1 Scope



This stanbdard is applicable to food additive - polydimethyl siloxane (PDMS) and its emulsion.



Note: polydimethyl siloxane is a permethylated linear siloxane polymer prepared by hydrolysis of a mixture of dimethyldichlorosilane and a small amount of trimethylchlorosilane. The polydimethyl siloxane emulsion is made of the food additive polydimethyl siloxane, plus deionized water and accessory materials (see Annex A) by emulsification.
