The composition includes a combination of two critical ingredients, originating from two natural superfood products: olive and kale. This current technology utilizes the sprout of kale, instead of the whole plant, as one ingredient. In the perspective of olive extract, it is either in the form of a concentrated liquid syrup of olive tree and leaf, which is enriched with natural polyphenols, especially with high content of hydroxytyrosol, or in the form of pure liquid hydroxytyrosol. An enhanced antioxidant power is observed when incorporating the kale sprouts together with the olive leaf extract. ## Claims ### Claim 1 A composition consisting of: (i) olive tree/leaf extract; (ii) kale extract; (iii) water, diols, triols, polyols or combinations thereof; and (iv) a polysaccharide thickening agent. ### Claim 2 (depends on 1) The composition according to claim 1 wherein said kale extract is in the form of sprout powder; and wherein said olive tree/leaf extract is in the form of a liquid syrup, or in the form of hydroxytyrosol. ### Claim 3 (depends on 2) The composition according to claim 2 wherein said olive syrup is highly enriched with polyphenols. ### Claim 4 (depends on 3) The composition according to claim 3 wherein said polyphenols are hydroxytyrosol, tyrosol and oleuropein. ### Claim 5 (depends on 2) The composition according to claim 2 wherein said olive syrup contains at least 25% hydroxytyrosol. ### Claim 6 (depends on 2) The composition according to claim 2 wherein said hydroxytyrosol has a purity higher than 99.5%. ### Claim 7 (depends on 2) The composition according to claim 2 wherein said kale sprout powder enhances the antioxidant power of the olive leaf/tree extract in the form of the liquid syrup or the hydroxytyrosol. ### Claim 8 (depends on 2) The composition according to claim 2, wherein concentration range of the sprout powder is 0.1% to 5%. ### Claim 9 (depends on 1) The composition according to claim 1 wherein said water is deionized. ### Claim 10 (depends on 1) The composition according to claim 1 wherein said diols, triols and polyols are selected from ethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, hexylene glycol and glycerine. ### Claim 11 (depends on 1) The composition according to claim 1, wherein said composition provide cosmetic bases with antioxidant power. ### Claim 12 (depends on 11) The composition according to claim 11, wherein said antioxidant power is the same at room temperature. ### Claim 13 (depends on 11) The composition according to claim 11, wherein said antioxidant power does not change at elevated temperature and does not change over time. ### Claim 14 (depends on 1) The composition according to claim 1, wherein said composition shows higher antioxidant power than butylated hydroxytoluene (BHT). ### Claim 15 (depends on 1) The composition according to claim 1, wherein said composition can be used in a range of cosmetic products, in the form of a lotion, a cream, a gel, a spray, a foam, a solid stick, a shampoo, a hair conditioner, a lacquer, a make-up or a sunscreen. ### Claim 16 (depends on 1) The composition according to claim 1, wherein the concentration of sulforaphane from the kale extract ranges from 1 ppm to 8000 ppm. ### Claim 17 (depends on 1) The composition according to claim 1, wherein the polysaccharide thickening agent is xanthan gum.
