INCI name: 

Lactobacillus Ferment


  • Active Concepts

Leucidal® SF Max is Derived from Lactobacillus acidophilus, a probiotic bacterium traditionally used to ferment milk into yogurt. Created by the fermentation of Lactobacillus in a defined growth medium, this specific manufacturing process yields a unique peptide with broad spectrum, antimicrobial and conditioning properties.

It is important to note that this material is not a preservative – but multifunctional active with antimicrobial properties. As such it cannot be used as 1:1 replacements of more traditional preservative systems. Natural antimicrobials can be used to compliment and balance more traditional preservatives.

SF: Salicylate Free

Demonstrated potential to promote a balanced skin microbiome when compared to more traditional antimicrobials.

Biocidal Activity: Strong against bacteria, partial against yeasts and moulds

MAX: Optimised for better antimicrobial performance than Leucidal® SF

Best Combined with AMTicide® Coconut for boosted preservative effect.
