880 JOURNAL OF THE SOCIETV OF COSMETIC CHEMISTS The foregoing is an attempt to correlate certain polymeric properties with one desirable characteristic of a hair spray formulation, namely curl retention. Obviously, such considerations as ease of combing, adhesion to the hair, gloss, and feel are all important to ultimate con- sumer acceptance which in the final analysis spells the success or failure of a commercial product.

REEl)* Presented December 6, log7, New York City Synopsis-The time-consuming, repetitive nature o[ the product development-evaluation cycle is described. A conscious, planned approach to the psychosensory evaluation of prod- ucts by the scientist is urged prior to any practical evaluations by nonscientific evaluators. The benefits in terms of anticipating consumer reactions, saving time, and developing novel products having a high degree of sensory appeal are indicated. INTRODUCTION During the past decade business interest in the exercise known as industrial research and development has exploded. It has exploded because there is now a full recognition of R & D and the importance of its role in keeping businesses alive and providing an internal mecha- nism for company growth. In the minds of company managers, R & D translates into products and profit: the products vital to the defense and expansion of a com- mercial business the products vital to the achievement of corporate and business development goals the products vital to financial success which is the hallmark of the successful business executive. The answer to profit or perish! With all this recognition of R & D in the business world have come many questions. Implicit in many of these questions is a desire to improve the R & D process, make it more efficient, and get products to the marketplace more rapidly. The purpose of this paper goes in this direction. * Gillette Research Institute, 1413 Research Blvd., Rockville, Md. 20850. 881
