The Complete Guide to Latex Gloves

Latex gloves have been a cornerstone of personal protective equipment (PPE) across various industries for decades. Their unique combination of elasticity, sensitivity, and barrier protection makes them indispensable in medical settings, food service, beauty industries, and beyond. This comprehensive guide explores everything you need to know about latex gloves, from their composition and types to applications and selection criteria.

What Are Latex Gloves?

Latex gloves are made from natural rubber latex, a milky fluid derived from the rubber tree (Hevea brasiliensis). This natural material undergoes processing to create a thin, elastic, and durable barrier that conforms perfectly to the hand’s contours. The manufacturing process typically involves dipping hand-shaped molds into liquid latex, followed by washing, drying, and quality testing.

Types of Latex Gloves

Powdered Latex Gloves

Traditionally, latex gloves were coated with cornstarch powder to make them easier to don and doff. The powder reduces friction and absorbs moisture, allowing for smooth application even with damp hands. However, powdered gloves have fallen out of favor in many settings due to health concerns.

Powder-Free Latex Gloves

These gloves undergo additional processing to remove powder. They typically feature a chlorinated or polymer coating that facilitates donning without powder. Powder-free gloves are now standard in most medical and food service environments due to reduced risk of allergic reactions and contamination.

Sterile Latex Gloves

Used primarily in surgical and specific medical procedures, sterile latex gloves undergo additional processing to eliminate microorganisms. They are individually packaged and often feature a longer cuff for enhanced protection.
