Description

Composition comprising a thickening polymer, a derivative of menthol and a particular non-ionic surfactant

The present invention relates to a composition comprising in a hydro-alcoho lic medium a thickening polymer, a derivative of mentho l and a particular non-ionic surfactant.

The present invention also relates to a method of cosmetic treatment wherein such a composition is applied on keratin substrates.

Finally the present invention relates to the use o f such a composition for conferring a feeling o f freshness and cleanliness to keratin substrates, and in particular to human keratin substrates such as the skin, the scalp and the hair.

The hair and the scalp are generally damaged and embrittled by the action o f external atmospheric agents such as light and bad weather, external aggression such as pollution, and also by mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and/or relaxing. These damages can induce an increased sebum secretion by the scalp .

Furthermore, in certain circumstances such as under sun or hamam exposures, the keratin substrates, such as the skin and the scalp, are likely to sweat, leading to sebum secretion. An excess o f sebum secretion on the scalp renders the hair greasy and decreases its cosmetic and styling properties, such as its appearance and manageability.

In addition, the presence o f sebum reduces the freshness perceived on the scalp and the hair and provides a sensation o f oily feel.

This greasy aspect of the hair is also a nuisance from an aesthetic point of view for the consumers . In particular, the hair looks lank and heavy.

Therefore, there is a real need to develop compositions that are able to reduce the quantity o f sebum present on the skin, the hair or the scalp . These compositions shall remedy the drawbacks mentioned above, and shall confer good styling properties, such as a good manageability, to the hair, and provide a fresh and comfortable feel to the scalp or the skin.

The Applicant has now discovered that a composition, comprising in a hydro-alcoho lic medium a thickening polymer, a derivative o f mentho l and a particular non-ionic surfactant, makes it possible to achieve the obj ectives outlined above.

In particular, it has been found that such a combination is able to significantly reduce the quantity o f sebum on the scalp, for example post hamam exposure, decreasing thus the oily feel on scalp and hair and leading to a better manageability and a better styling of the hair.

Thus, the subj ect o f the invention is especially a composition comprising

- one or more thickening polymer(s),

- one or more compound(s) of formula (I)

wherein, Ri denotes a hydrogen atom or a linear or branched, saturated or unsaturated, C 1 -C 12 alkyl radical, optionally substituted by one or more hydroxyl groups, and/or one or more NRR ' groups with R and R ' , identical or different, denoting a hydrogen atom or a linear or branched, saturated or unsaturated, C 1 - C4 alkyl radical,

- one or more non-ionic surfactant(s) chosen from oxyalkylenated C₈ - C30 fatty alcoho ls,

- one or more water-soluble organic so lvent(s) chosen from alcoho ls comprising a C i -Cs alkyl chain, and

- water.

The composition o f the present invention is able to reduce the quantity o f sebum on the skin and the scalp . In other words, the composition adsorbs the sebum and decreases the greasy feel perceived on the scalp . It leads to a fresh and clean sensation and a sustained cooling and soothing on the skin and the scalp .

The composition according to the present invention preferably aims at a leave-on application on the hair and on the scalp, which results in better manageability, and a cleaner feel when in contact with keratinous substrate along with substantial cooling o f the dermal layer supporting the keratinous substrate and sebum absorption.

Preferably, the composition according to the present invention is a cleansing agent that can be used as a leave-on product, having good sebum absorption property together with a substantial cooling effect, which then conducts to an important feeling o f cleanliness and freshness on the scalp and the hair, after application.

In particular, the composition according to the present invention decreases the warm feeling on the scalp and on the hair. The feeling of freshness is significant, and is of the order of 7°C directly after application.

In addition, hair treated with the composition o f the present invention is lighter, more manageable and easier to style. Its appearance is improved; the hair looks less greasy and shinier.

The composition also helps to protect the hair against external aggression such as pollution.

The present invention also relates to a method of cosmetic treatment of keratin substrates, in particular human keratin substrates such as the skin, the scalp and the hair, wherein the cosmetic composition o f the invention is applied on said keratin substrates.

Another obj ect of the present invention concerns the use o f the composition o f the present invention for conferring a feeling o f freshness and cleanliness to keratin substrates, and in particular to human keratin substrates such as the skin, the scalp and the hair.

Other subj ects, characteristics, aspects and advantages o f the invention will emerge even more clearly on reading the description and the example that follows. In that which fo llows and unless otherwise indicated, the limits of a range of values are included within this range, in particular in the expressions "of between" and "ranging from ... to

EXAMPLE

In the examp les that fo llow and unless otherwise indicated, the amounts are given as mass percentages of active material relative to the total weight of the composition (% AM = % active matter) .

1 . Compositions

The fo llowing compositions A (invention) and B (comparative) were prepared from the ingredients indicated, in percentage by mass, in the table below.

Carbopol Ultrez 10 Polymer from Lubrizol 2. Method

5 squares (sites) of 2cm* 2cm have been drawn on each upper part and lower part of forearm o f both hands o f two vo lunteers. In other words, 20 squares have been drawn per vo lunteer (giving 40 squares in total) .

0.0025 g of refined coconut oil were then poured on each of the 40 squares to simulate sebum secretion.

The amount of oil o f 10 out of 20 squares on each vo lunteer were measured and corresponded to the baselines (giving 20 baselines in total) .

The measurement o f the amount of oil was based on grease spot photometry. The mat tape o f the Sebumeter^® was brought into contact with the skin or the scalp . It became transparent in relation to the sebum on the surface of the measurement area. The tape was then inserted into the aperture of the device and the transparency was measured by a photocell. The light transmission represents the sebum content.

Then, O . l g of compositions (A) or (B) were randomly poured on the 10 left squares of each vo lunteer (giving 5 sites for composition A and 5 sites for composition B , per vo lunteer) . After a leave-on time of 10 minutes, each square was dabbed 12 times with a cotton pad (2 * 2 cm, 0.5 mm thick) during 30 seconds in total before measuring the amount of oil.

3. Results

The sebumeter readings measured before and after app lication of compositions (A) or (B), as well as their difference, are respectively mentioned in tables 1 and 2 below.

Average 218.2 163.5 24.8

Table 2: results obtained for t le composition B (comparative)

The results show that the claimed composition (A), comprising a non-ionic surfactant chosen from oxyalkylenated C 8 - C 30 fatty alcohols, has a better anti-sebum efficiency than the comparative composition (B), lacking such a non-ionic surfactant.

Indeed, after application o f composition (A) almost 25 % o f o il are removed from the skin, while composition (B) can only remove 15 % of oil.

The composition o f the present invention is therefore a better cleansing agent, or sebum remover, in comparison to the comparative composition.
