Description

Technical area:



[0001] The present invention relates to a liquid composition for wash of scalp and hair or for wash of skin and aimed at alleviating dermatological disorder or disease, the composition comprising at least:
  • 13,5 - 24,0 % Mild wash tensides,
  • 1,0 - 4,7 % Guar HydroxypropyltrimoniumCloride,
  • 0,3 - 1,0 % Piroctone Olamine


[0002] The composition is aimed at use to alleviate psoriasis in the scalp or on other skin, to alleviate eczema or to alleviate ichthyosis.

Background:



[0003] There are a number of dermatological diseases, that are difficult or impossible to remedy. The treatment therefore aims at alleviating the symptoms or the troubles for a very long time, possibly for an entire life. Of course it is important that the symptoms are indeed alleviated and that the treatment itself is not trying. If so the life quality of the affected is raised.

[0004] Psoriasis is such a skin disease. It gives red spots, that scales off and sometimes itches. The outermost layer of the skin is called the epidermis. Outermost in it the horn layer is situated, that is made up of dead skin cells. From beneath new skin cells in a steady pace replaces old dead skin cells that falls off. In a psoriasis condition the cells in the epidermis are formed more quickly than usual, and the cells do not fall off one by one but flakes off in big flakes. Furthermore there is an inflammation in the skin that increases the blood circulation to redden the skin and warm it. Psoriasis often comes in so called relaps. It implies periods with small or no problems and periods when the disease flushes up and the rashes becomes bigger.

[0005] The most common form of psoriasis shows round, a couple of centimeter big flaking rashes, so called plaques. It is therefore called plaque - psoriasis. The skin disorders can be located anywhere on the whole body, but most often on the elbows, the knees, the lower part of the back and the scalp. The coverage of the body can vary from only less than a percent up to the whole or almost the whole body surface. In a mild form of psoriasis, that can be seen as a skin disorder, it can be sufficient to take a bath and to apply a thick layer of softening lotion or ointment several times a week.

[0006] In a more severe form of psoriasis, that should be regarded as a skin disease, a more effective treatment is often wanted using prescribed lotions and ointments. These products can comprise D-vitamin like substances, that have few side effects. But most times these products comprise a strong cortisone, that works fast but has side effects. To reduce the troubles regular treatment is needed for several weeks. After the treatment the rashes will often come back after only a couple of weeks. The side effects make these substances not suitable to use for pregnant and nursing women. There are also compositions that comprise a number of other ingredients to try to decrease the side effects of the strong cortisone and dampen its negative influence on the skin. EP 2 705 847 gives an example of a night cream that in addition to a strong cortisone also comprises a tar extract, an antibiotic component and lanolin, and preferably also almond oil. Furthermore it is preferable to use a day cream that comprises skin caring and skin calming vegetable oils. Combined with washing of the skin this makes three different treatment steps. After 3 months of treatment each one of 3 subjects were three from psoriasis symptoms for almost 1 year before the symptoms started again.

[0007] To treat psoriasis in the scalp a de-scaling anti-dandruff shampoo or a solvent that comprises cortisone is used. The treatment takes away all dead skin or scales. These compositions are fairly aggressive to the skin and are therefore often combined with a sothening and skin calming lotion. But in spite of complicated multi-stage treatments the problems as a rule come back after only a few weeks. This also applies for other skin disorders or skin diseases as eczema on the skin or ichthyosis.

[0008] WO98/52518 discloses compositions such as shampoos comprising piroctone olamine to treat seborrhoeic dermatitis, dandruff and psoriasis.

[0009] There is a need for compositions and treatments that can provide good results at the same time as they are less aggressive to the skin and give less side effects than the current compositions At the same time the treatments should preferably be easy to perform for the sick person.

Summary:



[0010] The present invention intends to decrease one or more of the above stated weaknesses by providing a liquid composition for washing of the scalp and hair or for washing of skin and aimed at alleviating dermatological disorder or disease, the composition comprising at least:

□ 13,5 - 24,0 % Mild wash tensides,

□ 1,0 - 4,7 % Guar HydroxrypropyltrimoniumCloride,

□ 0,3 - 1,0 % Piroctone Olamine



[0011] Further the liquid composition can preferably be washed away with liquid, and preferably after it has been applied for 2 - 5 minutes before it is washed away with liquid. The use of the composition is preferably made where the dermatological disorder or disease is psoriasis on the scalp or on other skin. The use of the composition is preferably made where the dermatological disorder or disease is eczema on the skin or ichthyosis.

Description of preferred embodiments:



[0012] The liquid composition according to the current invention comprises at least:

□ 13,5 - 24,0 % Mild wash tensides,

□ 1,0 - 4,7 % Guar HydroxrypropyltrimoniumCloride, Below called Guar

□ 0,3 - 1,0 % Piroctone Olamine



[0013] The use of mild wash tensides, results in less dry out of the skin, compared to a use of sulfates, which is the most usual. The wash results in that only a part of the dead skin cells or dead skin flakes is washed away, and definitely not all of them as a deflaking shampoo does. This provides a wash more gentle for the skin. Furthermore Guar comprises substances that are conditioning by being softening and re-moisturizing.

[0014] Furthermore Piroctone Olamine is an active ingredient that slows down the growth of the fungus malassezia furfur. Too much of this fungus creates or contributes to scalp problems. The liquid composition washes gently to not dry out the skin, and it is softening and re-moisturizing and it slows the growth of fungus. All this makes the present composition much more gentle than earlier compositions that did take away all dead skin cells and all fungus. After use of such an earlier composition a complementary cream treatment was required to re-moisturize and soften. But still the treatment with an earlier composition and lotion is fairly aggressive. The new liquid composition enables a treatment that is much milder to the skin, so the skin is not irritated. Also it enables a treatment in a single stage instead of normally in 2 or 3 stages. You can see it as a change of paradigm into a more gentle and simple treatment. Tests made show that this especially is the case if the amount of Guar is increased to 1,5% - 3,5%, or preferably 1,5% - 3,0%. At the same time the amount of Piroctone Olamine should be increased to 0,5% - 0;97%, or preferably 0,7% - 0,97%. In the tests made no known side effects were noted.

[0015] The mild wash tensides are one or more of the following wash tensides:

□ Disodium Laureth Sulfosuccinate

□ Lauryl Glucoside

□ Disodium Undecylenamido Mea Sulfosuccinate

□ Cocamidpropyl Betaine



[0016] They have been chosen as they are kind to the skin and do not dry the skin out.

[0017] Use of a liquid composition according to the present invention, where the dermatological disorder or disease is psoriasis in the scalp and the composition is a shampoo or similar. Psoriasis in the scalp is very irritating for the affected person. The affected person has a need to keep his hair and scalp clean. Of course it is an advantage if the wash can be made with a mild shampoo, that does not irritate the scalp, and leads to itch and pruritus. The composition according to the invention can in more severe cases be combined with a cortisone drug, but in many cases the composition can give a good result when used alone, see studies below. The treatment of the affected person is particularly simple in this case. He only changes his earlier shampoo to a shampoo according to the invention

[0018] Use of a composition according to the present invention, where the dermatological disorder or disease is psoriasis on other skin than the skin of the scalp and the composition is a shower gel, shower cream or similar. As the composition is mild to the skin and without known side effects it can be used over the whole body and replace a usual shower cream. Limited tests with the composition used at psoriasis on other skin than in the scalp have showed good results. Test persons for Psoriasis in the scalp that also have psoriasis on other skin have simply noticed that the composition works well for both types of psoriasis, which is perhaps not so strange.

[0019] Use of a composition according to the present invention where the dermatological disorder or disease is eczema in the scalp or on other skin and the composition is a shampoo, shower cream or similar. As the composition is mild to the skin and without known side effects it can be used over the whole body and replace a usual shower cream. Limited tests have shown good results for the type of eczema Seborroic eczema, i.e. Eczema in the scalp.

[0020] Use of a composition according to the present invention, where the dermatological disorder or disease is ichthyosis on the scalp or on other skin and the composition is a shampoo, a shower cream or similar. Limited test with the composition for this aim have given good results for more than 10 persons having the diagnosis ichthyosis on the scalp. Use of a composition according to the present invention, where the composition is washed away with liquid after use. Normally the liquid is water, but of course additives can be used, e.g. Almond oil. Please observe that made studies have used water for wash away.

[0021] Use of a composition as above for wash of scalp or skin, whereby the composition is left to work for 2 - 5 minutes before it is washed away with liquid. This last use has been considered the best and has also been recommended to the subjects in the made studies.

Studies:



[0022] A study has been made for persons with the diagnosis psoriasis in the scalp. More than 50 persons have been using a shampoo according to the invention for 3 months. They have filled in a test protocol before and after the 3 months treatment. In short the result show that approximately 60% of the subjects experienced an improvement through a decrease of their symptoms noted as better or much better. This concerned symptoms of the four types itching, reddening, scaling and scratch marks/ wounds.

[0023] A limited study of more than 10 persons having ichthyosis on the scalp shows that a clear majority experienced a distinct reduction of their symptoms after a 7 week treatment with the shampoo according to the invention. Everybody would also continue using the shampoo.
