Experimental Investigation to Determine the Concentration of Radon in Cosmetics Using a Nuclear Track Detector (CR-39)

Abstract

The nuclear track detector CR-39 is used in the detection of radon gas concentration in selected samples of cosmetics in the local market. Products of wide use are selected and employed in the current study. Six types of cosmetic products of different origins are tested by taking equivalent quantities of these products and putting them in plastic boxes. The detector is left with the samples for a period of 50 days. In addition to measuring the rate of surface evaporation of radon gas, measurements of the annual equivalent dose of radon gas are also carried out. The results show that the highest concentration of radon gas is in Charcoal Facial SCRuB (American origin) and it is equal to 0.0795 Bq/m3, whereas the lowest one in "bb" cream basis (5 in 1) is equal to 0.0355 Bq/m3. Based on specific international organizations and agencies, the concentration of radon in the samples under consideration is within the acceptable limits.

Test anti-aging activity in a face scrub preparation that contains coffee-grade active charcoal (Coffea arabica L.) with the addition of vitamin E

“…Conclusion: from the results of the study, it can be concluded that the face scrub preparation of activated charcoal coffee grounds (Coffea arabica L.) with a concentration of 3 % and vitamin E 5 % is a formula that meets the evaluation of the preparation and measures the effectiveness of anti-ageing Keywords: activated coffee charcoal (charcoal), face scrub formulation, anti-ageing, vitamin E and have better skin cleansing power than preparations without activated charcoal [7]. Activated charcoal as an adsorbent is very good if used in an exfoliant preparation such as scrubs and scrubs so that the skin regeneration process will also be better and can avoid the effects of premature ageing [8].…”
