The
constant development of the cosmetic industry has
generated the necessity to carry out microbiological
analysis on the raw materials used in the industrial
production of cosmetics as well as the final products,
with the purpose of obtaining products of good microbiological
quality. Cosmetic products are recognized to be substrates
for the survival and development of a large variety
of microorganisms, since they possess some of the
nutrients that facilitate growth such as: lipids,
polysaccharides, alcohol, proteins, amino acids, glucosides,
esteroids, peptides, and vitamins.
Also, the conditions
of readiness (oxygenation, pH, temperature, osmotic
degree, superficial activity, perfume, and essential
oils) present in the cosmetic products favor microbial
multiplication.Routine analyses to determine the microbiological
quality of a cosmetic product include the following:
Count of mesophilic aerobic microorganisms. Most probable
number (MPN) of total coliforms. Count of molds and
yeasts. Absence/presence of Staphylococcus aureus
probe. Absence/presence of Pseudomonas aeruginosa
probe.

Specific
analysis requirements raised by our clients in relation
to cosmetics are numerous and varied. These may include:
