Abstract
Symposium on 'Microbial Control', organized by the Pharmaceutical Society of Great Britain and the Society of Cosmetic Chemists of Great Britain. Synopsis--Some factors involved in the development of a TEST for PRESERVATIVE CAPA-CITY (challenge test) for SHAMPOOS are discussed. A microbiological survey of public WATER supplies revealed the presence of Gram-negative bacteria, including PSEUDOMONAS sp capable of utilizing ANIONIC DETERGENTS as a sole carbon and sulphur source by virtue of their inducible SULPHATASE ENZYMES. Tap water ttterefore provides a suitable source of challenge test bacteria which may be isolated on Ionagar containing 0.1 % detergent. The amount of slime produced by these organisms is increased during growth in detergent. Utilizing these data, a challenge test for shampoos is described.
