Challenge test

Challenge test: Efficacy of preservative system is to be used in the overall evaluation of the antimicrobial protection of a cosmetic product. The antimicrobial protection of a product can come from many sources: chemical preservation inherent characteristics of the formulation package design manufacturing process The evaluation of the preservation of a cosmetic formulation is based…

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…

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 &…

Mucosal Tolerability

Mucosal Tolerability: Mucosal tolerability test is useful to assess the tissue-specific irritation potential of the test product and is evaluated through different ex vivo (engineered tissues) models: Oral epithelium Gengival epithelium Vaginal epithelium Airway epithelium Intestinal epithelium ServicesAuditingCertificationConsultingInspectionTests and AnalysisChemical AnalysisEfficacy TestsMicrobiological TestsSafety TestsTraining Markets Cosmetics Medical Devices Nutrition Household Products Get more info about…

Genotoxicity and Mutagenicity

Genotoxicity and Mutagenicity: The evaluation of genotoxicity and mutagenicity represents an important step in the safety assessment of products and is used for their classification and labelling.

Patch and Controlled Tests

Patch and Controlled Tests: Human patch and controlled testing is a branch of our safety assessment program aimed at evaluating the effects of products coming into contact with the skin: Irritation (skin inflammation resulting in skin redness and swelling) Photo-irritation (skin inflammation resulting in skin redness and swelling after UV exposure) Sensitization (elicitation of an…
