To the Editor:—
I am at present engaged in a revision of my book "Cosmetic Materials: Their Origin, Characteristics, Uses and Dermatological Action," the foreword to which is being contributed by a Harley Street dermatologist. In the interests of the industry, the user, and the medical profession, I am anxious to obtain as much information as possible concerning primary irritation or sensitization arising from the use of substances employed in the cosmetic, toilet, and pharmaceutical industries, and for this purpose I would like to receive brief details from any of your readers of any instances in which the offending ingredients have been definitely confirmed by skin tests. Such information will be personally acknowledged, and full credit will be given to the source in the new edition.
