Is it safe to buy sauces and condiments in plastic squeeze bottles?
Not ideal. Acidic or fatty sauces in plastic pull plasticizers over months of shelf life.
What's actually in it
Ketchup is acidic. Mayo is fatty. Mustard and hot sauce are both. All of them sit in plastic bottles for months, pulling plasticizers and microplastics into the sauce the whole time. Squeezing the bottle adds friction that speeds plastic particle release.
Most big-brand condiments are available in glass.
What the research says
A 2025 study in J Hazard Mater mapped phthalate intake across diets and identified sauces and condiments in plastic as measurable contributors. A 2025 study linked prenatal phthalates to slower infant neurodevelopment.
Buy condiments in glass jars when you can. Transfer squeeze-bottle sauces you love into a glass jar at home and dispense with a spoon.
