480 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Society of Cosmetic Chemists Award Sponsored by the Miranol Chemical Company The Society of Cosmetic Chemists Award sponsored by the Mirand Chemical Co., Inc., was presented to Douglas Howes, Unilever Research Laboratory, for his outstanding achievements in the study of the precutaneous absorption of surfactants and the cor- relation of this absorption with skin irritation. An inscribed scroll and a $2,000 honorarium were presented formally by Dr. Karl Laden, Society of Cosmetic Chemists President, at the Awards Luncheon held May 5, at the Hotel Bonaventure in Montreal, Canada. , rtie Left to right: Dr. Karl Laden, SCC President Douglas Howes, Unilever Research Laboratory, Awardee
