Bathroom

ParabensPhthalatesPFASVOCs

The bathroom is the room where most personal care products are applied daily, making it a significant source of ongoing chemical exposure. Unlike food contamination, skin absorption of parabens, phthalates and synthetic fragrance bypasses the liver's initial detoxification step, delivering chemicals directly into circulation. The average person applies 9 personal care products before leaving the house, each containing a cocktail of synthetic ingredients.

What to look out for

Conventional shampoo and conditioner

Contains: Parabens, Phthalates, SLS
High
Why it matters

Most mainstream shampoos contain methylparaben or propylparaben as preservatives, phthalates as fragrance carriers, and sodium lauryl sulphate as a foaming agent. Applied to the scalp, a highly vascular area, absorption is significant.

The swap

Paraben-free, fragrance-free or essential-oil-scented shampoo

Brands like Attitude, Acure and Rahua offer certified clean formulations. Check ingredients via the EWG Skin Deep database before purchase.

Critical
Why it matters

Leave-on products applied to large body surface areas carry the highest dermal absorption risk of any personal care category. Parabens in body lotions have been directly detected in breast tumour tissue in research studies.

The swap

Fragrance-free lotion with clean preservatives, or pure plant oils

Unrefined coconut, jojoba or shea butter contain zero synthetic ingredients. For a lotion, look for vitamin E (tocopherol) as the preservative instead of parabens.

Conventional deodorant and antiperspirant

Contains: Parabens, Aluminium compounds, Synthetic fragrance
High
Why it matters

Applied to underarm skin close to breast tissue, deodorant ingredients absorb readily. Parabens and aluminium salts have both been detected in breast tumour samples, and the underarm area's proximity to lymph nodes raises particular concern.

The swap

Aluminium-free and paraben-free deodorant

Brands: Wild, Corpus, Routine, or Nuud. Expect an adjustment period of 2 to 3 weeks as your body recalibrates.

Vinyl shower curtain

Contains: Phthalates, VOCs
Medium
Why it matters

New vinyl shower curtains off-gas phthalates and VOCs. The distinctive new shower curtain smell is these chemicals volatilising. Heat from shower steam accelerates the release. Studies have measured VOC spikes lasting weeks after installation.

The swap

PEVA-free fabric shower curtain or glass shower door

Organic cotton or linen shower curtains are the cleanest option. Some PEVA curtains are marketed as PVC-free but still contain plasticisers. Glass doors eliminate the issue entirely.

Dental floss (PTFE-coated brands)

Contains: PFAS
Medium
Why it matters

A 2019 Silent Spring Institute study found that women who regularly used Oral-B Glide floss had significantly higher blood levels of specific PFAS compounds. The PTFE coating is the source.

The swap

Silk floss or plain nylon floss without PTFE coating

Brands: Radius, Lucky Teeth, or any floss that does not list PTFE or polytetrafluoroethylene in its ingredients.

Synthetic fragrance products (perfume, body spray)

Contains: Phthalates, synthetic musks, VOCs
High
Why it matters

The word "fragrance" on an ingredient list can represent a blend of dozens of undisclosed chemicals. Phthalates are used as fixatives and carriers. Synthetic musks accumulate in body fat and have been detected in breast milk.

The swap

Products scented only with essential oils, or fragrance-free

Brands using full ingredient transparency: Phlur, Ellis Brooklyn, or any product certifying fragrance ingredients through EWG Verified.
