Stability test

Stability test: The purpose of stability testing (also according to ICH Guide Lines) of products is to ensure that a new or modified product meets the intended physical, chemical and microbiological quality standards as well as functionality and aesthetics when stored in certain set conditions. These studies can be also used to determine the “Period…

Chemical Quality control analysis

Chemical Quality control analysis: A wide range of technical competences and expertise, combined with high standard equipments (HPLC, GC-MS, AA etc.), allows analytical testing of active ingredients and/or impurities either by official or taylor made protocols. Preservatives content Sunscreens (Cosmetic) active ingredients titration Regulated ingredients verification Impurities detection and levels/quantification Heavy metals traces Process water…

Reproductive toxicity

Reproductive toxicity: A set of in vitro testing for the reproduction risk assessment is performed, basing on assisted reproduction techniques, such as the in vitro oocyte maturation and fecundation assays on bovine model. In vitro maturation test: an assay reproducing the process of oocyte maturation, which corresponds to the pre-ovulatory in vivo phase that allows…

Ecotoxicity

Ecotoxicity: These assays are aimed at evaluating the environment risk hazard of substances, involving a number of different terrestrial and aquatic bioindicators (toxicity to algae Pseudokirchneriella subcapitata – OECD 201, crustacean Daphnia magna – OECD 202, fish Brachidanio rerio – OECD 203) and Biodegradability testing (OECD 301 and 306) ServicesAuditingCertificationConsultingInspectionTests and AnalysisChemical AnalysisEfficacy TestsMicrobiological TestsSafety…

Acute Toxicity

Acute Toxicity: Acute systemic toxicity testing concerns the assessment of the systemic toxic effects of a single dose or multiple doses of a product by a particular route (oral, dermal, inhalation). BALB 3T3 NRU cytotoxicity in vitro assay is useful to estimate starting doses for acute oral systemic toxicity tests. Officially accepted in vivo tests…

Sensitization

Sensitization¬†efficacy is assessed using different techniques: Sensitization tests are useful to assess whether the product in exam may cause adverse effects involving immunological mechanisms; in vitro methods are currently under validation process. The human Cell Line Activation Test (h-CLAT) quantifies the induction of protein markers on the surface of THP-1 cell lines after exposure to…

Skin Irritation and Corrosion

Skin Irritation and Corrosion: Topical exposure to chemicals can lead to adverse skin effects. Depending on the severity and reversibility of the response it is possible to distinguish between skin corrosion and irritation. Corrosive substances irreversibly damage the skin, while irritant substances lead to a reversible local inflammatory reaction. In vitro test methods, including assays…

Ocular Irritation

Ocular Irritation A number of OECD Test Guidelines based on in vitro methods related to the endpoint “Eye Irritation” is currently available or proximate to validation/update. A stepwise testing strategy is recommended for the assessment of the eye irritation/corrosion potential of cosmetic/household substances. Our testing services include: Organotypic in vitro assays:¬† Bovine Corneal Opacity &…
