The present invention relates to a process for obtaining polysaccharides from jatoba seeds, comprising the steps of: a) seed processing (dry process); b) aqueous extraction at 1% to 5% of powder mass per volume, preferably 2% of powder mass per volume; c) precipitation with ethanol 969GL using 1 to 3 times the aqueous extract volume; d) press filtration of the precipitate obtained in (c); e) solublization of the polysaccharides obtained in step (d) with water; and f) drying the polysaccharides obtained in step (e). In another embodiment, the present invention relates to a cosmetic composition containing polysaccharides obtained according to the process defined above and to the use of said polysaccharides.

Process for obtaining polysaccharides from jatoba seeds, comprising the steps of: a) seed processing; b) aqueous extraction at 1% to 5% of powder mass per volume, preferably 2% of powder mass per volume; c) precipitation with ethanol 96° GL using 1 to 3 times the aqueous extract volume; d) press filtration of the precipitate obtained in (c); e) solublization of the polysaccharides obtained in step (d) with water; and f) drying the polysaccharides obtained in step (e). Claim: 2. The process, according to claim 1, characterized in that it further comprises a step of separating the polysaccharides after the step of aqueous extraction. Claim: 3. The process, according to claim 2, characterized in that the separation step is centrifugation. Claim: 4. The process, according to claim 3, characterized in that the centrifugation is performed at 4100 RPM for 15 minutes. Claim: 5. The process, according to claim 1, characterized in that the aqueous extraction step is carried out at a temperature of 70° C. for 4 hours. Claim: 6. The process according to any one of claims 1 to 5, characterized in that the dehydration of the supernatant is done by spray drying. Claim: 7. The process according to any one of claims 1 to 5, characterized in that the dehydration of the supernatant is done by freeze drying. Claim: 8. A cosmetic composition, characterized in that it comprises the polysaccharide obtained through the process as defined in any one of claims 1 to 7. Claim: 9. Use of polysaccharides from jatoba seeds obtained through a process as defined in any one of claims 1 to 7 characterized in that it is for the preparation of anti-wrinkles or anti-age cosmetic composition. Claim: 10. Use of polysaccharides from jatoba seeds obtained through a process as defined in any one of claims 1 to 7 characterized in that it is as a thickening agent in cosmetic compositions.
