Surface active agents. Determination of 1,4-dioxan residues in surfactants obtained from epoxyethane by gas chromatography algolia-ignore This part of ISO 21527

This part of ISO 21527 specifies a horizontal method for the enumeration of viable yeasts and moulds in products intended for human consumption or feeding of animals that have a water activity greater than 0

NOTE Where the term “bar” is used in this standard

This part of ISO/IEC 12087 also defines those “specializations” or “delineations” of the generic imaging architecture that are required to support IPI-PIKS and IPI-IIF

Surface active agents. Determination of 1,4-dioxan residues in surfactants obtained from epoxyethane by gas chromatography algolia-ignore This part of ISO 215271 Scope This International Standard provides a method for the determination of 1,4 dioxane residues in surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates. The method is applicable for samples containing 1,4 dioxane more than 5 mg kg. For samples containing 1,4 dioxane more than 100 mg kg, the sample solutions should be diluted to appropriate concentration.
