Croda Inc announced that it is offering five products that have been registered as HX-1 ingredients for incidental food contact by NSF International. In order to gain NSF HX-1 approval, the lubricant manufacturer must prove that all ingredients in the formulation comply with 21 CFR. The program is generally accepted worldwide for the registration of incidental food contact lubricants.
The following products can serve as rust inhibitors for food grade applications and have earned the NSF HX-1 registration:
•Tween 20 – nonionic surfactant, HLB 17
•Tween 40 – nonionic surfactant, HLB 16
•Tween 60 – nonionic surfactant, HLB 15
•Tween 80 – nonionic surfactant, HLB 15
•Tween 85 – nonionic surfactant, HLB 11
All of these materials are ethoxylated sorbitan esters based on natural fatty acid. Croda stated that they are effective at forming oil in water emulsions, particularly when used in combination with the company’s Span range of non-ethoxylated precursors. Additionally, Croda noted that these products are all high HLB surfactants, which are inherently biodegradable and suitable for incidental food contact.
