Description

The invention relates to the field of cosmetics and the like. toilet preparations, in particular, to products intended for washing hair and containing substances that improve the condition of the hair.

Known shampoo containing water as a solvent, sodium laureth sulfate as a foaming agent, coconut diethanolamide as a thickener, citric acid as an acidity regulator, preservative, biologically active ingredient, flavor and consistency enhancer (RU No. 2115406, A 61 K 7 / 08, 1998).

Known shampoo, having a good emollient effect while maintaining high foaming performance, due to the composition used in its composition does not have properties that contribute to the prevention of skin diseases.

A more perfect and closest analogue of the claimed technical essence and the achieved result is a shampoo containing water as a solvent, sodium laureth sulfate as a foaming agent, coconut oil diethanolamide as a thickener, citric acid as an acidity regulator, methyl paraben as a preservative, wood tar as a biologically active ingredient, flavoring and consistency enhancer (WO No. 8603679, A 61 K 33/44, 1986).

However, the composition of the indicated shampoo, in order to ensure a therapeutic and prophylactic effect with the composition of ingredients established by the recipe, requires a high content of a biologically active ingredient - wood tar, which in turn, in order to maintain high foaming performance, necessitates an increase in the content of the foaming agent to more than 30 wt.%. The latter is especially significant, since it can cause an allergic reaction and irritation of the scalp and mucous membranes of the eyes.

The technical result that can be obtained using the inventive shampoo is to acquire antimicrobial, anti-inflammatory, wound healing and nutritional properties.

The specified technical result is achieved by shampoo containing water as a solvent, sodium laureth sulfate as a foaming agent, coconut diethanolamide as a thickener, citric acid as an acidity regulator, methyl paraben methyl paraben as a preservative, wood tar as a biologically active ingredient, flavoring and enhancer consistency, due to the fact that it additionally contains water-alcohol or water-alcohol-glycerin or propylene glycol extracts of birches O buds and leaves and birch wood tar with the following ratio of ingredients, wt% used as the active ingredient.;

laureth sodium sulfate - 16-30,

coconut oil diethanolamide - 5.5-10,

citric acid - 0.01-0.1,

methyl paraben - 0.05-0.3,

tar birch tar - 0.05-0.5,

extracts of birch buds - 0.1-5.0,

extracts of birch leaves - 0.1-5.0,

flavoring - 0.1-0.5,

consistency enhancer - 0.2-3,

water is the rest.

Shampoo is prepared by dissolving in water an acidity regulator, preservative (methyl paraben, for example BATCH NO 3703-400624 V991119-3), a biologically active ingredient (birch tar, for example TU 13-0279886-28-104-87) with extracts of birch buds and leaves (for example, according to the certificate of conformity No.ROSS. RU. PR14.N00055), flavoring, consistency enhancer and subsequent introduction into the composition of a foaming agent and thickener, for example, in the form of a paste-like substance TEXAPON No. 70 (number CASR 68891-38-3) containing sodium lauryl sulfoethoxylate (l aureth sodium sulfate), and CAMERLAN KD liquid product (CASR155-06-6) containing coconut oil fatty acid diethanolamide.

The content of sodium laureth sulfate in the amount of 16-30 wt.% Reduced in comparison with the analogue, provided due to the presence of extracts of birch buds and leaves with less tar, is the most optimal both for foaming and for exposure to the skin and mucous membranes of the eye .

Under these conditions, the increased content of coconut oil diethanolamide in comparison with the analogue allows reducing the amount of table salt added to the shampoo as a consistency enhancer, which ultimately improves the dermatological properties of the shampoo (does not dry the scalp and hair) and allows the shampoo to be used for frequent washing of the head and body . The use of the claimed shampoo has a healing effect on the skin and hair with eczema, dermatitis, various inflammatory processes, seborrhea, psoriasis and other skin diseases, as illustrated by the following examples.

To conduct shampoo tests, a focus group was created in the amount of 15 people from among people suffering from various skin diseases and different types of hair.

Example 1

Shampoo was prepared according to the following recipe: sodium laureth sulfate - 30 wt.%, Coconut oil diethanolamide - 10 wt.%, Citric acid - 0.1 wt.%, Methyl paraben - 0.3 wt.%, Birch tar - 0.5 wt.%, birch bud extract - 5.0 wt.%, birch leaf extract - 5.0 wt.%, flavoring - 0.5 wt.%, consistency enhancer - 0.3 wt.%; water is the rest.

The generated samples were used for 4 weeks (months) 2 times a week.

After 1 week, all subjects noted the excellent foaming and washing properties of the shampoo. In the state of hair and skin of the body, no special changes were observed.

After 2 weeks, four people noted that the condition of the scalp and body did not change. Three people noted a slight disappearance of itching and irritation. Eight people showed a significant improvement in their hair and scalp. The psoriatic nodes in the subjects prone to skin diseases turned pale, the scalp became less irritable, the hair acquired a lively and healthy appearance.

After 3 weeks, six of the subjects noted special changes in the condition of the scalp and body, the redness of the psoriasis nodes disappeared, the irritation and itching stopped, and the hair acquired a well-groomed healthy appearance. Seven people with dermatitis noted that shampoo has a beneficial effect on the scalp and body, soothes, relieves irritation and inflammation. Two people did not notice any significant improvements in the scalp and body, while at the same time the hair became more shiny and healthy. The whole group noted the good quality of the shampoo.

After 4 weeks, all subjects noted that the hair and scalp acquired a healthy appearance, hair growth improved, their resistance increased, dandruff, itching and inflammatory processes disappeared. The excellent foaming and washing properties of the shampoo were also noted.

Example 2

Shampoo was prepared according to the following recipe and distributed to members of the previously created group:

sodium laureth sulfate - 16.0 wt.%,

coconut oil diethanolamide - 5.5 wt.%,

citric acid - 0.01 wt.%,

methyl paraben - 0.05 wt.%,

tar birch tar - 0.05 wt.%,

birch bud extract - 0.1 wt.%,

birch leaf extract - 0.1 wt.%,

flavoring - 0.1 wt.%,

consistency enhancer - 0.2 wt.%;

water is the rest.

The tests were carried out in the same way as in the first example - 4 weeks for 15 subjects.

After 1 week, all subjects noted good foaming and washing properties of the shampoo. No significant changes were observed.

After 2 weeks, the subjects with signs of dermatitis and inflammatory elements on the skin noted that the shampoo does not cause irritation, the scalp calms down, the hair becomes shiny and healthy. Patients with psoriasis did not notice significant improvements, but noted that the nodules became paler, the inflammation disappeared.

After 3 weeks, out of fifteen people in the subjects, twelve people noted that shampoo favorably affects hair, scalp and body. One person did not feel any improvement. Two people noted slight changes in the condition of the skin and hair.

After 4 weeks, all subjects noted improvement in hair and body skin, increased hair tone, decreased hair loss (15-20%), increased microcirculation in the hair follicle, due to which the scalp and body became healthy (inflammation decreased, itching disappeared, psoriasis nodules disappeared).

Example 3

Shampoo was prepared according to the following recipe:

sodium laureth sulfate - 23.0 wt.%,

coconut oil diethanolamide - 7.75 wt.%,

citric acid - 0.055 wt.%,

methyl paraben - 0.175 wt.%,

birch wood tar - 0.275 wt.%,

flavoring - 0.3 wt.%,

consistency enhancer - 1.6 wt.%;

water is the rest.

A shampoo was prepared with the introduction of alcoholic extracts of birch buds and leaves into the formulation, and distributed to the same 15 people in the created group. The observation was carried out for a month with a weekly analysis.

After 1 week, all fifteen people showed no significant changes, but everyone noted that the shampoo washes and cleans hair perfectly.

After 2 weeks, noticeable changes occurred depending on the type of hair. Subjects with a dry hair type did not feel any significant changes, and subjects with a greasy hair type felt an improvement in their hair condition, hair oily hair was noticeably lost, and a clean look and volume remained longer than usual. The scalp did not feel itching or irritation. All subjects noted excellent foaming and washing properties in the shampoo.

After 3 weeks, two people from the group after applying the shampoo showed no particular changes, but they noted that the shampoo foams well and washes hair. Eight people noted a significant improvement, their hair became less oily, maintained a clean appearance throughout the week, acquired a lively well-groomed appearance, shine and volume. The scalp did not feel itching, the inflammatory processes stopped, and peeling of the skin decreased.

Five people noted the good foaming and washing properties of the shampoo, hair acquired a brilliant healthy look.

After 4 weeks, the subjects had a noticeable distinction depending on the type of hair - those with a dry hair type did not find any significant changes in the condition of the scalp, and the group having a greasy hair type noted significant improvements, the hairiness, itching and discomfort completely disappeared, and inflammatory processes in the scalp, volume increased, hair loss decreased, dandruff disappeared. All subjects noted the excellent foaming and washing properties of the shampoo.

water is the rest.

After 1 week, no significant changes were found in all the subjects, but everyone noted the good washing properties of the shampoo.

After 2 weeks, two people showed no changes, but they did not feel discomfort in the condition of the hair and skin of the body. Eight people noted improvements, increased tone of hair density, a tendency to reduce itching, inflammatory processes and psoriasis nodules on the scalp, and peeling of the scalp. Five people noted the good condition of the hair, their color improved and the purity and volume remained longer. All subjects noted the good quality of the shampoo.

After 3-4 weeks, the condition of the hair and scalp improved significantly in eight people. The growth and decrease in hair loss is noticeable, their resistance has increased, the hair has acquired a lively and well-groomed appearance, the itching and inflammatory processes of the scalp have stopped. Six people noted the disappearance of dandruff. Two people noted the disappearance of discomfort and the good washing and foaming properties of the shampoo. Five people prone to dermatitis and psoriasis noted that shampoo improves the condition of the scalp, soothes and relieves irritation and inflammation, itching and discomfort. The nodules on the scalp disappear. Hair takes on a healthy, well-groomed appearance.

Example 5

Shampoo was made on propylene glycol extracts of birch buds and leaves:

sodium laureth sulfate - 23.0 wt.%,

coconut oil diethanolamide - 7.75 wt.%,

citric acid - 0.055 wt.%,

methyl paraben - 0.175 wt.%,

birch wood tar - 0.275 wt.%,

propylene glycol extract of birch buds - 2.55 wt.%,

propylene glycol extract of birch leaves - 2.55 wt.%,

flavoring - 0.3 wt.%,

consistency enhancer - 1.6 wt.%;

water is the rest.

After 1 week, all fifteen people did not find any special changes in the condition of the hair and skin of the body, but noted the good foaming and washing properties of the shampoo.

After 2 weeks, subjects with a dry hair type noticed improvements in the condition of their hair and skin. Itching and irritability decreased, psoriasis nodules became paler, tone and density of hair increased. The part of the group that has a greasy type of hair did not feel much improvement, but noted the good washing and foaming properties of the shampoo.

After 3 weeks, two of the fifteen subjects did not feel improvement in the condition of their hair and skin. Eight people, mostly prone to dry hair, noted significant improvements, itching and inflammation disappeared, dandruff decreased significantly, and hair resistance increased. Hair acquired shine and well-groomed appearance. Five people noted the disappearance of discomfort in the hair and scalp. Hair acquired a healthy look.

After 4 weeks, two people did not notice any significant changes in the condition of the hair and skin of the body. Eight people noted that itching, dandruff and inflammatory processes, as well as psoriatic nodules on the scalp disappeared. Hair is easy to comb, does not break and falls out a little. Five people noted that the tone and density of hair increased, decreased by 30% of their loss, increased microcirculation in the hair follicle, so that the hair and skin of the body acquired a healthy and well-groomed appearance. The entire group of subjects noted the excellent foaming and washing properties of the shampoo.

Thus, the following conclusions can be made.

After applying the shampoo, regardless of the composition of the formulation (five different options), a positive effect of the shampoo on the condition of the hair and skin of the body was noted. All subjects improved their hair and skin condition by at least 30-35%. Shampoo does not irritate the skin and does not cause allergic reactions, is well tolerated by any type of hair and does not cause negative sensations, it foams and cleanses the hair perfectly.

Thanks to the introduction of extracts of birch leaves and buds, which enhance the effect of tar, the shampoo has an anti-inflammatory effect, which ultimately leads to the disappearance of dandruff, psoriasis, strengthening and hair growth.
