Description

A hair cleansing composition

Technical Field

The present invention belongs to the cosmetic field and relates to a hair cleansing composition comprising Di-PPG-2 Myreth-10 Adipate, at least one cationic conditioning polymer, at least one surfactant and water.

Background Art

A beautiful and attractive appearance is a desire for many people. Therefore, an essential part of the daily personal care of humans is focus on the hair of the head. Cleansing and shampoo products are commonly used to remove excess of soil or sebum from the hair. However, these products often leave the hair in a dry and rough condition. To address this issue many cleansing and shampoo products comprise components providing care to the hair and/or contain conditioning agents to provide a conditioning effect.

The purpose of the conditioning agents of the above products is not only to reduce the dryness and roughness of the hair. Moreover, the richness and slipperiness, as well as the gliding and combability of the hair are improved by the conditioning agents. Typically used conditioning agents are silicone containing compounds. However, these are well known for the fact that silicone residues can build up on the hair. As a result these silicone residues weigh down the hair, which reduces the hair volume. Therefore, it remains desirable to provide shampoo compositions free of silicone compounds. Such compositions are known in the state of the art, but compositions avoiding the incorporation of silicone compounds have drawbacks. After the application of such compounds the hair is described to be rough, dry, difficult to detangle and difficult to comb in the wet condition. In consequence compounds were included in shampoo compositions with the aim to replace the silicone components. The use of these silicone replacements has also been disclosed in prior art.

EP 2138155 A2 discloses silicone free hair conditioning compositions, which include PPG-3 benzyl ether myristate to reduce the weighing down of hair while providing a conditioning effect. EP 2138155 A2 does not disclose the use of Di-PPG-2 Myreth-10 Adipate.

EiS 2012/0014900 A1 describes compounds, which may be used to replace silicone compounds in hair compositions. Said components are near-terminal branched, exemplified by 14-methylhexadecyl stearate, 16-methyloctadecyl palmitate, and 12-methyltetradecylpalmitate. There is no disclosure of Di-PPG-2 Myreth-10 Adipate.

WO 2012/080224 A2 discloses non-silicone shampoo compositions comprising sclerogums, which are neutral polysaccharides. The use of Di-PPG-2 Myreth-10 Adipate is not disclosed.

WO 2013/074655 A1 describes the use of natural polymeric and non-polymeric esters as a silicone replacement. Such polymeric ester are produced by an esterification of one first dicarboxylic acid, one first monofunctional alcohol or monofunctional carboxylic acid and glycerin or derivatives thereof; the non-polymeric ester is produced by an esterification of one second dicarboxylic acid and one second mono functional alcohol. There is no disclosure of Di-PPG-2 Myreth-10 Adipate.

WO 2013/122861 A1 describes that traditional conditioning agents do not provide long-lasting benefits to keratin fibers upon washing with cleansing products like shampoos. The drawbacks are overcome by the incorporation of a hydrophobically modified cationic polymer, namely a hydrophobically modified poly(acrylamido-N-propyltrimethylammonium chloride) (polyAPTAC). The use of Di-PPG-2 Myreth-lO Adipate is not disclosed.

WO 2015/136568 Al discloses silicone-free products for hair, amongst others also hair shampoos, containing an oil or mixture of oils having a selected surface tension and an oil thickener; wherein the total composition has a viscosity of about 5,000cps or higher. There is no disclosure of Di-PPG-2 Myreth-lO Adipate.

WO 2016/023694 Al describes shampoo compositions, which are silicone-free. Said compositions contain an anionic surfactant in form of an alkyl sulfate surfactant, or ethoxylated alkyl sulfate, a fatty acyl isethionate, and a cationic polymer, said cationic polymer comprising cationic galactomannan and cationic cellulose. The use of Di-PPG-2 Myreth- lO Adipate is not disclosed.

A replacement of silicone in hair cleansing compositions should provide hair, especially human hair, with the benefits of suppleness, softness, and smoothness. The aim of the present invention was to develop a hair cleansing composition, which is silicone-free and contains components, which have a conditioning effect for the hair. Moreover, said components should provide the hair with care.

Still another need for cleansing compositions is the formation of foam. The foam should build up in a sufficient quantity and a creamy quality.

Summary of the Invention It has surprisingly been found out that a hair cleansing composition comprising Di-PPG-2 Myreth-lO Adipate provides hair with a conditioning effect illustrated by detangling and combing wet hair easily (Examples, Table 3).

In a first aspect, the present invention provides a hair cleansing composition comprising:

- Di-PPG-2 Myreth-lO Adipate,

- at least one cationic conditioning polymer,

- at least one surfactant, chosen from anionic, amphoteric and/or nonionic surfactants, and

- water.

The composition of the present invention is intended for an application to human hair.

Furthermore, the composition may optionally comprise the auxiliary components as listed in the part of“detailed description of the invention”, such as thickening agents, solvents, preservatives, anti-dandruff agents, perfumes, and/or pH adjusting agents.

As the composition according to the present invention is an aqueous preparation, water has to be present. In addition to Di-PPG-2 Myreth-lO Adipate, the at least one cationic conditioning polymer, and the at least one surfactant, chosen from anionic, amphoteric and/or nonionic surfactants, the composition comprises a balance amount of water, so that all the components amount to 100 % by weight. It is preferred that water is contained in an amount of 68 to 98 % by weight, more preferably of 70 to 95 % by weight, relative to the total weight of the composition. In another aspect, the composition according to the present invention is free from silicone components. The terms silicone component, silicone compound and silicone are used synonymously. The term“free from” is intended to mean a composition containing less than 0.1 % by weight, preferably less than 0.01 % by weight, more preferably 0.001 % by weight, most preferably 0 % by weight, of a respective compound, relative to the total weight of the composition.

In another aspect, the present invention refers to use of the composition of the present invention for providing hair with suppleness, softness, and smoothness. Furthermore, the invention also relates to the use of the composition according to the invention for providing hair which can be easily detangled and combed in a wet condition.

The cleansing composition of the present invention leads to improved gliding of wet hair, avoiding leaving hair in a dry and/or rough condition.

Still another aspect of the present invention is the method of cleansing and conditioning human hair, comprising a step of applying the composition containing Di-PPG-2 Myreth-10 Adipate, at least one cationic conditioning polymer, at least one surfactant, chosen from anionic, amphoteric and/or nonionic surfactants, and water to the hair, followed by a step of rinsing off the composition after its application within 10 seconds to 5 minutes.

The composition according to the present invention produces positive effects, e.g., it cleanses hair thoroughly and at the same time provides a caring effect to hair, and does not leave the hair in a rough condition.

Detailed Description of the Invention According to the invention, the composition contains Di-PPG-2 Myreth-lO Adipate, which is characterized by the following formula:

Di-PPG-2 Myreth- lO Adipate may be classified as an emollient, a skin conditioning agent, and a nonionic surfactant. Contained in cleansing compositions the advantages of Di-PPG-2 Myreth-lO Adipate have been described of providing mild preparations. Therefore, it has been recommended to use Di-PPG-2 Myreth-lO Adipate in preparations for babies, small children and people with sensitive skin. The use of Di-PPG-2 Myreth- lO Adipate in hair cleansing compositions to provide a conditioning effect has not been described before. Di-PPG-2 Myreth-lO Adipate is used as a silicone replacement, showing a similar conditioning effect as silicone compounds.

Di-PPG-2 Myreth-lO Adipate may be used in water-based and oil-based compositions. Di-PPG-2 Myreth- lO Adipate may be purchased as Cromollient

SCE-LQ-(MH) from CRODA.

According to the invention, the composition contains at least one cationic conditioning polymer. Said cationic conditioning components are polymeric structures, which are of natural origin, namely animal or plant derived, or synthetic origin. The polymers are composed of monomers, either identical ones, resulting in homopolymers, or different ones, resulting in co- or terpolymers.

The cationic groups of the cationic polymers are preferably derived from nitrogen atoms, which are more preferably present in form of primary, secondary, tertiary or quaternary amine groups. The primary, secondary, and tertiary amine groups may be positively charged depending on the pH value. Quaternary amine groups, also called ammonium groups, are permanently positively charged groups, independent of the pH value.

The cationic polymers of natural origin may be based on the guar molecule which is modified in such a way that cationic substituents are introduced or substituents are introduced which are cationic at specific pH values, specifically at those pH values of the hair conditioning compositions. A preferred example of the modified guar molecules is Guar Hydroxypropyltrimonium Chloride, which may be purchased from the Rhodia Company.

Cationic polymers derived from cellulose may also be used in the present invention. Similar to the case of guar, the substituents introduced to cellulose allow the cellulose molecule to have cationic properties.

For manufacturing a batch of one of the compositions mentioned in the present invention, an IKA RW20 digital or IKA Eurostar stir equipment and a stirrer, e.g. a paddle stirrer is used.

Test method

In order to show that the compositions of the present invention are improved in relation to compositions, which are already in the market, panel tests were conducted. The test is carried out by the following procedure:

Caucasian bleached hair tresses are used. The evaluation of the hair tresses were conducted by trained panelists:

Firstly, the amount of foam and the bubble size of the foam was evaluated upon use of the composition on wet hair, while washing. To evaluate the amount of foam, the panelists decide in each test whether the amount of foam, which builds up upon washing, is high, average or less. To evaluate the bubble size the distribution of the big, medium and small bubbles was evaluated in percent of the total bubbles, which appeared upon washing the hair.

After rinsing the shampoo off the hair with water, the detangling and the combability of the hair while combing were evaluated. Furthermore, trained panelists evaluated the structure of the wet hair tresses.

To evaluate other properties of the hair the panelists had the choice between the following statements: The hair feels rough, the hair feels squeaky, the hair feels smooth, the hair feels soft, the hair feels supple, the hair feels waxy and the hair feels coated.

The evaluation was based on a score of 10 points, “0 point” corresponds to“bad”, and“10 points” corresponds to“very good”.

Examples: Table 1

The amounts given refer to active content. * PEG- 150 Pentaerythrityl Tetrastearate may be added as a mixture of PEG- 150 Pentaerythrityl Tetrastearate, PEG-6 Caprylic/Capric Glycerides and water, which may be purchased from the company Croda as Crothix Liquid.

Table 2

Table 3

Source: Panel test, the test was carried out using hair tresses of Caucasian bleached hair.

From the results illustrated in Table 3, comparing a composition without Di-PPG-2 Myreth-10 Adipate and a thickening agent (comparative example, Table 1) to a composition containing said components (Ex. l, Table 1), it becomes obvious that the preparation according to the invention was evaluated better in many aspects. The gliding of the hair is improved during rinsing off and after rinsing, referring to immediate gliding, gliding after 30 seconds and ability of gliding after rinsing. Furthermore, the hair treated with the composition according to the invention (Ex. 1) is easier to detangle and to comb than the hair treated with the comparative composition. Similar results are obtained, when the hair structure of wet hair tresses was evaluated. The tresses treated with the inventive preparation were evaluated better. This is consistent with the properties of hair, being supple, soft, and smooth for hair being treated with the inventive composition. In contrast, the properties rough and squeaky were attributed to hair treated with the comparative composition.

Summing up, the inventive composition provides a conditioning effect resulting in hair that is supple, soft, and smooth.
