Dry mixture and personal care composition as well as methods for their production

A method to produce a dry mixture comprising a liquid and a fibrous material of natural origin obtained from plants, which fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates, wherein the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm, wherein the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm, and wherein the fibrous material contains more than 10 wt % xy lose referred to the total weight of the fibrous material, the method comprising at least the steps of

• a.) comminuting dry pulp by mechanical means;
• b.) dispersing said comminuted pulp in a liquid;
• c.) further comminuting the pulp dispersed in the liquid to form a mixture comprising the liquid and the fibrous material comprising micro-scaled and/or nano-scaled fibril agglomerates, wherein the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm, and wherein the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm;
• wherein the fibrous material contains more than 10 wt % xylose referred to the total weight of the fibrous material,
• and wherein the liquid is acetone, hexane, cyclohexane, Freon-11, dioxane, t-butyl methyl ether, dimethoxymethane, chloroform, dichloromethane, ethyl acetate, tetrahydrofuran, 2-butanone, 1,2-dimethoxyethane, acetonitrile, and mixture thereof, or a non-aqueous protic solvent, or an azeotropic mixture;
• and
• d) drying the mixture.

• wherein the fibrous material contains more than 10 wt % xylose referred to the total weight of the fibrous material, and wherein the liquid is a protic liquid selected from the group comprising water, ethanol, isopropanol, 1,2-propanediol, 1,3-propanediol, dipropylene glycol, glycerol, pentaerythritol (CAS:
• 115-77-5), and a mixture thereof;
• and
• d) drying the mixture.

A method to produce a personal care composition comprising the steps of:

• adding a polyol to a dry mixture under gentle agitation, the dry mixture comprising fibrous material of natural origin obtained from plants, which fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates, wherein the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm, wherein the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm, and wherein the fibrous material contains more than 10 wt % xylose referred to the total weight of the fibrous material;
• adding a preservative to the mixture of the preceding step under gentle agitation;
• adding a hydrophilic polymer(s) and/or the water-soluble or water-dispersible surfactant(s) under gentle agitation to the mixture of the preceding step until said polymer(s) and/or surfactant(s) are homogeneously dispersed in the mixture
• adding an oil(s) and/or other hydrophobic ingredients to the mixture of the preceding step and dispersing said oil(s) and/or hydrophobic ingredients by using dissolver or disperser, until a homogeneous pre-emulsion is obtained;
• adding demineralized water to the mixture of the preceding step under gentle agitation until the desired product consistency is obtained;
• adding a fragrance to any of the preceding mixtures.
