How To Wash Your Baby Bottle: Prevent The Releasing Of Bisphenol-A
In this particular posting I want to share about the safety method to minimize the released of Bisphenol A (BpA) to formula milk. In household work every step when you preparing the beverage in the baby bottle can contribute the leach of BpA. The laboratory research that estimate realistic releasing of BpA from baby bottle was conducted by Sandra-Biedermann-Brem and Koni Grob, we should consider these following scenarios:
- The baby bottle is sterilized by boiling water inside the bottle (by means of microwaves, as this is not practical in a pan) and, as this water is sterilized at the same time, it is used for preparing the beverage. Sterilization is often recommended to involve 5 minutes of heating, which in the experiment resulted in the release 0f 3-10 micrograms/l BpA. However, in household work this heating may easily be overdone and concentrations will be far higher then.
- Water is boiled outside the bottle and hot water or a beverage is poured into the bottle. It may even be kept warm by insulating the bottle for later use. Using water heated in a pan for 10 min, a BpA concentration of 6 micrograms/l was measured.
- Highest BpA concentrations (possibly exceeding 100 micrograms/l) are obtained by boiling water inside the bottle which has already been boiled before.
- Drying a polycarbonate with hard water or residues of washing solution at a high temperature in a dishwasher may liberate BpA on the bottle wall which is then redissolved in the beverage filled into the bottle. Such release seldom exceeds 10 micrograms/l.
- Preparing a drink according to the usual recommendations, for example by boiling the water in a pan, then adding milk powder and adequately cooled water to the bottle results in BpA release below 0.5 micrograms/l.
And here are the recommendation for parents in order to reduce your baby’s, your child’s, and your own exposure to BpA:
- Do not boil water to be used for preparing drinks in a polycarbonate bottle.
- Do not use harsh detergents or put bottles in the dishwasher. Instead, clean them with warm soapy water and a sponge. Scouring brushes can scratch the surface of the bottles and increase leaching rates.
- Avoid filling hot water or tea into polycarbonate bottle (not critical for milk and similar drinks).
- Avoid heating foods in polycarbonate containers, as BpA tends to leach faster with higher temperatures.
- Avoid use of infant formula brands in cans that use BpA as an epoxy liner (check in this site www.ewg.org/reports/infantformula).
- Cut back on consumption of canned foods and beverages to reduce exposure to BpA contamination from the interior coating of the container. Also avoid canned foods with higher fat content, which may have higher levels of BpA.
- Periodically changed your baby bottle, for example every 6 months.
- If you decide not to use polycarbonate bottles (hard, shiny, clear or tinted plastic, usually with a number 7 or “PC” on the bottom/underside), then you have to use glass or polypropylene bottle (the #5 plastic).
I believe cautionary action is necessary to help ensure the health and well-being of our baby in the present time or in the future. But, it will be better if BpA can be removed from products marketed to our baby.
