Arm & Hammer Laundry Detergent

⚠️ USE WITH CAUTION

Budget everyday laundry washing

Materials

Surfactants
Sodium carbonate
Optical brighteners
Fragrance

Common claims

Baking soda powered
Fresh scent
Clean and affordable

Concerns / watch-outs

Contains optical brighteners that stay on fabric and contact skin throughout the day
Standard fragrance concerns; choose the fragrance-free or sensitive skin version

Notes

Arm & Hammer's baking soda branding implies simplicity, but the regular formula adds synthetic fragrance and optical brighteners. The Free & Clear version is a meaningfully cleaner choice.

Cleaner alternatives

Downy Ultra Liquid Fabric Softener

⚠️ USE WITH CAUTION

Softening clothes and adding fragrance in the rinse cycle

Materials

Dihydrogenated tallow dimethylammonium chloride (quat)
Fragrance
Preservatives

Common claims

Softens and conditions fabric
Static reduction

Concerns / watch-outs

Quaternary ammonium compounds (quats) can sensitize the airways and skin with repeated exposure

Notes

Downy is one of the most frequently flagged laundry products in low-tox communities. The quat and fragrance combination is a double concern. Wool dryer balls are a straightforward replacement.
