Abstract: Four kinds of coconut oil type dish washing detergent were prepared with xylose ester prepared from the fresh coconut testa and then formulated with other ingredients such as LAS,AES,EDTA,et al.Sensory characteristics,physical and chemical indices and product performance of the coconut oil type dish washing detergents were determined and evaluated.Results showed that the four kinds of formulated products display good stability at low temperature (-3~-10 ℃) as well as higher temperature (40 ℃).There are no bad odor,no suspension matter and no stratification.Detergency of the four formulated products are all higher than that of the conventional dish washing detergent products;while oil removal capacity of the formulation 4 product (67.27%) is the highest among the four products,which is fairly equivalent to that of the common commercial products.Adhesion,cohesion and elasticity measurement results indicated that the internal texture and structure characteristics of formulation 4 product are most close to that of the commercial product.
