Abstract

The invention relates to a vegetable paper comprising bast fibres, characterized in that the amount of bast fibres is at least 40% by weight of dry matter of the vegetable paper, and the bast fibres have a length-weighted average length of from 1 mm to 12 mm, and cosmetic products comprising the vegetable paper.

Claims (26)

1. A vegetable paper comprising a mixture of bast fibres and cellulose fibres, wherein

the amount of bast fibres is at least 40% by weight of dry matter of the vegetable paper,

the amount of cellulose fibres is at least 10% by weight of dry matter of the vegetable paper, and

the bast fibres have a length-weighted average length of from 1 mm to 12 mm, the mixture of bast fibres and cellulose fibres has a degree of refinement from 5° SR to 50° SR, wherein ° SR stands for Schopper-Riegler, and wherein the basis weight of the vegetable paper is from 15 g/m 2 to 70 g/m 2 .

2. The vegetable paper according to claim 1 , wherein the bast fibres are selected from hemp fibre, Indian hemp fibre, jute fibre, kenaf fibre, kudzu fibre, Dalbergia ecastaphyllum fibre, flax fibre, okra fibre, nettle fibre, papyrus fibre, ramie fibre, sisal fibre, esparto fibre, and mixtures thereof.

3. The vegetable paper according to claim 1 , wherein the bast fibres have undergone extraction in a solvent.

4. The vegetable paper according to claim 1 , wherein the cellulose fibres are selected from wood pulp, lyocell fibres, viscose fibres, cellulose acetate fibres, and mixtures thereof.

5. The vegetable paper according to claim 4 , wherein the amount of lyocell fibres is from 10% to 40% by weight of dry matter of the vegetable paper.

6. The vegetable paper according to claim 4 , wherein the amount of wood pulp is from 10% to 40% by weight of dry matter of the vegetable paper.

7. The vegetable paper according to claim 1 further comprising an additive selected from a wet strength agent, a dry strength agent, a softening agent, a lotion composition, a wetting agent, latex, a cannabinoid, and mixtures thereof.

8. The vegetable paper according to claim 7 wherein the additive is a cannabinoid.

9. The vegetable paper according to claim 7 , wherein the amount of additive is less than 3% by weight of dry matter of the vegetable paper.

10. A hybrid paper comprising the vegetable paper as defined in claim 1 and a second paper, said second paper being a spunbound support or being manufactured via a wet laid process, a drylaid carded process using long artificial fibres, long natural fibres, cellulose fibres, and mixtures thereof, or an airlaid process using long artificial fibres, long natural fibres, cellulose fibres, and mixtures thereof.

11. A cosmetic product comprising the vegetable paper as defined in claim 1 .

12. The cosmetic product according to claim 11 wherein the cosmetic product is a cosmetic mask, an eye patch, a body envelope, or a wipe.

13. The cosmetic product according to claim 11 further comprising an active principle chosen from sebum regulators, antimicrobial agents, antibacterial agents, matt-effect agents, astringents, acidifying agents, cicatrizing agents, exfoliants or kerato-regulating agents, occlusive agents, protective agents, disinfectants, emollients, nourishing agents, moisturizers, anti-ageing agents, calmatives, decongestants or veinotonic agents, occlusive agents, UV-screening agents, humectants, hygroscopic agents, gelling agents, exfoliants, anti-free radical, cell-regenerating or cell-stimulating agents, firming agents, tautening agents, anti-glycation agents, lightening agents, and mixtures thereof.

14. A wipe comprising the vegetable paper as defined in claim 1 .

15. A hygiene paper comprising the vegetable paper as defined in claim 1 .

16. An absorbent paper comprising the vegetable paper as defined in claim 1 .

17. A process for manufacturing a vegetable paper as defined in claim 1 via a wet route.

18. The process according to claim 17 comprising the following steps:

a) mixing bast fibres with a solvent to extract all or some of the bast fibre compounds that are soluble in the solvent,

b) separating of the bast fibres from the soluble compounds to obtain the bast fibres which have undergone extraction in a solvent,

c) forming the vegetable paper via a wet process using the bast fibres which have undergone extraction in a solvent.

19. Process according to claim 17 , wherein the vegetable paper undergoes an additional hydroentanglement treatment.

20. The vegetable paper according to claim 1 , wherein the amount of cellulose fibres is at least 20% by weight of dry matter of the vegetable paper.
