Bioscience · DNA authentication
Know what is really in your ingredients.
CSL scientists use real-time PCR and DNA sequencing at the Guires R&D Innovation Centre to screen for porcine DNA, confirm botanical identity and check GMO status, giving halal certifiers and brands proof, not just paperwork.
Guires Cosmetic Science Lab
Halal DNA Testing from Guires CSL
At Guires Cosmetic Science Lab, CSL scientists run halal DNA testing for cosmetics and ingredients at the Guires R&D Innovation Centre, using real-time PCR to screen for porcine DNA, plus botanical DNA authentication and GMO screening, so certifiers and brands have laboratory proof.

The work, in detail.
Porcine DNA screening for halal
Real-time PCR screening of raw materials and finished products for pig-derived DNA, supporting halal certification in Indonesia, Malaysia and the Gulf.
Botanical identity
DNA checks that a plant ingredient is the species stated, catching substitution and adulteration.
GMO screening
Screening of plant-derived ingredients for common genetic-modification markers.
Animal-origin checks
Screening for other animal-derived material in ingredients sold as plant-based or vegan.
Supplier verification
Testing incoming raw materials against the supplier’s certificate before approval.
Deliverables
What you receive.
How it runs
Step by step.
- SampleRaw material or product received
- ExtractDNA extracted and quality checked
- TestPCR or sequencing against target species
- ReportResults and interpretation
Results from the Guires R&D Innovation Centre support formulation decisions, ingredient selection and claims development. Where a market or retailer needs regulatory-grade data, such as GLP safety studies or accredited test reports, CSL arranges those studies as part of the project.
Questions
Asked before we start.
Does a negative result prove a product is halal?
It shows no porcine DNA was detected at the method’s sensitivity. Halal certification also depends on sourcing, processing and documentation, which CSL helps prepare.
Can DNA tests be run on finished creams?
Often, yes, but heavily processed ingredients may contain little intact DNA. For those, testing the raw materials is more reliable.
Which certifiers accept this data?
Certifiers set their own requirements. The data supports the certification file, and CSL can arrange testing at a laboratory a specific certifier recognises.
