The record
A study of commercial Indian talc products (PMID 30916419) found tremolite asbestos in 7 of 13 sampled products: 1 of 5 in a first group and 6 of 8 in a second group.
Claim scope
The detection result in this specific 13-product convenience sample of Indian over-the-counter talc products.
What this source does not establish
A single small convenience sample cannot establish that India is the highest-risk present-day market. The paper itself states 'the country of origin in which the talc examined was sourced for production is unknown' — undercutting supply-chain attribution — and the brands are not named in the abstract.
Limitations
Carry the paper's own country-of-origin limitation alongside the 7-of-13 figure; do not generalize to the Indian market or to Indian talc sourcing.
