Laundry Preen is a heavy-duty phosphate free laundry detergent emulsion for cleaning institutional and industrial garments. It efficiently removes mineral oils and grease and sebaceous (collar) soils from white and coloured cotton, polyester, and blends. Laundry Preen is a low alkalinity detergent which imparts longer life to garments as well as maintaining colour and brightness. It is also very effective at loosening blood soils and in institutional actions with hard water. It contains blended non-ionic and anionic surfactants for detergency and emulsification of mineral oils/greases. It works without additional emulsifiers, reducing product inventory. It contains non-phosphate builders to help comply with water discharge regulations. It is good in hard water conditions (+250 pm as CaCO3). It contains optical brighteners and anti-re-deposition agents to increase whiteness and colour retention of garments. It can be injected automatically.
