Baby Bottle Nipple: 100% Natural Rubber

Hevea’s nipples are made from natural rubber sourced from the Hevea brasiliensis tree, not synthetic rubber made from oil. To create a more hygienic product, the nipples are made in one piece such that there are no openings or seams that can harbor bacteria.

Nitrosamine levels

Nitrosamines are various chemical compounds, some of which are carcinogenic, that can be found in treated drinking water, food, cosmetics, tobacco and rubber products. Some of the most carcinogenic and therefore subject to limits are N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA). In rubber products, they are formed during the manufacturing process and may be present in the final product. In the case of rubber nipples, nitrosamines can migrate into the saliva, milk or infant formula and then can be ingested into the body.

According to Hevea, “It is correct that nitrosamines are to be found in natural rubber, but Hevea passes all the test and regulations for pacifiers, which also test for the amount of nitromines. If the limit is too high it can be dangerous, but we have NOT detected any in our products, and we have them tested randomly.”

Hevea complies with European Standard EN14350 which applies to “Child Use and Care Articles – Drinking Equipment” and sets the nitrosamine limit at 0.01 mg/kg and the nitrosatable levels at 0.1 mg/kg.

Hevea complies with the FDA’s Compliance Policy Guidelines Section 500.450 which addresses Volatile N-Nitrosamines in Rubber Baby Bottle Nipples that sets the limit at 10 ppb for individual nitrosamines.

10 ppb is the same as 0.01 mg/kg.

Latex Sensitivity

Natural rubber is made from white sap, also known as latex, that is tapped from the rubber tree. In the tree’s latex, there are naturally occurring proteins that end up in the final natural rubber product that cause some people allergies, i.e. a latex allergy.

Hevea notes:

The processing of the latex to produce Hevea’s raw rubber products leaches out much of the latex protein. As a result, latex content in Hevea’s products is extremely low.

Even though no allergic reactions to any Hevea products have been received to date, users should note the potential for an allergic response to latex. If there is a known family history of latex allergy, or if you notice any symptoms that cause concern, or if your child has had a previous reaction to any other rubber products, stop use immediately and visit your medical practitioner. Addressing early symptoms may prevent more serious effects.

Allergy reactions to latex vary in severity with individuals, yet is usually not dangerous. Symptoms can include:

  • Sneezing or runny nose
  • Coughing
  • Rash or hives
  • Chest tightness
  • Shortness of breath

Always concerned with your child’s safety and creating products of the utmost quality, Hevea is supporting its suppliers in trying to find a way to improve rubber processing to reduce the potential for latex allergic reactions.


  • The rubber nipples are NOT microwave or dishwasher safe.
  • Prior to first use, sterilize by placing in boiling water for 5 minutes.
  • When sterilizing nipples in boiling water make sure that there is enough water in the pot to avoid damage to the nipple. Do not boil in pressure cooker.
  • For babies aged 0-3 months, sterilize rubber nipple prior to each use.
  • For babies aged 3+, clean before each use with warm water.
  • After cleaning make sure no water is left inside.


  • Prior to each use, check nipple to ensure it is not blocked up and pull it in all directions.
  • The anti-colic valve works by creating pressure equalization in the bottle so that baby does not swallow unwanted air during feeding. Tighten the ring securely, but do not squeeze flange or valve too much.
  • Replace nipples every 1-2 months or sooner if they show signs of wear and tear. Teething babies can tear the nipples.
  • Do not leave nipples in direct sunlight, near a heat source or sitting in a disinfectant for longer than recommended as it may weaken the nipple.
  • Never use nipples as a soother.
  • Screw thread and cap is dishwasher safe if placed on the top rack.


We should use our abilities to contribute to the greater good – and let our actions leave positive, green fingerprints, to preserve and protect the world we leave to our children.    – Terese Hoffeldt

Prior to founding Hevea, Terese Hoffeldt worked at Mars. Though one of the company’s five pillars is “Make a Difference,” she never felt like she was making much of one. She yearned to turn her passion for business and her desire to truly make a difference into something that would make a real positive impact.

Then her world changed. Just two weeks after giving birth to her daughter, Terese’s beloved mother passed away. Being at once blessed with life and confronted by death, Terese began to examine her purpose in life more deeply: What good would she do with her life? What legacy would she leave on this earth? Profoundly moved by her mother’s passing and fueled by wanting to make the world a better place for her daughter, Terese Hoffeldt founded Hevea.

In honor of her love for trees, Terese named her company after the rubber tree Hevea Brasiliensis. It is this tree which produces the natural rubber that serves as the foundation for Hevea’s product line. And in honor of future generations, she has ensured that Hevea is committed to environmental stewardship and the highest quality products they can make.

Hevea is deeply committed to environmentally-responsible business practices.

Natural Rubber

Hevea’s rubber product line is made of 100% natural rubber, which is biodegradable and a sustainable resource. Natural rubber has the ability to be broken down physically and/or chemically by microorganisms – usually requiring exposure to sunlight, air and moisture. Using natural rubber, rather than synthetic rubber made from oil, acts against climate change by increasing the number of trees and cutting back on the use of fossil fuels.

Malaysian Rubber Board

Hevea uses natural rubber tapped in Malaysia. They pay a percentage of the raw rubber costs to the Malaysian Rubber board, which in return hel
