Challenge test – Preservative efficacy testing
Check the efficacy of your preservatives system in order to be certain that your products are resistant to the growth and development of potentially harmful microorganisms.
The experienced scientists of QACS Laboratory will suggest the most efficient type of a challenge test: in accordance with EP, USP, ISO 11930, with mixed cultures, recontamination test, or wet wipes protocol.
Stability of a cosmetic product
Within these tests, the protocols of which are adapted to your product and demands, we offer:
Stability studies;
Packaging compatibility;
Storage under certain conditions;
Determination of PAO (period after opening);
Functionality, sensory features, as well as chemical and microbiological characteristics.
It is important for every manufacturer to prove that their product retains physical, chemical, and microbiological characteristics, as well as functionality and aesthetic quality under the prescribed storage conditions and throughout its shelf life.
Stability tests are necessary during product development, reformulation, change of technology and place of production, and change of packaging material.
Determination of impurities and allergens
Determining the presence of impurities and traces of impurities ensures the legal compliance of products and the safety of users.
QACS Laboratory is GMP certified for the analyses of:
Heavy metals;
Impurities such as phthalates, formaldehyde, etc.;
Nitrosamines;
Allergens;
Solvent residues.
Clinical efficacy tests
QACS Laboratory offers a wide range of clinical tests, state-of-the-art equipment, a wide base of volunteers, and standard and personalized protocols.
Within efficacy tests, we offer:
- Ophthalmological testing;
- Tests for proving hydration, wrinkle and redness reduction, skin elasticity, whitening, sebum control;
- Testing anti-dandruff efficacy;

In Vitro efficacy tests
In accordance with the regulatory requirements regarding the ban on animal testing and the development of alternative methods, QACS Laboratory offers alternative methods of testing sensitization, toxicity, efficacy, and tolerance to the cosmetic product, validated by both ECVAM and in-house.
These tests include:
In vitro test for eye irritation, corrosion of the eye and skin;
In vitro test for inhalation toxicity in accordance with good laboratory practice.
Dermatological testing
Implies the assessment of potential irritations and allergic reactions to a cosmetic product.
In order to prove the claims that a product is non-irritating to the skin, a Patch test is used on a number of volunteers, involving a forty-eight-hour occlusion followed by a clinical assessment of the skin condition by a dermatologist.
The claim of a “hypoallergenic product” can be proven by the HRIPT test, which implies repeated applications during a long time period in order to monitor the compatibility of the product with the skin and its allergenic potential.
