PP Bottle is Safe

By • Apr 18th, 2009 • Category: Product Knowledge

Plastic baby bottles have received extra attention recently as research came to light showing many popular models leach Bisphenol-A (BPA), a suspected endocrine disruptor. While there’s little scientific data on the effects of BPA on humans, studies on animals suggest that it may not be safe, and have linked BPA to a range of cancers, early on-set puberty, obesity, and type-II diabetes.

Problems arise when the chemical leaches out of the bottle or container into the liquid or food that’s in contact with the plastic. If your baby drinks from one of these bottles — or consumes formula packaged in one of these cans — it’s possible that he’s also getting a dose of BPA. The amount of the chemical that leaches depends on the type of cans, the temperature used to sterilize the formula after the can is sealed, and the food itself.

Many parents hence believe that they should consider steps to reduce infants’ exposure to BPA when possible. When it comes to infants and small children, yes,  it is always “better to be safe than sorry”.

Why using a PP Breastmilk Bottle? new-pp-bottle500

The plastic of concern, polycarbonate (plastic #7), is used by several manufacturers for the baby bottles, but there are safer alternatives.  While we recommend using glass bottles when possible, we realize that plastic is the most convenient option for many moms. All existing research maintains that polypropylene (PP or plastic #5) is safe and still the best and economical option for storing the mothers’ precious breastmilk. The PP plastic bottles are BPA-, phthalate-, and PVC-free.

While all of us and our children are regularly exposed to low levels of a myriad of chemicals, including BPA, there are some measures we can take to avoid at least some of these exposures. A good general principle is to avoid unnecessary exposures to chemicals in your food and water and to choose options that convey lower exposure whenever possible.

Tips and Guidelines

If you’re concerned about your baby’s exposure to BPA, his baby bottle or formula container is an important source to address. Here are some concrete things you can do that shouldn’t hurt and might help:

  • Breastfeed your baby. This one step will avoid BPAs in both bottles and formula can liners.
  • If you bottle-feed your baby, use glass baby bottles or those made from BPA-free plastic instead of polycarbonate bottles. If you’re using plastic, look for bottles labeled “BPA free” or buy bottles made of polypropylene, which are usually opaque or colored rather than clear.  Polyethersulfone or PES, a high resilient thermoplastic polymer with low protein retention, is also increasingly available. It’s safe and meets all the stringent requirements of US FDA standard for baby feeding bottle application.
  • Get rid of polycarbonate baby bottles and sippy cups that turn cloudy or are scratched or cracked. Worn bottles may leach BPA more easily.
  • Don’t put polycarbonate bottles or sippy cups in the microwave. Some studies show that high heat can cause more leaching of the chemical. When necessary, warm the bottle or cup by placing it in a pan of hot water.
  • Whichever type of bottle you use, be sure to carefully follow the manufacturer’s instructions for preparing and heating the formula. Formula needs to be gently warmed, not boiled. (In addition to causing more leaching, hot formula can burn your baby’s mouth and cause nutrients in the formula to break down.)
  • Use powdered rather than liquid formula. While both liquid and powdered formula cans contain BPA, powdered is a safer choice. The Environmental Working Group has calculated that babies fed reconstituted powdered formula probably receive eight to 20 times less BPA than those fed liquid formula from a metal can.
  • When buying plastic bottles, look at the bottom of the containers. Avoid those labeled 7, as they may contain BPA. (Those labeled 3 may contain phthalates and those labeled 6 may contain styrene, so you’ll want to avoid those numbers, too.) Use only containers coded 1, 2, 4, or 5.
  • Don’t put plastic dishware or containers in the microwave or dishwasher, and don’t wash them with harsh detergents. High heat and abrasive cleansers can damage the plastic, which will make it leach more.

The above information is researched and extracted from BabyCenter and Environmental Working Group websites.

  3. Hi Meili,

    Thank you for asking.

    PP temperature resistance is up to 120 degree Celsius, so we recommend you not to sterilize it using electric sterilizer. Follow the instructions on the packaging box, you may clean it using a baby safe liquid cleanser and then immerse it in hot water (remember, NOT boiling water) for 10-15 minutes after each use.

    Hope this helps.

    Hi Cammy

    boiling water – we are referring to water that could be still in the process of boiling and/or the temperature is at/above the water boiling point

    hot water – we are referring to water with temperature that is considered hot for a normal person (but unsafe for consumption yet) but it is not at or above the boiling point of the water. For example, leave the boiled water cools down a while but still hot enough to clean the bottles.

    hope this differentiation helps.

    Hi Alya,

    yes, of course it is safe for feeding as well, as it is PP material which is BPA free. On the cleansing part, please refer to the cleaning method we have stated on the box. For better results, you may want to clean it with our Baby Safe Liquid Cleanser.

    thanks for the enquiry.

  5. Hi,
    I just bought the bottles but I’m confused. It says that I have to use hot water to rinse and clean the bottles but does that mean that I don’t have to sterilize them? I have a steam sterilizer and am wondering if I can sterilize the bottles using steam….on the box it says to avoid boiling water, sterilizer tablets and high heat..so does it mean that I cannot sterilize them using stea, boiling or using sterilizing tablets?
    hope you’ll reply soon. thanks.

    Hi Zeti,

    Thanks for your enquiry.

    As widely recommended by many, PP material is actually encouraged to avoid boiling water, sterilizer tablets and high heat as stated on the box due to its composition, as compared to PC material which contains BPA that makes them more sustainable to heat & chemicals. But PP is BPA-free, so you don’t have to worry about the danger of BPA.

    Nevertheless, there are also few grades of PP (harder in material for easier differentiation), which some of customers do sterilize using a steam sterilizer and find the PP products is totally Ok and has no “softening” feel. In fact, we do have some customers tried to sterilize on our PP breastmilk bottles, and so far they are fine with it. Perhaps you may want to check the sterilizing cycle of your sterilizer, try not to expose PP material to a sterilizing cycle that is too long.

    For safer choice, we would however advise our customer to use Bumble Bee Baby Safe Liquid Cleanser (chemical free) to cleanse the PP bottles totally and follow the stated cleaning procedures. And these steps when followed properly are indeed enough to keep a bottle clean for usage. If you still would like to see how the bottle reacts with your sterilizer, you may try to sterilize one bottle and see how the bottle reacts yourself, and decide whether you want to continue doing so.

    Do remember to replace the bottles every 6 months or when worn effects are shown, whichever is earlier.

    Hope this helps.

    It really depends on individual babies which time is best for them to start with baby walker, and we are not in the best position to advise you on this. Maybe you can search around (google it) and see if there is any guidance available online? Or, you can also consult your baby’s pediatrician. Check out this site, a guide link, see if this helps you?

  10. Hi, I would like to know what the differences between Polycarbonate Bottle (PC) and Polyproplyene (PP) Bottle.

    [Reply]

    admin Reply:

    Hi Chong,

    the main difference between PC and PP is: PC contains BPA, but PP is BPA-free. That means PP bottle is a safer bottle to use than PC bottle, because PP won’t release BPA which is not good for the human body.

    Hope this helps. :)

  12. Hi,

    1. I just want to confirm again if we shouldn’t sterilize these bottles in sterilizer because the salesgirl that i approached told me we can sterilize these bottles.

    2. Can these bottles be fit with Avent pump, Medela pump, Ameda pump and Spectra pump?

    [Reply]

    admin Reply:

    Hi Winnie

    thanks for your inquiry.

    1. PP material can sustained heat up to 120°C, it is quite near to the normal sterilising point, that’s why in practice we do not recommend it to be sterilised. It is not like the hard PC plastic which can sustain higher degrees. However, you can just follow the instructions on the packaging box, you may clean it using a baby safe liquid cleanser and then immerse it in hot water (NOT boiling water) for 10-15 minutes after each use. These steps are sufficient to keep the bottles clean.

    2. Our PP bottle is standard neck, so can fit into all breast pumps that are using standard neck size, such as Medela and Spectra. Avent is wideneck, so we couldn’t fit in that one. As long as it is a standard neck breast pump, our bottle will be able to fit in.

    Hope this helps. :)

  14. Hi, im getting Ameda lactaline breastpump and also interested in getting bumble bee bottles for breastmilk storage.

    I have few questions here:
    1) Do i need to get a electric steriliser to clean the bottles? Is it safe to clean using steriliser?
    2) Can i feed my baby using the milk storage bottle? I just have to change the teats is it?
    3) How do i reheat the breastmilk? Does bumble bee has any warmer?

    Thanks.

    Hi LSL,

    thanks for the message. For your questions, pls see our comments below.
    1) It is advisable to invest on an electric steriliser to clean the bottles. For our storage bottles however, you can also follow the cleaning instructions on our packaging box to clean the bottles if you do not own an electric steriliser.

    2) You can feed your baby directly from the milk storage bottle, just change the teats will do. However, it will be more practical if you use separate feeding bottle and storage bottle, as you will need more bottles on storage purpose.

    3) We do not have a warmer at the moment.

    When heating up breastmilk, take note of the following:

    Breast milk should never be thawed in a microwave oven.

    Breast milk should be kept in the refrigerator while thawing. Milk can also be run under some warm water for a few minutes.

    Breastmilk should also never be refrozen. You should not reheat breast milk more than twice, reheating breast milk can cause the growth of harmful bacteria and can make baby sick. When heating breast milk, never bring the breast milk to boiling point as this will destroy its quality.

    Previously thawed breast milk can be kept in the refrigerator for 24 hours. After breast milk has been thawed, it should be used within a day or two at the latest.

    Hope this helps.

    Hi Veronica,

    for plastic bottle, it is advised to change every 6 months, or signs of worn out appear, whichever is earlier. If you are using glass bottle, you can use until it breaks, and glass contains no chemical (unless it is not pure glass). However, please do change the teats around 3 months.

    Hope this helps.

    sorry for late reply. Yes, you may sterilize PP bottle if necessary. But as PP bottles are softer plastic, we would normally advise you to follow the cleaning instruction as stated at the back of the packaging box.

    Hi

    We will answer under each question, for easier reading. Hope we do help.

    1. How can we recognize whether the bottle is PP 5, if it didn’t state in the packaging? Is that it will show at the bottom of the bottle by the number ‘5’ is inside the triangle, and the words ‘PP’ is write under it?

    BB: Yes, normally there will be labels at the bottom. Number 5 is PP bottle. Generally PP bottle is more milky in colour, it’s not totally transparent.

    2. All the PP 5 bottle is BPA-free?

    BB: Yes.

    3. What is the temperature resistance of PP 5 bottle?

    BB: 120 degree Celsius.

    4. Can I rinse the PP 5 bottle or Bumble Bee milk storage bottle with hot water ( just boiling, 100 degree Celsius ) , or have to wait the water temperature reduce to a lower temperature?

    BB: You can rinse it with boiled water, as its resistance is 120 degree Celsius.

    5. How to sterilize the bottle if I didn’t have the sterilizer?

    BB: Immerse the bottles in hot water for 15 minutes.

    6. Need I immerse the feeding bottle or storage bottle into the boiled water (room temperature) all the time?

    BB: You don’t have to. After immerse it in boiled water, you should take it out and dry it, cap back and keep in a container with lid to prevent further contamination.

    7. If I pour the hot boiling water into an Indian pot and let the bottles immerse into it. The water temperature will slowly reduce from 100 degree into room temperature. Is it the proper way?

    BB: Not really sure what is an Indian pot. But please refer to question 6 for the handling part.

    8. I found that some of the PP 5 storage bottle is soften, can I still rinse it with hot water (just boiling)?

    BB: PP plastic is generally softer, but their resistance level should be around 120 degree Celsius unless otherwise stated…
