METHOD OF MANUFACTURING ENTOMOLOGICAL PREPARATIONS IN SANDARAK BALSAM
A. B. KRASHENINNIKOV

A method for manufacturing permanent preparations in sandarac balsam, a new semi - synthetic medium consisting of sandarac, ethanol, camphor, menthol, chloral hydrate, paraldehyde, and cineol, is presented. To obtain it, a eutectic mixture of camphor and menthol (1:1 by weight)is added to the purified and evaporated sandarak solution in ethanol based on 100 ml of this mixture per 300 ml of alcohol resin solution. Then chloral hydrate is added to the mixture (100 grams of chloral hydrate per 300 ml of sandarak - ethanol - camphor - menthol mixture). To dilute the resulting resin, a solution of paraldehyde in cineol (1:1 by volume) is used. Sandarak balsam is an analog of euparal, but differs from it in the presence of chloral hydrate and menthol, and the absence of phenylsalicylate in its composition.

SANDARAKA BALM

I prefer balms inside.

I prefer balms inside.

Once the accounting department of our charitable institution refused to pay the bill, where the subject of purchase was Canadian balm. Apparently they also preferred balms inside

Comment from the author.

It is better not to use chloral hydrate in the mixture. As time has shown, it recrystallizes. Thus, for the preparation of the drug, it is necessary to bring the object to 95% alcohol, after which it can be transferred to the resin.

The final composition of sandarac balsam: sandarac, cineol, paraldehyde, camphor and menthol. Camphor mixed with menthol are sandarak plasticizers. Without them, it cracks when it dries. Cineol with paraldehyde-solvents for resin. Cineol, by the way, dissolves the Canadian balm well. It is non-toxic. It is the best substitute for xylene, toluene and benzene.

The main question is: where can I buy all these chemicals?

sandarak is sold in art stores.

I bought camphor, menthol, paraldehyde and cineol through Vekton. At the moment, the problem is to get cineol. It's all foreign, not in stock yet. No problem with the rest.

The cost of the mixture is 10 times cheaper than euparal.

Let me remind you again: It is better not to use chloral hydrate
