Product Information

About the Product

Double Duty Precision Liquid Eye Liner is a water resistant liquid eyeliner supplied in a 2.7 mL size in the shade Black. The colour comes from a single pigment, black iron oxide, and the water based formula sets with acrylate copolymers. It is vegan and is formulated without parabens, carbon black or coal tar dyes.

Liquid eyeliner is worn to draw a defined line along the outer lash line, and this one is applied from the inner to the outer corner of the eye and left about 30 seconds to dry before the eye is opened fully. It is ophthalmologist developed and tested.

Key Ingredients

  • Acrylates/Octylacrylamide Copolymer and Acrylates Copolymer The film forming polymers that dry down and give the liner its water resistant wear.
  • Iron Oxides (CI 77499) The single pigment in the formula, a black iron oxide used in place of carbon black or coal tar dyes.
  • Ceramide NP, Cholesterol and Hydrogenated Lecithin Lipids carried in the formula alongside the film formers.
  • Argania Spinosa Kernel Oil and Ricinus Communis (Castor) Seed Oil Argan and castor oils, the two plant oils in the base.
  • Sodium Hyaluronate and Glycerin Humectants that hold water in the formula.
