TRITON X-100

CAS Number: 9002-93-1
Molecular Formula: (c2h4o)x • C14H22O
Molecular Weight: 250.382 g/mol

Triton X-100 (C14H22O(C2H4O)n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average Triton X-100 has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group.
The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group.

Triton X-100 is closely related to IGEPAL CA-630 or former Nonidet P-40, which might differ from Triton X-100 mainly in having slightly shorter ethylene oxide chains.
Thus Triton X-100 is slightly more hydrophilic than Igepal CA-630; these two detergents may not be considered to be functionally interchangeable for most applications.

Triton X-100 is a common non-ionic surfactant and emulsifier which is often used in biochemical applications to solubilize proteins.
Triton X-100 is considered a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent.

Triton X-100 is utilized for lysing cells to extract protein and cellular organelles.
Triton X-100 can also permeabilize the living cell membrane for transfection.
Triton X-100 has hemolytic property and is used for DNA extraction.

Nonionic surfactant for use in household and industrial cleaners, paints and coatings, and pulp and paper processing

Triton X-100 (Polyethylene Glycol Octyl Phenyl Ether) is a non-ionic surfactant (or detergent).
The molecular weight is 646.86 (C34H62O11).
Triton X-100 can dissolve lipid to increase the permeability of cell membrane to antibody.

The concentration of Triton X-100 in immunocytochemistry is 1% or 0.3%, in which 1% Triton X-100 is usually used for rinsing tissue samples, 0.3% Triton X-100 is usually used for diluting serum, 0.1% Triton X-100 is commonly used for lamp (loop mediated isothermal amplification), preparation of BSA, etc.

X-100 is a nonionic detergent, 100% active ingredient, which is often used in biochemical applications to solubilize proteins.
Triton X-100 has no antimicrobial properties.

Triton X-100 is considered a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent.
Triton X-100 does absorb in the ultraviolet region of the spectrum, however, so can interfere with protein quantitation.

A number of polymeric resins have been used to remove X-100 from solution, including Amberlite hydrophobic XAD resins and Rezorian A161 cartridges.
The "X" series of Triton detergents are produced from octylphenol polymerized with ethylene oxide.

The number ("-100") relates only indirectly to the number of ethylene oxide units in the structure.
X100 has an "average of 9.5" ethylene oxide units per molecule, with an average molecular weight of 625.

In addition, lower and higher mole adducts will be present in lesser amounts, varying slightly within supplier's standard manufacturing conditions.
No antioxidants are added by Sigma or the manufacturer, but commercial preparations of Triton X-100 have been found to contain peroxides up to 0.22% hydrogen peroxide (H2O2) equivalents.

These impurities may interfere with biological reactions.
Sigma offers X-100-PC and X-100R-PC as biological grade alternatives.

Physical Description of Triton X-100:
Light yellow viscous liquid; Colorless to pale yellow viscous liquid with a slight odor.

Regulation in the European Union of Triton X-100:
In December 2012, the European Chemicals Agency (ECHA) included the substance group “4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated” – which includes Triton X-100 – in the Candidate List of substances of very high concern of the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation which addresses the production, import and use of chemical substances and their potential impacts on human health and the environment.
A Triton X-100 degradation product has indeed turned out to be ecotoxic as Triton X-100 possesses hormone-like (estrogeno-mimetic) activity that may act on wildlife.
The ECHA finally included the substance group in the Authorisation List (Annex XIV), mandating the pharmaceutical and other industries to replace this detergent by the “sunset date” January 4, 2021, thereby affecting EU manufacturers, importers, and downstream users, as well as non-European manufacturers exporting their products into the EU.

Alternatives for viral inactivation of Triton X-100:
Since the inclusion of Triton X-100 in the candidate list of substances of very high concern for authorization, pharmaceutical companies, as well as bioprocessing research groups, are in need of an alternative detergent which must at the same time be eco-friendly and effective.
Ideally, a Triton X-100 replacement should generate minimal manufacturing process change, because only then the necessary updates of regulatory filings for medicines could be realized without additional animal experiments or even clinical studies.

Therefore, an alternative virus-inactivating detergent should have physico-chemical properties similar to Triton X-100, be soluble, easy to remove, and eco-friendly, and not degrade to toxic metabolites.
In a recent study, two alternatives for antiviral treatment in biopharmaceutical manufacturing have been identified: Triton X-100 reduced, as well as a novel compound which was named Nereid (after the mermaids in Greek mythology).

As reflected by the name, Nereid can be seen as just another relative of the Triton X-100 family, however, due to a small molecular difference, Triton X-100 does not degrade into phenolic compounds the way that Triton X-100 does.
The virus inactivation studies comprised experiments with several relevant viruses under various conditions.

Triton X-100 turned out that at room temperature, where most virus inactivation steps in biopharmaceutical manufacturing are conducted, both Triton X-100 reduced and Nereid showed similar virus inactivating performances as Triton X-100.
In contrast, for some processes that are conducted at cold temperatures, Nereid and Triton X-100 gave better results than Triton X-100 reduced.

Biochem/physiol Actions of Triton X-100:

Addition of EDTA and butylated hydroxytoluene will help to prevent oxidation.
Use 1 mole of butylated hydroxytoluene per 500 moles of detergent to prevent autooxidation.

Instructions of Triton X-100:
Triton X-100 is 100% Triton X-100 solution.
Triton X-100 is recommended to prepare 30% Triton X-100 stock solution, and dilute to the required concentration when Triton X-100 is needed.

Preparation of 30% Triton X-100 stock solution: Take 3 ml of Triton X-100 and add Triton X-100 to 7 ml of 1× PBS buffer, the mixture is 30% Triton X-100.

Dilute the 30% Triton X-100 stock solution with 1× PBS buffer to the required concentration before use.

Structure of Triton X-100:
Triton X-100 has a structure very similar to those of Igepal CA-630 and of Nonidet P-40 (no longer commercially available), and the names are sometimes reported as synonyms.
However, Triton X-100 is slightly more hydrophilic than Igepal CA-630; these two detergents are NOT considered to be functionally interchangeable in most applications.

Solublity/Stability of Triton X-100:
Triton X-100 is soluble in all proportions at 25°C in water, benzene, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethanol, isopropanol, and ethylene dichloride.
Sigma assays dissolves 1 mL X-100 in 10 mL water to give a clear to slightly hazy solution, from clear to slightly yellow in appearance.

Solutions are stable to autoclaving.
At certain concentrations the solutions may be cloudy but dispersible above the cloud point; they should clear with stirring upon cooling.

However, any ethylene oxide polymer can form trace peroxides on exposure to oxygen.
These impurities may interfere with biological reactions.
Sigma offers X-100-PC and X-100R-PC as biological grade alternatives.

Physical properties of Triton X-100:
Undiluted Triton X-100 is a clear viscous fluid (less viscous than undiluted glycerol).
Undiluted Triton X-100 has a viscosity of about 270 centipoise at 25 °C which comes down to about 80 centipoise at 50 °C.

Triton X-100 is soluble at 25 °C in water, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, and ethylene dichloride.
Triton X-100 is insoluble in kerosene, mineral spirits, and naphtha, unless a coupling agent like oleic acid is used.

Triton X-100tm is a very stable material, assumed to be stable for years if stored sealed.
Triton X-100 is a clear to slightly hazy, colorless to light yellow liquid (color by APHA = 100).

Specific gravity: 1.065 at 25°C (Approx. 1.07 g/mL)

Specific Usage Notes of Triton X-100:
For lysing cells, typically about 0.1% X-100 solution in water will be sufficient, and even up to 0.5% concentrations will usually not harm most enzymes being isolated.
