The 30-year-old reality star was covered in the cooking ingredient after an unidentified Asian woman pelted her at the launch of True Reflection at The London Hotel in West Hollywood.
Kim arrived dressed-to-the-nines, wearing a black blazer, leather trousers and a bright blue blouse, but within minutes she looked more like a dowdy housewife after a kitchen mishap.

The website reports that after the attack, Kim, who arrived at the hotel with her mother Kris Jenner, was ushered into a private room where she removed her doused jacket and brushed the flour off the rest of her outfit and long brunette locks.
The reality starlet opted to go back to the event following the fracas, and the assailant - who is said to have shouted 'fur hag' as she threw the powder - was arrested by police who were called to the scene, according to the website.

Moments before the assailant launched their attack, Kim was blissfully unaware of what was to come, happily posing for pictures and doing interviews with the press.
The attack may have quite possibly have come from a protester opposing Kim's love affair with fur.
In November Kim was the target of a PETA campaign.
The animal rights group today told TMZ it was not behind the attack - but noted that whoever did throw the flour may managed to send a message out to the reality star.
A spokesman told the website: 'PETA has tried everything from polite letters to public protests, but Kim Kardashian has not been moved by the news that animals are beaten, electrocuted, and even skinned alive for real fur garments.
' Whoever threw that flour may reach her when our polite appeals did not.'

Cheban and Kim ex-husband Humphries had a notoriously rocky relationship, which was played out on Kim's reality show: Kim and Kourtney Take New York.
'I think it's pathetic that someone would go to this length to show their support for someone,' Cheban told Us Weekly following the ordeal. 'With fans like that, who needs enemies?'

Cleaning up the mess: A hotel worker was seen vacuuming up the flour as the red-carpet cleared
Humphries representation also released a statement at the time, denying that Humphries had any involvement.
'(He) would never condone hateful and unacceptable behavior like that to anyone, in any situation,' it said.
Kim and Humphries notoriously split last year after just 72 days of marriage.
