USE OF ALIPHATIC FATTY ALCOHOL IN DETERGENT FOAMING COMPOSITIONS FOR THE MAINTENANCE OF HARD OR TEXTILE SURFACES

The present invention relates to the use, in a foaming detergent composition for the maintenance of hard or textile surfaces, of an aliphatic fatty alcohol; the presence of an aliphatic fatty alcohol makes it possible to improve the appearance of the foam formed under the usual conditions of use of said composition.

It is known to produce stable foams from a concentrated aqueous composition comprising a foaming anionic surfactant (optionally ethoxylated fatty alcohol sulphates, fatty alcohol sarcosinates, alkanolamide sulphosuccinates, long alpha-olefin sulphonates). chain, long chain alkylbenzenesulfonates), a C 12 -C 16 alkanol, optionally a solvent (isopropyl alcohol, butoxyethanol, etc.) and optionally a polymer (polyacrylic acids, ethylene oxide-propylene oxide block copolymers, polyethylene glycols) biopolymers); the stable foams obtained have multiple uses, namely as a ground marker for agricultural surfaces during a phytosanitary treatment, as an insulator in safety systems, in drilling fluids, as an aid for extinguishing forest fires, in particular (US 4,050,944; US 4,442,018; US 4,770,794; US 6,369,122; US 6,376,566).

The consumer, during cleaning or maintenance operations that he performs or that are carried out in his presence, using a foaming detergent composition, is very sensitive to the abundance and the appearance of the formed foam , in particular the opacity or the whiteness thereof, which are indices of performance of the detergent medium.

The object of the invention is to obtain under the normal conditions of use of a detergent formulation for the maintenance of surfaces, especially for the cleaning of household or institutional hard or textile surfaces, the hand washing of the dishes , hand washing or semi-automatic washing or cleaning of car bodies, a stable foam with improved appearance. It is in particular to obtain a foam having a better aesthetic, especially in terms of its whiteness, and a creamy appearance. These benefits are translated to the consumer by an impression of cleanliness, as well as care of the treated surface. When it comes to a wash at the hand, this impression is also manifested in the hands of the manipulator.

The amount of surfactant (S), expressed in seconds, can represent from 0.1 to 99%, preferably from 0.5 to 60% of the total weight of detergent composition that can foam.

When the detergent composition is a soap-bar type solid, the amount of surfactant (S), expressed in dry matter, may represent up to 99%, preferably up to 95% of the total mass of detergent composition capable of to foam; this amount usually represents at least 50% of the total weight of foamable detergent composition. The soap bar solids may further contain water and / or a water-compatible solvent in an amount of up to 20% of the mass of said solid. By total mass of detergent composition is meant the mass of the whole composition including, beside the surfactant (S) and the aliphatic alcohol (AA), the other possible constituents (water, solvents, other additives). .)

30 ml of this solution are introduced into a graduated cylinder of 100 ml (length 250 mm / internal diameter 28 mm); the closed cylinder is returned 20 times manually. A foam is obtained. Image Analysis Then, at regular intervals (for example every ten minutes), digital photographs are taken in front of a black background of the foam thus generated; the photographs are then transformed into 256 levels of gray (gray scale from 0 to 255, 0 corresponding to black and 255 to white). We count the number of pixels corresponding to each level of gray. This gives a histogram whose average value is between 0 and 255.

The average value obtained for an empty cylinder in front of the same black background is subtracted from the value obtained for a foam, so as to obtain a value of 0 in the absence of foam. This value is normalized to 100 using a freshly generated reference foam (zero time) with an aqueous solution of aliphatic alcohol (AA) -free detergent composition, the amount of aliphatic alcohol-free detergent composition (AA). ) being such that the concentration of said aqueous solution of surfactant (S) is 0.5 g / liter of aqueous solution. A "whiteness" value of between 0 and 100 is thus obtained as a function of the evolution of the appearance of the reference foam over time. Evaluation

The foam corresponding to the detergent composition to be tested is generated and analyzed as above (cylinder returned 20 times, digital photographs at regular intervals and obtaining a histogram).

A value greater than 100 can be obtained if a tested foam is whiter than the reference foam.

Under the conditions of this test, a "whiteness" value of less than 60 is considered to be degraded (the foam becomes gradually transparent).

The following examples are given for illustrative purposes. Method for evaluating the whiteness of a foam

calibration

An aqueous reference solution comprising 0.5 g / l of sodium lauryl ether sulphate is prepared.

30 ml of this solution are introduced into a graduated cylinder of 100 ml

(length 250mm / inner diameter 28mm); the closed cylinder is returned 20 times manually.

Digital photographs are then made at regular intervals in front of a black background of the foam thus generated (reference foam); the photographs are then transformed into 256 gray levels (gray scale from 0 to 255).

We count the number of pixels corresponding to each level of gray. This gives a histogram whose average value is between 0 and 255.

The average value obtained for an empty cylinder in front of the same black background is subtracted from the value obtained for a foam, so as to obtain a value of 0 in the absence of foam.

This value is normalized to 100 for the freshly generated reference foam (time zero).

A "whiteness" value of between 0 and 100 is thus obtained as a function of the evolution of the appearance of the reference foam over time.

Evaluation

The foam corresponding to the detergent composition to be tested is generated and analyzed as above (cylinder returned 20 times, digital photographs at regular intervals and obtaining a histogram)

A value greater than 100 can be obtained if a tested foam is whiter than the reference foam. Under the conditions of this test, a "whiteness" value of less than 60 is considered to be degraded (the foam becomes gradually transparent).

The whiteness of the foam is degraded after 30-40 minutes.

Example 2: whiteness of a foam generated according to the invention.

An aqueous solution comprising 0.5 g / l of sodium lauryl ether sulphate is prepared.

30 ml of this solution are introduced into a graduated cylinder of 100 ml; the closed cylinder is returned 20 times manually.

The evolution of the whiteness of the foam generated as a function of time is given in the following table:
