Properties of Cresylic/Phenolic Combination

Property

Benefits

Odour Strong phenolic odour

High order

disinfectant

Takes low ppm for effect

Broad spectrum Kills bacteria, fungi, many viruses

Volatility Phenolics not volatile, cresylics volatile.

Residual germicidal action. Odours may

linger several days. Useful for premise

disinfection but not hatchery or other

indoor areas.

Organic soil

tolerance

Very good

Storage stability Good

Kill time Fast

Corrosivity Safe for most metals and premise

surfaces. May soften rubber seals and

some plastic materials.

Hard water

tolerance

Excellent

Toxicity Concentrate strong irritant. Use

solutions mild skin and eye irritants.

Recommended

use areas

Farm premise clean up. Not used in

hatchery or in egg rooms.

Biodegradable Cresylics degrade. Phenolics, poor.

Properties of Saponified Cresylic Disinfectants

Property

Benefits

Odour Strong phenolic odour

Low order

disinfectant

Takes high ppm for effect

Not broad

spectrum

Kills gram (-ve), not gram (+ve)

bacteria

Volatility Slowly volatile. Odours linger long

time. Not acceptable for indoor or

frequent use.

Organic soil

tolerance

Good

Storage stability Good

Kill time Fast, where effective

Corrosivity

Cresylics are saponified. Safe for most

metals and premise surfaces. May

soften rubber seals and some plastic

materials.

Hard water

tolerance

Good

Toxicity Concentrate strong irritant. Use

solutions mild skin and eye irritants.

Biodegradable Yes
