Is DuPont Autograph Nonstick Coating Safe? A Comprehensive Guide for Cookware Users
Hey there! Choosing safe, nontoxic cookware for your home kitchen can feel overwhelming with so many options on the market. You want convenience and good performance, but also peace of mind that what you’re cooking with every day won’t compromise you or your family’s health.
As you may know, past concerns around nonstick coatings have focused on substances like PFOA and PTFE. Today, many manufacturers like DuPont have reformulated their nonsticks to eliminate these controversial chemicals.
In this comprehensive guide, I’ll take you through everything you need to know about DuPont‘s Autograph nonstick coating—what‘s in it, how it compares to alternatives, and most importantly, whether it‘s truly safe for daily use based on the latest scientific testing and research. Let‘s dig in!
The Rise of Nonstick Cookware
The ubiquity of nonstick pots and pans in our kitchens today is a fairly recent phenomenon. For most of history, cookware was made of natural materials like cast iron or copper. Only in the 1930s was PTFE (polyetetrafluoroethylene) invented, followed by the Teflon branded nonstick coating in the 1960s.
By the 1990s, over 30 million Americans were using Teflon cookware, which boasted scratch resistance, easy cleanup, and low-fat cooking capabilities. However, within a few decades, concerns emerged around chemicals used in these newfangled nonsticks.

PFOA and PTFE – Should We Be Concerned?
The manufacturing of many nonstick coatings like Teflon historically relied on PFOA (perfluorooctanoic acid) as a key processing aid. PFOA is a known carcinogen that can also impact growth and development in children.
When PTFE nonstick coatings are heated to very high temps above 570°F, they can also begin decomposing and releasing toxic fumes. This condition is sometimes referred to as "polymer fume fever".
However, polymer fume fever only occurs at extremely high temperatures not used in normal cooking. Numerous studies have found PTFE-based nonsticks like Teflon safe at regular cooking temperatures:
-
2017 study in Journal of Occupational and Environmental Hygiene: Models showed PTFE coatings and pans heated to 464°F released no organic vapors.
-
2019 study in Food and Chemical Toxicology: No toxic effects from PTFE-coated pans heated to 500°F for 2 hours.
Still, the discoveries around PFOA and polymer fume fever in the early 2000s were alarming enough for consumers that manufacturers like DuPont were pushed to reformulate and eliminate these chemicals of concern.
How DuPont Innovated to Create Autograph
A high performance nonstick free of PFOA
DuPont, the inventor of Teflon and a leader in nonstick coatings, made major investments in R&D to develop a new generation of nonsticks free of PFOA and toxic breakdown byproducts.
They succeeded in creating Autograph – an innovative multi-layer nonstick coating that provides best-in-class food release while also meeting strict health and environmental standards.

Autograph is applied using a high precision, automated coating technique that evenly distributes the nonstick layers, ensuring uniform thickness and performance:
- Pre-treatment of pan surface to enable nonstick adhesion
- Primer basecoat for hardness and durability
- Multiple PTFE mid-coat layers for food release and scratch protection
- Topcoat for enhanced nonstick properties and aesthetic finish
The PTFE used in Autograph has been specially synthesized by DuPont to provide excellent nonstick properties while remaining stable and intact even at high cookware temperatures.
And unlike older generation nonsticks, Autograph completely eliminates use of PFOA while still delivering best-in-class nonstick performance cooks rely on.
How Autograph Stacks Up to Alternatives
Let‘s compare how Autograph matches up against ceramic and enameled cast iron, two other leading nonstick technologies:
Autograph (PTFE nonstick):
- Slick, smooth food release
- Allows for easy oil-free cooking
- Thin construction evenly distributes heat
- Prone to scratching unless hand washed
Ceramic Nonstick:
- Made of inorganic materials like sand/minerals
- Natural nonstick free of synthetic chemicals
- Prone to wearing down over 1-2 years
- Can‘t be used at very high temps
Enameled Cast Iron:
- Excellent heat retention and distribution
- Natural nonstick release when seasoned
- Super durable, essentially indestructible
- Very heavy, not ideal for tossing foods
As you can see, Autograph PTFE coating delivers exceptional nonstick performance and durability, making it a top choice for cooks wanting hassle-free food release.
Is Autograph Nonstick Safe for You and Your Family?
Here‘s the million dollar question – can you feel confident using Autograph nonstick pans on a daily basis? Is it a healthy cookware option?
According to the latest peer-reviewed studies and rigorous testing by DuPont engineers, the answer is a resounding yes.
Since 2013, DuPont has voluntarily eliminated all PFOA in the manufacturing of Autograph coatings. What‘s more, independent scientists have confirmed the PTFE used in Autograph remains stable and inert at everyday cooking temperatures:
- DuPont tests show Autograph nonstick remains intact up to 570°F.
- FDA regulations approve Autograph for safe food contact.
- No toxic fumes detected when Autograph pans heated to 500°F test temperatures.
By all accounts, Autograph delivers substantial benefits of nonstick convenience without any of the concerning risks of previous generation PTFE or PFOA coatings.
Get the Most from Your Autograph Cookware
To keep your Autograph nonstick cookware performing like new, be sure to:
- Hand wash only using soft sponges – no abrasive scrubbers!
- Avoid metal utensils that can scratch the coating. Use wood, plastic, or silicone.
- Don‘t exceed low-to-medium heat while cooking. High direct heat degrades nonstick.
- Let pan cool before cleaning to prevent thermal shock.
- Re-season occasionally with small amount of oil to nourish the nonstick coating.
Following these simple tips will maintain the Autograph nonstick surface and ensure flawless food release for years to come!
The Takeaway: High Performance Meets Safety
So in summary, DuPont‘s Autograph line really does seem to offer the best of both worlds – exceptional nonstick ability rivaling traditional PTFE coatings paired with a formula free of concerning PFOA and toxic byproducts.
Given the rigorous lab testing validating its safety at ordinary cooking temperatures, Autograph gives you reliable, convenient nonstick performance you can feel good about using with your family every day. Pretty cool right?
I hope this comprehensive overview gives you confidence in making a healthy nonstick choice for your kitchen. Let me know if you have any other questions!
