1. An injection moulded polymeric household bottle cap made of a polypropylene composition comprising: about 10% particulate CaCO3 by total weight of the composition;from about 0% to about 6% additive by total weight of the composition; andpolypropylene; wherein the polypropylene composition in its solid form and with average wall thickness T has a flexural modulus being at least about 95% of the flexural modulus measured on a reference polypropylene composition substantially free of CaCO3 and having average wall thickness of at least about T+10%; and wherein the bottle cap has an average wall thickness from 0.5 mm to 10 mm; and wherein the polypropylene composition is recyclable. 2. A bottle cap, according to claim 1, wherein the polypropylene composition in its solid form has a compression stability of at least about 10% higher than compression stability of a reference polypropylene composition substantially free of CaCO3. 3. The bottle cap, according to claim 1, wherein the polypropylene composition is stable over a period of time of at least 6 months when exposed to a temperature from about 25 to about 45° C., a relative humidity from about 20% to about 60%, and exposure to light of about 2700 Kelvin to about 3300 Kelvin. 4. The bottle cap, according to claim 1, wherein said polypropylene composition comprises from about 0% to about 3% additive, by weight of the final composition. 5. The bottle cap, according to claim 1, wherein additive is selected from the group consisting of impact modifiers, dispersants, filler coatings, foaming agents, processing agents, lubricants, particles, dyes and colorants, UV filters, anti-static agents, and mixtures thereof. 6. The bottle cap, according to claim 1, wherein said cap is suitable for sealing a container comprising a household composition and for dispensing said household composition. 7. The bottle cap, according to claim 1, comprising a dispensing orifice, a receiving portion, and hinged sealing portion. 8. The bottle cap, according to claim 1, wherein the bottle cap has an average wall thickness T of at least about 10% lower than the average wall thickness of a reference polypropylene bottle cap substantially free of CaCO3. 9. The bottle cap, according to claim 1, wherein the bottle cap has an average wall thickness T is reduced by at least about 20% than the average wall thickness of a reference polypropylene bottle cap substantially free of CaCO3. 10. The bottle cap, according to claim 1, having an average wall thickness from about 0.5 mm to about 1.5 mm. 11. The bottle cap, according to claim 1, said particulate CaCO3 has a particle size of about 2 to about 4 μm. 12. The bottle cap, according to claim 1, wherein the polypropylene composition comprises microspheres and/or foaming agents. 13. Packaging for a household product comprising: a container suitable for containing a household composition;an injection moulded polymeric household bottle cap according to claim 1, mounted onto said container and being suitable for sealing said container and for dispensing said household composition. 14. A household product comprising: a container;a household composition, contained in said container;an injection moulded polymeric household bottle cap according to claim 1, mounted onto said container. 15. The household product, according to claim 14, wherein said household composition is selected from the group consisting of personal care compositions, cleansing compositions, fabric care compositions, homecare compositions, and combinations thereof. 16. A household product, according to claim 15, wherein said household composition is a hair care composition comprising a component selected from the group of hair conditioning agents, hair styling agents, perming and waving agents, hair cleansing agents, hair colouring, dying or bleaching agents, hair shine or gloss imparting agents, and mixtures thereof.
