10 Natural Preservatives for Homemade Skin Care
In this article, you’ll learn about 10 natural and/or organic-approved preservatives to consider adding to your handmade products.
For years I made my family lotions and creams with no preservatives since I automatically lumped those into the “harmful chemicals” category.
What I didn’t realize is that there are quite a few nature-derived and organic compliant preservative options readily available to the home crafter!
But first, do you *really* need a preservative?
If you’re making something without water, such as salves, balms, lip balm, body butter, etc., you generally don’t need to add a preservative.
Once you add water, or a water-based ingredient (such as aloe, witch hazel, hydrosol), then you create a cozy place for bacteria and mold to grow.
I was a little dubious about this in the past – after all I couldn’t SEE bacteria or mold in my unpreserved lotions and creams and they looked and smelled fine. To get to the bottom of it all, I decided to perform some home microbial tests on my lotions and was pretty shocked at what I found hiding in them.
You can read about that in my article:
You may also find this video (from a link inside the Handmade Lotions & Creams eBook) interesting, if slightly gross (!), to watch.
In it, I test several of the lotion recipes found in the Handmade Lotions & Creams eBook Collection, and compare them to unpreserved lotion.
What if you’re ULTRA sensitive to preservatives?
I have a highly sensitive ‘canary in a coal mine’ kid, so I get it. I truly do.
If you can’t tolerate even these mild natural preservatives, make a single small batch of lotion/cream at a time, store it in your refrigerator, and use it up within a few days. I’ve also successfully frozen tiny batches of face cream, though haven’t tested longevity/success past one month in the freezer.

Where to Buy Preservatives
I’ve purchased from the first three shops, and have seen the others recommended for outside of the US:
- Formulator Sample Shop
- Lotion Crafter
- The Herbarie
- Voyageur Soap & Candle (Canada)
- Aromantic (UK)
- New Directions (Australia)
What’s the shelf life of lotion made with a natural preservative?
I get this question a lot and the truth is, it’s impossible to give an exact time frame.
It depends on many factors including the recipe/ingredients used, the environment it’s stored in, preservative combination, and type of container/jar it’s kept in.
In general, I expect a lotion made with my current favorite preservative (Geogard ECT) to give me at least a solid 5 to 6 month shelf life. I’ve kept some in good shape for up to 9 months, but usually use them up much sooner.
The Leucidal products are shorter lived and I’m happy with a 3 to 4 month lifespan from those.
If I make something for one of my several nurse family members/friends, and it’s critical that it stays germ free a long time, I use Liquid Germall Plus which isn’t natural at all so isn’t listed here, but is highly effective for that particular situation. You should get a 1+ year lifespan using that preservative.
The best way to find out is to make, test, experiment, and keep great records, then decide which combination works best for you and the recipes you like to use!
Tips to Extend Shelf Life of Handmade Lotion
- Use distilled water. Tap water can contain contaminants such as metals, minerals, or bacteria.
- Store your handmade products in a comfortable area with even humidity and temperatures. A bathroom, with its fluctuating temperatures and humidity is not a good place to store lotions and creams.
- Sanitize bottles, jars, equipment by spraying with 70% isopropyl alcohol and allowing to air dry.
- Use clean hands or gloves and tie hair back.
- Consider using airless or pump style bottles so your fingers won’t contaminate the lotion or cream. Don’t store water based products in metal tins.
- Aim to keep pH under 6, or in the ideal range for the preservative(s) you’re using.
