Abstract
An insect repellent substrate (10) includes a fabric base material (12) made of felt which is impregnated with a repellent carrier composition (14). The carrier composition (14) includes a mixture of wax and a naturally occurring insect repellent such as pyrethrum oil. The carrier composition (14) may also include scented or aromatic oils such as citronella oil, rosemary oil, eucalyptus oil and neem oil. Strips of the fabric base material may be attached to headwear such as a headband or cap so that it is in contact with the wearer's hair or body. Active constituents of the carrier composition (14) provide effective treatment and prevention of headlice and other parasitic insects.
Claims27
An insect repellent substrate for repelling lice and the like insects and for attachment to a garment, the substrate comprising:
- a strip of fabric base material impregnated with a repellent carrier composition and being adapted to attach to the garment in a manner that will ensure continuous contact of the insect repellent substrate with the wearer's hair or body, the carrier composition including a mixture of wax and an insect repellent whereby, in use, the wearer's body heat causes the carrier composition to soften to provide a controlled release of the insect repellent from the fabric base material.
A method of manufacturing an insect repellent substrate for repelling lice and the like insects for attachment to a garment, the method comprising the steps of:
- producing a repellent carrier composition by:
- heating a wax to a liquid state;
- and,
- mixing an insect repellent with the liquid wax;
- dipping a strip of fabric base material into the carrier composition whilst still in the liquid state for a sufficient length of time to allow the base material to absorb some of the carrier composition;
- allowing the impregnated strip of base material to cool so that the carrier composition solidifies on the base material to form said insect repellent substrate;
- and,
- attaching the substrate to the garment in a manner that will ensure continuous contact of the insect repellent substrate with the wearer's hair or body whereby, in use, the wearer's body heat causes the carrier composition to soften to provide a controlled release of the insect repellent from the fabric base material.
