COSMETICS PRODUCT Introduction to cosmetic products

By definition, cosmetics are substances intended to be used on the external surfaces of the human body, such as the skin, nails, lips, hair, teeth and mouth with the aim of sanitizing, perfuming and improving the external appearance of the body. Among the cosmetics, different groups can be identified: cleansers, deodorants and antiperspirants, perfumes, make-up, hair dyes, hair products, products for the treatment of the face and body, products for the beard, tanning and sun products and products for the ‘oral hygiene.

Given the daily contact to which the human body is subjected, the quality guarantee of cosmetic products is extremely important, both in terms of the absence of toxic and carcinogenic compounds for humans, and in terms of the presence in authorized concentrations of sensitizers of the skin that could cause allergic reactions and intolerance dermatitis. For this reason, the analysis of cosmetics concerns the entire product in its entirety, from the ingredients present, to the containers, wrappers and preservation packaging (packaging).


The analyzes are carried out on the basis of the type of cosmetic, its destination and method of application. Among the most common chemical assessments are heavy metals (such as nickel, chromium, lead, cadmium, arsenic and cobalt), hydroquinone, formaldehyde, phthalates and preservatives, such as parabens. Among the microbiological evaluations, we highlight the determination and counting of viable aerobic mesophilic bacteria, fungi and yeasts and the determination of Pseudomonas aeruginosa, Candida albicans, Escherichia coli and Staphylococcus aureus. The service also extends to the laboratory analysis of raw materials for the production of cosmetic products.

In addition to what has already been listed above, the Stante Chemical Laboratories, thanks to its microbiological sector, is also able to perform shelf-life tests of cosmetic products such as, among the most important, the Challenge test.

As a consultancy activity, we are able to provide assistance for the creation of the documents necessary for the marketing of cosmetics such as technical data sheets, safety data sheets and PIFs.
