The present disclosure describes acyl halide liquid dispersions and tunable methods of treating cellulosic materials with compositions that provide increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for reacting acyl halides with and binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

Provided is a paper treatment agent with which improved touch feeling different from smoothness that has been conventionally studied is obtainable when a pressure is applied like nose blowing or the like. A paper treatment agent of the present invention is a paper treatment agent containing (A) a polyhydric alcohol as a main component, the paper treatment agent contains (B) a sucrose fatty acid ester having an acyl group with more than 12 and less than 22 carbon atoms and an HLB of 11 or more and (C) an ionic surfactant, and it is characterized in that a mass ratio (C/B) of the component (C) to the component (B) is 0.65 to 24. According to the paper treatment agent of the present invention, when a pressure is applied to treated paper like nose blowing or the like, slick texture that is specific and distinctive smoothness which is non-conventional is obtainable.

The present invention relates to a process for preparing a surface treated calcium carbonate-comprising material, a surface treated calcium carbonate-comprising material obtained by the process, an article comprising the surface treated calcium carbonate-comprising material, a polymer composition and the use of the surface treated calcium carbonate-comprising material in polymer applications.

The present invention relates to thermal insulation materials, particularly to environmentally friendly thermal insulation materials, manufacturing of which involves recycled raw materials and hemp fibres. The thermal insulation material described in the invention further comprises bi-component binder and conservation additive.

A method of making an absorbent structure including forming a stock mixture of fibers, a cationic wet strength resin, an anionic polyacrylamide and a cellulase enzyme, and at least partially drying the stock mixture to form a web.

The invention concerns a wrapper paper which is suitable for use on aerosol-generating articles and which comprises pulp fibers and a char-former, wherein the pulp fibers make up at least 70% and at most 95% of the mass of the wrapper paper and the char-former is contained in a concentration of at least 5% and at most 20% with respect to the mass of the wrapper paper and is present in a concentration in the wrapper paper such that the quotient r=R.sub.T/R.sub.o of the tensile strength R.sub.o, measured in accordance with ISO 1924-2:2008 under the conditions of ISO 187:1990, and of the tensile strength R.sub.T, measured in accordance with ISO 1924-2:2008 under the conditions of ISO 187:1990 after the wrapper paper has been exposed to a temperature of 230° C. for one minute, is at least 0.20 and at most 0.90.

The present invention relates to an enhanced process for the production of cellulose pulps with increased quality and applicability of said pulps, especially their physical resistance properties and degree of resistance to drainage, through an enzymatic treatment step comprised in the production process of said cellulose pulp, concomitantly with the polymer dosage based on carbohydrates.

Glycine is an organic compound that can be used in the making of a synthetic base that obviates all the drawbacks of strong bases such as sodium hydroxide. The new compound is made by dissolving glycine in water and adding calcium hydroxide at a molar ration of about 1:1. Next, sodium percarbonate is dissolved in the solution to produce the new compound, which can be referred to as glycine hydroxide.
