Abstract
A fragrance delivery system which includes a container with reservoir compartment and having an outer wall at least partially formed of a fragrance permeable plastic, the plastic being a thermoplastic elastomer block copolymer having a Volume Resistivity from 1×1012 to 1×1020 Ohms·cm and a Water Absorption from 4 to 20%; and a fragrance composition held within the reservoir, the composition being a mixture of low and high volatile perfume ingredients.
Claims15
A fragrance delivery system comprising:
- a) a container with at least one reservoir compartment, the container having an outer wall at least partially being formed of a fragrance permeable plastic;
- i) the plastic being a thermoplastic elastomer block copolymer;
- ii) the plastic having a Volume Resistivity ranging from 1×1012 to 1×1020 Ohms·cm;
- and
- iii) the plastic having a Water Absorption ranging from 4 to 20%;
- and
- b) a fragrance composition held within the at least one reservoir compartment, the composition being a mixture of:
- (1) high volatile perfume ingredients having a boiling point lower than 250° C.;
- and (2) low volatile perfume ingredients having a boiling point higher than 250° C.;
- and wherein the system simultaneously transmits both the high and low volatile perfume ingredients at a uniform and steady rate to space outside the system.
A method for simultaneously transmitting both high volatile perfume ingredients and low volatile perfume ingredients at a uniform and steady rate to space outside a plastic container, the method comprising:
- selecting a container with at least one reservoir compartment, the container comprising an outer wall at least partially being formed of a fragrance permeable plastic;
- i) the plastic being a thermoplastic elastomer block copolymer;
- ii) the plastic having a Volume Resistivity ranging from 1×1012 to 1×1020 Ohms·cm;
- and
- iii) the plastic having a Water Absorption ranging from 4 to 20%;
- and
- placing a fragrance composition within the at least one reservoir compartment, the composition being a mixture of:
- (1) high volatile perfume ingredients having a boiling point lower than 250° C.;
- and (2) low volatile perfume ingredients having a boiling point higher than 250° C.
