As a highly hydrophilic anionic polymer, Carbomer has outstanding
physical properties such as strong hygroscopicity. This kind of
white loose powder can be added into aqueous solution to expand and
swell rapidly, but it is difficult to dissolve. The pH value of 1%
aqueous dispersion is about 2.5 ~ 3.5, and the viscosity is
relatively low. When neutralized with alkali, the viscosity
gradually increases with the gradual dissolution of macromolecule
chemicals. When the concentration is low, it forms a clear solution
and forms a semitransparent emulsion gel at a relatively large
concentration. PH 6.5 ~ 7 has the greatest viscosity and
consistency. When the dispersing solution of polymer glue is
neutralized with alkali, a transparent and stable gel is
formed.
How to make the white powder carbomer **0 quickly dissolve into
water to make a transparent solution? The staff from Germany and
the biology department here are talking about the direct mixing
method for carbo gel, and hope to help the small buddy in the
industry.
Prepare the following three raw materials: carbomer **0 1g pure
water *9ml, B triethanolamine several drops, C antibacterial agent
0.5ml. Tools: mixing rod, measuring spoon / measuring cup, pH
measuring paper and an empty jar. Place carbomer **0 into the empty
jar and stir quickly until it is even. If there is obvious
agglomeration, stir it up with a stirring stick to form a fine
powder. Or only add half of the water. The remaining antibacterial
agent is added into the transparent gel. Stir in the standing room
until the carbomer **0 absorbs enough water and expands to no
caking. It takes about 2.5 hours for the gel to expand and form the
gel even state. To shorten the colloid formation time, the water
heating method can be used, while the electric heating wire is
heated, and the stirring time is about *0~*0 minutes.
Add the alkali to neutralize. Add a drop and a drop in the dripping
way. Add the edge to agitator and measure the pH value. When the pH
is 7, it is transparent gel. This step is very important. The key
to forming transparent gel is to take this action. The first
suggestion is to add a drop neutralizer - agitation - measure the
pH value, repeat this step to carbomer **0 pH value to 7 stop, so
that we can control the modulation technology, and then add
antibacterial agent and gel to finish it.
It should be noted that in general, in order to avoid compatibility
with salt or acid materials, the viscosity of 1G neutralized
polymer glue will be reduced. Usually about 1.*5g triethanolamine
is added. It is stable at pH ***0. Triethanolamine is a kind of
Alkalizer, which is used to adjust the pH value of the product. It
should be avoided to use with nitrite containing alkylating agents.
The maximum concentration is 2.5%. Avoid using in the same formula
with formaldehyde as preservative. Because triethanolamine can
cause skin irritation and sensitivity.
Desheng biochemical was founded in early ***5. Its professionals
are dedicated to R & D, production and sales of carbomer **0 /
**0. On the basis of years of practice, it has formed a production
and R & D capacity with independent intellectual property
rights and professional precipitation. Provide products, raw
materials, products and technical support solutions for more than
**0 domestic and foreign distributors and manufacturers.
