dissipate the smell. + talc + perlite + 400D Odour intensify (measured by 6 experts) at T+26H Intensity measurements This graph measures a product s odour intensity on a scale of 0-5 (0 = imperceptible, 5 = very high) compared to a reference scale of n-butanol. + talc + perlite + 400D Of the three minerals tested (talc, perlite and diatomaceous earth), ImerCare 400D demonstrated the highest capacity to absorb volatile odour molecules.

4 ImerCare 400D effectiveness validated by consumers The performance of a roll-on deodorant containing 2% ImerCare 400D was compared to a reference roll-on without any mineral content. The test was conducted with 33 panelists by an external laboratory (proderm). The two different roll-on test deodorants were applied by the panelists at home, once a day for a period of seven days. The panelists then filled out a questionnaire assessing the performance of the two products.

5 Results 100% of the panelists perceive a difference between the roll-on containing ImerCare 400D and the roll-on without any mineral content. Reponses to questions comparing the two roll-on formulations The roll-on containing 400D is absorbed more quickly than the reference* 18% 46% The roll-on containing 400D leaves my armpit feeling softer than the reference* 15% 42% The roll-on containing 400D leaves fewer stains on my clothes than the reference* 6% 33% 0% 10% 20% 30% 40% 50% Agree Disagree Responses to questions concerning roll-on formulation containing ImerCare 400D only No residues claim approved by 85% of panelists** 9% 85% Bare skin sensation claim approved by 73% of panelists** 6% 73% Reduced sweat flow claim approved by 58% of panelists** 24% 58% No unpleasant skin feelings (burning, itching) claim approved by 97% of panelists** 0% 97% *significant results (p-value<0.05) - test conducted by proderm on 33 panelists **significant results (p-value<0.001) - test conducted by proderm on 33 panelists The full panel study integrating no opinion responses is available upon request. 0% Agree 20% 40% 60% 80% 100% Disagree Based on the odour and user tests described above, the roll-on deodorant containing ImerCare 400D: Demonstrates high absorbency for body odour control Dries quickly, imparting a bare skin sensation Leaves skin feeling soft The recommended incorporation rate of ImerCare 400D in the formulation is 1 to 5%.
