Didecyldimethylammonium Chloride (DDAC) Testing
Oxford Analytical are a GLP approved facility for all your DDAC testing requirements.
Didecyldimethylammonium chloride (DDAC) is an antiseptic/disinfectant that is used in many biocidal applications. It causes disruption of intermolecular interactions and dissociation of lipid bilayers. It is a broad spectrum bactericidal and fungicidal. DDAC can be used as disinfectant cleaner for linen. It is also recommended for use in hospitals, hotels and industries. Furthermore it is used in gynaecology, surgery, ophthalmology, pediatrics and OT. It can be used for the sterilization of surgical instruments, endoscopes and surface disinfection.
DDAC is a modern and safe biocide. It features broad spectrum activity against both gram positive and gram negative bacteria, fungicide and mildewcide. DDAC is active against enveloped viruses (e.g. Hepatitis B, HIV). Also present is a tolerance for anionic contaminants, high tolerance to hard water. It also maintains efficacy in presence of heavy organic soiling such as blood and protein, good surfactant and wetting properties.
This substance is approved for use as a biocide in the EEA and/or Switzerland, for: veterinary hygiene, food and animals feeds, wood preservation.
This substance is being reviewed for use as a biocide in the EEA and/or Switzerland, for: human hygiene, disinfection, product preservation, preservation for construction materials, preservation for liquid systems, controlling slimes.
How can we help with your testing requirements?
We have established methods using LC/MS for various types of DDAC containing products and can carry out routine analysis or other physical testing including storage stability.
Whether DACC is a single active or part of something more complex we can develop and validate methods to support your registration requirements.
Helping you through the Biocidal Products Regulations to be able to market your product and providing stability and safety data through various physical and chemical testing.
These tests can all be done in compliance with GLP where required, and if the formal certification is not required you can still rest assured that all of our processes are carried out following the same high-quality standards even when outside of GLP.
We partner with consultants and other laboratories to support additional testing requirements too – so if we can’t do it, we will help you find someone who can through our trusted network.
Please contact us for further discussion of your particular DDAC testing requirements.

New regulations around Biocides came into place in 2012 . We have since therefore worked with industry to support registration needs conducting 5 batch analysis, routine testing, storage stability, physical testing and more on a wide range of Biocides.
Biostimulants are a wonderful new way to protect our plants and wildlife by using nature to protect itself. They are natural substances harnessed for their characteristics. After that they are developed into products that can be applied to seeds, plants and soils in order to stimulate natural growth.
We have worked with consultants and direct customers for many years supporting their Agrochemical registration testing requirements under global regulations. Find out more here
We can design storage stability studies with or without GLP accreditation under the Biocides, Plant Protection, or ICH guidelines to support registration around the world. Find out more here
Need data for registration or a safety data sheet?
From explosive properties through to partition co-efficient, we cover a wider range of physical tests and can also develop our own in-house methods for novel experiments.
We use a range of methods from CIPAC, ASTM, ISO, OPPTS, OECD and more to meet global regulatory requirements. Find out more here
We can cover elemental to extremely low levels. For instance if you just need to identify, quantify, or fully validate a method. Our ICP systems cover a wide range of elements often working on 10+ elements at the same time.
We regularly work on Silver, Lead, Arsenic, Chromium, Cadmium, Mercury, Copper, Boron and Sodium to name a few. Our list of capabilities stretches much longer! Find out more here
We can carry out impurity profiling, product screening, method validation and 5 batch analysis or Technical Equivalence studies to meet your registration needs. Our team develop tailored methods for your products and can also support with structural identification requirements.
We have many years of experience with successful studies over many compounds from Citric Acid to Pyrethrins covering elemental impurities, isomers, and additives of all types.
Whether your product is a TC, or TK we can help. Find out more here
We have been developing tailored methods at affordable prices for many years. Our chemists have developed thousands of methods over the years from simple single actives to complex products covering a wide range of levels and product types.
We can also validate already developed methods or support you through your own method development journey via consultation.
Our validation expertise covers global requirements including SANCO/3030/99, SANTE/2020/12830 and ICH Q2, OPPTS 830.1800 and APVMA among others. Find out more here
The fertiliser market is well established but under scrutiny with the introduction of new regulations demanding more rigorous testing and reducing acceptable levels of elements.
We are one of few labs that can offer the full suite of Fertiliser testing including Inorganic Arsenic, and Chromium VI. Find out more here
Need routine quality checks, one offs or concerned about contamination?
New regulations to meet? We often take on complex novel projects and it is what we are known for! Our chemists enjoy doing something different! Find out more here
