Molecular Solutions for Cosmetics
QACS uses DNA technology to provide fast & cost effective cosmetic testing services to the personal care industry. Our molecular services on Microbiome analysis, Microbiological surveillance and Authenticity testing for cosmetics assist you reach product safety, ensure absence of pathogens and substantiate cosmetic product claims.
QACS with 18 years of clinical efficacy testing experience and technical know-how of molecular biology tools offers Microbiome testing in the form of clinical trials to substantiate product microbiome claims. Our dedicated team of scientists (dermatologists, microbiologists and molecular biologists) offers a variety options on clinical evaluation of skin microbiome to address your product needs and budget in the form of customized protocols.
We use classical microbiology and DNA identification via Sanger Sequencing of the isolates or Next Generation Sequencing according to the depth that you need to analyze your product in order to support claims. At DNA Microlab, member of QACS, microbiome testing projects consist of the following stages:
- Trial design
- Suitable volunteers selection
- Microbiological, Molecular, Physicochemical skin measurements during trial
- Microbiome samples analysis
- Results interpretation
- Dossier to substantiate claims
QACS scientific solutions resolve causes of microbial contamination through accurate microorganism identification to benefit Quality Assurance & Quality Control processes. We investigate the microbiological origin and perform analysis of the deeper causes upon request. DNA Microlab, member of QACS, provides species level identification and information information on the ecology, classification, growth conditions and possible pathogenesis.
DNA identification techniques present a reliability advantage over other methods e.g. APIs that are metabolic. MALTI TOF or other immunochemical methods.
Worldwide pathogenic bacteria are a growing public health concern. We perform fast (24h) and accurate pathogen detection via Real Time PCR to ensure product safety.
Pathogenic bacteria of the genus Salmonella, Listeria, Shigella and others after enrichment are detected in 24h via Real Time PCR.
Increasing legislative demands and regulatory bodies challenge microbial-free production procedures. Sometimes, the use of antibacterial, bacteriostatic or bactericidal preservatives is not enough to ensure consumer safety. Consequently, absence of microbial contamination from production areas and subsequently from finished products is necessary. To do so, a constant monitoring system should be established, and corrective actions should be taken for continuous improvement. At QACS our specialized personnel undertakes Environmental monitoring by swabs, air monitoring, microbiological analysis of raw material or water with our specialized personnel.
Microbes isolated from finished products, ingredients, water samples and production areas, are candidates for identification especially if, their numbers exceed alert or action limits. The name of the species of the microorganism could play a significant role in the investigation of its source and in the root cause analysis. We offer scientific guidance and solutions to further facilitate the microorganism’s investigation and proceed to root cause analysis of any microbial contamination.
Botanical Authenticity, Halal, Vegan
For HALAL and VEGAN claims, labs analyze products with a sensitive and reliable molecular method, Real Time PCR. Detection limits must be below 0,1% for the presence of pork or meat DNA to be labeled.
Genetic identity e.g. Barcoding is a powerful tool in favor of botanical authenticity. By analyzing and “reading” a piece of DNA containing the plant genetic identity, an indisputable “DNA certificate” of the species of the organism is obtained. In this way, the product or raw material acquires a seal of authenticity and the producer or distributor is protected from counterfeiting (replacement of part or all of it by another product of lower value) and the product acquires a greater added value.
