Isotridecanol, Ethoxylated, is a cleaning agent or "surfactant" that can also be found in cosmetics, metal processing and lubricants. 

ISOTRIDECANOL ETHOXLATE, also called Ethoxylated Isotridecanol, is used as a wetting agent, emulsifier, and dispersing agent, e.g., in detergents, industrial & institutional cleaners, emulsion polymerization, or wax and silicon emulsions.

Detergent formulators use Ethoxylated Isotridecanol in detergents to remove dirt and deposits by surrounding dirt particles to loosen them from the surface they're attached to so they can be rinsed away.

The products of the Ethoxylated Isotridecanol series are alkyl polyethylene glycol ethers and belong to the class of nonionic surfactants. 

Isotridecanol, a C13-oxo alcohol, is the synthetic alcohol on which these products are based.

The individual grades of the Ethoxylated Isotridecanol series differ in the number n of added mol ethylene oxide per mol alcohol and cover a broad spectrum of properties applicable in various applications. 

ISOTRIDECANOL ETHOXLATEs are chemical compounds that decrease the surface or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. 

Isotridecanol Ethoxylate may function as emulsifiers, wetting agents, detergents, foaming agents, or dispersants.

In general, the Isotridecanol  Ethoxylate is characterized by the following properties:
• High detergency and surface activity
• Favourable emulsifying power
• Good hard water stability
• Chemical stability over a wide pH range • Synergistic effects with other surfactants • User-friendly viscosity and storage behavior • Favourable environmental characteristics

These properties have opened up numerous fields of applications for Ethoxylated Isotridecanol products. 
Ethoxylated Isotridecanols are used as surfactant raw materials in detergents and cleaning products as auxiliaries in textile production, metalworking, emulsifier technology, and chemical-industrial applications.

Viscosity:
Isotridecanol ethoxylates with a short EO chain are low-viscous liquids at room temperature. 
The viscosity increases with increasing degree of ethoxylation within the product series. 

Solubility, gel formation with water: 
Since the polyethylene glycol ether chain is the water-soluble constituent of Isotridecanol ethylate surfactants, the solubility in water increases with increasing degree of ethoxylation. 
The lower ethoxylates (3-6 mol EO), in which the alkyl group predominates as the hydrophobic component, are only sparingly soluble in water. 
However, they dissolve in nonpolar organic solvents and are used, for example, as w/o-emulsifiers. 
In contrast, the higher ethoxylates are readily soluble in water. 

Like all alkyl polyethylene glycol ethers, the Isotridecanol ethylates form free-flowing or solid gels when water is added in specific concentration ranges. 
During the preparation of cleaning formulations, this tendency to gel can harm processing. 
To prevent lumping and gelling, it is thus advisable to add the nonionic surfactant, use warm water, and stir well. 
Additional solvents, such as alcohols, salts, and electrolytes dissolved in water, can also suppress gel formation.


Wetting efficiency on textiles:
In detergents, the surfactants are the force that removes grease, soiling, and pigment particles from the fibers. 
The wetting efficiency on textiles is an essential criterion for assessing the performance of a surfactant. 
The products of the Isotridecanol ethylates series have high wetting efficiency on textiles, the best values being observed for Isotridecanol 6 EO to Isotridecanol 10 EO. 
The wetting effect, which, by DIN EN 1772, corresponds to the time taken for a cotton disc to sink, is shown as a function of the degree of ethoxylation. 
The shorter the sinking time, the better the wetting efficiency

Like all nonionic surfactants, Isotridecanol ethylates produce less foam than anionic products.

The favorable properties of the Isotridecanol ethylate products result in advantageous end-use features in many fields of applications. 
In particular, the favorable wetting and excellent washing and cleaning efficiency open the way for universal use.

6.5 Guideline formulations
Isotridecanol ethoxylates are essential for cleaner formulations and critical raw materials for process auxiliaries. 
Combining them with other products, e.g., anionic or cationic surfactants, can achieve synergistic and performance-enhancing effects.

Isotridecanol ethoxylates are versatile raw materials for the textile industry. 
They are used to formulate scouring, wetting, degreasing, or dying auxiliaries and lubricants or bleaches.
In the leather industry, they are used in soaking and defatting agents.

Isotridecanol ethoxylates have good emulsifying properties for various oils and solvents. 
In applications where, e.g., polydimethylsiloxanes shall be used, Isotridecanol ethoxylates yield fine dispersion water-based emulsions.
The exemplary hard water stability and their stability over a wide range of acidic and alkaline media results in various applications.

Storage and handling
Ethoxylated Isotridecanols can be stored in stainless steel tanks (steel grade 1.4541 or 1.4571), which must be heatable for the medium and higher range ethoxylates.
If the Ethoxylated Isotridecanols are stored at a low temperature, they may turn cloudy, solidify, or form layers. 
It is, therefore, advisable to heat and thoroughly mix the contents of drums or containers before partially draining some of the contents to obtain a homogeneous product.


Overheating is a key variable that could harm product quality, e.g., color quality. 
Therefore, care should be taken to store the product at the proper temperature and use a heating medium that does not produce excessive localized temperatures.
 It is generally recommended that Ethoxylated Isotridecanols should not be stored at temperatures above 50 °C for extended periods.
 Storing the products at the lowest temperature necessary to keep them fluid enough to pump and process is best.
