Description

Silicone-free shampoo composition

Technical field

The present invention belongs to the cosmetic field and relates to a silicone-free shampoo composition for human hair comprising at least one PPG-alkyl ether， at least one cationic conditioning polymer and at least one anionic， amphoteric and/or non-ionic surfactant.

Technical background

A beautiful and attractive appearance is a desire for many people. One of the main aspects， which defines such a positive appearance， is the look of the hair of the head. In order to take care on the hair customers usually apply a number of cosmetic products on a daily basis. Typically， this starts with washing the hair using a commercial shampoo product. Such shampoos contain surfactants which remove excess of soil or sebum from the hair. The surfactants are usually chosen from anionic， cationic， amphoteric and non-ionic surfactants. In most cases anionic surfactants are contained in the shampoo compositions， as they promote the formation of foam and ensure an effective removal of dirt， soil and/or sebum.

However， it is a well-known fact that commercial shampoo composition often remove lipids and proteins from the hair and the scalp， as well. This may lead to a dry scalp or it may be found that the structure of the hair may be negatively affected such that the shampoo product leaves the hair in dry and unkempt condition. As consequence the hair might be difficult to detangled and/or difficult to comb after rinsing the shampoo off the hair. Furthermore， the hair often feels squeaky and rough， for example， while gliding with the fingers along the hair the fingers may feel some resistance.

Generally， there are two ways to improve the detangling and the combability of the hair. Firstly， a leave-in or rinse-off conditioning composition may be applied after washing to the hair. Such a composition usually contains as surfactants solely cationic surfactants， which， in difference to other surfactants， do not allow for an effective cleaning of the hair. Instead， the hydrophilic ends of the cationic surfactants may bind to the creatine of the hair and the hydrophobic ends of the cationic surfactants may act as protective a layer for the hair. Furthermore， such conditioning compositions often contain for example film-forming polymers， moisturizers， hydrolyzed proteins and/or antistatic agents. Nevertheless， the use of a leave-in or rinse-off conditioner requires a second， time consuming step after washing the hair. Therefore， it is desirable to provide a composition which cleans and conditions the hair simultaneously.

The second way to improve the detangling and the combability of the hair can be achieved by applying a shampoo composition which contains silicone components. Silicones are excellent conditioner which may be effectively deposited onto the hair even while being implemented in a shampoo composition containing anionic， amphoteric and/or non-ionic surfactants. Thereby， the silicones provide improved compatibility， feel， softness， and lessening frizz. However， it is a well-known 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. In particular， this can become an issue for consumers with fine hair wishing to build-up volume. Therefore， it remains desirable to provide alternative silicone-free compositions， which provide conditioning effects to the hair while reducing the effect of the hair being weighed down by silicone-residues.

It is often found that silicone-free shampoo composition have a number of disadvantages. In particular， those shampoos often do not allow for an effective deposition of conditioning polymers onto the hair in the presence of anionic surfactants. Therefore， it is hardly possible to provide a silicone-free shampoo composition which allows to clean the hair and to apply a protective conditioning layer simultaneously. Additionally， silicone-free shampoo compositions do often not allow a sufficiently easy detangling while combing the wet hair after washing and/or the combability of the hair is adversely affected after washing. Furthermore， many silicone-free shampoo compositions do not build-up a large amount of foam while washing the hair， wherein insufficiently small foam-bubbles are formed.

Summary of Invention

The objective of the present invention is therefore， to provide a silicone-free shampoo composition， which allows for an effective cleaning of the hair and which does not exhibit the disadvantages discussed above.

WO 2014077826 A1 discloses a cleansing composition containing anionic surfactants and alkoxylated alkyl ether. The document does not disclose compositions containing cationic conditioning polymers. Therefore， the document does not direct the skilled person to the objective of the present invention.

The applicant has surprisingly discovered that a silicone-free shampoo composition comprising at least one PPG-alkyl ether， at least one cationic conditioning polymer and at least one anionic， amphoteric and/or non-ionic surfactant allows for a significant improved deposition of conditioning polymers onto the hair. Moreover， it was surprisingly found that such a silicone-free shampoo composition allows for a significant improvement of the detangling and/or combability of the hair， after use of the shampoo composition. At the same time， shampoo compositions according to the invention allow for an improved foam formation during washing the hair.

Inv ＝ Inventive example， according to the invention

A study was carried out in order to evaluate the properties of the inventive composition Ex.2 in comparison to the composition Ex. 1， which is not in accordance with the invention. The assessment was carried out by trained hairdressers， who evaluated the state of the hair and the shampoo properties. The test was carried out using hair tresses of Asian black hair.

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 hairdressers needed to 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 by the hair dresser. Furthermore， the hair dresser evaluated the structure of the wet hair dresses. For these three evaluations a score range was used from 1 being bad to 10 being very good.

Finally， the hair dresser were asked how they would describe the hair after the use of the shampoo. They had the choice between the following statements： The hair feels rough， hair feels squeaky， the hair feels supple， the hair feels waxy and the hair feels coated. Per shampoo composition the hairdressers could distribute points， to which statements they agree.

All the results are presented in the following Table：

Salon test	Ex. 1	Ex. 2
Foam amount high	0	2
Foam amount average	6	4
Foam amount less	0	0
--------------
Proportion of large bubbles	9.17％	14.17％
Proportion of medium bubbles	34.17％	41.67％
Proportion of small bubbles	56.66％	44.16％
-------------
Detangling (combing)	4.83	7.5
Combability	4.0	7.33
Hair structure of wet tresses	4.17	5.83
--------------
Hair feels rough	3	0
Hair feels squeaky	3	0
Hair feels supple	0	3
Hair feels waxy	0	0
Hair feels coated	0	3

Analyzing the results presented in the table above， it was found that the shampoo composition according to the invention allows to form a larger amount of foam and， additionally， the distribution of the bubble size of the foam is shifted towards larger bubbles. Even more outstanding is the performance of the shampoo composition according to the invention regarding the detangling and the combability of the hair. For both parameters a significant improvement was found. Furthermore， the structure of the hair tresses was found to be improved. Following the statements of the hair dressers， it can be noted that after use the shampoo according to the invention a coating of the hair is achieved， whereby the hair feels supple. Thus， an improved deposition was achieved.
