ALKLEEN SAFETY LIQUID is a non caustic heavy duty alkaline cleaner formulated for cleaning animal and vegetable oils and fats from tanks with special coatings including zinc etc. This product is specifically designed to improve cleaning efficiency while overcoming the limitations imposed by caustic based cleaning compounds.

ALKLEEN SAFETY LIQUID can also be used as a deodorizing wash in all applications. ALKLEEN SAFETY LIQUID adds a substantial degree of safety to the washing operation.

• Safety in Application - minimizes the extreme hazards to ships personnel in handing caustic based materials.

• Safety in Preventing Accelerated Corrosion - ALKLEEN SAFETY LIQUID in addition to being free of caustic, has corrosion inhibitors incorporated in the formulation to prevent corrosion of metals such as zinc, aluminium, copper, brass and tin. This is a critical requirement in cleaning tanks which utilize metals such as zinc in protective tank coatings.

ADVANTAGES

ALKLEEN SAFETY LIQUID performs four basic cleaning functions.

1.Saponifying Animal and Vegetable Oils and Fats. Saponification is the alkali induced process of splitting animal or vegetable fats to form a soluble soap. ALKLEEN SAFETY LIQUID breaks oil into fine droplets which are saponified easily. This is an advantage over caustic shich has a higher percentage of alkali but which only sponifles the surface of the oil drops thus forming a protective shield around the oil which prevents complete saponification.

2. Emulsifying Mineral Oils and Grease.
Oil which cannot be saponified are removed by emulsification. ALKLEEN SAFETY LIQUID homogenizes grease oil and fat particles into small sizes and disperses them evenly in water. Particles are kept segregated and prevented from recombining and reattaching to the cleaned surface.

3. Delloculation.
Solid dirts are not removed by saponification or emulsification. ALKLEEN OSAFETY LIQUID breaks up agglomerated masses into very fine particles which repel each other.

4. Suspension and prevention of Redeposition.

ALKLEEN SAFETY LIQUID prevents redeposition of soil preventing setting and reattachment to the surface being cleaning. Caustic soda and soda ash do not have these properties and soil settles out promptly.

APPLICATION

Our general recommendations are for cleaning tanks for edible cargos to a degree of cleanliness where no contaminants are to be tolerated in the next cargo Recirgulate or inject ALKLEEN SAFETY LIQUID at 5% strength in fresh water after the tanks have been striped and rinsed Modified procedures are required with drying oils.

ALKLEEN SAFETY LIQUID can also be applied neat in spray applications followed by a rinse. A number of variables related to each individual cleaning operation can have a major influence on results. A review of the chemistry of the last product carried is particularly important in recommending optimum cleaning concentrations, methods of application and temperatures of rinse water and ALKLEEN solution ROCHEM SERVICE ENGINEERS are available to review your specific problem and offer recommendations for the best results at minimum costs.

HANDLING

Non-flammable, non-explosive and non-toxic. Not strongly alkaline however should be handled with care if there is risk of product splashing into the eyes goggles should be worn. Advisable to wear gloves and protective clothing. For some persons the use of cold cream based on lanolin or petroleum jelly rubbed ion exposed skin provides protection.
