摘要:
The present invention relates to a process for improving the waterproofing of hides, skins, leathers, and furs, as well as other fibrous materials, by treatment with special surfactants in the beamhouse and/or in the treatment of the wet blues, prior to waterproofing. Particularly suitable as surfactants are anionic surfactants based on salts of N-acyl-amino acids and nonionic surfactants, such as alkyl polyglycosides or polyethyleneglycol carboxyalkyl ethers. The surfactants are used in amounts of 0.5 to 5% wt., relative to the pelt or shaved weight.

Chemical softening compositions are provided comprising a mixture of a quaternary ammonium compound and a polyhydroxy compound. Preferred quaternary ammonium compounds include dialkyldimethylammonium salts such as di(hydrogenated) tallow dimethyl ammonium chloride and di(hydrogenated) tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, and polyethylene glycols and polypropylene glycols having a weight average molecular weight from about 200 to 4000.The chemical softening compositions are prepared by first mixing the polyhydroxy compound into the quaternary ammonium compound at a specific temperature range wherein the polyhydroxy compound is miscible with the quaternary ammonium compound and then diluting the mixture with water at an elevated temperature to form an aqueous vesicle dispersion suitable for treating fibrous cellulosic material. The chemical softening compositions disclosed herein are primarily intended for softening disposable paper products such as tissues and towels. However, the chemical softening compositions can also be used to soften fibrous cellulosic materials in textile form.

Dentifrice containing, in combination, (A) a poly(hydroxypropyl ether) nonionic surfactant and (B) a salt of a specific derivative of a protein degradation product, selected from the group consisting of (i) an alkali metal salt of an N-acyl-N-methylglycine (N-acylsarcosine) of formula: ##STR1## where R denotes an alkyl or a mixture of alkyls containing from 9 to 17 carbon atoms, and (ii) an alkali metal salt of a condensate of C.sub.12 -C.sub.18 fatty acids with a hydrolyzed animal protein.This dentifrice is characterized by good foamability and pleasant taste and does not attack the buccal mucosae and the gums.
摘要:
Aqueous systems also are described which comprise at least about 40% of water and an N-acrylated amino hydrocarbyl sulfonic acid or salt composition characterized by the presence within the structure of an imido group or at least one acyl acyloxy or acylimidoyl group attached to the amino nitrogen, said groups being derived from the carboxylic acid groups contained in(a) maleic acid or anhydride, or(b) a hydrocarbyl-substituted polycarboxylic acid or anhydride.The amino hydrocarbyl sulfonic acid or salt compositions are useful as emulsifiers, thickeners, dispersants, etc. in the aqueous systems.
摘要:
Aqueous surfactant mixtures comprising a first amphoteric surfactant and at least one non-ionic surfactant and/or at least one amphoteric surfactant non-homologous with the first amphoteric surfactant, are obtained at a concentration substantially higher than previously obtainable by preparing them in the presence of sufficient water to form a "G" phase.
摘要:
A new surface-active agent of the formula: ##STR1## wherein R and R' are hydrocarbon groups, M being a cation it is particularly suitable for the production of micro-emulsions in the presence of aqueous saline solutions.One important application thereof is in the assisted recovery of crude oil.
摘要:
Emulsifier composition which comprises a condensation product of a fatty acid and a basic amino acid, and at least one secondary compound selected from the group consisting of a sterol compound, a fatty acid ester of polyhydric alcohol, a diol compound having hydroxyl groups at .alpha. and .beta. positions, a glycerophosphoric acid ester and a higher alcohol. Various creams and lotions can readily be prepared using the emulsifier composition.
摘要:
Detergent bars and liquids/pastes for topical application are given moisturizing properties by the use of materials selected from dicarboxylic acids and their salts, hydroxy acids and their salts and amino acids and their salts. Examples are adipic acid, maleic acid and glycine; in the bars these moisturizing components are usually present at a level of above 20%.
