Oh, I know you are bored by my posts on sunscreen. But, yes, I am obsessed. Did you know applying sunscreen can even help you with the pores problem? Yes!!! So, next time check out a good sunscreen And, now, a little about Indian regulations on sunscreen.
In India, sunscreen is considered a cosmetic and there is no maximum SPF rating. India has different registration lead times for sunscreens depending on if the product is made locally (3 months), or for import (9 months). India requires the manufacturer to release the full product formulation, including the quantitative formula with declaration and disclosure of functions of ingredients. All label text must be disclosed during the registration process along with the product specs, manufacturing process, chemical and microbiological testing methods and any data supporting product claims. India requires the manufacture to run a minimum of 2 pilot batches before registering a sunscreen. India requires specific stability testing requirements to show shelf life of the sunscreen. Testing may be done using accelerated methods of exposure to extreme heat. However, any data that is accelerated also needs to be confirmed by real time testing, so the process takes longer than the 3 or 9 months since the real time data (for up to a 3 year shelf life) needs to be available to register.
