Abstract: By the use of a known bacterial .alpha.-amylase having significant activity at pH values above 8.5 and temperatures below 30.degree. C., de-sizing and reactive dyeing by the cold dwell process may be carried out simultaneously on cellulose textile materials. The dyed materials have good color yield and levelness and are not hardened.
Abstract: This invention has for its object new cosmetic compositions for treating hair and skin containing a powder of plant origin obtained from extraction residues of various plants.

Abstract: Improved sulfonated lignin surfactants are provided for use as dispersants in dyestuffs. The process for providing the improved surfactants relates to using metals and borate salts to react with the azo dye reducing dihydroxy functions of the lignin molecule through chelation and ester formation mechanisms thereby inhibiting the lignin's azo dye reducing characteristics.
Abstract: A method of printing using polysaccharide gum S-88 as a thickening agent for printing pastes has been developed. The S-88 gum is gellable in the presence of about above 6% to 50% electrolyte. The gelling characteristic of the gum is useful in both single- and multi-phase print systems. The single-phase print system uses a print paste composition containing the S-88 gum together with about 1-6% concentration of electrolyte which, when applied to a substrate, and when the overall moisture content drop (by such methods as heating, etc.) results in a concomitant increase in electrolyte concentration sufficient to cause gelation. The multi-phase print system uses the electrolyte in one phase and the gellable gum in another; i.e., the electrolyte-containing paste or solution with concentration of 6-50% electrolyte is either impregnated on or in the substrate or is present in the printing paste which is applied before or after the S-88 gum-containing paste.
Abstract: Deacetylated Polysaccharide S-60, prepared by deacetylating the polysaccharide S-60 produced by fermentation of Pseudomonas elodea, ATCC 31461, has valuable properties in both the clarified and non-clarified form, and is useful as an agar substitute or a shapeable room deodorant.The non-clarified deacetylated gum contains about 17% protein and principally carbohydrate, which comprises glucuronic acid (.about.13% based on wt. gum) and the neutral sugars rhamnose and glucose in the approximate molar ratio 3:2.The clarified, deacetylated gum contains mostly carbohydrate and no more than about 2% protein.

Abstract: A novel polysaccharide S-60 is disclosed composed of principally carbohydrate, 10-15% protein, and 3-4.5% acetyl groups as the O-glycosidically linked ester. The carbohydrate portion contains about 11% glucuronic acid (based on wt. gum) and the neutral sugars rhamnose and glucose, the latter having an approximate molar ratio of 3 to 2. This polysaccharide is produced by a new Pseudomonas species, P. elodea, in a suitable fermentation medium.
Abstract: Aqueous dye preparations having a migration-regulating action and containing at least one dye insoluble in water, a dispersing agent and at least one further additive, which preparations are characterized in that they contain at least one water-soluble polymerization product containing carboxyl groups.
Abstract: Described is a process for the production of negligibly dusty preparations by spray drying an aqueous suspension containing at least one water-soluble dye or optical brightener and optionally further additives, characterized in that a dust-binding surface active agent is added to the aqueous suspension containing at least one adhesive as e.g. sorbitol and/or to the spray-dried product.

Abstract: Cationic or certain anionic dyes are rendered compatible with normally incompatible anionic and nonanionic polymers by the addition of certain surface active agents.
Abstract: Novel blends of algin and TKP are disclosed. The blends are useful in commercial gum applications where thickening, suspending, emulsifying, stabilizing, film-forming, and gel-forming properties are needed. They are particularly useful in the paper and textile industries.
