Emulsion-type cosmetic composition for coating keratin fibres, comprising: - an aqueous phase, - particles comprising at least one hard wax present in the form of at least one aqueous dispersion of particles of hard wax(es) having a melting point ranging from 65 to 120°C, the hard wax(es) being present at a total content greater than or equal to 10% by weight relative to the total weight of the composition, and - at least one emulsifying system capable of dispersing at least the hard wax(es), comprising: * at least one non-ionic surfactant with an HLB value at 25°C less than 8, and * at least one non-ionic surfactant with an HLB value at 25°C greater than or equal to 8, at least one among the non-ionic surfactant(s) with an HLB value at 25°C less than 8, and at least one among the non-ionic surfactant(s) with an HLB value at 25°C greater than or equal to 8, corresponding to the following formula: (ALK-[C] a - b) c -X in which formula: - ALK is a C 7 -C 23, preferably C 11 -C 21, more preferentially C 15 -C 17, alkyl group, - a and b are integers between 0 and 100, c is an integer between 1 and 100, in particular between 1 and 3, preferably equal to 1, a and b preferably being equal to 0, - X is a (poly)oxyalkylene group optionally substituted and/or ended with a hydroxyl group, X preferably being an oxyethylene group (CH 2 CH 2 O) n or (OCH 2 CH 2) n in which n is greater than or equal to 1, for example between 1 and 200, said (poly)oxyalkylene group preferably being a polyethylene glycol or being the result of at least one substitution of a hydroxyl group, preferably chosen from (poly)glycerols, the total content of hard wax(es) and optionally of additional wax(es) and the total content of emulsifying system are such that the weight ratio of the hard wax(es) plus the additional wax(es) to the emulsifying system is less than or equal to 1.75, peferably strictly less than 1.5, in particular between 1/3 and 1.25, the composition comprising a solids content greater than or equal to 42%, preferably greater than or equal to 45%, more preferentially greater than or equal to 48%, the non-ionic surfactant(s) with an HLB value at 25°C less than 8, and the non-ionic surfactant(s) with an HLB value at 25°C greater than or equal to 8, are present at a total content greater than or equal to 10% by weight relative to the total weight of the composition. - an aqueous phase, - particles comprising at least one hard wax present in the form of at least one aqueous dispersion of particles of hard wax(es) having a melting point ranging from 65 to 120°C, the hard wax(es) being present at a total content greater than or equal to 10% by weight relative to the total weight of the composition, and - at least one emulsifying system capable of dispersing at least the hard wax(es), comprising: * at least one non-ionic surfactant with an HLB value at 25°C less than 8, and * at least one non-ionic surfactant with an HLB value at 25°C greater than or equal to 8, * at least one non-ionic surfactant with an HLB value at 25°C less than 8, and * at least one non-ionic surfactant with an HLB value at 25°C greater than or equal to 8, - ALK is a C 7 -C 23, preferably C 11 -C 21, more preferentially C 15 -C 17, alkyl group, - a and b are integers between 0 and 100, c is an integer between 1 and 100, in particular between 1 and 3, preferably equal to 1, a and b preferably being equal to 0, - X is a (poly)oxyalkylene group optionally substituted and/or ended with a hydroxyl group, X preferably being an oxyethylene group (CH 2 CH 2 O) n or (OCH 2 CH 2) n in which n is greater than or equal to 1, for example between 1 and 200, said (poly)oxyalkylene group preferably being a polyethylene glycol or being the result of at least one substitution of a hydroxyl group, preferably chosen from (poly)glycerols, the total content of hard wax(es) and optionally of additional wax(es) and the total content of emulsifying system are such that the weight ratio of the hard wax(es) plus the additional wax(es) to the emulsifying system is less than or equal to 1.75, peferably strictly less than 1.5, in particular between 1/3 and 1.25, the composition comprising a solids content greater than or equal to 42%, preferably greater than or equal to 45%, more preferentially greater than or equal to 48%, the non-ionic surfactant(s) with an HLB value at 25°C less than 8, and the non-ionic surfactant(s) with an HLB value at 25°C greater than or equal to 8, are present at a total content greater than or equal to 10% by weight relative to the total weight of the composition.
