Definitions
- This invention relates to antimicrobial hair treatment compositions for topical application to human hair and scalp for the treatment of, for example, dandruff.
- the invention relates to a hair treatment composition comprising a surfactant, water- insoluble antimicrobial particles and a cationic polymer which serves to enhance the deposition and retention of the particles on the hair and/or the scalp from the composition.
- Insoluble particulate metal pyrithiones are acknowledged as antimicrobial agents which can be incorporated into antimicrobial compositions, such as antidandruff hair shampoos and conditioners.
- the zinc salt hereinafter referred to as ZnPTO
- ZnPTO zinc salt
- dispersed particles of the ZnPTO are suspended in the composition, which is then applied to the hair to deposit the ZnPTO on the hair and scalp.
- a problem encountered with such compositions is that it is difficult to obtain a stable dispersion containing ZnPTO, since its specific gravity and insolubility leads to precipitation and separation during storage. Steps taken to prevent precipitation and separation of the ZnPTO particles have hitherto included restriction of the formulational base to highly viscous emulsions or gels, e.g., by incorporation of thickeners or bulking agents to give structural viscosity to the system and prevent ZnPTO settlement . Such an approach is frequently impractical for shampoo compositions and can give cloudy, aesthetically- inferior products.
- the anti -dandruff benefits attainable from particles of ZNPTO incorporated in hair treatment compositions are frequently limited, owing to a poor level of deposition on the intended site; namely the hair and/or the scalp, but particularly the scalp.
- a further problem encountered with such compositions is that acceptable aesthetic properties, such as pearlescence, of the compositions are often difficult to achieve.
- the general approach taken to improve the pearlescence is to incorporate pearlescent materials such as ethylene glycol distrearate in the compositions.
- pearlescent materials such as ethylene glycol distrearate
- Such an approach alone is frequently dissatisfactory owing to the presence of metal pyrithione particles interfering with the ability of the pearlescent materials to deliver acceptable pearlescence.
- ZnPTO crystals having a flat plate-like morphology interfere less with pearlescers in such compositions.
- EP 34385 describes an aesthetically improved anti-dandruff hair care composition comprising flat, platelet shaped ZnPTO crystals.
- JP 8283242A describes a "mica like" shaped l-hydroxy-2- pyridinethione heavy metal salt for use in hair care compositions. The mica shaped crystals are said not to impede pearlescence.
- antimicrobial hair treatment compositions which have good mechanical stability, good optical properties and excellent anti-dandruff ability can be obtained by utilising needle-shaped particles of insoluble particulate metal pyrithione in combination with a deposition aid.
- an antimicrobial hair treatment composition comprising:
- the invention also provides a method of treating dandruff comprising applying to the hair a composition according to the first aspect of the present invention.
- an antimicrobial hair treatment composition of particles of an insoluble particulate metal pyrithione in which at least 50% by number of the particles are needle shaped particles having a length of between 1 and 50 microns.

- M is a polyvalent metal ion and n corresponds to the valency of M.
- M include magnesium, barium, strontium, zinc, cadmium, tin and zirconium. Especially preferred is zinc.
- needle-shaped particle used herein is used to describe a generally elongate three dimensional particle of any transverse cross-sectional shape, the particle having one dimension, the length, substantially greater than the other two. By “substantially” is meant greater by a factor of at least two, preferably at least 3 and most preferably at least 5. Although the cross-sectional shape of the particle is not particularly critical it is typically polygonal .
- the needle-shaped particles of metal pyrithione have a size distribution in which at least about 50% of the particles, by number of the particles, have a length of between 1 and 50 microns.
- the size distribution is such that at least about 50% of the particles, by number of the particles, have a length of between 2 and 40 microns; most preferably between 4 and 30 microns and even more preferably between 5 and 15 microns; the most preferred length being between 10 and 15 microns.
- the size distribution is such that at least about 70% of the particles, by number of the particles, have a length of between 2 and 40 microns; most preferably between 4 and 30 microns and even more preferably between 5 and 15 microns; the most preferred length is between 10 and 15 microns.
- the size distribution is such that at least about 80% of the particles, by number of the particles, have a length of between 2 and 40 microns; most preferably between 4 and 30 microns and even more preferably between 5 and 15 microns; the most preferred length being between 10 and 15 microns.

- the amount of polyvalent metal salt is used in a slight (such as 5%) stoichiometric excess, relative to the amount of water-soluble pyrithione salt employed.
- the temperature of the reaction mixture should be maintained at between 20 and 60 degree Celsius, and stirring of the reaction mixture continued until all of the polyvalent metal salt solution has been added and a precipitate forms.
- the resulting rods and needles of insoluble zinc pyrithione salt are collected by vacuum filtration and washed in cold water.

- a sample of ZnPTO particles prepared as described hereinbefore was shaken thoroughly and 10 microlitres was removed by pipette and diluted with 18 mililitres of water. A small amount of the diluted sample was placed onto an aluminium stub and left to air dry for two hours afterwhich the stub plus diluted sample was placed under vacuum for 48 hours. The samples were then coated with gold Ca 5nm to aid conductivity before imaging at lOkv. Ten photographic images of the sample were taken. Total number (T) of whole needles in each photograph were counted and measured. Those particles having a length of between 1 and 50 microns, which dimension was substantially greater than its other two, represented "needle-shaped particles" (N) as defined hereinbefore. The percentage by number of the particles in the sample that were needle-shaped particles having a length of between 1 and 50 microns was accordingly determined by the calculation (N/T)X 100.
- test shampoos were made from a common base, namely 14 % sodium lauryl ether sulphate (2EO) , 2% cocamidopropylbetaine, 0.1 % JAGUAR C13S (guar hydroxypropyltrimonium chloride, ex Rhodia) , 6% pearlising agent Mirasheen CP 820, ex Rhodia and suspending, colouring and preserving agents.
- the following ZNPTO particles were additionally added to the test shampoos A to E.
- Shampoos B and E contain ZnPTO particles in which at least 50% by number thereof are ZnPTO needles according to the present invention.
- Shampoos A, C,and D contain standard size ZnPTO particles ex Olin and thus serve as comparative examples outside the present invention.
- composition B containing needle-shaped ZnPTO is better than composition A, identical to B except for containing prior art ZnPTO particles.
- composition E containing needle-shaped ZnPTO particles is better than compositions C and D, identical to E except for containing prior art ZnPTO particles.
- Hair shampoo compositions in accordance with the present invention comprising needle-shaped particulate metal pyrithione and a deposition polymer were prepared using techniques well known in the art.
- the ZnPTO particles were prepared as described herein.
