A test method is disclosed that can be used to test cleaning products. The test method includes applying a known amount of test material to a surface, cleaning the surface and calculating the amount of allergens picked-up from the surface. The calculated amount of allergens picked-up is then corrected for several measurable variables to provide a more accurate determination of the percentage of allergens picked up with the cleaning product.

Method for determining the percentage of allergens picked up from a surface

An artificial test soil is composed of particulate, hair, and fiber components, wherein the particulate component consists of mineral, food, and plant materials, so chosen and proportioned as to correlate to a typical soil found in the home. The test soil may be used to test cleaning products by application of a known amount thereof to a surface, cleaning the surface, and determination of the amount of soil removed from the surface.

Artificial testing soil and method of testing

The addition of a quaternary ammonium phosphate compound to hair conditioning compositions substantially prevents corrosion to stainless steel manufacturing equipment employed in the preparation of the hair conditioners.

Method of eliminating the corrosivity of hair conditioning compositions

A hair care product containing in an aqueous base a quaternary compound having one erucic group. These compositions provide creme rinse formulations which have good conditioning properties and at the same time good, clean feel.

Hair treating composition containing a quaternary ammonium compound

An aerosol hair treating composition which forms a relatively stable yet collapsible foam comprising 3 to 90% by weight propellent and 97 to 10% by weight of an aqueous intermediate of 0.25 to 5% by weight polymer, 0.25 to 2% quaternary ammonium compound and water.
