During wartime in the 1940's there was shortages to deal with. Curtailed supply of alcohol meant more perfume but less cologne. Reduced supplies of fats and oils and unavailability of glycerinne meant substitutes were needed. Packaging was most difficult at this time and was important in the sales of products. Plastic was in short supply and metal containers and closures had to be replaced by something else. Cosmetics remained hugely morale boosting during this time.
