Procter & Gamble has agreed to halve the wet strength of Charmin toilet tissue in the wake of mounting concerns that the product could block sewerage systems. The U-turn follows agreement between the Association of Makers of Soft Toilet Tissue Products over an industry standard for flushability. P&G admitted sewers might become blocked if all paper products were as strong as Charmin, but said: "It's not about one brand. It's an industry problem." Kimberly-Clark's Lyn Mayes said the AMSTP had agreed one rule should apply to all "otherwise it would be like saying it's OK to be a drunk driver as long as you're the only car on the road". {{NEWS }}
