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

Well-educated and fluent in English, the princess cared deeply about education. She founded an all girls' school named Abbhantri Padung (or Kattiyanee Padung) school, which educated 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.
