SCDLP Broth with Polymyxin B – 250g | Selective Enrichment for Burkholderia cepacia
Selective Enrichment Medium for Cosmetic Contaminant Detection
SCDLP Broth with Polymyxin B provides optimal conditions for selective enrichment of Burkholderia cepacia in cosmetic products. The combination of lecithin, polysorbate 80, and polymyxin B creates a targeted environment for this specific pathogen while suppressing competing flora.
Key Applications:
– Burkholderia cepacia detection in cosmetics
– Personal care product quality control
– Cosmetic preservative efficacy testing
– Manufacturing environment monitoring
– Regulatory compliance testing
