Most Effective Ecocert-Compliant Fungicidal Preservative?

Posted by spadirect on January 27, 2019 at 10:21 pm

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!

@Belassi

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.

@Belassi and everyone else

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

Naticide (Parfum) from Singera
P-Anisic Acid from Dr. Straetmans

If you are specifically looking for a fungicide to supplement your other presevative

@MarkBroussard
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.

Sodium Dehydroacetate.

.It is inexpensive
. It is completely water soluble
. Usage rate is %0.1-0.6
. The mic for Aspergillus niger and Candida albicans is 200ppm or %0.02
