.
BACKGROUND OF TE~E INVENTION
There are only a relatively few ectoparasiticides which are commercially available today. The most popular pediculicidal toxicants are Lindane tgamma benzene hexa-chloride), Malathion [(S-1,2-dicarbethoxyethyl)-0,0-dimethyl phosphorodithioate], synergized pyrethrins and Cuprex (a combination of tetrahydronapthalene, copper oleate and acetone, the acetone not asserted to be active). Sulfur, LINDANE, benzyl and crotamiton are the best known agents for scabies. Because of increased concern about the overall safety of somé of the Xnown ectoparasitic toxicants, the search for new, safe and ef~ective ectoparasiticides has intensified recently.
It has now been found that certain polyols are effective ovicides, miticides and, depending on formulation are also pediculicidal. The polyols are well known compounds but the insecticidal and/or ovicidal activity thereof has not been previously known. 2-ethyl-1,3-hexanediol is well known as an insect repellent (cf. U.S. 2,407,205 and 3,836,672) and is in wide commercial use as such.
It is the object of this invention to provide new, safe and effective toxicants for insects and their ova. This and other objects of the invention will become apparent to those skilled in the art from the following detailed description.

109~9 SU~ RY OF T~IE INVENlION
This in~ention relates to ectoparasiticidal toxicants and a method of controlling ectoparasites, other biting insects and mites. More particularly, the invention relates to the use of certain polyols as to~lcants for lice, mites, and/or their ova and to toxicant compositions con-taining such polyols.
DESCRIPTION OF ~HE PREFERR~D E~lBODIMENTS
_ _ .
Certain polyols which are diols whose hydroxyl groups are in non-vicinal positions, preferably 1,3-diols, have been found to exhibit satisfactory activity. Exemplary polyols are
2-methyl-2,4-pentanediol, 2-ethyl-1,3-hexanediol, 1,3-butan~diol, 1,3-heptanediol and 1l3-nonanediol. One or a combination o* the toxic polyols of the present invention can be incorporated into an active toxicant composition which can be in the form of a liquid, powder, lotion, cream, gel or aerosol spray, or foam as the result of formulation with inert pharmaceutically acceptable carriers by procedures well known in the art. Any pharmaceutically acceptable carrier, whether aqueous or not aqueous, which is inert to the active ingredient can be employed. By inert is meant that the carrier does not have a substantlal detrimental effect on the insecticidal, miticidal or ovicidal toxicant ac*ivity of the active ingredient.
The active polyol is incorporated into the toxicant composition used to treat the substrate (human, animal or inanimate) in need of such treatme~t, belie~ed *o be in need of such treatment, or desired to be prophylactically protected in an effective toxicant amount. By such amount is meant the amount which will cause at least 50% mortality of the ecto-parasites or their ova. Wi*h respect to lice and their ova, 2.
the standard two minute in-mersion tests are described below.
The minimum concentration of polyol in the composition required to provide an efective toxic amount varies con-siderably depending on the particular polyol, the particular inert pharmaceutically acceptable carrier being employed and any other ingredients ~hich are present. Thus, in one case a 10~ concentration may sufice, while in other cases, con-centrations as high as 30 to 40~ may be required to obtain a~
effective toxic dose.
The two minute immersion tests referred to above are carried out as follows:
Pediculicidal activity: A 50 ml beaker is filled with tap water and allowsd to come to room temperature (about 24C~. Ten young adul* male and ten young adult female lice (Pediculus humanus corporis) of the same age group and from the same stock colony are placed on a 2x2 cm coarse mesh patch. The sample to be tested, maintained at roo~ temperature~
is shaken until homogeneous and placed into a 50 ml beaker.
The mesh patch is placed into the sample immediately after pouring, allowed to submerge, and after two minutes is removed and immediately plunged into the beaker containing the tap water. The patch is vigorously agitated every ten seconds and af*er one minute the patch is removed and p~aced on paper toweling. The lice are then transferred to a 4x4 cm blac~
corduroy cloth patch and this point of time is considered zero hours. Thereafter, the corduroy patch is placed in a petri dish which is covered and stored in a 30Q holding chamber for 24 hours.
Ovicidal activity: 15 adult, 5 to 10 day old, female lice (Pediculus humanus corporis) are placed on a . . _ _ . . . ~
2x2 cm nylon mesh patch which is placed in a petri dish, covered and maintained ill an incubator at 3DC for 24 hours.
The adult lice are then removed and the number of plump, viable eggs and shriveled non-fertile eggs on the patch are recorded. The sample to be tested, maintained at room temperature, is shaken until homogeneous and poured into a - 50 ml beaker. Immediately after the pou~ing, the mesh patch is placed into the beaker, allowed to submerge, and a~ter two minutes is remo~ed and immediately plunged into a 5~ ml ~eaker containing tap water at room temperature ~about 24C~. The patch is vigorously agîtated every ten seconds and after ~ne minute, the patch is removed and placed on paper toweling for one minute. The patçh is then placed in a petri dish which is covered and stored in the 30C incubator. Fourteen days following treatmen~, a number of hatched eggs and the number - o shriveled or unhatched eggs is noted.
In both the pediculicidal and ovicidal two minute immersion tests, controls are run in identical manners to that described with room tempelature ~24C) tap water substituted for the sample to be tested. The results of the tests repor~ed are net results.
It will be appreciated that the polyols of this invention can be utilized as adjunct toxicants in compositions which are otherwise insecticidal and/or ovicidal. In such compositions, the term "effective toxic amount" means the amount which will cause at least 20~ increase in the mortality of the ectoparasites exposed in the two minute ;mmersion test relative to the same composition without the polyol.

The hexanediol is also an excellent pediculicidal toxicant. It was further surprisingly found that the pentanediol, while not pediculicidal in un-diluted form, imparted pediculicidal acti~ity to compositionswhich would not otherwise exhibit such activity~ e.g., aqueous aliphatic alcohol solutions and a~ueous aliphatic ester solutions. This fact is shown in the data pr`esented b010w.
Additionally~ it has been observed that the instant polyols are effective toxicants towards the rabbit ear mite, the m vitro surrogate for testing toxicants for the sarcopic mite.
Accordingly, the diols can be used to prepa~e compositions which are both ovicidal and scabicidal and, in the case of the hexanediol, also pediculicidal.
