Preservatives: NataPres (Ecocert)

NataPres is an Ecocert preservative I found at Lotioncrafter. I purchased it, but haven't used it, and that's primarily because of the need for a secondary preservative.

INCI: Glycerin (and) Leuconostoc/Radish Root Ferment Filtrate (and) Lonicera Japonica (Honeysuckle) Flower Extract (and) Lonicera Caprifolium (Honeysuckle) Extract (and) Populus Tremuloides Bark Extract (and) Gluconolactone.

NataPres is a water soluble preservative that should be added in the cool down phase at 50˚C or lower. It is good against gram positive and gram negative bacteria, but the company suggests you add a little something more if you want to boost its efficacy against fungi and yeast, so it's not considered a broad spectrum preservative. (Click here for information on what beasties might live in our products!) Its suggested usage is 0.5% to 3% in the cool down phase of your product. Keep the sealed container of preservative away from sunlight, and I'd suggest keeping the finished product in an opaque container just to be safe.

We know about the leuconostoc/radish root ferment filtrate because we've been talking about Leucidal for the past two days, and it's the main preservative in that product (click here and here). Honeysuckle extract is interesting because it contains natural parabens, but it may not be as effective a preservative as once thought (click here and scroll down a bit for those links). The gluconolactone is added to be a chelating and sequestering ingredient (like EDTA), a free radical scavenger, and a moisturizer that is on par with about 2% glycerin. (This isn't to say that the gluconolactone will behave this way in your product.)

The Populus Tremuloides Bark Extract comes from the quaking or trembling aspen, and it can be found on its own as Natricide (click for data sheet from Lotioncrafter). In this product, you'd find it at 54% to 60%, whereas in this product you'l find it at a maximum of 20%.

I find the ratios of ingredients in this preservative interesting. The glycerin is listed at 60% to 70%, the radish ferment filtrate at 20% to 25%, with the next three extracts listed at 1% to 20%, with the gluconolactone listed last 0.01% to 10%. If we do the math, if we have glycerin at the least at 60% and the radish ferment filtrate at 20%, we only have 20% left for the honeysuckle and aspen extracts. So what is the main preservative here? It appears to be the radish root filtrate, but this product doesn't promise to be as broad spectrum as the Leucidal products - and it's from the same manufacturer - so I'm feeling a bit confused. Is it the glycerin that makes it less effective? I really don't know.

A big down side of this preservative is the need to keep it in an opaque container away from the sun. It reminds me a bit of working with Tinosan. The other big down side is the need for another preservative that is better with fungi and yeast. You might consider using an organic acid like potassium sorbate or sodium benzoate as a secondary preservative, or something like Optiphen. But I don't think those things are Ecocert, so you might have a problem there.

Hey Susan! Interesting post, I'll wait you to try the preservative and tell us more ;)
I commented you for a question in an older post but because I'm not sure if you could see it, here's the link:

I purchased natapres roughly 3 weeks ago and tried it in a basic olive oil lotion right away at 1% today the lotion has a nice coat of mold over the top so I put it in the garage to let it grow more. I live in AZ and when I got the package it was probably close to 90degrees maybe more so that may have something to do with the growth.

Thanks for the recommendation on NataPres. It seems a help against bacteria but not against molds.

Not a good preservative on its own, but might work combined with cleaniness and other preservatives.

I tried a selfmade poplar extract at 5% and has indeed some preservative effect, though it still grows a bit of mold if you deliberatly spoil your cream with mold.

So, could be interesting combining it with other extracts (like honeysuckle, olive leaf) and essential oils.

Cynnamon and clove are very effective, even starting from 0.1%, lemongrass, palmarosa and tea tree are also good against molds, 0.5-1%.

Hi Anonymous. I appreciate your comments about your experiences, but there is no scientific evidence that any of the essential oils you have mentioned will work as anti-microbials. I wrote a post this the other day - if some essential oils are anti-microbial, why aren't we using them as preservatives - and you can see from it that it's not easy to use essential oils are preservatives.

solquartocrescente said...

Hey Susan, I actually used some essential oils combined and tested with a lab kit to detect bacteria and fungi.

They work. No bacteria or mold detected, even in challenge-tests.

I used a combination of several essential oils, their total combined ammount was less than 1%.

Another thing, Susan, if you go to pubmed you can find many scientific papers describing the antibacterial and antifungal activities of many essential oils, and at which concentration.
Therefore, it is incorrect when say there is no scientific evidence of their effects.

I understand why companies do not use these.

1) first, each combination of essential oils is specific to each recipe. Manufacturers prefer simplicity.

2) they introduce scent, then it is hard to work with fragrances.

3) it is much more expensive to use essential oils than synthetic preservatives.

4) they have allergens that have to be listed in their labels, even when the essential oils are used at levels safe.

Despite this, essential oils can be used as effective preservatives, as I have seen in my own experience.

In this post you mentioned Natricide which I googled and couldn't find hardly any information on. But I did find Naticide... and it is used as a preservative by some. Do you know anything about this product? Thoughts? Thanks!

Hi, I just bought NataPres from lotion crafter to use a facial lotion. Used it at 2% and in less than two weeks there was mold in the lotion. Bummer too because it wasn't cheap to make (darn you expensive acai berry oil). I used vitamin E with the oils and NataPres during the cool down phase. Any recommendations on what I can use with it to make sure my products don't grow any molds/fungi?? Something without parabens please.

Susan Barclay-Nichols said...

Hi Anna. Have you looked at the preservatives section of the blog? Parabens are only one type of preservative we can use!

MSC said...

Hi Susan,

You mention trying NataPres in combination with Sodium Benzoate. Any pointers on how much of each to use? I have some NataPres I've never tried and I'm considering ordering some Sodium Benzoate to use with it.

How about amticide coconut? Lotion crafter states it is effective against fungi and mold and often used with Leucidal. it is also ecocert

I have used NataPres in my lotions while experimenting PRIOR to selling on Etsy, and so far so good. Lotioncrafter says it can be added POST the emulsification process and to the final product. This is when I chose to mix it in. It has worked for me. -Angela
