An NBR foundation sponge is a makeup sponge made from Nitrile Butadiene Rubber, a material designed to:

• Be non-latex (safe for sensitive & latex-allergic skin)

• Have a smooth, firm texture

• Absorb very little product

• Give precise, streak-free application

• Work well with liquid, cream, and stick foundations

  Why NBR is Popular for Makeup Sponges

  NBR sponges:

  • Don’t soak up too much foundation → less product waste

  • Provide more control for blending

  • Are durable and long-lasting

  • Are often used in professional makeup kits

  They are different from:

  • PU sponges (softer and more absorbent)

  • Hydrophilic sponges (expand when wet, used for beauty blenders)

  NBR sponges do not expand in water and are usually used dry.
