Abstract
Formulation for rinsing textile fiber articles in an aqueous or aqueous-alcoholic medium, comprising an active substance comprising a liquid or solid, hydrophobic organic or organosilicon material in particulate form, a surfactant and a vehicle comprising a water-soluble organic polymer, the vehicle being capable of bringing said active substance to the surface of said textile fiber articles in the rinsing operation.
Claims43
Formulation (F) intended for use in an operation of rinsing (R) textile fiber articles (S) by means of an aqueous or aqueous-alcoholic medium (MR), said formulation (F)
- comprising at least one active substance (A) comprising at least one solid or liquid organic or organosilicon material in particulate form and a vehicle (V) comprising at least one organic polymer, capable of taking said active substance (A) to the surface of said textile fiber articles (S) in the rinsing operation (R),
- in the form:
- of a stable dispersion, with a pH of from 2 to 5, of said active substance (A) in an aqueous or aqueous-alcoholic medium (MAV) comprising said vehicle (V), or
- in a solid form obtained by drying said dispersion,
- the nature of the active substance (A), of the aqueous or aqueous-alcoholic medium (MAV), and of the vehicle (V) being such that
- the active substance (A)
- is insoluble in the medium (MAV),
- has an overall zero or cationic charge in the medium (MAV),
- is stabilized in the medium (MAV) by means of a cationic surfactant (TAC), it being possible for said cationic surfactant (TAC) to be wholly or partly replaced by a nonionic surfactant when the material constituting the active substance (A) is intrinsically cationic or intrinsically potentially cationic in the medium (MAV),
- remains insoluble in the rinsing medium (MR);
- the vehicle (V)
- is soluble or dispersible in the medium (MAV) and in the rinsing medium (MR)
- has an overall cationic or zero ionic charge in the medium (MAV),
- at the pH of the rinsing operation in the rinsing medium (MR) is capable of developing anionic charges in sufficient quantity to destabilize the active substance (A) in the rinsing medium (MR).
Use in a formulation (F) intended for use in an operation of rinsing (R) textile fiber articles (S) by means of an aqueous or aqueous-alcoholic medium (MR), formulation (F) comprising at least one active substance (A) comprising at least one liquid or solid organic or organosilicon material in particulate form and being
- in the form of a stable dispersion with a pH of from 2 to 5 of said active substance (A) in an aqueous or aqueous-alcoholic medium (MAV) or
- in a solid form obtained by drying said dispersion,
- the nature of the active substance (A) and of the aqueous or aqueous-alcoholic medium (MAV) being such that the active substance (A)
- is insoluble in the medium (MAV)
- has an overall zero or cationic charge in the medium (MAV),
- is stabilized in the medium (MAV) by means of a cationic surfactant (TAC), it being possible for said cationic surfactant (TAC) to be wholly or partly replaced by a nonionic surfactant when the material constituting the active substance (A) is intrinsically cationic or intrinsically potentially cationic in the medium (MAV)
- remains insoluble in the rinsing medium (MR);
- of at least one organic polymer which
- is soluble or dispersible in the medium (MAV) and in the rinsing medium (MR)
- has an overall cationic or zero ionic charge in the medium (MAV)
- and is capable, at the pH of the rinsing operation in the rinsing medium (MR), of developing anionic charges in sufficient quantity to destabilize the active substance (A) in the rinsing medium (MR);
- as a vehicle (V) capable of bringing said active substance (A) toward the surface of said textile fiber articles (S) in the rinsing operation (R).
Process for enhancing the deposition of an active substance (A) comprising at least one solid or liquid organic or organosilicon material in particulate form on the surface of textile fiber articles (S), during an operation of rinsing of said articles by means of an aqueous or aqueous-alcoholic medium (MR) obtained from a formulation (F) comprising said active substance (A), the formulation (F) being
- in the form of a stable dispersion with a pH of from 2 to 5 of said active substance (A) in an aqueous or aqueous-alcoholic medium (MAV) or
- in a solid form obtained by drying said dispersion,
- the nature of the active substance (A) and of the aqueous or aqueous-alcoholic medium (MAV) being such that the active substance (A)
- is insoluble in the medium (MAV)
- has an overall zero or cationic charge in the medium (MAV),
- is stabilized in the medium (MAV) by means of a cationic surfactant (TAC), it being possible for said cationic surfactant (TAC) to be wholly or partly replaced by a nonionic surfactant when the material constituting the active substance (A) is intrinsically cationic or intrinsically potentially cationic in the medium (MAV)
- remains insoluble in the rinsing medium (MR);
- by adding to said formulation (F) a vehicle (V) comprising at least one organic polymer which
- is soluble or dispersible in the medium (MAV) and in the rinsing medium (MR)
- has an overall cationic or zero ionic charge in the medium (MAV)
- and is capable, at the pH of the rinsing operation in the rinsing medium (MR), of developing anionic charges in sufficient quantity to destabilize the active substance (A) in the rinsing medium (MR).
