Low Foam – Bleach Stable Surfactant |
| |
| |
MACAT AO-8 Special is a modified 30% active octyl (C8) dimethylamine oxide in water. AO-8 Special is an exceptional low foam wetting and coupling agent that is hypochlorite and alkali stable.
The exceptional performance of MACAT AO-8 Special allows for use in a wide range of markets and applications. AO-8 Special offers broad surfactant compatibility and is an effective coupling agent. Household Products, Institutional Clean-In-Place Cleaners formulations economically employ AO-8 Special for superior low foam wetting, detergency, and hypochlorite stability for unique and differentiated product performance.
The exceptional stability and wetting performance of MACAT AO-8 Special in hypochlorite solutions allows for product performance unachievable with other surfactants. Use AO-8 Special in high activity bleaching systems for enhanced cleaning, protein removal and the elimination of mold and mildew stains. Other applications include Commercial Water Treatment as a stable non-foaming wetting agent to enhance hypochlorite effectiveness.
MACAT AO-8 Special is readily biodegradable, and contains no solvents or VOCs. AO-8 Special is an efficient lipid solubilizer with an LD50 (Rats) of 3600 mg/kg and at 2.5% active, causes minimal eye irritation.

MACAT AO-8 Special is a modified 30% active octyl (C8) dimethylamine oxide in water. AO-8 Special is an exceptional low foam wetting and coupling agent that is hypochlorite and alkali stable. The graph below illustrates the expectional surface tension reduction performance of AO-8 Special in 4% NaOCl at a pH of 11.2 |

% Available Chlorine - 30 Days
This figure illustrates the hypochlorite stability of AO-8 Special versus a commonly used sodium dodecyl diphenyleneoxide disulfonate surfactant (2A1). AO-8 Special offers superior hypochlorite stability at both ambient temperature and 40°C after 30 days. Note that in the 2A1 system, all of the hypochlorite is consumed at 30 days at 40°C, and greater than half at ambient temperature.
Surface Tension - Dynes/cm
This figure illustrates the superior wetting performance of AO-8 Special versus 2A1 as a function of surface tension reduction. In addition to being low foam, AO-8 Special offers superior surface tension reduction at both ambient temperature and 40°C after 30 days for enhanced wetting, penetration and overall hypochlorite efficiency.
Formulation Guidelines
Order of addition:
-Charge water to the vessel
-Add MACAT AO-8 SPECIAL and other surfactants/ingredients
-Add NaOH/KOH to desired pH
-Finally, add hypochlorite solution |
| |
Factors that influence hypochlorite stability are Concentration (the higher the initial concentration, the lower the stability), pH (stability increases with increasing pH: less reactive/improved stability), Temperature (elevated temperatures in manufacturing/storage decrease stability), Metals (metal contamination decreases stability), and Quality of hypochlorite solution.
The substances in Macat AO-8 Special are listed on the TSCA inventory, and are listed on the following Inventories: Canada (DSL, NDSL), Europe (EINECS), Philippines (PICCS), Australia (AICS), Korea (ECL).
