EDIT: my napkin math turns out to have been closer to "toilet paper math" because it was completely wrong. See child comment for details.
Interestingly, Charmin as a brand has revenue around ~2.5B[1], which when multiplied by P&G's P/E ratio of ~25[2] gives you a rough idea of the brand's value as part of the parent company's market cap: 60B.
So, the paper you wipe your ass with is worth about 3 snapchats.
The E in P/E is earnings (profit), not revenue. Your valuation is probably an order of magnitude high. Also your first link uses the vague "sales" which could mean end retail sales, in which case revenue to P&G would be even lower.
Procter and Gamble produces a whole lot more than toilet paper. They're one of the three or so megacorps that makes almost all of the consumer household goods sold in the US.
If you use Charmin to wipe your ass, they are owned by P&G, which has a market cap of $230B.
