1. INTRODUCTION PRACTICAL EVALUATION ON BARRIER CREAM- LIQUID As instructed by Dr. R Augustyn practical testing on Barrier Cream in Liquid form has been conducted on the premises of Inspectorate M&L (PTY) Ltd. 2. OBJECTIVE The objectives were to: i) Evaluate the protective properties. ii) Confirm the proposed packaging claim in respect of the product. 3. TEST SAMPLE A sample of Barrier Cream in Liquid form was submitted by Dr. Augustyn, this sample being employed throughout the test programme. 4. TEST PROCEDURE 4.1 Application and Removal 3 ml of liquid sample was applied to the hands uniformly and allowed to dry. Soilant was applied and allowed to dry, hands wiped with paper towel and washed with cold water and scrubbed with a sponge to aid removal. No other additional soap or other cleaning agents were employed in the removal process. 4.2 Soilants Used i) Bumper Dye ii) RSA Printing ink (oil + solvent based) iii) Spraypaint iv) Diesel Oil v) Shoe Polish vi) Glue vii) Tincture of Iodine viii) Epoxy Resin with Hardener ix) 10% Hydrochloric Acid x) Printing Ink (solvent based) xi) Potassium Permanagnate
4.3 Evaluation Efficiency was evaluated on the percentage removal by visual estimation once hands are wiped off with the paper towel and after being rinsed off with water and scrubbed with a sponge. The porcelain basins were also examined for staining after water rinsing. Our findings are reflected in Appendix I. 5. CONCLUSION Based on the pre-described test conditions, as performed by Inspectorate M&L we are of the opinion that: 1) The protective ability of the liquid sample is satisfactory. 2) The label claims are justified.
