Profile Liquid detergents are convenience products, compared with powdered detergent dissolve more rapidly, particularly in cold water, they generate less dust. It is not surprising, therefore, those liquid forms of household cleaning product developed by manufacturers. With the exception of fabric softeners and shampoos, the solid form of cleaning preceded the liquid form. This is used as manual and automatic dishwashing, laundry general personal washing products. As a result, the technical history of liquid detergents is to a large extent one of emulating the performance features of the powder models. Generally, there are two types of liquid detergents: 1. Light duty liquid detergent. 2. Heavy duty liquid detergent. Production Procedure For manufacturing liquid detergent, both the batch as well as continuous blending processes is used. Both batch and continuous blending processes are used to manufacture liquid and gel cleaning products. Stabilizers may be added during manufacturing to ensure the uniformity and stability of the finished product. In a typical continuous process, dry and liquid ingredients are added and blended to a uniform mixture using in-line or static mixers. Recently, more concentrated liquid products have been introduced and a technique for developing these products is through the use of new high-energy mixing processes in combination with stabilizing agents. To make liquid detergent, the dry powder is simply mixed back in with a solution consisting of chemicals and water, called as solubilizers. These chemicals help the water and detergent to blend together more evenly. A reflection rate of 98 % is considered as quite good and shows that the detergent has cleaned properly. Application Liquid Detergents are formulated with the intension of their following end uses: 1. House hold washing liquid mainly for dish, utensils etc., washing. 2. Light duty laundering for synthetic and woollen fabrics. 3. For scouring mineral oiled goods of woollen or worsted piece fabrics. 4. Rug cleaning shampoos. Market Potential The liquid form for household detergents is gaining market share in many world markets particularly for dish-washing and light-duty applications. Moreover, the personal care products in liquid form have a substantial share of the market and can be manufactured in the same plants as liquid detergents. Independently from the type of liquid detergent or personal care product and their specific targeted uses, the manufacturing of liquid detergents should be based on processes, equipment and operation sequences in compliance with the chemical and physical demand of these products.
