FDA warning on phenoxyethanol - Truth In Aging
Regular visitors to Truth In Aging will know that phenoxyethanol is a very common cosmetic preservative. It seems to be in just about everything I review and I usually point out that it can be a potential irritant. In Europe, many products go

- What is the optimum chemical treatment program for cooling towers?
- The composition of an optimum chemical treatment program for cooling towers on a military installation depends on the quality of the water available, the operating conditions of the cooling system, and the environmental constraints placed on treatment chemicals in the blowdown water (effluent discharge limitations).
- Why do cooling towers need chemical treatment?
- By maintaining proper water chemistry, chemical treatment helps cooling towers achieve their full operational lifetime. Some of the most prevalent water chemistry problems in cooling towers are mineral scaling, especially from elevated calcium carbonate and silica levels in feedwater.
- What are cooling tower water systems?
- The following are key terms and definitions related to cooling tower water systems and factors to consider when designing cooling tower water systems. This is the amount of water – in gallons per minute (gpm) – lost to the evaporation as the air passes through the evaporating cooling tower. It is roughly calculated using the following formula.
- Do cooling towers have water chemistry problems?
- Some of the most prevalent water chemistry problems in cooling towers are mineral scaling, especially from elevated calcium carbonate and silica levels in feedwater. We’ve all seen scale on our household faucets—that hard white crust that builds up over time – which is the same scale formation that can occur in cooling towers.
