Most Effective Ecocert-Compliant Fungicidal Preservative?

In your experience, what have you observed to be the most effective (or among the most effective) Ecocert-compliant anti-mold fungicidal preservative for use in O/W emulsions skincare products?

I would greatly appreciate any suggestions, comments or discussion about Ecocert-compliant anti-mold fungicidal preservatives.

Thanks!

    you refere to Spectrastat™ G2-N? el Caprylhydroxamic Acid puede ser considerado como natural? Solo bajo la norma NSF/ANSI 305-2012?

  • Yes, G2-N. However the MOQ will probably be 55 gallons... enough to make 5,500 gallons of product.

    Could Spectrastat G2-N possibly/potentially provide sufficient broad spectrum anti-bacterial and anti-mold coverage to protect a product over an 18 month long shelf life?

    What preservative would you add to an O/W emulsion in addition to Spectrastat G2-N in order to give (or attempt to give) a skin product an 18 month long shelf life?

    I am aware that nothing is known until tested.  Knowing the most promising candidates to test is immensely helpful.

    Thanks again!

    I have had success with Geogard 221 (Benzyl Alcohol and Dehydroacetic Acid). Just make sure your pH is less than 6.
  • I can't comment on that because I don't use that variant of Spectrastat. The variant I have is caprylyl glycol and caprylhydroxamic acid and glycerine. Used at 0.7% I haven't ever seen a shelf life failure. I think I have samples going back two years on this preservative, and it's also been very tolerant of high levels of aloe vera and so forth. I can't stand the MOQ though, so I am shifting to KEM NAT.

  • Also be aware that caprylhydroxamic acid have some regulatory restrictions in China and others countries  if used as preservative or in special use cosmetics

    P-Anisic Acid (dermosoft® 688 eco by Dr. Straetmans) seems like an effective fungicide with optimal function up to 5.5 pH and effectiveness up to 6.5 pH in O/W emulsions.

    Does P-Anisic Acid have a pronounced scent?

    Have you noticed a marked drop off in fungicidal protection with P-Anisic Acid in emulsions above 5.5 pH?

    What is an example of a preservative system (Ecocert-approved or not) to which you have supplemented P-Anisic Acid as a way to fortify fungicidal protection? 

    Thanks for the suggestions!

    Again from the Dr. Straetman's line:

    Dermosoft 1388:  Sodium Levulinate, Sodium Anisate.

    or

    Phenethyl Alcohol, Pentylene Glycol, Propanediol (Linatural Ultra-3)

    p-Anisic Acid does not have a pronounced scent

    Don't forget Potassium Sorbate/Sodium benzoate. Cheap and effective.
