[Detailed description of the invention]

TECHNICAL FIELD This invention relates to lotion dandruff shampoos containing a dispersed non-volatile silicone phase and pyridinethione salts and stabilized by the use of certain long chain materials. BACKGROUND OF THE INVENTION Dandruff shampoos are well known in the art and rely on a number of different agents for their antidandruff effectiveness. However, washing the hair with anti-dandruff shampoo is done not only to alleviate the dandruff condition but also to clean the hair. Human hair becomes dirty due to contact with the surrounding atmosphere and more often from sebum secreted by the head. Sebum buildup causes the hair to feel dirty and have an unattractive appearance. Dirty hair often requires regular hair washing. Hair washing cleans by removing excess dirt and sebum. However, hair washing methods have the disadvantage of leaving the hair wet, tangled and generally unmanageable. Various approaches have been developed to try to alleviate post-washing problems. These range from incorporating hair conditioning aids into shampoos to applying hair conditioners, ie hair rinses, after washing the hair. Hair rinses typically work by depositing a polymer film or other material onto the hair. However, such solutions to very prevalent problems have not been fully satisfactory. First of all, the hair rinse must be applied in a separate step after hair washing, left on the hair for a certain time and rinsed with fresh water. This, of course, is time consuming and not convenient. Shampoos containing conditioning aids (both dandruff shampoos and regular shampoos) have been disclosed, but are not always satisfactory for various reasons. One problem relates to compatibility issues between good cleaning anionic surfactants and fatty cationic agents that are good conditioning agents. This has led researchers in the field to investigate other surfactants, such as nonionic surfactants, amphoteric surfactants, and zwitterionic surfactants. Many of these efforts are reflected in patents issued in the area of conditioning shampoos. For example, U.S. Pat.
See US Pat. No. 3,849,348, US Pat. No. 3,990,991 and US Pat. No. 3,822,312. The use of these other surfactants solved many of the compatibility problems, but still did not provide a complete answer in all areas. For example, cationic conditioners may not provide the desired level of flexibility desired by the user. Materials that can provide increased flexibility are silicones, both soluble and insoluble in the shampoo matrix. Silicones in shampoo compositions are disclosed in a number of different publications. Such publications include US Pat. No. 2,826,551, US Pat. No. 3,964,500, US Pat. No. 4,364,837 and British Patent No. 849,433. Although these patents disclose silicone-containing compositions, they also do not provide answers to all of the problems encountered in preparing completely satisfactory products. One problem is that of keeping the dispersion-insoluble silicone material suspended and keeping the overall product stable. One approach to attempting to stabilize silicone-containing shampoos has been to use certain long chain derivatives and other long chain derivatives. Such an approach is found in European Patent Application No. 0181773. This same approach has been used to suspend anti-dandruff agents such as zinc pyridinethione. An exemplary patent demonstrating this approach is US Pat. No. 4,470,892. The inventors have surprisingly found that when silicone and pyridinethione salts are used together in a system as described above, the substances can be suspended without increasing the amount of suspending agent and provide good hair conditioning. It has been found that improved deposition of pyridine thione salts can be provided. It is therefore an object of the present invention to provide a stable silicone-containing conditioning lotion shampoo that also has excellent anti-dandruff activity. Yet another object of the present invention is to provide a silicone shampoo composition with improved wet combing benefits. These and other objects will become readily apparent from the specific description below. Unless otherwise specified, all percentages and ratios herein are by weight. SUMMARY OF THE INVENTION The present invention comprises about 5% to about 70% synthetic surfactants, about 0.01% to about 10.0% insoluble non-volatile silicones, about 0.5% to about 5.0% certain long chain derivatives, about 0.8% pyridinethione salts.

[Formula] Metal salt represents the replacement of one hydrogen in a tautomeric form by a metal. Of course, there can be more than one pyridinethione ring in the compound depending on the valence of the metal involved. Suitable heavy metals include zinc, tin, cadmium and zirconium. Preferred pyridinethione salt crystals for use in the present invention primarily have an average sphericity of less than about 0.65, preferably from about 0.20 to about 0.65, and a median particle size of at least about 2 microns in diameter, expressed as the median equivalent diameter of spheres of equal volume.

Analysis), Ann Arbor Science, 1978. The sphericity of the particles is also calculated by Stockham and Hochtman on page 113 using the following formula: Z = (d _o /d _s ) ² (where d _o is the diameter of the sphere with the above-mentioned equivalent capacity, and d _s
is the diameter of a sphere of equivalent area). In the present invention: Average sphericity = (d/- _o /d _s ) ² or surface area of a sphere with equivalent volume distribution/actual surface area of the particle as measured.

It is then pumped through a heat exchanger to approximately 27°C.
Mix the mixture thoroughly for approximately 10 minutes at 72 °C before cooling to . Then add the pyridinethione salt at 27°C and mix thoroughly. A high shear mill is used to achieve proper dispersion of the silicone fluid. This means that the average particle size is approximately 10μ
This is achieved by having: In the cooling step, the acyl derivative is preferably crystallized into particles having an average particle size of about 10 microns or less. In another method, the surfactant portion is not added until the product has cooled. This can help control the crystallization of the acyl derivative.
