Why cleaning products do not have to disclose ingredients
The specific ingredients to avoid
When the Huberman Lab audience put questions to Dr Shanna Swan on X, several specifically asked about household cleaning products. Do soaps, body wash, cleaning sprays and floor cleaners contain endocrine disruptors? And what can you use instead?
The short answer is yes, many conventional cleaning products contain compounds that either disrupt hormones directly or carry them as hidden ingredients. The slightly longer answer is that this is easier to address than most people expect.
Why Cleaning Products Do Not Have to Disclose Their Ingredients
Unlike food and cosmetics, household cleaning products in the UK and EU are not legally required to disclose every ingredient on the label. They must list certain categories of ingredients above a threshold concentration, including allergens and preservatives, but the full formulation can remain proprietary.
This means that synthetic fragrances, which as covered in our Beauty and Skincare page can contain hundreds of undisclosed compounds including phthalates, are routinely present in cleaning products without appearing meaningfully on the label. The word fragrance or parfum on a cleaning product label carries the same legal loophole as it does in personal care products.
The exposure route with cleaning products is primarily inhalation rather than skin absorption. When you spray a surface cleaner, you aerosolise the product and breathe it in. The lungs are a direct and efficient route into the bloodstream, making airborne chemical exposure from cleaning products potentially more significant than it might appear.
The Specific Ingredients to Avoid
Synthetic Fragrance
Listed as fragrance, parfum or perfume. Can contain phthalates, synthetic musks and other hormone disrupting compounds without disclosure. Present in most mainstream cleaning sprays, laundry detergents and fabric softeners.
Triclosan
An antibacterial compound found in some soaps, body washes and household cleaners. Classified as an endocrine disruptor and banned from personal care products in the EU and US, though it may still appear in some household products. Look for it specifically on ingredient lists.
Quaternary Ammonium Compounds
Also called quats, these are disinfecting agents found in many surface cleaners and fabric softeners. Research published since 2020 has linked them to reproductive harm in mice at concentrations comparable to household use, though human studies are limited. They appear on labels as ingredients ending in ammonium chloride.
Optical Brighteners in Laundry Products
These synthetic compounds make fabrics appear whiter under UV light. They are not rinsed out fully and remain in fabric fibres against the skin. Some have been identified as endocrine disruptors in animal studies.
Clean Alternatives That Actually Work
The good news is that most household cleaning tasks can be handled effectively with a small number of simple, genuinely clean ingredients.
A 50/50 mix of white vinegar and water in a spray bottle cleans most hard surfaces effectively, cuts through grease and has natural antibacterial properties. Add a few drops of an essential oil if you want fragrance. Inexpensive, plastic packaging free if bought in glass, and completely free of endocrine disrupting compounds.
Effective for scrubbing surfaces, deodorising, and tackling limescale when combined with vinegar. Available cheaply in most supermarkets in cardboard packaging.
Brands that fully disclose their ingredient lists and use plant derived surfactants rather than synthetic fragrances and quats. Look for fragrance free options or those scented only with named essential oils. The Environmental Working Group rates household cleaning products on their database at ewg.org which is a useful reference.
Fabric softeners in particular are worth replacing entirely, since they are designed to leave residue on fabric fibres and typically contain high concentrations of synthetic fragrance and optical brighteners. White vinegar in the fabric softener drawer works as a natural alternative that softens fabric without leaving chemical residue.
Can Hydrogen Peroxide Replace Bleach?
This was a specific question raised in the Huberman Lab audience session, and Dr Swan referenced hydrogen peroxide as a cleaner alternative to bleach for disinfection purposes.
Three percent hydrogen peroxide solution, the same concentration sold in pharmacies for wound care, is an effective disinfectant against most common household bacteria and viruses. It breaks down into water and oxygen after use, leaving no chemical residue. It is considerably less toxic than bleach and does not produce the chlorine gas fumes that bleach can generate when accidentally mixed with other cleaning products.
For most household disinfection purposes, three percent hydrogen peroxide is a genuinely effective and cleaner alternative to bleach. It is worth noting that it can bleach coloured fabrics so should be used carefully on surfaces that might come into contact with clothing or soft furnishings.
The simplest starting point is to replace your current multipurpose cleaning spray with a DIY white vinegar and water mix, swap your laundry detergent for a fragrance free plant based alternative, and stop buying fabric softener entirely. Those three changes alone remove the majority of endocrine disrupting exposure from a typical cleaning routine.
