All of our Franken / Solvent Resistant Glitters have passed the MEK TEST.
What is MEK?
Methyl ethyl ketone (MEK) is a strong colorless liquid solvent that has a sharp, sweet odor. Methyl ethyl ketone (also known as 2-butanone) is a man-made chemical that is also found in nature. It is related to acetone and is used in dissolving paint, lacquer, varnishes and cleaning agent.
How Does Glitter Pass the MEK Test?
Glitter is soaked in MEK for 5 minutes. If the glitter does not bleed color or melt/dissolve any, this glitter would be considered solvent resistant.
Franken Glitter Materials
- Polyester Glitter - Tiny colored metallic pieces perfectly cut to give maximum sparkle, and shine. It is made with high quality material, and can be placed directly into nail polish. These glitter powders are solid, brilliant in color and have a very smooth texture.
- Polyester Jewel - Cut with exactness, tiny holographic pieces made with high quality materials giving a rainbow reflective sparkle and shine. Polyester Jewel Glitter can be placed directly into nail polish.
Why Aren’t the Acrylic Polyester Glitters Solvent Resistant?
Acrylic Polyester Glitter is tiny perfectly cut colored plastic pieces, coated with an outside layer of polyester material. The outside layer of these glitters is solvent resistant, but because the glitter is layered, the MEK or solvent is able to seep into the side of the glitter and dissolve the color and plastic core. Just as though acetone dissolves acrylic nails.
