Definitions
- the present invention relates to an emulsion (E), in the form of a multiple emulsion (Em), the reverse internal emulsion of which comprises a hydrophobic active substance, or in the form of an emulsion (E).
- This emulsion can be used to convey said hydrophobic active material to a substrate in an aqueous medium.
- a detergent or rinsing composition or as a detergent or rinsing composition for washing or rinsing articles of textile fibers, with the aim of conveying and promoting the deposition of a hydrophobic active material such as a perfume, an agent hydrophobic care ..., on a textile article, in cotton in particular.
- a hydrophobic active material such as a perfume, an agent hydrophobic care ...
- W / OW water-in-oil-in-water
- EP-930 933-A- claims a process for the controlled release of an active principle contained in a multiple emulsion of water-in-oil-in-water type, characterized in that: - said multiple emulsion comprises a reverse emulsion Ei with an aqueous phase A1 which contains at least one hydrophilic active principle, said emulsion Ei being dispersed in the form of droplets of direct emulsion Ed, in an aqueous continuous phase A2, with the two emulsions Ed and Ei stabilized by at least one surfactant, present at level of their respective continuous phases and in that said multiple emulsion is brought into contact with a sufficient amount of an agent, so as to transform it into a direct emulsion and to induce the release of the active principle, contained in the aqueous phase A1 of the emulsion Ei, in the aqueous phase A2.
- the surfactant present in the aqueous continuous phase A2 of the Ed emulsion is preferably chosen from water-soluble lecithins, sucrose esters, esters of fatty acids, polyoxyethylenated alkylamides, triglyceride sulfates, alkyl sulfates, alkyl ether sulfates, alkyls sulfonates, alkylamine salts, fatty amines, lipoamino acids, alkylbetaines, alkylpolyglycol ethers, copolymers of alkylene oxides, modified polyesters, silicone polymeric surfactants.
- the surfactant present in the continuous phase of the Ei emulsion is preferably chosen from liposoluble lecithins, esters of sorbitan and of fatty acids, polyalkylene dipolyhydroxystearates, fatty acids, monoglycerides, polyglycerol esters, polyglycerol polyricinoleate, lactic and tartaric acid esters.
- the continuous phase of the Ei emulsion is an oily phase composed of at least one oil chosen from mineral, vegetable or animal oils.
- the direct emulsion Ed preferably comprises by volume from 50 to 99% of an aqueous continuous phase A2 for i to 50% of reverse emulsion Ei
- the reverse emulsion Ei is preferably composed by volume of 50 to 99% d '' a continuous phase for 1 to 50% of aqueous phase A1.
- W / O / W oil in water
- the reverse emulsion comprising an internal aqueous phase, comprising at least one hydrophilic active material, dispersed in an internal oily phase, said internal oily phase comprising at least one nonionic or cationic surfactant and / or at least nonionic amphiphilic polymer or cationic,

- Arlatone® F 127G of formula HO (CH 2 CH2 ⁇ ) ⁇ (CH (CH3) CH 2 ⁇ ) y (CH 2 CH 2 O) z H marketed by ICI -Uniquema
- Example 1 Multiple emulsion Composition of the inverse emulsion (Ei):
- Preparation of the internal aqueous phase Water is introduced into a 1 I reactor fitted with a paddle-type stirring.
- the Meyprogat® 7 powder is then gradually introduced with stirring at room temperature.
- the mixture is stirred for two hours at ambient temperature so as to disperse the gel particles of Meyprogat® 7 in a homogeneous manner.
- the dispersion is sheared using a rotor-stator type tool
- the pH of the internal aqueous solution / dispersion is 5 to 7.5
- the internal aqueous phase is then introduced over 45 minutes at room temperature. Stirring is continued for 15 minutes to refine the emulsion.
- An inverse emulsion (Ei) is obtained, the drops of dispersed aqueous phase (Wi) having a particle size of 1 ⁇ m (observation made under optical microscopy on a sample without and with prior dilution in Extrasoft oil).
- composition of the multiple emulsion
- a concentrated multiple emulsion (Em) is obtained, which is in the form of a viscous non-pourable cream; the average droplet size (d50) of internal reverse emulsion is close to 10 ⁇ m, with a low polydispersity index.
- Example 2 multiple emulsion A multiple emulsion is prepared according to the procedure of Example 1, replacing the 10 parts by weight of Meyprogat® 7 with 10 parts of cellulose monoacetate.
- EXAMPLE 3 Depositing Rhodorsil® Extrasoft Oil on Detergent Bath on Cotton
- Test is carried out in a Tergotometer laboratory apparatus, well known to formulators of detergent compositions.
- the device simulates the mechanical and thermal effects of washing machines of the American type with pulsator; thanks to the presence of 6 washing pots, it makes it possible to carry out series of simultaneous tests with appreciable time savings.
- the pots are heated to 40 ° C.
- Example 1 A quantity of double emulsion prepared in Example 1 or in Example 2 corresponding to 0.5 g of Rhodorsil® Extrasoft oil is introduced into each pot.
- Rinsing cycle The tissue squares are then rinsed 3 times for 5 minutes (each time) with cold water.
- the fabric squares are taken out and allowed to air dry. An assessment of softness performance is given by a jury of trained experts, in a blind test.
