The 24-year-old says she finds a lot of similarity between her personality and the deodorant.
"Being on shoots can get very hectic and keep you busy. So, when I'm doing non-stop stuff throughout the day, I turn to Spinz Deo Body Spray, which keeps me fresh for long and helps me to be carefree, " Parineeti said in a statement.
"The brand's values also gel well with my personality in terms of style, attitude and appeal. So, when this opportunity came to me I was quite excited about this association, " she added.
Parineeti, cousin of Bollywood actress Priyanka Chopra, made her acting debut with "Ladies Vs Ricky Bahl". Her last project was "Ishaqzaade", and her performance was widely appreciated.
Her effervescence draws viewers to her and the brand plans to cash in on this connect, says Keshav Kumar, marketing manager of CavinKare.
"We see synergies in appointing Parineeti as the brand ambassador for Spinz as she embodies and reflects the contemporary girl of today- Fresh Face, High Spirited, Easy Going and Bustling with Energy, " Kumar said.
"Parineeti reflects the brand philosophy of 'Stop Me If You Can' while having fun with every challenge that comes in her way. Parineeti is a great fit for the brand and we are happy to be associated with such a youth icon, " he added.
Earlies, actresses Asin Thottumkal and Genelia D'Souza have endorsed the brand.
Parineeti's next projects include Maneesh Sharma's untitled project and she is also reportedly being considered for Farah Khan's project "Happy New Year".
