Black Liquor Soap

A natural intermediate byproduct of kraft pulping, black liquor soap is the rosin and fatty acid content that floats to the top as black liquor is left to settle. It is skimmed off and can be used as a raw material for tall oil production. Black liquor soap can be somewhat abrasive and range in viscosity from 22 to 5500 cP, depending on the temperature it is handled at.

Creams (Medicinal, Cosmetic)

Creams are typically for personal use by consumers for cosmetic and surface medical treatments. Physical properties and chemistry can vary greatly depending on the cream base and added substituents. Some creams will be petroleum based like Petroleum Grease, while others may be emulsions suspended in water. They typically are shear-thinning mixtures.

Greases

Commonly referred to as lubricating, automotive, or bearing grease. Generally mixtures of a mineral oil with one or more metallic soaps; the most common are those of sodium, calcium, barium, aluminum, lead, lithium, potassium and zinc. The texture of grease may be smooth, buttery, ropy, fibrous, spongy or rubbery and have a variety of viscosities.
