Very well biodegradable sequestering and dispersing agent
PERIQUEST BSD can be used in a wide variety of applications which need high soil suspension capacity and detergency, for example in washing and scouring of cotton articles, in dyeing cotton with reactive dyes and in soaping of reactive, vat and sulfur dyestuffs.
The ability of removing cotton accompanying substances is improved thus saving the number of rinses required.
PERIQUEST BSD is used as a stabilizer for bleaching with peroxide. Good hydrophilic properties and high degrees of whiteness are the result.
In continuous indigo dyeing processes PERIQUEST BSD can be used as well. Its application is recommendable in all process steps which require a very good sequestering power with high pH values, e.g. in the pretreatment, the indigo dyeing itself, or the bottoming and topping with sulphur dyes.
PERIQUEST BSD contains very well degradable sequestering and complexing substances and has superior calcium and iron binding properties. PERIQUEST BSD neither contains nitrogen nor phosphorus.
PERIQUEST BSD is an excellent dispersing agent, it increases the detergency and the capacity of baths to keep removed soil in dispersion. This is of particular significance for short bath ratio systems. The dispersing and adsorption effect serves to displace and keep in solution fibre accompanying substances, preparations and unfixed dyestuffs.
PERIQUEST BSD can also be used for stabilizing of peroxide in the bleaching.
Despite its complexing components, PERIQUEST BSD does not affect dyeing processes using metal containing dyes.
PERIQUEST BSD has a capacity of binding calcium at pH 10 of 50 mg calcium per g PERIQUEST BSD.
The capacity of binding iron at pH 10 is 700 mg iron (III) per g PERIQUEST BSD.
