The present invention relates to anionic detergent compositions, and in particular to shampoo compositions.
It is known that on storage anionic detergent compositions are subject to microbial spoilage, and in shampoos this can be particularly troublesome, and may result in precipitation, discoloration, gas formation and offensive odors. Antimicrobial agents have therefore been included in anionic detergent compositions, but difficulties are encountered in ensuring compatibility with the constituents of the composition.
It is an object of the present invention to provide an,- ionic detergent compositions especially for but not limited to shampoos in which the above disadvantages are avoided.
Accordingly the present invention provides an anionic detergent composition comprising an anionic, non-soap, non-sulphonate detergent and less than percent of a preservative and synergistic metal iodate unrelated to the liberation of iodine, together with at.
anionic detergents and the compounds are colorless and odorless.
2 The following non-limitative examples illustrate the invention.
EXAMPLE 1 The synergistic effect of detergent and iodate against spoilage organisms was shown by comparing the spoilage rates of solutions of mixed lauryl sulphates with and without added sodium iodate with those of distilled water and of sodium iodate solution. Materials Detergent: Ammonium lauryl-sulphate, 4 parts Monoethanolamine lauryl sulphate, 1 part Triethanolamine lauryl sulphate, 1 part Solutions were diluted to Cetavlon Value 245. Sodium Jodate: NaIO .H O. Solutions at 0.1% w/v concentration. Spoilage Organisms spoiled shampoo and detergent solutions; they consisted of Pseudomonas, Klebsiella, and, Citrobacter types, together with various unclassifiedQram-negative rods. Subcultures were grown in nutrient broth for 24 I hours at 37C. Single loop transfers were 'made to 9 ml. aliquots of nutrientbroth and further incubated for 24 hours. The broth cultures were pooled, and 0.25 ml. of this suspension was inoculated into each test solution.
Method Duplicate 25 ml. aliquots of sterilized test solutions were distributed in sterile MacCartney bottles, each bottle containing 30 glass balls. After inoculation with organisms, which were thoroughly dispersed with a Vortex JR mixer, themixtures were incubated at room temperature. Plate counts in nutrient agar were carried out at intervals over the following four weeks.
The resultsare shown in Table I.

' diethanolamine fatty acid amides (foam stabilizer) Microbiological findings indicated that the unpreserved formulation was highly susceptible to bacte rial spoilage. It was found that sodium iodate (0.1 percent) prevented the development of the native microbial flora initially in the unpreserved shampoo. However, it can be seen that the incorporation of 0.25 0.5 per cent iodate drastically-reduced the spoilage rate in experimentally infected shampoos and is superior to 0.05 percent formalin.
