So, you’ve sourced the silkiest butters, the juiciest extracts, and the freshest hydrosols. But if you’re skipping preservatives, you might be setting yourself up for a microbial mess.

In the world of cosmetic formulation, whether you’re a seasoned formulator or a passionate DIY skincare maker, preservatives are the quiet MVPs of your formulation, and with customers demanding clean, safe, and natural-based products, natural preservatives offer the best of both worlds: protection and peace of mind.

Let’s dig into the science behind them as well as spotlight a few powerful, plant-friendly preservatives you can get from Skin Foodie.

Why Even Natural Products Need Preservatives

If there’s water in your product (think lotions, toners, gels or even when you introduce the water with your hands like in a scrub), there’s a high chance for microbial growth, yep! that innocent-looking face cream could become a science experiment if not properly preserved.

Yes,  even “natural” can spoil,  and if you’re selling to others? The risk is higher, one contaminated batch could cost your brand’s reputation.

So, preservatives, especially naturally derived ones are a formulator’s safety net.

What Counts as a Natural Preservative?

Natural preservatives are derived from nature, think organic acids, plant-based alcohols, or naturally occurring salts. They’re typically:

• ECOCERT or COSMOS-compliant
• Gentle on skin
• Free from parabens, formaldehyde donors, or harsh synthetics

But here’s the twist: natural doesn’t mean weak. When used right, these preservatives are tough on microbes but kind to your customers’ skin.

Top Natural-Derived (and Clean-Approved) Preservatives You Should Know
