LPT DILUTION BROTH 500 grams/bottle

LPT Dilution Broth is recommended by UNIPRO Publication for the homogenization of the samples in the analysis of cosmetic products. Tryptone provides nitrogen, vitamins, minerals and amino acids essential for growth. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Potassium phosphates act as a buffer system. Lecithin and Tween 80 neutralize quaternary ammonium compounds and inhibit the action of the preservatives. Antimicrobial preservatives are commonly used in cosmetic products in order to reduce their microbial contamination. The cosmetics, due to their nature, are sensitive to microbial contamination and should be preserved as they are used in eyes, damaged skin or in long period times.
