Material Classification of Beauty Blenders & Cushion Puffs
NR (Natural Rubber):
This is the cheapest option but tends to age and crumble quickly.
Natural latex can also easily cause skin allergies, which may lead to misunderstandings-many people think they're allergic to foundation, when in fact, the problem could lie with the makeup tool. This material is usually used for disposable sponges.
SBR (Styrene-Butadiene Rubber):
Sl
ightly more expensive than NR natural rubber.
Its advantage is good water absorption, which helps dilute the foundation and create a lightweight makeup look.
It doesn't crumble as quickly either. However, the material is relatively hard, with large pores that absorb more product. Affordable self-service stores often use this material to make beauty sponges-for example, a well-known brand's sponge.
NBR (Nitrile Butadiene Rubber):
Higher cost. It absorbs less water and makeup. The material is dense and suitable for both wet and dry use, with oil resistance.
This material is commonly used to make affordable powder puffs.
Hydrophilic Polyurethane (Non-Latex):
This is currently the preferred material for many beauty blenders on the market.
It features a combination of large and small pores and expands when wet.
It feels soft, has good water absorption, and is oil-resistant.
It's resistant to aging and doesn't crumble easily. Differences in density and formula can affect its ability to absorb and release product.
Neopora & Rubycell:
These two materials are usually used for the outer layer of cushion puffs.
Compared to regular sponges, they offer better stretchability, tear resistance, and mold resistance.
Polyester Sponge:
Typically used in the inner layer of cushion puffs, paired with Neopora or Rubycell.
It has excellent oil absorption, good resilience, and is resistant to acids and alkalis.
Many ink pad sponges are also made from this material.
