For many, spring means stocking up on detergents, surface and upholstery cleaners, and laundry boosters to tackle the grime that built up over winter. The problem is, many conventional products rely on a long list of harsh, harmful chemicals that can affect your health, your family's wellbeing, and the environment.
The good news? Thanks to advances in safer ingredient technology, consumers no longer have to choose between clean and safe. Today, we're spotlighting 9 chemicals to avoid when looking at the ingredient list on your products, and what smarter alternatives look like.
1. Fragrances
Over the years, consumers have been conditioned to believe that smells like lemon, lavender, or "fresh scent" indicate a clean, odor-free space. The truth? Most fragrances mask the problem instead of eliminating odor, and they can have a negative impact on human health in the process.
Fragrance is having a moment in the health and wellness conversation, and for good reason. The word "fragrance" on a label can represent a cocktail of hundreds of undisclosed synthetic chemicals, many of which have been linked to allergies, asthma symptoms, skin irritation, and potential hormone disruption. If your goal is to reduce synthetic chemical exposure, either seek products that use essential oils for fragrance or look specifically for “fragrance-free” claims (don’t reach for “unscented” – these products contain additional chemicals used to mask the odor of other ingredients).
When looking for products to manage odor, seek out ingredients that neutralize odors at the source rather than masking smells. Itaconix® ONZ™ uses zinc polyitaconate technology to permanently break down malodor molecules, delivering true odor elimination with no fragrance, no residues, and no masking required.
2. Phthalates
Phthalates are the hidden bad actors in scented products. Used to help synthetic fragrances last longer on surfaces and fabrics, phthalates don't appear on ingredient labels, making them nearly impossible for consumers to detect. They are linked to hormone disruption and reproductive issues, and are a particular concern for children and pregnant women.
The most effective way to eliminate phthalate exposure in your home is to choose fragrance-free products. If odor control is the goal, look for true odor neutralizers like Itaconix ONZ that don't rely on synthetic fragrance to mask smells.
3. Preservatives
Traditional chemical preservatives like parabens, methylisothiazolinone (MIT), and formaldehyde-releasing preservatives (FRPs) are used to extend the shelf life of liquid cleaning products — but they're associated with skin sensitization, allergic reactions, and, in the case of formaldehyde-releasers, potential carcinogenicity. Parabens in particular have been flagged as endocrine disruptors, or chemicals that interfere with hormonal signaling.
Look for products that are transparent about what's in them and why, and that don't rely on a long chain of additives just to keep the formula intact on the shelf.
4. Dyes
Synthetic dyes give cleaning products their familiar blue, green, or purple hues, but that color serves no functional purpose. Dyes are purely cosmetic, and many synthetic colorants are derived from petroleum and have been flagged for skin irritation and potential toxicity. They offer no cleaning benefit and add an unnecessary chemical burden to both users and waterways.
When shopping for cleaning supplies, look for products formulated without added dyes. True performance doesn’t need to hide behind color.
5. Phosphates
Phosphates have long been used as builders in detergents to soften hard water and boost cleaning power, but their environmental record is damaging. When phosphates are washed down drains and enter waterways, they trigger eutrophication: a process where excess nutrients fuel explosive algae growth. The resulting algal blooms block sunlight, deplete oxygen, and create aquatic "dead zones." Many countries and U.S. states have already restricted phosphates in laundry and dishwasher detergents for this reason, yet they still appear in some formulations.
This is exactly the kind of problem that better ingredient technology and formulation chemistry can solve. Itaconix® TSI® polymers are plant-based and biodegradable, delivering superior scale inhibition and water conditioning, and enabling the complete removal of phosphates and phosphonates from detergent formulations without sacrificing performance.
6. Acrylates
When phosphates were restricted, many formulators turned to acrylate-based polymers like polyacrylic acid as replacements. The problem? They traded one concern for another. Polyacrylic acid-based polymers have been found to be non-biodegradable, meaning they persist in the environment long after they've left your washing machine. Some acrylate compounds have also been classified as possible human carcinogens by the EPA.
Itaconix TSI ingredients replace acrylates without this trade-off, delivering the same scale inhibition and dispersion with plant-based chemistry and improved biodegradability. It's a case where the safer ingredient is also the more effective one.
7. PFAS
Per- and polyfluoroalkyl substances — better known as PFAS or "forever chemicals" — earned that nickname because they resist breakdown in both the environment and the human body. They appear in some cleaning and stain-resistant products and have been linked to a troubling range of health outcomes: increased risks of certain cancers, reduced immune function, developmental delays in children, and decreased fertility, according to the EPA.
PFAS are not essential to cleaning performance. The European Chemicals Agency has proposed regulating them as a class, and advocacy groups note that manufacturers already have viable alternatives. This is one ingredient category where no level of exposure is acceptable.
8. Optical Brighteners
Optical brighteners don't clean — they deceive. These synthetic chemicals work by absorbing UV light and re-emitting it as visible blue light, creating the illusion that your laundry is whiter and brighter than it actually is. They accumulate on fabric fibers over time, putting them in ongoing direct contact with skin — a concern especially for those with sensitivities, babies, and children. They also biodegrade slowly, escape wastewater treatment, and can accumulate in aquatic ecosystems, with studies suggesting links to reproductive toxicity and developmental concerns.
Plant-based polyitaconate ingredients, used in tandem with enzymes, achieve genuine soil removal — no optical illusion required. When the chemistry is doing its job, there's nothing to hide.
9. Chlorine Bleach
Chlorine bleach is one of the most common cleaning agents in the home — and one of the most reactive. It can generate toxic byproducts, including chloroform and other organochlorines, when it reacts with organic matter or other cleaning chemicals. It irritates the respiratory tract, skin, and eyes, and is particularly hazardous in poorly ventilated spaces. For those with asthma or chemical sensitivities, bleach exposure can be acutely harmful.
Oxygen-based bleaching agents such as sodium percarbonate deliver effective whitening and disinfection without the chemical hazards of chlorine. When used with polyitaconates for improved soil redeposition, and enzymes for stain and soil removal, the result is cleaner, brighter fabrics without the safety concerns.
The Bottom Line
There's a pattern across this list: many of these chemicals exist in products not because they're necessary, but because they were the conventional answer before better technology existed. That technology now exists.
Itaconix TSI and Itaconix ONZ are plant-based, biodegradable polymer ingredients that replace multiple traditional chemicals with a single safer alternative that delivers the same or better results. Fewer chemicals in the formula means fewer chemicals in the environment, and no compromise on performance.
This spring, demand more from your products. Look at the labels. Ask questions. And know that the best formulations don't rely on a long list of chemicals – they rely on carefully chosen ingredients that are safer, more effective, and built for a cleaner future.
