The author concluded from his study that:
1. The addition of small quantities of typical surface active substances
to generally used stabilizers for emulsions not only does not result in the
breakdown of 'the emulsions but, on the contrary, increases their dispersion
and stability.
2. The dispersion of the emulsions thus formed depends on the nature of
the surface active material added as well as its relative amount.
3. The addition of surface active substances contributes to the gelation
of water-oil emulsions formed from cottonseed oil and a concentrated caustic
aldali solution.
it. Multistage emulsions are formed in the presence of benzaldehyde and,
especially, formaldehyde.
Miscrophotographs were. made of a water-oil emulsion not containing surface
active agents of this eiAulsion if the presence of 0.12 percent and 0.6 percent
ethyl alcohol; in the presence of 0.13 percent and 0.6 percent isoan>yrl alcohol;
in the presence of 0.2 percent phenol; in the presence of 0.26 percent naphthol;
in the presence of 0.5 percent benzaldehyde; and in the presence of 0.1 percent
formaldehyde.
These shoved that the larger quantities of the alcohols in each case in-
crease the degr a of dispersion but tend to produce deemulsification. The ra-
pidity of dispersion is increased with naphthol. Because the dispersion was
comparatively rapid in all cases, the photographs were taken no more than 5
minutes after the emulsion was formed.
