Good to know: "100% Natural Latex" assures a product made solely from harvested rubber tree sap without synthetic materials. Using generally safe chemicals like sulfur and zinc oxide, the vulcanization process doesn't synthetically alter the latex but stabilizes its inherent qualities.

Latex Processing

Different attributes can be enhanced depending on the manufacturing process.

Dunlop Latex Process: This method, used for about a century, involves pouring natural rubber sap into a mold, adding minimal ingredients like Zinc, Sulfur, and soaps to form a gel-like substance. It's then baked, washed to remove impurities, and baked again for drying. The result is a dense, durable foam. Dunlop latex often meets the Global Organic Latex Standard (GOLS), requiring at least 95% organic content. Its straightforward production process, using minimal additives, aligns well with these standards.

Talalay Latex Process: Developed in the 1940s for a less dense foam, the Talalay process starts similarly with pouring rubber sap into a mold. The mold is only partially filled, and synthetic materials like styrene-butadiene rubber and other chemicals are sometimes added. The mixture is then vacuum-sealed and flash-frozen with carbon dioxide before baking. This process results in evenly distributed air pockets within the foam. However, most Talalay latex does not meet GOLS standards, and the exact chemical additives are often undisclosed, leading to potential concerns about human health. One exception is Vita Talalay, which achieves OEKO-TEX certification.

For Talalay latex products, especially mattresses, be aware that chemicals may be introduced post-processing. Its lower density can require adhesives to bind smaller pieces together, forming larger sheets. This practice can introduce additional chemicals into the final product.

Overall, while both Dunlop and Talalay processes start with natural rubber latex, their production methods and the additives used vary significantly. Dunlop latex generally offers a more health-conscious choice, meeting higher organic standards. In contrast, Talalay latex, with its potential use of synthetic additives and post-processing chemicals, requires more careful consideration.

Tier 4: Avoidable Materials

Petroleum-based Synthetics

In the world of fashion, textiles, and everyday essentials, a variety of materials have become staples due to their adaptability and cheaper cost of production. Yet, many of these, derived from petrochemicals – essentially refined oil – present health risks that can no longer be overlooked.

The concerns are wide-ranging, but the evidence is mounting.

As these synthetic materials break down, they shed small pieces of plastic, which have become known as microplastics.

Particularly concerning is the ability of microplastics to cross the blood-brain barrier. This barrier is a critical defense mechanism of the body, protecting the brain from toxins. However, new studies have shown that microplastics can bypass this barrier, potentially leading to neurological issues that are not yet fully understood.

Other studies have shown that exposure to plastics and plasticizers can disrupt the endocrine system, affecting hormonal balance and fertility functions. Microplastics can lead to changes in gut microbiota and cause inflammation, potentially impacting digestive health. Microplastics have also been observed in human lung tissues, suggesting a risk to respiratory health. Most concerning? All of this research is relatively new.

Wearing these fabrics and materials on our bodies and using them throughout our home environment is, unfortunately, only one part of the problem…

When discarded, they contribute to the burgeoning waste in landfills and oceans, where they persist for centuries, posing a threat to ecosystems and contaminating the food and water sources we depend on.

Our stance is clear: The most effective way to mitigate the hidden dangers of these plastics is to avoid them entirely.

To simply stop purchasing fabrics and materials containing toxic synthetics (plastics).

To embark on a plastic-free lifestyle.

That said, the more familiar you are with today’s commonly used hazardous materials and fabrics, which we’ll cover below, the better consumer you can be. Are we trying to save the world? No. Are we virtue signaling? No. Greenwashing? Not that, either.

Our goal is to promote healthier choices simply.

Because it all starts with you – looking after your health.

By taking care of our health and wellbeing, you can also contribute to protecting our planet from further pollution.

Polyester

A synthetic fabric made from petroleum-based fibers, known for its durability, wrinkle resistance, and quick-drying properties. Polyester alone makes up a staggering 50% of the fabrics used in America today – a number that’s still rising – primarily due to its low cost and versatility.

While it is less toxic compared to some other plastics, its manufacturing process involves petrochemicals and can release harmful emissions. Polyethylene items can leach chemicals, particularly when heated or in contact with oily substances, potentially contaminating food or drinks. When polyethylene products break down, they release microplastics that can contaminate water and soil, ultimately entering the food chain and potentially impacting human health. The widespread use of polyethylene, especially in disposable products, highlights the need for more sustainable alternatives and better waste management practices to mitigate its environmental footprint.

Acrylic

Acrylic is a synthetic polymer derived from fossil fuels that can be formulated to mimic the properties of natural fibers like wool. The acrylic fabric is known for its lightweight, soft, and warm characteristics.

Uses: Commonly found in clothing (sweaters, fleece jackets, gloves, hats, socks), home textiles (blankets, rugs, carpets), upholstery, and even craft supplies (yarn, felt). Acrylic is also well-suited for awnings, boat covers, and outdoor furniture due to its resistance to fading, mildew, and sunlight.

Good to Know: Acrylic is one of the most dangerous, commonly used fabrics in the world today. Studies show acrylic sheds significantly more microplastics than other fabrics during washing, polluting the air you breathe, water, and our food chain. In the study, researchers found acrylic released over 700,000 microplastics per wash, compared to polyester's 496,000 and cotton-polyester blends 138,000.

While extremely harmful toxins/chemicals aren’t commonly present in the final product, the production process of acrylic does warrant some consideration. It involves toxic base substances like Polyacrylonitrile and Acrylonitrile. Polyacrylonitrile is highly flammable and mimics cyanide poisoning when inhaled, while Acrylonitrile is a toxic liquid, harmful to the eyes, skin, lungs, and nervous system and is directly linked to certain cancers.

A range of other chemicals (formaldehyde, phthalates, chlorine, and solvents such as acetone and dimethyl formamide) and flame retardants (bromine compounds) are used to produce some forms of acrylic that we won’t even get into.

While the risk from wearing acrylic clothing may be lower, especially if washed before wearing, the presence of these toxic substances in the fabric's lifecycle makes acrylic a less desirable choice for health-conscious consumers.
