Well, we've truly gone and done it now, we've changed our preservative.
After years of looking for a natural preservative that was of a broad enough spectrum to drastically inhibit the growth of molds, yeasts, fungals, etc., we have finally found something to replace the old Germall Plus. this sound innocent enough until you read the INCI name: Propylene Glycol (and) Diazolidinyl Urea (and) Iodopropynyl Butylcarbamate. Though there was less than 2% per formulation, none the less, it was still there. We have felt it a necessary evil so to speak, as there was nothing else on the market that would function as efficient or with as little of a presence in the formulation as this did.
That is until we discovered the new and highly acclaimed ALL-NATURAL broad spectrum preservative, trade name Leucidal Liquid PT, INCI name: Lactobacillis Ferment.
We cannot say it as well as the manufacturer has:
Leucidal Liquid PT is a probiotic-based ingredient created by the fermentation of Lactobacillus in a defined growth medium and at specific conditions. Lactobacillus is one of the species of microorganisms used to produce fermented products such as sauerkraut and kimchi, a Korean dietary staple from cabbage. During the fermentation process, in the presence of both standard growth media components and undecylenic acid derived from castor beans, the pH and oxygen levels for Lactobacillus are pushed to their limits to induce the production of secondary metabolites as a response to stress. These synergistically active compounds are capable of providing conditioning benefits. An additional growth characteristic of the lactic acid bacteria family is the production of novel antimicrobial peptides. In their natural environment, these antimicrobial peptides provide a competitive advantage to the lactic acid bacteria against other potentially competitive organisms.
After fermentation, lysozyme is added to the culture to facilitate a controlled cell lysis. This step helps ensure the release of the antimicrobial peptides for maximized activity.
The ability of Leucidal Liquid PT to act as a broad-spectrum antimicrobial is enhanced by the presence of water-soluble undecylenates generated by the Lactobacillus during the fermentation process. Undecylenic acid is an oil-soluble, unsaturated fatty acid typically produced by thermal conversion of ricinoleic acid derived from castor oil. Castor oil is a 100% vegetable, biodegradable, natural and renewable resource. In nature, trace quantities of undecylenic acid are also found in human tears and hair.
Biotransformation of undecylenic acid by Lactobacillus allows for the generation of water-soluble undecylenates. This process permits the inclusion of this well known anti-fungal agent without the need for undesirable synthetic solvents. In addition to its antimicrobial properties, this odd-carbon number unsaturated fatty acid is a very effective skin moisturizer.
There you have it ... We have gone all-natural in our preservative ...
