PET Bottles and C2 Green Tea

Here are answers to Frequently Asked Questions regarding C2 Green Tea and PET Bottles.

What are the steps being taken by the company to ensure the safety of consumers patronizing C2 drinks?

All raw and packaging materials that go into the production of C2 undergo strict sampling, inspection and testing according to international test methods to make sure they all pass the standards of quality and safety before use. The process and facilities are designed by global players according to international standards. All materials, finished products and the plant facilities are audited regularly and approved by the Bureau of Food and Drugs.

PET is the most widely recycled plastic. Does the company re-use C2’s PET bottles?


Study shows that repeated washing and rinsing weakens the plastic, enabling carcinogens to leak into the PET bottles’ contents. Do you plan on putting “Please crush after use” on C2 PET bottles?

This is a hoax. Studies/reviews conducted by the US FDA and other institutions indicate that reuse of PET bottles is safe provided that washing and sanitizing is adequate before refilling to remove previous microbial and chemical contaminants.

Does the company have labels on the C2 PET bottles warning people of reuse, which may cause health hazards?

No. As long as washing and sanitizing of PET bottles is adequate prior to refill, reuse is generally safe.

A study also shows that liquid contents in PET bottles should not be more than a week and the PET bottles should be kept away from heat. Is this applicable to C2 drinks? Why?

This is a hoax. This is not applicable to C2. Migration studies conducted by the US FDA and other international scientific institutions do not support this claim as long as PET is used under the conditions of use specified by regulations.

Why can’t the company use glass bottles for its C2 drinks instead?

PET is more convenient, cost effective, and shatter-resistant than glass.

Is PET bottle safe?

The US Food and Drug Administration (FDA) approves polyethylene terephthalate (PET) for food and beverage applications. This material is widely used in the global food and beverage industry.

What’s wrong with re-using PET bottles? Is there a risk in re-using PET bottles?

First, C2 is using virgin bottles only. However, after consuming your favorite C2, you may reuse the PET bottles and this is generally safe based on the evaluations done by the US FDA. If there is any risk at all, it is when the bottled is refilled with hazardous chemicals and reused again as food/beverage container, where contaminants can come from the chemicals; or when the empty bottle is not adequately/properly cleaned and sanitized before refilling.

Is there DEHA (diethylhexyl adipate) migrating from the PET bottles to the product? Is DEHA carcinogenic?

1. DEHA is not a raw material, by-product, or decomposition product in PET manufacture so it cannot leach out from the PET bottle since it is not there in the first place.

2. This DEHA topic came from a master’s thesis of a University of Idaho student, which was published without peer review. Experts suspect that DEHA, which is a common plasticizer, may have come from the laboratory and could have contaminated the work of the student.

3. Even if present, DEHA is NOT a human carcinogen based on the evaluations of the US Occupational Safety and Health Organization (OSHA), National Toxicology Program (NTP), Environmental Protection Agency (EPA), and the International Agency for Research on Cancer (IARC). It is even allowed by the US FDA for food contact applications.

Is hot-filling causing chemicals to migrate from the PET bottle to the product?

PET bottles can be hot-filled based on conditions of use for PET bottles (US CFR 21 Part 177), which requires a maximum fill temp of 250 deg F. C2 is filled way below this temperature.

What does the number at the bottom of the bottles mean?

The number at the bottom refers to the plastic identification number and this is generally useful in the sorting of used bottles/materials for recycling purposes. These numbers are:

1 – PET, polyethlyene terephthalate
2 – HDPE, high-density polyethylene
3 – PVC, polyvinyl chloride
4 – LDPE, low-density polyethylene
5 – PP, polypropylene
6 – PS/PS-E, polystyrene / expanded polystyrene
7 – OTHER, resins or multi-materials

“Anything below 5 is hazardous” is a hoax; all types of plastics are allowed by the US FDA under specific conditions of use of which C2 follows in the case of PET.

Are PET bottles safe to recyle?

The technology for safe recycling of PET into bottles, clothes, etc., is available but we do not use recycled PET bottles for C2. C2 uses only newly molded/virgin PET bottles.

Is it true that the C2 process of brewing and bottling on the same day will release a carcinogenic chemical that is a health hazard?

No. There is no relation between C2 brewing and bottling on the same day, and the migration of chemicals from bottle to product.

  1. i suggest to answer the issue on the news or have a statement because some people believe that it’s true. Many of my friends also received the text message regarding the PET bottle. And some of them don’t buy C2 green tea anymore. I hope you you give priority regarding this matter bec. not everybody have time to search on the internet.

    [From the Admin] Thank you! I’ve forwarded your suggestion to the URC Customer Care group. Jojo Robles of the Manila Standard Today wrote about this issue in his column last August 28, 2006: Killer Tea–Not!

  2. All these PET scare is just concocted by the competitors to try to reduce the sales of C2. and as usual, majority of the filipinos will first believe than to think about this, remember the text messages of a tsunami coming to some remote philippine island last year?

    filipinos are gullible

  3. could you please explain the meaning of the number inside the triangle made of 3 arrows in each label of these plastic bottles? i noticed that these numbers vary on different products. on the other hand, other labels of plastic bottles have the triangle but do not have a number inside.


    [From the Admin] Hi Lilibeth! Those numbers refer to the plastic identification number and this is generally useful in the sorting of used bottles/materials for recycling purposes. You’ll find the details on this page.

  4. i was researching about this PET scare because some of my friends stopped drinking C2 and from re-using these bottles (#1) after learning that these can cause cancer. It was even featured in a morning tv program. we used to buy C2 in boxes and i reduce my c2 consumption in half because of this issue.
    thanks for this information. now i can drink c2 again without the hesitation and i can assure them that it is safe

  5. With regard to the numbering, which is representative of the different types of plastic materials. Shouldn’t it always indicate “1” for PET since it’s a PET bottle after all. Why have the rest?

    [From the Admin] Hi Bryce! Yes, PET bottles (e.g., C2 bottles) will show the number “1.” The other numbers mentioned above are for non-PET bottles. The other numbers were shown to provide context for the statement: “‘Anything below 5 is hazardous.’ is a hoax.”

  6. what is the meaning of code beside the expiration date of c2 when i bought c2 at sm, it indicates c1, c4, but when i buy c2 at the sidewalks vendor it indicates there is p2 is it fake?

  7. yes hello!
    i have this comment cause i love c2 so much..but lately i found out that the taste of c2 now is not as good as before.Its so sweet as in SWEET, that sometimes I need to add a water just to taste it better…well i guess theres something going wrong but of course i don’t know…i really miss the taste of real c2..i really miss.
    thanks..hope for your immediate action..

  8. i’d like to thank the URC management for having this general information about pet bootles. Actually although im working as an accountant and markeitng officer in ourcompany, im also managing my own business. I have a food business near school and C2 products are very saleable, but because of the bad issue its slow down the sales. Since im also concerned in health aspects of our customer didnt sold C2 anymore. Now, after your company clarifying the issue and after knowing that its not dangerous to health, rest assured that i will offer your products again.
    Thanks alot!!!

    [From the Admin] Thank you for the kind words, Ms. Annielee. I’ll forward your comment to the URC Customer Care group.

  9. i would like to read the specific documents from the u.s. fda and other international agencies on which you base your claims. please provide a list of all documents that we can personally refer to. as an environmentalist, i am for reuse and recycling. but i would like to check the sources of your claims first.

  10. would like to have a list of prices of c2 and the variety of products. thank you .

  11. im so glad u have made this best beverage in the country;im a sub dealer of our best product c2.i can sold 150-200boxes of c2 to all my 20 active retailers,including grocery store,canteen,vendors,in pasay. i hope that someday i can sold 500boxes this coming months.

  13. hi! i would like to comment on the company not reusing the PET bottles of C2. the country is suffering from lots of wastes. we even have problems regarding proper waste disposal and waste management. not all consumers keep the bottle for re-use and instead dispose them immediately because keeping them in their own homes consume storage space where they could possibly store things which are more important than these bottles. well, if the company keeps on using newly molded or virgin PET bottles, most of them just end up in land fills, left unrecycled and unreused. How can this issue be resolved?

  14. what is the real unique selling proposition of C2???
    What is the meaning of the brand mark???

  15. You mentioned in your article that you fill your product in PET plastic bottles with a temperature of way below 250F (121C)?
    Do you have a ‘showering stage’ or a ‘pasteurization process’ where in the temperatre is pulled down/lowered – prior to filling?
    May I know what temperature of this?

  16. i am setting up 2 factories and require a safe bottle,containers for the product but to export to europe i need the bottles ,containers to be registered with the european pharmacopeia can you help regards derek bates

  17. i was onced a mold maker in some plastic companies here in the philippines, what i know is that pet bottle is for drinking, others like:

    HDPE, high-density polyethylene, LDPE, low-density polyethylene, PP, polypropylene is for shampoo and skin lotion packaging…
    PVC, polyvinyl chloride is for facial astringents, etc

    somehow, other countries re-uses pet bottles in some applications… search the net… the only problem is garbage collection in our country andt its very poor . estimated 5% will be brought in some plastic companies to be clean and granulated again….

    pet bottles exposing to the sun is not also dangerous… in indonesia they make their water exposed to sun using used pet bottles… there is a masteral thesis from sudan that granulated pet bottles can be a substitute for sand as construction materials and good for insulation. why? because sand or white sand by its own processes can produced silica and it will be added to produce glass material..

    another example that some teachers used pet bottle as graduated cylinders due that they were not funded by the education department for their facility improvement.

    as consumers, we must advocate the one R of the 3Rs, reuse.. people must educate themselves about this….

    well its a companies’ responsibility when it comes to manufacturing of their product… their facility must be sterile and they must know their food and drink chemistry…. packaging units where checked not only from its appearance. Supermarket owners must checked also the expiration dates of their product and must not be sold if one-two months expired…

    for your information

  18. when you bottle Iced tea what temperature should be used And what is the highest temperature that you can put into the bottle?
    Thank you,

  19. I just got a C2 bottle and there is no symbol anywhere with the arrows and number. Please add this to the 1 liter bottles.

    Also about creating the hoax about PET bottles by other companies….
    They would also have losses because PET bottles is so widely used. Reading in wikipedia that PET is impact resistant, this would explain why when i accidentally dropped a C2 bottle half full off the 2nd floor of our house, it did not even dent……

    Reaction also bout the taste of C2, it seems to be sweeter, way more sweeter than the old version, but still tastes good.

    UR, keep up the good work!
