It appears in the form of white granules.

Food
Ingredient included in the list of European food additives as E442, with an emulsifying function, developed to replace lecithin, particularly in chocolate.

Safety
Ammonium phosphatides (E442) is authorised as a food additive in the European Union (EU) in accordance with Annex II and Annex III to Regulation (EC) No 1333/2008 on food additives and specific purity criteria have been defined in the Commission Regulation (EU) No 231/2012.
Following a request from the European Commission, the EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to re‐evaluate the safety of ammonium phosphatides (E442) when used as a food additive.
Toxicological data for ammonium phosphatides were evaluated by the Scientific Committee on Food (SCF) in 1978. The Committee established an acceptable daily intake (ADI) of 30 mg/kg body weight (bw) per day.
Based on the available database, the Panel considered that there is no reason to revise the current ADI for ammonium phosphatides of 30 mg/kg bw per day derived from a NOAEL of 3,000 mg/kg bw per day in the rat carcinogenicity study and applying an uncertainty factor of 100.
