Peracetic Acid is a liquid organic peroxide with strong oxidising and antimicrobial properties. Commercial Peracetic Acid is generally supplied as an aqueous solution containing Peracetic Acid together with water, Hydrogen Peroxide and Acetic Acid, with the exact composition depending on the commercial grade.
Peracetic Acid is primarily valued for its ability to provide rapid antimicrobial activity and oxidation. It can be used in applications where microbial control and oxidation are required.
Because Peracetic Acid is a reactive oxidising material, its suitability for a particular cosmetic application must be evaluated carefully according to concentration, formulation composition, exposure conditions, packaging compatibility and applicable regulations.
Peracetic Acid is an organic peroxide formed from Acetic Acid and Hydrogen Peroxide. It is commonly supplied as a liquid solution rather than as a pure isolated material.
Its strong oxidation capability gives it broad antimicrobial activity against microorganisms including bacteria, fungi and other microbial contaminants.
Peracetic Acid is particularly sensitive to temperature, contamination and storage conditions. Commercial solutions are therefore manufactured and packaged with appropriate stabilisation and handling requirements.
Peracetic Acid is primarily valued for its strong antimicrobial activity.
Its oxidative chemistry allows it to damage microbial cellular components and contribute to rapid microbial inactivation.
It can be effective against a broad range of microorganisms, depending on concentration, temperature, contact time and application conditions.
For any formulation or process application, antimicrobial performance should be validated under the actual conditions of use.
Peracetic Acid is a strong oxidising material.
Its oxidation properties are responsible for much of its antimicrobial activity and also determine its compatibility with other formulation ingredients.
Because of this strong reactivity, formulators should carefully evaluate compatibility with:
Peracetic Acid may be relevant to selected controlled antimicrobial or sanitisation applications associated with cosmetic and personal-care manufacturing.
However, it should not automatically be described as a conventional leave-on cosmetic preservative.
Its high oxidative reactivity means that the exact concentration, contact conditions and intended application must be evaluated before incorporating it into a finished cosmetic formulation.
Commercial Peracetic Acid solutions are generally supplied as a clear, colourless to slightly coloured liquid, depending on concentration and grade.
The final appearance specification should follow the selected commercial product's COA/TDS.
Peracetic Acid concentration is one of the most important quality parameters.
Commercial products are available at different concentrations, so the exact active content must be specified according to the selected grade.
Do not use one universal concentration for all Peracetic Acid products.
Commercial Peracetic Acid solutions can contain residual or equilibrium Hydrogen Peroxide.
The Hydrogen Peroxide content should therefore be controlled according to the exact commercial formulation and COA.
Acetic Acid can also be present in commercial Peracetic Acid solutions.
The exact Acetic Acid concentration is grade-specific and should be obtained from the supplier's specification.
Peracetic Acid solutions are acidic. The exact pH depends on concentration and formulation composition.
The final raw-material specification should therefore use the applicable commercial-grade specification.
Peracetic Acid is relatively unstable compared with many conventional cosmetic raw materials.
Decomposition can be accelerated by:
Appropriate stabilisation and compatible packaging are therefore important.
Peracetic Acid should be handled using controlled procedures appropriate to the concentration and grade.
It should not be mixed indiscriminately with other formulation ingredients because its oxidising properties can result in chemical reactions.
Compatibility should be evaluated carefully with:
Peracetic Acid should be stored according to the supplier's current SDS/TDS.
Storage should generally involve suitable compatible containers, temperature control, protection from direct sunlight and prevention of contamination.
Depending on the grade and regulatory approval, Peracetic Acid can be considered for:
The exact application must be determined according to the concentration, grade and applicable regulations.
Peracetic Acid is a strong oxidising organic peroxide commonly supplied as an aqueous liquid solution and valued for antimicrobial activity.
The CAS number of Peracetic Acid is 79-21-0.
Yes. Commercial Peracetic Acid is generally supplied as a liquid solution.
Commercial Peracetic Acid solutions are generally clear and colourless to slightly coloured, depending on grade and concentration.
It is primarily used for its strong oxidising and antimicrobial properties in controlled applications.
Peracetic Acid should not automatically be classified as a conventional cosmetic preservative. Its primary relevance is strong antimicrobial and oxidising activity, and its suitability depends on the intended application and applicable regulations.
Commercial Peracetic Acid solutions commonly contain Hydrogen Peroxide as part of the equilibrium mixture. The exact concentration is grade-specific.
Commercial solutions commonly contain Acetic Acid. The exact concentration depends on the commercial grade.
Peracetic Acid is relatively reactive and can decompose under unsuitable conditions. Heat, contamination, light and certain metals can accelerate decomposition.
It should be stored according to the supplier's SDS/TDS using compatible packaging and appropriate temperature and contamination controls.
The buyer should verify CAS identity, Peracetic Acid active content, Hydrogen Peroxide content, Acetic Acid content, appearance, colour, density, acidity/pH, stabiliser content, impurity profile, packaging compatibility, storage requirements and shelf life through the supplier's COA/TDS/SDS.
