Morphology
The phrase is a systematic chemical name: a B1 learner who knows 'sodium', 'lauryl', and 'sulfate' can derive that it is the sodium salt of a lauryl sulfate (i.e., compositionally transparent). However, its practical meaning as a detergent/surfactant used in shampoos and its potential for skin irritation are specialized, usage-level facts that are not predictable from the constituent words alone, and 'lauryl' is a technical morpheme unfamiliar in general vocabulary.
Etymology
Sodium lauryl sulfate is a name that describes its parts: sodium is a common 'salt', lauryl comes from a fatty oil, and sulfate is the part that helps make 'foam'. So the name tells us it is a kind of 'salt' made from a fat that 'cleans' and foams, which is why it is used in many shampoos and can sometimes irritate the skin.
