Product Description

Leucidal® SF Max Broad-Spectrum Anti-Microbial

A powerful all-natural broad-spectrum antimicrobial alternative to synthetic preservatives

For the serious lotion crafter, use in combination with gluconolactone to preserve your products like Burt's Bees natural skincare.

Available in two sizes, 4 oz. White mini-jug and 16 oz. white jug!

Burt's Bees was the front-runner in using a Lactobacillus Ferment, an all-natural alternative to synthetic preservatives. Burt's Bees uses a combination of Lactobacillus Ferment with Gluconate.

Now, you can protect your homemade skincare and cosmetic formulations with Leucidal® SF Max.

Add a 2-4% concentration of Leucidal® SF Max to your DIY skincare or cosmetic formulation. Blend until well mixed. Leucidal® SF Max may be hazy. To reduce haze, bring to room temperature before adding.

Consider adding a preservative like Gluconate to protect against yeast and mold. When finished, store in the fridge.

Part of the Leucidal line-up, a natural range of cosmetic products to protect your skincare. Leucidal produces novel antimicrobial peptides and broad spectrum antimicrobial results for formulators to use in their skincare recipes.
