Cosmetic products

Water-containing products including many cosmetic products can be subject to a proliferation of microorganisms. Without sufficient preservation this can lead to deterioration in which cosmetic products may show a change in odour, discolouration, mould growth, gas formation, separation of emulsions or change in viscosity making the product unacceptable to the consumer. Such deterioration invariably creates substantial financial damage and loss of image for the cosmetic manufacturers. In addition, microbiological contamination presents a real danger, leading to a health risk that microorganisms are potentially pathogenic. Cosmetic manufacturers are themselves responsible for the safety of the products they manufacture and commercialize. They are legally obliged to insure their products so that they do not pose a health risk to consumers. 

Products with an action against microorganisms are used in some cosmetic products, not only as preservatives but also as special products : in anti-dandruff preparations to combat microorganisms that cause the formation of dandruffs ; in anti-perspirants to inhibit the growth of microorganisms responsible for unpleasant body odour; in dental and oral hygiene products to combat the formation of dental plaque ; as antibacterial agents in skin cleansing products to treat young skin problems  ; in antibacterial hand washing products.  

Contamination limits have been clearly defined for the following products cosmetics, they are classified according to categories. Category 1 includes the products most likely to cause an infection in the consumer because of the fragility of the body area (eye contour and mucous membranes) in contact with the formula. The qualitative and quantitative limits are for the total mesophilic aerobic flora of 100 CFU/g or ml. Category 2 includes all other products and the limits are 1000 CFU/g or ml.  

The rRegulation (EC) N°1223/2009 of 30 November 2009 relating to cosmetic products sets out in Annex V thereof the list of preservatives permitted in cosmetic products.
