Process for the manufacture of multicolor poured cosmetics
The invention relates to a process for preparing a multicoloured poured cosmetic product, particularly a process for obtaining a multicoloured lipstick, gloss or cosmetic product for the eye contour area, as well as the products obtained by means of this process.
1. A process for preparing a multicoloured poured cosmetic product, comprising the steps of:
a) arranging a first layer of cosmetic product by pouring a preset amount of a first melted coloured cosmetic product on a plane, within a square or rectangular containment perimeter;
after the layer of the preceding step has solidified, pouring directly over the solidified layer to spread out horizontally thereon a preset amount of a second cosmetic product of a different colour from the first one within the square or rectangular containment perimeter;
b′) optionally repeating step (b) one or more times in order to add layers of cosmetic products of different colours;
c) removing the containment perimeter, thereby obtaining a multicoloured or “dégradé”, multilayered block;
d) sectioning, according to cutting planes incident to the layers of coloured cosmetic products, the multicoloured or “dégradé” multilayered block in order to obtain multicoloured or “dégradé” sections of the same.
2. The process according to claim 1 , wherein said multicoloured poured cosmetic product is a lipstick, a gloss or a cosmetic for the eye contour area.
3. The process according to claim 1 , wherein said containment perimeter consists of a single hollow cylindrical structure of a sufficient height to contain all the layers of poured products.
4. The process according to claim 1 , wherein said containment perimeter consists of two or more hollow cylindrical elements, each having the same height as a layer of poured product to be sequentially superimposed upon steps (b) and (b′).
5. The process according to claim 1 , wherein said containment perimeter is square or rectangular.
6. The process according to claim 1 , said containment perimeter is made of metal, glass, plastic or silicone material.
7. The process according to claim 1 , wherein said poured layers of steps (a), (b) and (b′) have the same thickness.
8. The process according to claim 1 , wherein said poured layers of steps (a), (b) and (b′) have a different thickness.
9. The process according to claim 1 , wherein the multilayered block is sized either before or after the sectioning step (d).
10. The process according to claim 1 , wherein said multicoloured poured cosmetic product is inserted in a suitable bottom base and optionally further packaged.
11. The process according to claim 10 , wherein said multicoloured poured cosmetic product is subjected to pressing before being optionally packaged.
12. The process according to claim 1 , wherein signs, figures or marks are printed on said sectioned poured cosmetic product by means of pressing.
13. The process according to claim 1 , wherein the sections are further processed in order to engrave signs, figures or marks thereon, or obtain particular three-dimensional shapes.
