Not all latex gloves look exactly the same. Some appear almost ivory, while others have a warmer, more yellow tone.

The shade isn’t random. It is influenced by several factors throughout the glove’s manufacturing process.

• WHITE

• IVORY

• WARMER YELLOW

What Contributes To The Changes In Colour?

01. NATURAL LATEX

Naturally occ

urring components in the rubber, such as proteins, lipids and pigments, can contribute to its colour and a warmer tone.

Natural rubber

contains various colour contributing substances, with carotenoids being an important contributor to its characteristic yellow colour.

02. WASHING & PURIFICATION

Removing colour contributing components during processing can result in a paler appearance.

This is supported by research showing that washing, centrifugation and purification can remove non rubber components and reduce the yellowness of natural rubber.

03. FORMULATION & CURING

The ingredients and curing conditions used to develop the glove’s strength, elasticity and durability can also influence its final shade.

Why Does Formulation Matter?

Rubber needs to be strengthened before it becomes a glove.

Vulcanisation creates crosslinks between rubber molecules, helping make the material stronger, more elastic and more durable.

The formulation and curing process can also influence the final appearance of the rubber

04. CHLORINATION 

Chlorination is a process that reduces the natural stickiness of latex, making gloves smoother and easier to put on. Gloves may be single or double chlorinated, depending on the surface properties required.

SINGLE → Inside treated

DOUBLE → Inside + outside treated

05. AGEING & OXIDATION

Over time, exposure to oxygen and other environmental factors can cause chemical changes in the rubber to become more yellow or brown.

Natural rubber can undergo oxidation and other discoloration reactions during processing and storage, contributing to yellow or brown colour changes.

Specifications, standards and requirements for its intended application.

So, Does Yellow Mean Lower Quality?

NOT NECESSARILY.

Colour alone is not a reliable indicator of glove quality or performance.

What matters is whether the glove meets the relevant specifications, standards and requirements for its intended application.

The Takeaway

A latex glove may look simple. The material behind it is anything but.

From the natural composition of latex to washing, formulation, curing and chlorination, each stage can influence the final shade.

So why are some latex gloves yellower than others?

Because the final colour is shaped by what is naturally present in the rubber, what is removed during processing, and how the glove is formulated and treated.
