Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide–based zwitterionic surfactant, with a C 12 (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. [ 4 ]
The tariff schedule has 99 chapters under 22 sections, and various appendices for chemicals, pharmaceuticals, and intermediate chemicals for dye.Raw materials or basic substances generally appear in the early chapters and in earlier headings within a chapter, whereas highly processed goods and manufactured articles appear in later chapters and headings.
In the strict sense, the term amine oxide applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary amines. Examples of amine oxides include pyridine-N-oxide, a water-soluble crystalline solid with melting point 62–67 °C, and N-methylmorpholine N-oxide, which is an oxidant.
The process of assigning HS codes is known as "HS Classification". All products can be classified in the HS by using the General Rules for the Interpretation of the Harmonized System ("GRI") that must be applied in strict order. HS codes can be determined by a variety of factors including a product's composition, its form and its function.

LONDON/SINGAPORE (Reuters) -European shares ticked up on Thursday after falling the previous day, while Asian stocks slipped, as trading volumes thinned ahead of the U.S. Thanksgiving holiday.
Fatty alcohol are converted to their ethoxylates by treatment with ethylene oxide: [6] RCH 2 OH + n C 2 H 4 O → RCH 2 (OCH 2 CH 2) n OH. The resulting fatty alcohol ethoxylates are important surfactants. Another large class of surfactants are the sodium alkylsulfates such as sodium dodecylsulfate (SDS).
