PBT fiber, synthetic protein, these may be the materials used to make your vegan eyelashes. Different vegan lashes use different materials, and there are huge differences in the quality of eyelashes made of PBT fibers at different costs. Different materials have different effects on eyelashes.
Vegan Lashes Made of PBT Fiber
Faux mink lashes and silk lashes are made of a plastic fiber called PBT, polybutylene terephthalate. PBT is a thermoplastic semi-crystalline polymer. It is a polyester that is shaped into the desired eyelash shape after heating, and will solidify after cooling. It is a high-performance material with a high molecular weight and is known for its strong, flexible and durable plastic.
PBT creates natural looking lashes with a gorgeous soft and glossy sheen which doesn’t lose its curl. Not only this, but PBT causes the least chance of an allergic reaction on human skin compared with all other eyelash extension materials.
While you might not have heard of PBT lashes, you will probably have come across silk or faux mink lashes, which are names the manufacturers have come up with to make PBT sound more appealing.
Vegan Lashes Made of Synthetic Protein
Synthetic protein is a degradable covalent cross-linked polymer, which is currently the latest technology applied to eyelashes. The vegan eyelashes made of synthetic protein are heat-resistant, waterproof, soft and strong. And it is biodegradable and very environmentally friendly.
