Abstract

A louse repellent composition is provided which comprises a solution of piperonal in an amount of at least 1% by weight in an aqueous alcohol, the solution containing a non-ionic emulsifier comprising an alkoxylated alcohol or fatty acid, and being capable of forming a film on the skin without rapid formation of crystals of piperonal.

Description

LOUSE REPELLENT COMPOSITIONS The present invention relates to louse repellent compositions In our co-pending application No. 9004020.5 we disclose a composition which is effective in killing lice and eggs and acting as a louse repellent. Although the compositions of our above application have proved to be effective, they do suffer from some disadvantages. One of these is that the compositions contain high levels of alcohol in order to maintain the solubility of the piperonal and to avoid premature crystallisation when spreading the composition on the hair. High concentrations of alcohol in the compositions can cause skin irritation which is an undesirable side effect.
According to the present invention, therefore, there is provided a louse repellent composition which comprises a solution of piperonal in an aqueous alcohol, said solution containing a non-ionic emulsifier comprising ari alkoxylated fatty alcohol or fatty acid, the compositlon being capable of forming a film on the skin without rapid formation of crystals of piperonal. The presence of the non-ionic emulsifier enables the alcohol content of the compositions to be reduced.
The alcohol composition, preferably, is a mixture of ethanol and propanol, especially isopropanol. In addition to reducing the alcohol content, the compositions of the invention have high stability against crystallisation at low temperature, e.g. down to OOC which reduces the danger of crystals forming and blocking the dispenser. The compositions also have better appearance when applied to the hair and skin.
Preferably, two emulsifiers are employed in the compositions of the invention. These are an hydroxy fatty alcohol alkoxylate and an alkoxylated castor oil fatty acid. These two emulsifiers appear to act synergistically in keeping the piperonal in solution and deterring crystallisation.
Because of the higher water content in the compositions of the invention, they are more pleasant to use and crystallisation is delayed. The piperonal may be employed in relatively low compositions and still be effective as a repellent for lice.
h further advantage of the compositions of the invention is that piperonal gives the compositions a pleasant fruity flavour. Concentrations of piperonal from about 0.5 to 10% may be employed, preferably 1 to 3%.
The compositions may also preferably include phenoxyethanol as anti-microbial preservative.
One example of the present invention will now be described by way of illustration.

The two emulsifiers were dissolved in the water, together with phenoxyethanol and piperonal dissolved in the ethanol. isopropyl alcohol was added to the ethanol with was then added to the water solution to form a clear solution. The resulting solution can be packaged in an aerosol or pump-type dispenser.
