such as surfactants lubricants texture modifiers acidifiers and or preservatives useful optional surfactants include without limitation sodium lauryl sulfate sorbitan laurate mixtures of glyceryl stearate and peg 100 stearate methyl gluceth 10 methyl gluceth 40 sorbitan palmitate polysorbate 20 polysorbate 80 steareth 2 and many others the surfactants will be present in amounts about 0 1 to about 16 percent and can create shampoo type products which are easily removed after the ectoparasite treatment is completed the lubricants that can be incorporated are represented by dimethicone simethicone and other silicone type materials and act to lubricate and condition the hair as well as facilitate passage of a comb through the hair useful concentrations when this component is present are about 0 1 to about 2 percent optional texture modifiers that may be included are exemplified by stearic acid cetyl alcohol peg 180 polyethylene glycol 1450 and polyethylene glycol 3350 in amounts about 0 1 percent to about 5 percent it may be desired to incorporate a ph adjusting ingredient in the composition if the hydrated active ingredient tends to establish excessively acidic or alkaline conditions such as ph values which are less than about 4 or greater than about 9 optional acidifiers that may be used include without limitation benzoic acid citric acid and stearic acid useful optional alkalizers include without limitation calcium hydroxide magnesium hydroxide and organic bases such as triethanolamine the ph adjusters when used will generally be present in amounts about 0 1 percent to about 2 percent as needed to obtain a desired bulk ph condition as an alternative to incorporating a ph adjusting ingredient suitable bulk ph conditions can frequently be obtained by incorporating an active ingredient that yields acidic conditions together with another active ingredient.
