HYscent refills are made from a proprietary blended polymer infused with pure fragrance oils and pure essential oils. The absence of propellants and harmful solvents make HYscent refills the “eco” conscious solution for your fragrance needs. An innovative odour control. Your customer will smell only pure fragrance oil and NOT propellants and harmful solvents that diminish the character and efficacy of the fragrance. Our fragrances are a malodour counter-actant and essential to our commercial grade air freshener systems.
