TECHNICAL FIELD
[0001] The present invention relates generally to a shampoo composition. More specifically, the present invention provides a rinse-free shampoo composition that exhibits excellent hair cleansing activity, while being devoid of alcoholic solvents.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Shampoos form an essential part of daily routine for cleansing hairs and removing dirt and germs present on the scalp. Shampoo compositions can be broadly classified into two types: a) shampoo compositions that require rinsing with water (also known as “wet shampoo”) to remove the lather along with dirt and b) rinse-free shampoo compositions that do not require rinsing, but generally wiped with a soft cloth.
[0004] Wet shampoos are quite efficient, while they require the use of water, which is not feasible for several sections of persons like those who are bed-ridden or hospitalized. Further, wet shampoo compositions generally contain alcohol and other harsh chemicals, which can cause hair dryness and are as such harmful. Moreover, wet shampoos are often required to be used in conjunction with some conditioners, which give the hair a shiny look and help in maintaining the pH balance of the hair.
[0005] Rinse-free shampoo (also known as dry shampoos), on the other hand, are a great way to reduce or preclude use of water in in hair maintenance. Since no water is required, rinse-free shampoo can be used even by people living in areas where water is scarce, including campers, backpackers, defense personnel in remote areas, and the like.
[0006] However, existing rinse-free shampoo compositions are largely inefficient in removing odor, dirt, sweat, germs and oil. Unlike wet shampoos, they leave behind residues that are difficult to remove. Further, the existing rinse-free shampoo compositions contain strong fragrance and make the hair and scalp skin dry, which may not be suitable for use on patients. Due to these reasons, dry shampoos have not become popular with consumers. So far, existence of such disadvantages has precluded large scale utilization/commercialization of the rinse-free shampoo compositions.
[0007] There is therefore, a need in the art for a rinse-free shampoo composition that is devoid of, or at least alleviates, the disadvantages associated with known rinse-free shampoo compositions. Need is also felt of rinse-free shampoo compositions that does not contain alcoholic solvents while exhibiting the superior cleansing action over the hair without leaving behind any undesirable residue or odor.

OBJECTS OF THE INVENTION

[0042] Foaming Index Measurement Apparatus
[0043] The Foaming indices for different compositions were determined with the help of a cylinder based apparatus.
[0044] The apparatus includes 6 parallel cylinders, each with an internal diameter of about 9 cm and a height of about 29 cm and are fixed to a rotating frame occupying equivalent positions in the frame. Each cylinder is provided with a graduated scale to measure the height of the foam of the composition under investigation. These cylinders are closed at the top with the help of a removable lid, wherein the lid is provided with a 5 mm hole to allow introduction of additives (soil composition). The hole is closed with a rubber bunk, when the cylinders are subjected to rotation. The frame holding the cylinders is rotated by an electric motor that rotates the fixed cylinders along an axis perpendicular to main axis of the cylinders, such that the cylinder is cut in the middle of their length, in the plane of the frame.
[0045] Compositions under investigation move or flow in the cylinder during rotation, thereby generating a turbulence that leads to the formation of foam. Cylinders were rotated at a rotation speed of about 20 rpm, by series of 10 rotations (each lasting for about 30 seconds) followed by a rest of 3 minutes between each series to allow a measure of the foam height (at the end of the 3 minutes). The foam height is determined by reading the graduated scale when the cylinders are in a vertical position after rotation:
[0046] Protocol for measuring Foaming Index of the given composition:
[0047] About 500 ml of composition to be investigated (maintained at 20 °C) was slowly poured into the cylinder by avoiding the formation of foam. The rotating frame holding the cylinders was rotated at a rotation speed of about 20 rotations per minute (rpm), by series of 10 rotations (each lasting for about 30 seconds) followed by a rest of 3 minutes between each series to allow a measure of the foam height (at the end of the 3 minutes).
[0048] Compositions under investigation:

16 Composition as prepared in Example 1 2.9 cm
17 Composition as prepared in Example 2 3.1 cm

[0049] Results presented as part of the Table 1 hereinabove clearly indicate that a surfactant combination including TEA-Lauryl Sulfate and cocamidopropyl Betaine in defined concentration range (viz. cocamidopropyl betaine in an amount ranging from about 0.8% to about 1.2% by weight of the shampoo composition and TEA-Lauryl Sulfate in an amount ranging from about 2.4% to about 3.2% by weight of the shampoo composition) exhibits an exceptional synergistic behaviour in terms of surprisingly low foaming index when compared to utilization thereof individually.
[0050] Foam Maintenance Index Measurement
[0051] The Foam Maintenance indices of compositions were determined with the help of a cylinder based apparatus utilized for foaming index determination experiment.
[0052] About 500 ml of composition to be investigated (maintained at 20 °C) was slowly poured into the cylinder by avoiding the formation of foam. The rotating frame holding the cylinders was rotated at a rotation speed of about 20 rotations per minute (rpm), by series of 10 rotations (each lasting for about 30 seconds) followed by a rest of 3 minutes between each series to allow a measure of the foam height (at the end of the 3 minutes).
[0053] To insure the availability of foam for a given period of time to serve its purpose of cleansing; a foam maintenance test was conducted. For this, an artificial soil composition was prepared for testing the shampoo composition effectiveness.
[0054] Composition of Artificial sebum: An artificial sebum composition was used as an additive for measuring the sustainability of the foam formed in foaming index apparatus described above. Artificial sebum (including a combination of synthetic sebum and soil/clay) simulates greasy soils such as soils coming from the human scalp, mixed with clay (bentonite). The weight ratio between synthetic sebum and clay is 10:4.
[0055] Composition for 850 g of synthetic sebum:
Table 2: Composition of Synthetic sebum
[0056] The above ingredients (synthetic sebum) were placed in a glass beaker and heated to a temperature of about 80°C for 15 minutes, under magnetic stirring to obtain a transparent and light colour liquid and can be stored for several weeks as solid material after cooling. For the foam maintenance evaluations, the desired artificial sebum composition was prepared by melting about 10 g of synthetic sebum at a temperature of about 80°C followed by addition of about 4g of clay, under magnetic stirring.
[0057] Foam maintenance Test:
[0058] After the 10th series of (20 rotations + 3 minutes resting times), artificial sebum addition was effected by adding 5 droplets (about 0.15 g) of liquid and warm soil (80°C) into the cylinder. The cylinder was given 10 subsequent rotations at 20 rpm. The foam height was measured 3 minutes after the 10 rotations (total of 200+10=210 rotations). Repeat the artificial sebum addition implement with adding the artificial sebum just after the foam height measure and just before the subsequent rotation. This rotation, wait, measure, artificial sebum addition implement was repeated, until the foam height reaches a value of about 1.6 cm. Foam Maintenance Time (in seconds) required for foam to subside (i.e. decrease in height of foam) from initial 1.6 cm to 1.0 cm was measured in seconds. More time required to subside the foam indicates the stability of the composition to effectively clean the soil/dirt that need to cleaned from the human hair and scalp.

[0059] Results presented as part of the Table 1 and Table 3 hereinabove clearly indicate that a surfactant combination including TEA-Lauryl sulfate (triethanolamine lauryl sulfate) and cocamidopropyl betaine in defined concentration range (viz. cocamidopropyl betaine in an amount ranging from about 0.8% to about 1.2% by weight of the shampoo composition and TEA-Lauryl Sulfate in an amount ranging from about 2.4% to about 3.2% by weight of the shampoo composition) exhibits an exceptional synergistic behavior in terms of surprisingly low foaming index when compared to utilization thereof individually, while retaining its cleaning efficacy. Accordingly, the surfactant combination of the present invention is found to be of specific utility in the rinse-free shampoo compositions.
