Hello aspirant, hope you are doing good.

So, firstly, I want to say kudos to you for choosing a rather different area for pursuing your higher education, it's really good that you are thinking of something unique. This branch of engineering is not very popular in India yet, but it still is a very growing topic. Aspiring students should have passed H.S.C. Exam or equivalent recognized exam with English, Physics, Chemistry and Biology with minimum 50% marks for open category and 45 % marks for reserved category.

There are mainly two top colleges in India for B.Tech in cosmetic technology :

1.

Kamla Nehru Mahavidyalaya, Nagpur

2.

Mahila Mahavidyalaya, Nagpur

3. North Maharashtra University (https://targetstudy.com/university/190/north-maharashtra-university/) , Jalgaon

4. Rashtrasant Tukadoji Maharaj Nagpur University - RTMNU (https://targetstudy.com/university/189/rashtrasant-tukadoji-maharaj-nagpur-university/) , Nagpur

To be eligible for getting into these colleges, apart from the required criteria, you should also have a good sense of aesthetics and be really creative,should have good and polite way of expression .

Hope this helps you. Good Luck !!
