Tomamine® Acid Thickener Surfactant
Description
Tomamine Acid Thickener surfactant is a cationic
surfactant designed to build viscosity in acid
media. Tomamine Acid Thickener surfactant may
be used alone in hydrochloric acid, or in
combination with sodium chloride (salt) when
used with other acids (such as phosphoric,
sulfuric, hydrofluoric, citric, oxalic, etc.) Varying
the use level of Tomamine Acid Thickener
surfactant (and salt) will vary the viscosity build.
Tomamine Acid Thickener surfactant is not for
use in nitric acid.
Applications
• Acid bowl cleaners
• Acid truck cleaners
• Building restoration cleaners
• Other vertical surface cleaners
Advantages
• Long term viscosity stability
• Thickens both inorganic and organic acids
• Produces long-term stable viscosity
• Can replace nonionics used for wetting and
perfume solubilization
• Provides 90% corrosion inhibition in HCl
• Solubilizes easily and quickly

Formulating Hints
1. Tomamine Acid Thickener surfactant provides wetting and may eliminate the need to use nonionics
for wetting and perfume solubilization. Nonionics can affect viscosity and by eliminating their use,
better viscosity control and economics can be achieved.
2. Tomamine Acid Thickener surfactant is partially solid at room temperature, and it is critical that the
product be completely homogeneous before use in the lab or plant to enable consistent viscosity.
Slight heating or rolling of the drum is recommended.
3. For optimal results follow order of addition:
- Water
- 2% by weight of the acid
- Tomamine Acid Thickener surfactant
- Remainder of the acid
This lowers the pH of the water, thus allowing the surfactant to be more readily dispersed.
- Salt (if used)
- Perfumes and/or dyes.
4. Tomamine Acid Thickener surfactant use level should be increased as acid concentration increases.
5. If a quat is to be used for disinfectant properties, use a level of 0.1-0.2% by weight. It will affect the
viscosity.
6. Perfumes also affect the viscosity of acid systems and should be used at levels of 0.3-0.5%.
Tomamine Acid Thickener surfactant will assist in solubilizing perfumes.
