CLEANSING COMPOSITION
FIELD OF THE INVENTION
The invention relates to cleansing compositions. In particular, the invention is concerned with very mild and high foaming cleansing compositions suitable for cleansing the skin and hair.
BACKGROUND TO THE INVENTION AND PRIOR ART
The most widely used anionic surfactants in cleansing compositions are alkyl sulphates, polyoxyethylene alkyl sulphates and alkyl benzene sulphonates. These compounds are known to have a good foaming and deterging power. Due to their harshness, however, they are not desirable as components for cleansing compositions topically applied to human skin and hair. Their damaging effect particularly where young, tender or damaged skin is involved, has been the subject of intense study for many years.
On the other hand milder surfactants often suffer from the draw-back that they do not provide high foam which is very important for the consumer. Therefore, there is a strong need for products which are not only very mild but also possess an excellent foaming power.
US-A-3,728,447 (C J Patterson) discloses hair shampoo compositions containing fatty acid lactylates or
glycolates. While the cleaning action of shampoos based on the fatty acid glycolates is satisfactory, the foam is minimal. In order to achieve higher foaming action it is described to include harsh detergents such as sodium lauryl sulphate or triethanolamine lauryl sulphate. When the glycolates are used in conjunction with such a booster, detergent the quantity of the glycolates present in the composition is reduced down to about 1 to 2% by weight.
Applicants in their search for mild cleansing compositions, in particular for cleansing human skin or hair, with the added attribute that full lather is produced, have unexpectedly discovered that a narrow range of acyl glycolates in combination with specific co- surfactants provide the desired effects when used in particular amounts. The compositions so obtained are capable of producing a superior lather and accordingly have great consumer appeal. Also, the compositions are so mild that they can safely be used for cleansing the skin and the hair and other more delicate skin areas.

Water
The cleansing composition according to the invention also comprises water. The water will normally be present in an amount of up to 85%, preferably from 10 to 85% by weight of the composition.
Optional Ingredients
The cleansing composition according to the invention can also comprise optional ingredients to modify the physical or chemical characteristics of the composition, eg. product form, foaming properties, pH-value or shelf life.
Examples for ingredients which can be included in the compositions according to the invention are:
Emollients, such as:
[PEG]-20 Corn Glycerides, [PEG]-60 Corn Glycerides, [PEG]-20 Almond Glycerides, - [PEG]-60 Almond Glycerides,
[PEG]-12 Palm Kernel Glycerides, [PEG]-45 Palm Kernel Glycerides, [PEG]-20 Evening Primrose Glycerides, [PEG]-60 Evening Primrose Glycerides, - Ethoxylated (EO)-20 methyl glucoside, also referred to as Methyl gluceth-20 Propoxylated (E0)-10 methyl glucoside.
A group of preferred emollients are poly (oxyalkylene) glycerides mono-substituted with a Cι0 to C18 alkyl group and having up to 20 C2 to C3 oxyalkylene moieties per molecule of the glyceride, as an average value.
Especially preferred emollients are Polyoxyalkylene methyl glucosides having, as an average value, up to 20 C2 - C3 oxyalkylene moieties per molecule glucoside. These emollients are very beneficial as they impart a soft feeling to the skin and support the ability of the skin to retain moisture. Examples for such Polyoxyalkylene methyl glucosides are available as Glucam E-20 and Glucam P10, respectively, from Amerchol.
Humectants, such as glycerine, sorbitol, sodium 2- pyrrolidone-5-carboxylate, soluble collagen, gelatine, ethoxylated (E0)-20 methyl glucoside, and propoxylated (E0)-10 methyl glucoside.
Preservatives, such as ethanol, benzoic acid, sodium benzoate, sorbic acid, alkali metal halides;
PH controlling agents, such as Sodium hydroxide,
Citric acid, Triethanolamine, Potassium hydroxide, Amino Sorbitol. The pH controlling agents are preferably present in an amount sufficient to adjust the composition to a pH value in the range of 5.5 to 8.5.
Propellants, such as fluorochloro hydrocarbons, propane, butane, isobutane, dimethyl ether, carbon dioxide, nitrous oxide;
Foam modifying agents, such as cationic polymers, especially quaternised ammonium hydroxy ethyl cellulose polymers, eg. available as polyquaternium-24 or polyquaternium-10. These polymers make the foam creamier and richer.
Further Optional Ingredients
The composition according to the invention can also contain other optional agents, that is ingredients other than the main ingredients already defined which are conventionally employed in cleansing compositions, such as thickeners.
USE OF THE COMPOSITION
The cleansing composition according to the invention is primarily intended as a personal washing product for cleansing the face. It can also be used for washing the hair as well as the whole body. The composition according to the invention is preferably used as facial cleanser, facial wash foam, hair shampoo, body shampoo, bath foam or shaving cream. Due to the high detergency provided by the composition it is also possible to use it in non-cosmetic applications, such as a household cleanser, carpet cleanser or detergent for tableware.
The following procedure is an example for the use of the cleansing composition according to the invention; a small quantity, for example from 1 to 5ml, of the composition is either rubbed between the hands, together with water together to form a foam which is then used for washing or applied via a sponge to the area to be cleansed, or the foam is generated directly on that area. The foam is subsequently rinsed away with clean water.
The cleansing composition according to the invention can take the form of a liquid or gel, intended to be dispensed from a capped container such as a bottle, roll-on applicator or tube, or a pump-operated or propellant-driven aerosol dispenser. The composition can also take the form of a solid, such as a stick or a bar or tablet intended to be used for washing instead of a conventional soap bar.
Foaming Properties of the Composition
Although the composition according to the invention does not include harsh surfactants, as are found in conventional cleansing compositions, its foaming power is excellent.
Foam-Height Test
The test-method which can be used to assess the foaming power of the cleansing compositions according to the invention is the ASTM D 1173-53 test, also referred to as Ross-Miles test, and described in J Ross and G D Miles, American Society for Testing Materials, 1953, pages 644- 646. The test is carried out at a temperature of 20°C by using an aqueous test solution of 0.3% by weight acyl glycolate and 0.1% by weight co-surfactant. This is a realistic concentration of the cleansing composition according to the invention when used by the consumer, eg. when topically applied on the face or body together with water to generate the desired foam. The pH value of the test solution has been adjusted to a pH of 7.5 by addition of aqueous sodium hydroxide solution.
The cleaning composition according to the invention conveniently has a foam height of more than 130mm, as measured by the foam height test carried out under the conditions described above.
Preferably the compositions according to the invention have a foam height of more than 150mm, more preferably more than 170mm and most preferably more than 190mm.
