Soap Injection And The Commercial Laundry

The injection of detergents and soaps into the commercial washing industry chain has become a major technical consideration, firstly because the environmental considerations are now so strong that they have been encased in British law and secondly they are very important in getting the right finish and thirdly because of the cost implications. A good laundry must be up to date with the latest requirements and these must be used in the processing routes. The commercial laundry suppliers have had to become very technically minded in this area and the best will be able to advise on the latest and best practices that should be adapted for the laundry market. The best suppliers have actually developed their own soap injection machines that can be fitted onto the commercial washing machines used.
So the best place to start collecting information is with the supplier and his advice should be sought on what to use and how much should be used. The second port of call is the soap and detergent manufacturers who have a wealth of experience which they will be only too willing to impart to the user. This will depend on the type of washing that is being processed. At a job interview many years ago the question was asked "why does the blue whitener make the clothes white" in a fit of inspiration and probably with some mind bending the reply came "because the blue whitener fluoresces white light". The result was the offer of a job and it seems since then that blue is a term that appears to order when washing is considered. Certainly even today most of the soap injection substances are still labelled blue. The main substance for removing stains from white products is sodium hypochlorite whilst for coloureds it is hydrogen peroxide. The hydrogen peroxide has been a substance which has caused a lot of problems with the manufacturers of products using this material as it has in the hairdressing business as this material is now very closely controlled as it is also the staple product used by terrorists in home-made explosives but a happy medium seems to have been reached.
There is a product available for every type of washing including barrier and disease type applications such as MRSA. The type of material and the quantity used is all important and needs finalising before entering the market because it is certain that the competitors have a strong position on the required practice.
