A hair-coloring predictive test system and method allowing the pre-application testing of one or more hair dyes by applying the dye to a striated color-base blotter formulated and colored to correspond to a client's hair, either before or after optional lightening, resulting in an example swatch showing the highlights, mid-tones, and shadow tones that will be seen in the corresponding real hair.

A composition is provided comprising a) cellulose fibres having a number average length of from 0.001 to 0.5 mm and a specific surface area of from 1 to 100 m.sup.2/g; b) an at least partially hydrolysed vinyl acetate polymer; and c) at least one anionic polymer. The composition is useful in providing self-supporting films or coating layers for providing barriers to permeable substrates.

This specification discloses suspensions and method for making the suspensions. The suspension comprises a suspension medium and is loaded with an insoluble solid. The suspension medium is an aqueous solution made at least one soluble polymer and at least one thixotropic gum. The suspension medium can be loaded with high levels of solids (more than 15% by weight of the medium). The resulting suspension is highly stable and has low viscosity. In embodiments the suspension exhibits no significant sedimentation for at least 3 months, and has a viscosity of less than about 20,000 cP. In an illustrative embodiment, the suspensions may be used to improve the properties of corrugating adhesives by adding to a corrugating adhesive a suspension that has suspension medium comprising polyvinyl alcohol and gellan and that suspends unmodified high amylose starch.
