If you're new to sensory chew necklaces, these labels can be confusing. What do they actually mean, and why are they important?
In this guide, we'll explain the materials commonly used in sensory chew necklaces, what to look for when choosing one, and how material quality can affect your overall experience.

Why the Material Matters

A sensory chew necklace is designed to be chewed repeatedly, so the material needs to be durable, flexible and easy to clean.
Choosing a quality material can influence:
  • Comfort during chewing
  • Resistance to wear
  • Ease of cleaning
  • Everyday durability
  • Overall product quality
Rather than focusing only on colour or shape, it's worth taking a few moments to understand what the necklace is made from.

What Are Most Sensory Chew Necklaces Made From?

Most modern sensory chew necklaces are made from food-grade silicone.
Silicone is a flexible, rubber-like material that is widely used in products intended for regular contact with food and in many everyday household and baby products.
Manufacturers often choose silicone because it is:
  • Flexible
  • Durable
  • Comfortable to chew
  • Easy to clean
  • Available in different firmness levels
  • Resistant to everyday moisture
Its versatility makes it well suited to sensory chew necklaces designed for repeated use.

What Does "Food-Grade Silicone" Mean?

Food-grade silicone refers to silicone that is manufactured for contact with food and intended to meet relevant safety requirements in the markets where it is sold.
For consumers, this generally means the material is designed for regular food contact when used as intended by the manufacturer.
When shopping for a sensory chew necklace, look for products that clearly state they are made from food-grade silicone and provide transparent product information.

Understanding Common Material Labels

You may notice several material claims listed on product packaging or websites.
Here's what they commonly mean.

BPA-Free

BPA (Bisphenol A) is a chemical used in the production of some plastics.
Many quality sensory chew necklaces are labelled BPA-free, meaning they are manufactured without BPA.

PVC-Free

PVC (Polyvinyl Chloride) is a type of plastic used in many consumer products.
Many silicone chew necklaces are also labelled PVC-free, indicating they do not contain this material.

Phthalate-Free

Phthalates are chemicals that have been used to make some plastics more flexible.
Many quality chew necklaces are manufactured without phthalates and may be labelled phthalate-free.

Latex-Free

Some products also state that they are latex-free, which may be helpful for individuals with latex sensitivities.
Always refer to the manufacturer's product information if this is an important consideration.

Why Silicone Is Popular for Sensory Chew Necklaces

Silicone offers several practical advantages.

Flexible

It compresses slightly during chewing while returning to its original shape.

Durable

Quality silicone is designed to withstand repeated everyday use, although no chew necklace lasts forever.

Comfortable

Its slightly soft texture provides a comfortable chewing experience for many users.

Easy to Clean

Silicone can usually be cleaned with warm water and mild soap according to the manufacturer's instructions.

Available in Different Firmness Levels

Silicone can be manufactured in different firmness levels, allowing products to suit different chewing preferences.

Does the Material Affect Firmness?

Not directly.
Most chew necklaces are made from silicone, but firmness is determined by how the silicone is manufactured and designed, rather than simply the material itself.
That's why two silicone chew necklaces can feel completely different.
Factors that influence firmness include:
  • Silicone formulation
  • Pendant thickness
  • Shape
  • Overall design

Does the Material Affect Durability?

Yes, but durability also depends on:
  • Chewing habits
  • Frequency of use
  • Pendant design
  • Firmness
  • Proper care
Even high-quality silicone will eventually show signs of wear with regular chewing.
Inspect your chew necklace regularly and replace it if it becomes damaged.

How to Identify a Quality Sensory Chew Necklace

When comparing products, look for:
  • Food-grade silicone
  • BPA-free materials
  • PVC-free materials
  • Phthalate-free materials
  • Breakaway safety clasp
  • Clear care instructions
  • Manufacturer guidance
Buying from a reputable supplier can also provide greater confidence in product quality and support.

Caring for Silicone Chew Necklaces

Looking after the material helps maximise its lifespan.
Good habits include:
  • Cleaning regularly
  • Allowing the necklace to dry completely
  • Inspecting it for signs of wear
  • Replacing it if damaged
  • Storing it in a clean, dry place
