Lansurf SMO
Product Category: Nonionics
Sorbitan Monooleate
Lansurf SMO is used in many application areas particularly in food contact applications. This product is also found to be readily biodegradable and would not expect to persist indefinitely in the environment. Lansurf SMO can be used singularly or in combination with the ester ethoxylates such as Lansurf SMO80.
Typically this product is extremely hydrophobic and finds use as an emulsifier in many waxes and creams for household and personal care applications. Used in combination with the ethoxylates, Lansurf SMO is used in textiles, leather treatment, silicone oils and agrochemicals.
Lansurf SMO is an excellent emulsifier for emulsion polymerization for systems such as:
