The present invention is based on the observation that those in water work as well like insoluble heptyl and octyl alcohols have a strong antiseptic effect when they are in appropriately "unlocks", e.g. B. treated with soap or soap solutions, with similar brings active vehicles into an applicable form or in lower alcohols or in other suitable solvents

ίο dissolves.

As has been found, you can use these alcohols both on their own and in Solution, e.g. B. in alcoholic solution, to strengthen the effect of the lower alcohols, also in oily solution as well as in connection with soap solutions or solid soap (as solid alcohol preparations) or with acids, alkalis and the like.

It is already known that the higher water-soluble alcohols are germicidal Possess properties. From this, however, the conclusion could not be drawn without further ado that also such alcohols as the heptyl and octyl alcohols, which are insoluble in water,

-25 have a greater germicidal effect than the water-soluble, especially since the work von Koch have shown that disinfectants that are not water-soluble are not exert germicidal effect, and that even oily solutions of in aqueous solution are effective. Disinfectants have good disinfecting properties due to their oily character lose.

Investigations have now shown that, surprisingly, heptyl and octyl alcohols, especially those which contain the hydroxyl group on the first or second carbon atom, in spite of their oily Character and their water solubility have excellent antiseptic properties. For example, the preparations prepared according to the following examples resulted in the the results given in the following tables.

Example I.

16 parts of the castor oil by heating according to the patent specification 104499 obtained product were with 5.8 parts of potassium hydroxide solution of 50 ° Be. and 30 parts Water saponified by boiling and the soap adjusted to 50 parts by evaporation.

This soap solution was then mixed with 50 parts of primary heptyl alcohol of the formula

CH ₃ - (CH ₂ ) ^ CH ₂ OH

mixed.

Example II.

50 parts of the same soap, the preparation of which is described in Example I, were with 50 parts of secondary octyl alcohol of the formula

CH ₃ . (CH ₂ ) ₅ . CHOH CH ₃

mixed.

The preparations produced according to these two examples were in ι percent and 3 percent solution tested for its effect on various bacteria. That The behavior results from the following tables:
