Princess Abbhantripaja is nicknamed "Khao" which means 'white' in Thai, due to her fair skin. She is regarded as one of King Rama V's most beautiful daughters, alongside her elder half-sister Princess Suddha Dibyaratana (Princess Suthathip). She is described by those who had seen her as taller than average, gentle and often smiling.

Well-educated and fluent in English, the princess cares deeply about education. She founded an all girls' school named Abbhantri Padung (or Kattiyanee Padung) school, which educates young girls, particularly the princess' own ladies-in-waiting and girls from noble or bourgeois families. She gave her old residence to be used as the school building and moved to a smaller house, in which she later died.

Princess Abbhantripaja died on 18 February 1934, at the age of 44 from influenza and complications from kidney disease.
