Cosmetic compositions comprising at least one starch and at least one peg fatty diester, and uses thereof

A process for treating and/or caring for keratin fibers comprising

• applying to the fibers a cosmetic composition comprising, in a cosmetically acceptable medium:
• from 0.1% to 2% by weight, relative to the total weight of the composition, of at least one starch, and
• from 0.1% to 1% by weight, relative to the total weight of the composition, of at least one diester of a carboxylic acid and of polyethylene glycol
• having the following formula:
• R1—CO(O—CH2—CH2)n-OOCR2 (I)
• wherein:
• R1 is chosen from linear or branched, saturated or unsaturated alkyl or alkenyl groups comprising 8 to 30 carbon atoms,
• R2 is chosen from linear or branched, saturated or unsaturated alkyl groups comprising 8 to 30 carbon atoms,
• n is an integer ranging from 80 to 350.

A cosmetic composition, in a cosmetically acceptable medium, comprising:

• from 0.1% to 2% by weight, relative to the total weight of the composition, of at least one amphoteric starch chosen from monostarch phosphates, distarch phosphates and tristarch phosphates, and mixtures thereof, and
• from 0.1% to 1% by weight, relative to the total weight of the composition, of at least one diester of a carboxylic acid and of polyethylene glycol
• having the following formula:
• R1—CO(O—CH2—CH2)n-OOCR2 (I)
• wherein:
• R1 is chosen from linear or branched, saturated or unsaturated alkyl or alkenyl groups comprising 8 to 30 carbon atoms,
• R2 is chosen from linear or branched, saturated or unsaturated alkyl groups comprising 8 to 30 carbon atoms, and
• n is an integer ranging from 80 to 350.
