Have you noticed "PFAS" popping up in the news or on social media? You’re not alone; these “forever chemicals” have everyone talking. In a world already brimming with new acronyms (AHA, SPF, GRWM, anyone?), it’s easy to tune them out. But PFAS are worth a closer look, especially when it comes to skincare.
Let’s break down what they are, why they matter, and how we keep them out of Little Seed Farm products.
What Are PFAS?
We won’t go too deep into chemistry, but in the simplest terms, PFAS (short for per- and polyfluoroalkyl substances), often called “forever chemicals” are a large group of synthetic chemicals made up of very strong carbon-fluorine bonds, which is why they don’t break down easily in the environment—or in our bodies.
They’ve been in use since the 1950s, often added to products to make them smooth, water-resistant, or longer-lasting. You’ll find them in things like non-stick pans, some water-repellent clothing (like raincoats), certain synthetic activewear, waterproof mascara, and even stain-resistant fabrics. The catch? Once they show up, they tend to stick around… for a long time.
The good news? Companies are finally waking up to their risks and working to phase them out.
Why PFAS Matter
As research on PFAS continues to grow, we’re learning more about their lasting impact on both the environment and our bodies. With this knowledge, we can take steps to reduce exposure and make positive changes moving forward.
Because these chemicals barely break down, they can accumulate in soil, water, and living organisms over time. This buildup has been linked to concerns like potential hormone disruption, blood pressure changes, and organ function issues.
The research is ongoing but the International Agency for Research on Cancer (IARC) recently classified one type of PFAS (PFOA) as “carcinogenic to humans”, indicating strong evidence it can cause cancer in lab animals and limited evidence of testicular and kidney cancer in people. Although more research is needed, many experts agree that reducing PFAS exposure is a smart move whenever possible.
By phasing out PFAS from everyday items - clothing, cookware, and yes, personal care - we’re taking small but meaningful steps to protect not just our personal health but the environment as well. Cleaner water, cleaner air, and a healthier future: it’s a win-win for everyone.
How Do Products Typically Get Contaminated with PFAS?
PFAS can sneak into personal care products in two main ways:
1) On Purpose: Some brands include them intentionally to improve texture or water resistance (think “long-lasting” claims).
2) By Accident: Contamination might occur through ingredients sourced from polluted areas or improper manufacturing processes. So even if a brand isn’t trying to use PFAS, tiny amounts can still find their way in.
As a consumer, you’ve got power. Knowledge is everything here. Brands that test for PFAS (and share those results) help you avoid adding extra chemical baggage to your routine. More and more companies are steering clear of PFAS entirely, which means safer, cleaner options all around.
What About Regulation?
PFAS aren’t fully regulated on a national scale in many places, though some states, like Maine, have begun taking action against their use in agriculture and water systems. It’s a bit like the journey BPA took - initially, few knew about it, but as the science caught up, regulations and consumer awareness forced a change. We’re seeing a similar trend with PFAS: the more we learn, the more momentum there is to restrict or ban them. But until the rules catch up, it’s largely up to individual companies (and informed consumers like you!) to avoid them.
What Little Seed Farm Does
We’re serious about keeping PFAS out of our formulas, and we don’t just take our word for it, we put it to the test. Actually, three tests! We work with three independent labs to make sure our products stay PFAS-free, because thoroughness matters.
Here’s how we do it:
1) Test for Total Fluorine
As PFAS are fluorine-based, our labs start by looking for fluorine in our products. If there’s no fluorine, then there’s no PFAs, and we’re good to go. This is the case with the vast majority of our products. However, if fluorine is detected, we move to Step #2.
2) Check If It’s Organic or Inorganic Fluorine
If fluorine is detected, we dig deeper to see if it’s the kind we need to worry about (organic PFAS) or if it’s inorganic fluorine, which is considered safe in small amounts (think fluoride in toothpaste).
Our deodorants and other products keep coming back with a clean bill of health, which is exactly how we like it. Transparency is important to us, and we’re committed to making sure what you’re putting on your skin is as safe and clean as possible.
