Detergency Performance
TERGITOL 15-S-9 Surfactant provides excellent cleaning of hard and soft surfaces. 
TERGITOL 15-S-9 Surfactant meets or exceeds competitive ethoxylate surfactants in hard-surface cleaning tests. 
The outstanding formulating and handling characteristics of TERGITOL 15-S-9 Surfactant, combined with its excellent performance, make it a surfactant of choice for hard-surface cleaner products.

Detergency values for a mineral oil/carbon black standard soil cloth available from Testfabrics Inc. were determined for TERGITOL 15-S-9 Surfactant and the competitive ethoxylates. 
All of the nonionic surfactants perform well, but even among these tough competitors TERGITOL 15-S-9 Surfactant exhibits excellent performance. 
The outstanding cleaning properties of this surfactant, combined with its desirable formulating and handling characteristics, low odor, and biodegradability, make TERGITOL 15-S-9 Surfactant an ideal surfactant for high-performance detergent products


Effect of Electrolytes on Cloud Point

TERGITOL 15-S-9 Surfactant exhibits a cloud point depression in the presence of significant concentrations of most electrolytes. 
Since solubility is related to alkalinity, sodium hydroxide has a much greater effect on solubility than do more neutral salts such as sodium carbonate and sodium chloride. 
This “salting out” effect is generally attributed to the dehydration of the ethylene oxide chains, thereby resulting in the disruption of the hydrogen bonding forces responsible for maintaining water solubility. 
The amount of salt that can be tolerated by a nonionic surfactant is proportional to the number of sites available for hydrogen bonding along the chain, and this in turn is dependent upon the degree of ethoxylation. 
TERGITOL 15-S-9 Surfactant is typical of detergent-range alcohol ethoxylates in its ability to tolerate strong electrolytes.
The characteristic cloud point reduction in the presence of electrolytes is sometimes  utilized to increase the low-temperature surface activity of TERGITOL 15-S-9 Surfactant, and it is also useful when an application requires the surfactant to be above its cloud point such as in some textile scouring operations. 
Consequently TERGITOL 15-S-9 Surfactant is well suited for applications requiring high surface activity at moderate temperatures in the presence of low levels of electrolytes


Storage and Handling

TERGITOL Specialty Surfactants are stable, high flash point products manufactured to meet exacting standards of quality. 
They must be handled and stored properly to prevent degradation or contamination and to ensure maximum performance in your application.


Storage
Under anhydrous conditions, store in carbon steel, baked phenolic-lined steel, fiberglass-reinforced polyester, tinned iron, or polyethylene. 
To avoid discoloration, do not use copper, copper alloys (brass, bronze), zinc, or galvanized iron.
When water is added, the resulting product is more corrosive to commonly used metals and should be stored in stainless steel (type 304 or 316), baked phenolic-lined steel, fiberglass-reinforced polyester, polyethylene or polypropylene.
Store under nitrogen to avoid degradation which causes undesirable color and odor.
Store under air (without nitrogen blanket) only for short-term storage, when temperature is less than 90°F. 
Slow degradation will occur under air storage. 
A desiccant unit may be installed in the vent line to dry incoming air.


Handling
TERGITOL 15-S-9 Surfactant has a typical pour point of 9°C (48°F) and is a low-viscosity liquid at room temperature (60 cP at 25°C). 
While it is unlikely that heated storage and handling facilities will be required for the neat surfactant, some formulations containing TERGITOL 15-S-9 Surfactant may require heat to maintain adequate handling and/or stability.
Use mild heating, preferably with circulation or agitation, since surfactants are subject to discoloration when overheated. 
Heat with warm water or low watt-density electrical heating tape, so that the container temperature will not exceed 50°C (122°F).
Low-pressure steam is acceptable, as long as circulation or agitation is provided.
Avoid bayonet heaters because high temperatures can be generated on their heating surfaces.
Standard all-iron valves and centrifugal pumps are commonly used for product transfer service. 
Ball valves with “Teflon” seals can be used for “on-off” valves.
