Tanchico: Coconut-oil Wax

tested for glycerin. The bisulphite test gave no acrolein odor
and the silver-mirror test was also negative. These experiments
show that the purified coconut-oil residue does not yield glycerin
as a decomposition product and is, therefore, not a glyceride.
This residue would appear to be a wax containing the myricyl
ester of cerotic acid.
COMMERCIAL PRODUCTS
The basic material used for these preparations was the crude
coconut-oil residue. This was filtered to remove most of the
coconut oil. It was then melted and again filtered to eliminate
dust and other impurities.
Floor wax.-The ingredients for this product were mixed in
accordance with the following proportions:
Constituent. Per cent.
Coconut-oil wax 32
Carnauba wax 15
Hercules rosin 3
Tallow 21
Turpentine 29
Total 100
The solid materials were melted together over a small flame.
The flame was then extinguished and the turpentine and
some coloring matter were added. The mixture was stirred
thoroughly and poured into a container, which was stoppered
tightly to prevent loss of solvent. The container was immersed
immediately in ice water in order to solidify the mixture quickly
as otherwise the ingredients tend to separate in layers.
The coloring matter was made by extracting a quantity of
annatto seeds (Bixa orellana L.) with turpentine. The amount
of dye solution to be added depends upon the color desired.
The consistency of the floor wax may be varied by combining
the constituents in somewhat different quantities.
Furniture polish.-The materials were mixed in the proportions given below:
Constituent. Per cent.
Stearic acid 7
Triethanolamine 2
Carnauba wax 21
Coconut-oil wax 11
Turpentine 26
Water 33
