Abstract
The present invention relates to the field of tablets for household and fabric care, in particular detergent tablets. The invention relates in particular to a tablet coated with an environmentally friendly solution based on a mixture of polymers of natural origin, which makes it possible to prevent the tablets from breaking or flaking during production, transportation and use thereof.
Claims18
A coated tablet for household and fabric care comprising a body formed from compacted powder, said body being coated with a water-soluble covering comprising:
- a) a biosourced film-forming agent composed of a mixture of a polysaccharide and at least one protein, said protein being chosen from animal proteins, plant proteins and the mixtures thereof, the proportion by mass of proteins in said film-forming agent being greater than or equal to 1% and less than 50%;
- b) optionally a humectant;
- c) water;
- wherein the ratio by mass (biosourced film-forming agent/humectant) is between 1 and 30 when the humectant is present.
A method for producing a coated tablet for household and fabric care comprising a body coated with a water-soluble covering, said method comprising the following steps:
- (1) providing a body formed from compacted powder;
- (2) spraying the surface of the body with a solution comprising:
- a) from 2% by mass to 80% by mass of a biosourced film-forming agent composed of a mixture of a polysaccharide and at least one protein, relative to the total mass of the solution, said protein being chosen from animal proteins, plant proteins and the mixtures thereof, the proportion by mass of proteins in said biosourced film-forming agent being greater than or equal to 1% and less than 50%;
- b) at least 20% by mass of water relative to the total mass of the solution;
- and
- c) optionally, a humectant;
- the ratio by mass (biosourced film-forming agent/humectant) in said solution being between 1 and 30 when the humectant is present.
