Description

Clear shampoo composition containing capsules and method of making the same

The present invention relates to a transparent shampoo composition containing a capsule and a method for manufacturing the same, and more particularly, to a transparent shampoo composition in which the conditioning (pigment effect) is improved while the capsule is uniformly and stably dispersed in the transparent shampoo composition. .

In general, the shampoo is applied to the hair and the conditioning effect is exerted during the lathering process and the rinsing process. That is, in the step of generating bubbles by applying shampoo to the hair, the hydrophilic group and the lipophilic group of the surfactant are present in the form of a cluster that surrounds the contaminants by interacting with an external oily pollutant and secreted sebum. When the surfactant is diluted below the critical micelle concentration (CMC), the phase of the uniform shampoo will consist of a conditioning phase and an aqueous phase consisting of cationic polymers, silicones, other oils, and polymer-surfactant complexes. into the water phase, which results in the removal of contamination and the presence of components in the conditioning phase by adsorption of the contaminant-contaminant-cluster in the foaming phase to excess water. Conditioning, which eliminates decontamination and conditioning to improve hair condition, All.

As such, since the cleaning and conditioning effects are competing with each other, conventionally, shampoo compositions containing capsules filled with oily conditioning substances have been known in an effort to improve the conditioning effect. This composition is not only a shampoo composition that uses PVM / MA Decadiene Crosspolymer as a dispersant to disperse and keep the capsule stable, but also an opaque composition that does not take full advantage of the aesthetic benefits of the capsule, as well as PVM / MA Decadiene Crosspolymer. When xanthan gum or polyvinyl alcohol (PVA) was used as a dispersant, the capsules did not stabilize. Monoethanolamine or diethanolamine, which can be used as a dispersing neutralizer, reacts with carbonyl groups present in most perfume compounds to form schiff bases as shown in the following formula, which discolors the shampoo composition. There is a problem.

Here, R NH ₂ is a primary or secondary amine and R '(CO) R''represents a carbonyl group of the perfume.

In general, the transparent shampoo composition which is distributed in general is inferior in hairstyling effect because it is washed out in a washing process using a water-soluble conditioning agent such as dimethicone copolyol (US Pat. No. 5,145,607), and microemulsion of silicone oil is applied to the transparent shampoo composition Although a compounding technique (Japanese Laid-open Patent No. 86/161214) has been introduced, the transparent shampoo composition containing the microemulsion conditioning agent does not stabilize the capsules with time, especially under high temperature (40 ^o C to 50 ^o C). There have been many difficulties in improving the conditioning effect over the known techniques. Therefore, as a way to improve the quality of the conventional transparent shampoo, while utilizing the beautiful appearance of the transparent shampoo composition to the maximum, capsule suppliers such as Cognis and Lopo technology include capsules in carbomer (carboxyvinylpolymer) shampoo prescription. An example prescription is introduced. Carboxyvinyl polymer, widely known as Carbopol, is a water-soluble polymer and has excellent dispersibility, which makes it possible to stably disperse the capsule in the transparent shampoo composition. However, the use of an excessive amount of surfactant reduces the transmittance of the ionic surfactant. Conditioning ingredients to be minimized (8 to 9% by weight of the total amount of the composition) and excessive amounts of ethanol or propylene glycol (more than 5% by weight of the composition) should be used. Because of their limited appearance, they can provide an aesthetic advantage with a beautiful appearance, but the problem is that the product performance is unsatisfactory and the amount of bubbles is insufficient, so the function as a shampoo is insufficient.

The present invention has been proposed to solve the above-mentioned problems, and has an object of providing a transparent shampoo composition in which the capsule is stably dispersed during a long storage period and provides a good hair-setting effect on the hair.

The present invention provides a polyether-1 or PEG-180 / Octoxynol-40 / TMMG nose with about 0.5% to about 1.2% by weight of xanthan gum having a light transmittance of 80% T or more in a 0.5% solution as a dispersion stabilizer. A transparent shampoo composition is provided which comprises 0.2% to 0.5% by weight of at least one dispersion stabilizer selected from polymer or PEG-180 / Laureth-50 / TMMG copolymer and a capsule material.

In the method for preparing a transparent shampoo composition of the present invention, by adding purified water to a secondary dissolution tank having a heating facility, the xanthan gum solution dispersed in propylene glycol in advance is added to the secondary dissolution tank, and completely dissolved while heating and stirring to 65 ^° C. Dissolving by stirring to increase stirring speed if necessary, and xanthan gum to increase the speed of the turbine blade to form a vortex and then disperse dissolution; Note the solution of the previous step was transferred to a stirring tank (Main Batch) was fully defoamed in the following, while slowly stirring and careful to put a surface active agent, solubilizing agents, and the xanthan gum solution is uniformly dissolved with a surfactant, this step also PURETHIX ^TM Charging and stirring sufficiently; Cooling to below 50 ^° C. and then slowly adding thickener, hair conditioner and the like and continuing stirring; Cooling to 40 ^° C. or lower, adding preservatives, flavorings, and pigments, stirring appropriately, and then defoaming; The process consists of adding capsules and excess purified water and stirring appropriately to avoid bubbles.

3.3 Evenly spread the shampoo all over the hair with your fingertips.

3.4 Comb back and forth a total of 20 times. It is important to comb over the handle of the comb.

3.5 Rinse thoroughly with plenty of water so that there is no residual amount of shampoo (keep time / flow constant), then remove excess water and place it on the tray.

Note: The same comb can be used repeatedly for the same shampoo. When shampooing with another shampoo, wash the comb with a brush and remove the silicone attached to the comb.

Combing experiment of wet hair for Example 1 and Comparative Example 2 of the present invention,

1. First, prepare 6 hair bundles and number them (1, 2, 3, 4, 5, 6). Instron test is performed on the wet hair which is not treated with shampoo by the method of 2 above.

2. Then, after shampooing each of the compositions of Example 1 (hair bundles 1, 2, 3) and Comparative Example 2 (use of hair bundles 4, 5, 6) in the order of 3 above, and then wipe with index finger-stop Lower and evenly, comb back and forth with a comb 20 times in total, rinse and remove excess water, immerse the hair bundle 3 times in 2 liter beaker water, and then tangle.

3. Walk on the load cell, calibrate and start combing.

4. After combing, the comb should be screwed in unused or replaced with a new one.

5. Test three times for each hair.

6. Look at the measurement results and calculate and evaluate the following formula. The evaluation is peak combing load (PCL) and average combing load (ACL), where PCL is the load value (in grams) of the point where the most load is applied when combing hair, and ACL is the average load load when combing. . The more combing to hair, the smaller PCL and ACL values. Obtain PCL and ACL, and then calculate Total Percent Change in PCL and Total Percent Change in ACL as

% Percent change in PCL =

(Average of PCL value after processing-average of PCL value after processing) / average of PCL value without processing X 100

% Percent change in ACL =

(Average ACL value after processing-Average of unprocessed ACL value) / Average of unprocessed ACL value X 100

The test condition is that the hair bundle weighs 4.5 grams (6.5 inches), the hair condition (relative humidity / temperature) is 50% / 25 ^o C, and the comb is made of a cylindrical matt stainless steel comb. Combs of aluminum frame with a comb diameter of 2.2 mm and a gap of 1.5 mm between them are used.

Cross head speed is 500.00 mm / min. Load Cell is 5.0 Kg and Limit Type / Value is displacement / 180.0 mm.

In the hair treatment method, three bundles of hair are measured three times each in the wet state (PCL value, ACL value recording: unshampooed state), and then treated with the shampoo of each example and the comparative example, and measured in the wet state (PCL value, ACL value recording) (shampoo processing state)

The PCL and ACL values after shampoo and no shampoo for the above Examples and Comparative Examples were obtained, and the results were shown in Table 3 after comparing and evaluating the feeling of combing in the wet state with% change in PCL and ACL. The larger the value of the-% value, the better the combing feeling, and the test results show that the conditioning effect of the transparent composition of the present invention is superior.

The data value of the present invention is the average obtained by adding three values of the number of bundles three times for each bundle of Example 1 and Comparative Example 2 (capsule-containing transparent shampoo composition) of the present invention.
