Are EcoCert Preservatives Really Safe?
As someone who’s passionate about using natural, safe ingredients in everything I create at Little Prairie Herbal Apothecary, I’ve spent a lot of time researching different preservatives that meet EcoCert standards. EcoCert is a certification that focuses on natural and organic ingredients, which sounds reassuring. But as I’ve learned, not all “natural” preservatives are as safe as they seem.
Let’s talk about some of the more common preservatives you might see on products labeled "natural" or "organic." Some of these are marketed as EcoCert-compliant, but they come with their own risks—and here’s why I’m cautious.
Common EcoCert Preservatives and Their Hidden Risks
Many EcoCert-approved preservatives are widely used in natural skincare products, yet some of them raise concerns when it comes to long-term safety. Here are a few that might surprise you:
Sodium Benzoate: This one might sound familiar. It’s commonly used in foods and cosmetics because it’s derived from benzoic acid, a naturally occurring compound. However, when sodium benzoate comes into contact with vitamin C (ascorbic acid), it can form benzene, a known carcinogen. Even in small amounts, this chemical reaction is something I want to avoid in any product I offer.
Potassium Sorbate: Another preservative often found in EcoCert-approved products, potassium sorbate is used to prevent mold and yeast growth. But some studies suggest that over time, it can cause skin irritation, especially for those with sensitive skin. While it’s considered safe in low concentrations, the potential for irritation and sensitivity still concerns me.
Phenoxyethanol: This preservative is found in many "natural" skincare products, but it's controversial. It’s often touted as a safer alternative to parabens, but phenoxyethanol has been linked to allergic reactions and skin irritation. In some cases, it can even affect the nervous system. For something so commonly labeled as “safe,” it has enough red flags that I steer clear of it.
Even with EcoCert’s good intentions, the science behind some of these preservatives isn’t as solid as I’d like, and I believe there’s always a better option when it comes to our health.
Why We Use Oil-Based Products
Because of these safety concerns, I’ve chosen to focus on small-batch, oil-based products for now. One of the biggest benefits of oil-based formulations is that they don’t require the same types of preservatives that water-based products do. Without water, bacteria and mold don’t have the same environment to grow, which reduces the need for synthetic or risky preservatives. Most oil-based skincare products can last up to 30 months on the shelf and 12 months after opening.
Oils like coconut oil, olive oil, sunflowee oil, and others have their own natural protective properties. They not only nourish the skin but also help extend the shelf life of a product in a safe and natural way. By sticking with these types of products, I can ensure that I’m offering you something that’s both effective and as safe as possible.
Experimenting with Natural Fermented Preservatives
While oil-based products are my go-to for now, I’m also exploring natural ways to preserve water-based products, and this is where fermentation comes in. Some new, innovative preservatives are derived from fermented ingredients, offering a more natural alternative to synthetic options. Two that I’ve been experimenting with are Amticide Coconut and Leucidal SF Max.
Amticide Coconut is a natural preservative derived from the fermentation of coconut fruit. It has been shown to have antimicrobial properties that help fight off mold and yeast, making it a promising option for natural skincare products. Because it’s coconut-based, it aligns with my commitment to using ingredients that are as close to nature as possible. What I love about Amticide Coconut is that it can be effective without the harsh effects of synthetic preservatives.
Leucidal SF Max is another exciting natural preservative. It’s created through the fermentation of Lactobacillus, a type of bacteria that’s used in probiotics. This preservative helps protect against bacteria and other microorganisms. Because it’s derived from fermentation, Leucidal SF Max provides a more natural way to preserve products while still offering the protection necessary to ensure safety and stability.
While these fermented preservatives show promise, I’m still in the process of experimenting with them to find the best formulations for my products. The goal is to one day create stable, water-based products without relying on synthetic chemicals. I’m hopeful that through continued research and testing, we’ll find a combination that works beautifully while staying true to the natural ethos of Little Prairie Herbal Apothecary.
Looking Ahead
In the meantime, I’ll continue to focus on oil-based products that don’t require harmful preservatives. But know that I’m always searching for ways to make my products even better. Whether it’s through experimenting with natural fermentation processes or keeping a close eye on new research, I’m committed to offering the safest, most effective products for you and your family.
There’s so much more to learn about natural preservation, and I believe that one day we’ll find an even better way to protect our formulations without compromising on safety. For now, I’m grateful for the oils, herbs, and other natural ingredients that allow me to craft high-quality, preservative-free products that align with my values—and yours too!
