Adult/infant formula

In the Ntherlands we are working on dietary content and clinical building blocks. We try to transform the dietary code list to SNOMED. I have a question about the word 'formula'. We would like to know what exactly is meant with ‘formula’, for example 442651000124102 |Adult formula (product)| or 412413001 |Infant formula (product)|. Is it correct that these are product of liquids or powder to make liquids?
