Are phthalates in soft plastic bath books safe for babies?
No. Phthalates are chemicals used to make plastic soft, and they are not safe for babies who often chew on their bath books.
What's actually in it
Soft plastic bath books are often made with phthalates. These are chemicals added to plastic to make it flexible and soft. Because these chemicals are not bound to the plastic, they can easily leak out when a baby chews on the book or when the plastic gets wet in the bath.
Many manufacturers use these chemicals because they are cheap and effective at creating that squishy texture. However, they are not stable. They move from the plastic into your baby's mouth and skin during playtime.
What the research says
A 2026 study in Sci Total Environ highlights the presence of these plasticizers in various plastic products. This peer-reviewed research confirms that recycled and soft plastic materials frequently contain a mix of phthalates and other additives.
The science is clear: these materials are not inert. They are designed to leach, meaning your baby is directly exposed to these chemicals during their daily bath routine. When you choose soft plastic toys or books, you are choosing products that are chemically engineered to shed their components into your home environment.
