Latex gloves, made of natural rubber which offers high comfort, flexibility, and tactile sensitivity, are a common type of disposable gloves used for various purposes like medical, dental, food service, and industrial applications. However, latex gloves are also prone to discoloration over time, when they come in contact with certain substances or environmental factors, especially. In this guide, the phenomenon why latex gloves turn brown and how to prevent or reduce it will be explained.
One of the main reasons is oxidation, which is a chemical reaction occurring when latex gets exposed to oxygen, heat, light, or other oxidizing agents. The double bonds in the natural rubber molecules break down to form new compounds like ketones, aldehydes, and carboxylic acids, which have different colors ranging from yellow to brown to black than the original latex, due to oxidation. Oxidation also reduces the elasticity and strength of latex, making it more brittle and prone to tearing.
Another reason is the interaction with the natural oils and sweat on our hands when we wear latex gloves. A thin layer of dirt is created on the gloves’ surface by the oils and sweat from skin mixing with the latex. This dirt can also react with oxygen and other substances like chemicals, metals, bacteria, and cause discoloration. The dirt can also accumulate in the creases and folds of the gloves, making them look darker and more stained.
There are some ways to prevent or reduce the discoloration of latex gloves:
Store latex gloves in a cool, dry, and dark place to avoid exposing them to direct sunlight, heat, humidity as these factors can accelerate oxidation and degradation of latex.
Use powder-free latex gloves because powdered latex gloves contain cornstarch, absorbing moisture and promoting bacterial growth, which can produce acids and enzymes damaging and discoloring latex. Powder-free latex gloves are also less likely to cause allergic reactions and skin irritation.
Wash your hands before wearing latex gloves to remove dirt, oils, sweat from skin, which can reduce contamination and discoloration on the gloves. Use mild soap, water and dry hands thoroughly before putting on the gloves.
Change latex gloves frequently to prevent buildup of dirt, bacteria, chemicals on gloves causing discoloration and degradation. Dispose of used latex gloves properly and do not reuse them.
Use colored latex gloves to mask discoloration caused by oxidation, dirt and make the gloves look more appealing, professional. Colored latex gloves can also be used for different purposes.

File Size: 104.31 KB
Natural Degradation of Latex Over Time and Its Impact on Color
Latex, a marvel of nature and chemistry, is not immune to the relentless march of time. In its journey from resilience to fragility, latex undergoes a gradual process known as crosslink degradation. Here, the critical sulfur bonds that interlace the latex polymer matrix start to deteriorate, stripping away the material’s inherent strength, elasticity, and barrier properties. This inevitable decline in molecular integrity is visually marked by a shift in color – typically to shades of brown or yellow. These color changes are not merely cosmetic but symptomatic of the deeper chemical transformation occurring within. The severity of this discoloration is directly tied to the extent of degradation, influenced by environmental exposures such as heat, light, and oxygen.
