She got worried about the news regarding dangers with baby feeding bottles. The migration of Bisphenol A substance to baby milk formula. The feeding bottles in question are those with number 7 recycling symbols or polycarbonates.

We noticed that most of our baby’s feeding bottles have recycling code of number 7. Some of them have recycling code of number 5 and some have no recycling symbol. We started to avoid those with code 7 and no code bottles. Identity of no code bottles is unknown. Its not safe to gamble with unknown bottles?

Through research, I discovered the recycling symbol number 5 is polypropylene. A plastic polymer that is widely used for food industry. Unlike polycarbonate and other plastics, it is resistant to heat with a melting point of 160° Centigrade.  Water boiling temperature of 100° C has no affect on this plastic. It is popular for its resistance to chemical solvents, bases and acids.

Food applications of polypropylene containers are yogurt packages, syrup bottles, ketchup bottles, caps, straws, medicine bottles and other hot-packed food products.

Plus no reported health issues about polypropylene. So we decided to replace all our baby feeding bottles with this kind of plastic.

In buying feeding bottles, we always look for the number 5 recycling code.  Polypropylene is also softer than polycarbonate.

Avoid Feeding Bottles with Code 7, Bisphenol A?

I have a previous article about the possible side effects Bisphenol A. The substance combined in making in making polycarbonate resin –  for making food containers, such as returnable beverage bottles, infant feeding (baby) bottles, tableware (plates and mugs) and storage containers. The article is about Bisphenol A as endocrine disruptor, it may affect human reproductive systems.

The recent new from GMA7 was somewhat conclusive. The culprit chemical is bad fro growing child. It may also cause heart problems and diabetics. According to studies of University of the Philippines Institute of Biology, Bisphenol A causes low sperm count to rats. The animals under study also suffered smaller sex organs.

The troublesome substance may leach into baby milk formula if boiled for 20 to 30 minutes. The use of bottled mineral or distilled water in formula preparation avoids heating of bottles. However, baby feeding bottle sterilization involves dipping it in boiling water.

The use of Bisphenol A is prohibited  in most countries but not currently regulated in Philippines, the law that should stop its entry is still in pending review.

To avoid Bisphenol A, feeding bottles and other plastics with the recycling code of number 7 should be avoided.

Its too bad, almost all of my baby’s feeding bottles has number 7 code. I should replace them all immediately.

Possible Dangers of Bisphenol A (Plastic and Tin Can)

Authorities are studying the possible effects of Bisphenol A to human health. The said substance may interact with our hormone systems, the so called endocrine disruptor. Animals are proven to interact with endocrine disruptor but the link of Bisphenol A to human is not yet conclusive.

Bisphenol A (BPA) is a chemical that is mainly used in combination with other chemicals to manufacture plastics and resins. For example, BPA is used in polycarbonate, a high performance transparent, rigid plastic. Polycarbonate is used to make food containers, such as returnable beverage bottles, infant feeding (baby) bottles, tableware (plates and mugs) and storage containers. Residues of BPA are also present in epoxy resins used to make protective coatings and linings for food and beverage cans and vats. BPA can migrate in small amounts into food and beverages stored in materials containing the substance.

The use of Bisphenol A for packaging materials is regulated.

The Plastic Materials and Articles in Contact with Food (England) Regulations 2009 permit the use of BPA in the manufacture of plastic materials and articles intended to come into contact with food, provided that no more than 0.6 mg/kg migrates into the food.
