Formula

• According to the Fashion Magazine website, the first waterproof mascara formulated in 1938 contained a blend of 50-percent turpentine. Unsurprisingly, the mascara had a nasty smell and caused skin allergies.
  
  

Improvements

• Until the 1950s, mascaras had a petroleum base. Synthetic formulas replaced them in the 1950s and 1960, which led to the development of more eye-friendly waterproof mascaras. A safe, waterproof tube-dispensed mascara became available in the early 1960s. Women could apply the mascara without eye irritation, enabling them to imitate the model Twiggy's uber lashes.
  
  

Function

• Waterproof mascara gave woman the freedom to cry or walk in the rain without smudging their mascara and losing their lovely long eyelashes.
