The quality of a cosmetic product, as with other products, is defined by the manufacturer who initially chooses the characteristics that a product must offer.
On the other hand, the quality control of a product is intended to verify whether all of these defined characteristics meet the standard definitions and whether the product is maintained throughout its shelf life.
Quality control of cosmetics is important to ensure the effectiveness and safety of products and raw materials. Because of the rapid growth of cosmetics industries worldwide, efficient, cost-effective and fast methods are the priority for testing quality control of cosmetics. Some current techniques used by the cosmetic industry, rheology, sensory analysis can be applied to the efficient evaluation of cosmetics quality control.
Sensory analysis is a powerful tool. It applies experimental design and statistical analysis to learn about how people feel about a product when using or consuming a product, in other words it is used to indicate consumer acceptance of a particular product. Therefore, in the cosmetic analysis laboratory, the primary sensory analyzes are color, smell and appearance.
Physical analysis is also important for cosmetic products. In particular, it is possible to obtain information about its physical properties by analysis such as pH, viscosity, emulsion stability.
Heavy metal analysis:
Chemical analyzes specific to each cosmetic product can be performed. Especially in colored cosmetics such as lipstick and blush, heavy metal analyzes must be performed. Heavy metals have carcinogenic effects. It can also accumulate in the body and cause various metabolic diseases.
Does not include Tests and Claims Tests:
Recently, cosmetic products with less chemicals have become popular. By choosing such products by consumers, manufacturers write on the label that they do not contain these chemicals. For example, paraben-free, alcohol-free,
SLS –SLES-free statements are included in the labels.
According to the guidelines issued by the Ministry of Health, if such statements are included on the label, analyzes related to these do not contain tests should be performed.
Paraben-free, PEG-free, alcohol-free, SLS-SLES-free, silicone-free, phthalate-free to include the expression of these analyzes must be performed in the product.
In addition, assertion tests (such as permanent 24 hours, does not stain) must be supported by analysis reports.
Another test that should be performed in terms of the safety of the products in the cosmetic analysis laboratory is dermatological tests. Dermatological tests are especially important for baby products.
Cosmetic products must be microbiologically safe. Therefore, microbiological analysis must be performed in cosmetic products. Apart from a few low-risk cosmetics (hair dyes, etc.), microbiology is important for all cosmetic products. Especially baby products and products that come into contact with the eye area are more risky in this respect.
Microbiological analysis has an important place in cosmetic analysis laboratories. In microbiological analysis of cosmetic products, pathogen bacteria should not be found.
Another important test performed in the cosmetic analysis laboratory is the protective efficacy test. Challenge tests are used to measure the effectiveness of preservatives used in the product against microorganisms.
All these analyzes performed in the cosmetic analysis laboratory are also performed in our laboratory. You can send an e-mail to firstname.lastname@example.org for information about all these analyzes.
