Help with Fish-oil based ‘Gel’
I have been working on a personal project for a little while
now to create (or replicate) some of the commercial fishing scent attractants
. I am working off of the idea that they are based on a fish oil which will
slowly disperse in the water. I have little to no real experience in the
chemistry field but I am having fun experimenting and trying to learn. I
understand this may not be in line with the main purpose of this site (as its
not cosmetics related) but I am hoping that the chemistry experience of the
folks here would be transferable to this project.
I have been using a base of Tuna Oil (like this)
and trying to build from there. I have tried various combinations of Tuna Oil,
80 and Cetyl Stearyl Alcohol just following some cosmetic recipes online as a
starting point . Most experiments produced something that was too hard and waxy,
and when placed into water quickly started to emulsify and break down. So far
the closest I have come to matching the look and feel of the commercial product
is 91.5% Oil and 8.5% Cetyl Stearyl Alcohol, heated to combine and stirred with
a spatula. Once this cooled it looked and smelled like the commercial product at
room temperature, however I now have 2 issues I am trying to fix. Perhaps they
- At room
temperature the viscosity is good, however a small increase in temp (like
a warmer day or putting the container in your pocket) decreases the viscosity
back to oil. I was hoping to be able to have the viscosity more stable so
it stays thicker at a wider range of temperatures.
- It lacks
a “tackiness”. I would like to be able to make it ‘stickier’ so that it
holds on better when placed on an object in water. At present it has a tendency to just slide
off whatever it is placed on. I am after more of a sticky grease type consistency.
I also investigated using petroleum jelly @25% which seemed
to help a little but again it was not stable at slightly increased temperature (liquefied
immediately) and seemed to separate after a day or so. Finally, I have started
reading up on the mechanisms of liquid soap making using things like oil/potassium
hydroxide but I am not sure if this is a better path to follow.
I guess I am not even sure I am going about this in the
right way. Is what I am trying to achieve possible following this path of an
oil base or should i look at changing paths completely? If anybody could offer some advice on what I could try next I would
be very grateful and happy to learn some more!
