test your product

Cosmetic products need to have specific tests made in order to confirm their safety.

In our lab we can perform several testing protocols according to GLP standards, among which are microbiology, stability, challenge, SPF and UVA testing, water resistance, compatibility, patch, efficacy and preliminary testings, safety in use, claim support, effectiveness prooving, clinical studies, packaging approval etc.

Microbiological tests

Microbiological tests shall be carried out on each batch of cosmetic product manufactured to determine whether any contamination has occurred during production and filling of the product. Microbiological testing checks the total number of bacteria, yeasts and molds. We also test the product for the presence of the most common pathogens in cosmetics such as: S. aureus P. aeruginosa C. albicans E. coli

Challenge testing

With Challenge test we test the effectiveness of the preservative to ensure that the product is resistant to all the challenges posed by the normal use of the cosmetic product. This test is performed in accordance with the internationally recognized standard ISO 11930.

Stability test

Stability testing of cosmetic products under controlled conditions is crucial to demonstrate the physical condition of the finished product does not change during transport, storage or on the shelf. The stability test must be carried out at the stage of cosmetic product development.

Compatibility test

Already when designing a cosmetic product, packaging plays an important role, as the type of packaging and packaging material can affect the final stability of the product. During testing, we must check that our formulation is compatible with the selected packaging so that there are no negative surprises after product is being placed on the market such as migration, peeling, etc.

Patch

A patch test is a method to determine if a cosmetic product causes an allergic reaction to the user's skin. This kind of test is always performed under dermatological supervision.

SPF and UVA

With performing UVA and UVB tests, we test the Product Protection Factor (SPF) and test the skin's response to ultraviolet (UV) radiation and protection from the product's rays. According to the legislation, UVA protection must represent 1/3 of UVB protection, which is why it is necessary to carry out both tests in order to state the protection factor with certainty.

water resistant

water resistant Proizvajalci vsakodnevno razvijajo izdelke z SPF zaščito, ki so med kopanjem vse bolj učinkoviti. Ti izdelki imajo na etiketi različne oznake, od znaka za “water resistant” do “waterproof”. Ta test nam pokaže ali je izdelek za zaščito pred soncem tudi obstojen po samem kopanju. Omogoča nam, da lahko navedemo dodatne trditve na naš kozmetični izdelek. Manufacturers develop SPF-protected products daily, which are increasingly effective while bathing. These products have different labels on the label, from the "water resistant" to "waterproof" sign. This test shows us whether the sunscreen product is also durable after bathing. It allows us to make additional claims on our cosmetic product.

Efficacy studies

Every user is interested in knowing how effective the product is. Claims on cosmetics, especially those supported by tests on the product itself, are certainly in big advantage when users are making their purchase decision. Such tests are also performed by out experienced team. You can choose from different performance tests such as: moisturizing effect, anti-aging effect, lifting effect, etc.
