Description

Conditioning compositions and detergents for hair care

1. Field of the invention

The present invention relates to detergent conditioning compositions suitable for use in personal hygiene applications, which not only confer cleaning, wet untangling, dry untangling and hair handling properties, but are also relatively non-irritating and, of this way, suitable for use by young children and adults who have sensitive skin and eyes.

2. Description of the prior art

In the past, it was considered desirable to clean the hair and then condition it after cleaning. For many years, it was necessary to perform these acts in two separate stages. However, with the arrival of conditioning shampoos called "two in one", it became possible to condition and clean simultaneously. Unfortunately, many of these two-in-one conditioning shampoos and body cleansing creams have proven to be relatively irritating to the eyes and skin, and uncomfortable for use with children or sensitive adults. Therefore, an object of the present invention is to create a conditioning shampoo that has good cleansing ability, excellent conditioning properties and that has a low degree of eye and skin irritation.

An approach to provide hair conditioning benefits to a shampoo is described in US Patent No. 5,932,202, which discloses a composition composed of an ethoxylated alkyl sulfate surfactant, combined with an amphoteric surfactant; a cationic cellulosic polymer and a water-insoluble nonvolatile conditioning agent. Although this shampoo claims to have optimized the conditioning properties of its cellulosic polymer by selecting a particular surfactant combination, it is not known whether that surfactant combination is mild to the eyes and skin. In addition, cationic cellulosic polymers are often disadvantageously associated with leaving a "dirty" residue in the hair and skin. Additionally, it is necessary to use a suspending agent for the insoluble conditioning agent, to produce an aesthetically pleasing formulation. Typically, such formulations that require the use of a stabilizer are susceptible to separation and are capable of producing only opaque products.

As an alternative, guar gum derivatives have also been used in conditioning shampoos. US Patent No. 5,085,857 discloses compositions containing surfactants, guar gum derivatives and insoluble nonvolatile silicones. Like cationic cellulosic polymers, guar gum derivatives are also associated with leaving a "dirty" residue. In addition, these compositions also require a shear reduction polymer or an insoluble solid to enhance the stability of the composition.

WO-A-97/26860 and US-A-5,876,705 disclose conditioning shampoo compositions comprising a conditioning polymer and silicone.

EP-A-680743 discloses hair treatment compositions comprising vinyl pyrrolidone / vinylimidazolium copolymers.

It would be desirable to have a conditioning composition that not only confer cleansing, wet untangling, dry untangling, hair manipulation, but also had a low degree of eye and skin irritation. It would also be desirable to have said conditioning composition in a transparent or translucent formulation, aesthetically pleasing, without the need to add pearling agents, opacifying agents and suspending agents thereto.

The invention disclosed illustratively herein can be practically carried out suitably in the presence of any component, ingredient or stage that is not specifically disclosed herein. Various examples are set forth below to further illustrate the nature of the invention and how to carry it out. However, the invention should not be considered as limited to the details thereof.

Examples

All quantities of materials are given in parts by weight based on 100 parts of the overall formulation, unless otherwise indicated. The following test procedures were used in the following Examples:

1. Half Head Study: A girl, aged between 7 and 11, moistened her hair, which reached her shoulders, and then divided the hair through the center, to form two strands of hair. Both strands were fastened with a catcher. After unleashing a bunker, the girl washed the released hair using an adequate amount of “Johnson’s Kids No More Tangles Shampoo” available at Johnson & Johnson Consumer Companies, Inc., which contains Polyquaternium 10, polydimethyl cyclosiloxane and guar hydroxypropyltrimonium chloride. The amount of shampoo used depended on the respective type and length of the girl's hair. The girl applied the shampoo to the released hair, then washed it and cleared half of her head in a conventional manner. An assistant then recorded the formation of perceived foam, thickness and lightening capacity of the girl's hair on a scale of 1 to 5, with 5 being the maximum score.

After holding the freshly washed hair with the hair clipper, this procedure was repeated on the hair on the other side of the girl's head with an experimental formulation. The assistant then recorded the formation of perceived foam, thickness and rinse capacity of the girl's hair with respect to the same properties conferred by the commercial shampoo using the same scale.

After gently rubbing his entire head with a towel to dry it, while making sure that the hair on the sides of his head remained separate, an assistant combed the hair on each side of the girl's head with a wide barbed comb, and afterwards the attributes of wet hair perceived as wet detangling were evaluated, that is, ease of detangling the hair while it is wet, and wet feeling, that is, if the lightened hair seemed clean, with residue, or dry, on the scale described above, with the exception of "wet feeling", a score of "3" was the best and meant a clean feeling, while a score of 1 meant a dry feeling and 5 meant that a sensation had been detected. residue.

As the stylist dried the hair in one of the halves of the girl's head, the assistant dried the hair of the other half of the girl's head using a dryer with similar heating and airflow patterns. The stylist then combed the hair on each side of the girl's head using the same comb, to record the attributes of dry hair perceived by the dry hairstyle. The stylist also evaluated the dry softness, the dry gloss, the dry body, the dry static electricity and the dry feeling, that is, if the dry hair seemed clean, with residue, or dry, of the hair in each side of the girl's head, using the scale described above, with the exception that with respect to "dry feeling" a score of "3" was the best and meant a clean feeling, while a score of 1 meant a dry sensation and 5 meant that a residue had been detected.

2. Hair Conditioning Properties: The conditioning properties of the shampoos are determined by measuring the average energy and strength required to comb the hair in a wet and dry state after the hair has been washed with a particular shampoo formulation, according with the procedure outlined as follows:

a) Preparation of Hair Samples: human hair scalp weighing approximately 10-12 grams of virgin brown hair were prepared, and the end of the cuticle was attached with a union cable and hot melt glue. The cuticle end of the beam is placed in a clamp. The hair unfolds evenly across the entire width of the clip. The fusion glue is applied along the edge of the clip, joining the clip and the hair. Glue is applied to the inside of the clamp for additional reinforcement. A rubber band is applied to the outside of the clamp, to prevent the clamp clamps from separating. The glue is allowed to dry thoroughly. The hair is washed to remove contaminants, such as powder or shampoo remains, by washing the hair with a shampoo without conditioner available from The Procter and Gamble Company, under the trade name "Original Green Prell" and allowing it to air dry. Loose hair is removed. The tangles are removed combing the hair with a comb or conventional brush. The accumulated static charge is removed using a static electricity reducing gun.

The number of tests required for the test is equal to the number of formulations (and appropriate controls) in the test. The formulations are divided randomly, so that each product is applied to the hair at some point in time. Two applications of shampoo are required, each of which uses approximately 1 cc of shampoo composition. The hair is wetted thoroughly under running water at 100ºF (38ºC). Approximately 1 cm3 of a given shampoo composition is applied, evenly, from the top to the bottom of the hair. Using the fingers of both hands, the shampoo is rubbed into the hair for approximately 30 seconds, to produce foam. The hair is then rinsed thoroughly with running water at 100 ° F (38 ° C). The hair is washed again and rinsed using a second sample of 1 cm3 of product. The hair is then allowed to dry for 5 minutes.

The hairs are then suspended from a strong ring shelf, so that they hang freely and have several inches of slack between the end of the hairs and the top of the worktable.

b) Wet Detangling Energy: A Styling Force Device (DFP), which is a portable electromechanical instrument, which measures the amount of force or energy required to pass a comb through the hair, is held horizontally in one hand, and tangles are removed from the scalps starting at the bottom of the scalp and moving the DFP down. Each successive pass starts at a point higher than the previous pass. This measurement continues until the DFP passes freely through the entire length of the hair. Once all tangles have been removed, three passes from top to bottom complete the unraveling measurement. The energy accumulated to untangle the hair from the scalp is presented as wet detangling energy, in units of gram-second (g / s).

c) Wet Styling Force: Once the measurement of the detangling energy in all scalps is completed, the scalps are measured for the wet combing force. A detector, which is fixed to curling tongs, from which the heating element and other electronic components have been removed, measures the curling, or torsional force, of the curling tongs as the instrument moves through the hair . He

5 instrument is passed through untangled hair approximately 25 times. The styling force, expressed in grams, is the average force required to pass the comb through the untangled hair.

d) Energy for Dry Detangling: After the scalp has dried by blowing until they are no longer wet, the detangling procedure exposed in b is repeated using dry scalps.

10 e) Dry Styling Force: After the scalp has blow dried until they are no longer wet and the detangling energy has been determined, the styling procedure set out in c is repeated using the dry scalp.

3. Eye irritation: The potential for eye irritation is measured by an in vitro transepithelial permeability test ("PET"). Samples were also evaluated in vivo by a human eye irritation test.

15 PET Test: The expected eye irritation for a given formulation is measured according to the PET test, as set forth in Invittox Protocol Number 86 (May 1994). In general, the potential for eye irritation of a product can be assessed by determining its effect on the permeability of a cell layer, as assessed by fluorescein filtration through the layer. Monolayers of Madin-Darby canine kidney cells (MDCK) are developed until confluence in microporous inserts, in a 24-well plate that

20 contained medium or assay buffer, in the lower wells. The irritation potential of a product is assessed by measuring the damage to the permeability barrier in the cell monolayer after a 15 minute exposure to product dilutions. Barrier damage is assessed by the amount of sodium fluorescein that has been filtered through the lower well, after 30 minutes, as determined spectrophotometrically. Fluorescein filtration is drawn against the concentration of test material to determine EC50

25 (concentration of test material that causes 50% of the maximum filtration of the dye, that is, 50% damage to the permeability barrier).

Exposure of a layer of MDCK cells cultured on a microporous membrane to a test sample is a model for the first event that occurs when an irritant comes into contact with the eye. In vivo, the outermost layers of the corneal epithelium form a selectively permeable barrier, due to the presence of 30 strong junctions between the cells. After exposure to an irritant, strong bonds separate, thereby removing the permeability barrier. The fluid is embedded in the underlying layers of the epithelium and stroma, causing collagen lamellae to separate, resulting in opacity. The TEP assay measures the effect of an irritant on the degradation of strong bonds between cells in a layer of MCDK cells developed in a microporous insert. The damage is evaluated spectrophotometrically, measuring the amount of

35 marker dye (sodium fluorescein) that filters through the cell layer and the microporous membrane to the lower well. A TEP score of 2.2% or higher is considered to pass, a score of 1.78% to 2.19% is considered a limit and a score of 1.79% or less is considered a failure. The test results are presented in Table 7.

Human Eye Irritation Assay: Using a study design study of two (2) randomized cells, from

Double blind, one (1) drop of a sample (for example, a 10% dilution of a cleaning composition in water) at a temperature of approximately 38 ° C, was instilled in the eye of a subject. A new sterile disposable dropper bottle was used for each sample, and was discarded after use only in the eye of an individual. All instillations were performed by a researcher or a qualified technician.

Within 30 seconds, or as soon as possible after instillation, the subject was asked to rate the stinging sensation of the eye using the following criteria:

Itching

0 = Within normal limits

1 = Soft, very light

2 = Moderate

3 = Severe

After 15 minutes and 60 minutes after instillation, the subject was again asked to rate the sensation of stinging perceived in the eye. The data was collected from a balanced complete block experiment, and then analyzed statistically.

50 Example 1: Preparation of the Conditioning Composition

The following premixes were prepared: Premix A: 1.5 parts of benzophenone 4 were mixed with 3 parts of deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix B: 0.1 part of the dye was mixed with 10 parts of deionized water, at 22 ° C in a mixing vessel, until a homogeneous mixture was obtained.

5 Premix C: 3.5 parts of fragrance were mixed with 10 parts of PEG-80 sorbitan laurate at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix D: 0.5 parts of Quaternium 15 were mixed with 1 part of deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix E: 2 parts of citric acid were mixed with 8 parts of deionized water at 22 ° C, in a mixing vessel 10, until a homogeneous mixture was obtained.

Composition of the Formulation of Example 1:

35 parts of Polyquaternium 44 were combined with 300 parts of deionized water in a mixing vessel, until a homogeneous, transparent mixture was obtained. While the clear mixture was heating at a temperature of about 60 ° C to about 71 ° C, 10 parts of PEG distearate were added

15 150 thereto with mixing, until a homogeneous mixture was obtained. While the mixture was cooling to a temperature of 22 ° C, 10 parts of dimethicone copolyol and 5 parts of trimethylsilylammodimethicone were added thereto, with stirring, until the resulting mixture became clear.

The remaining surfactants were then added thereto with mixture: 55 parts of PEG-80 Sorbitan Laurato; 133 parts of cocamidopropyl betaine; 95 parts sodium trideceth sulfate; and 28.5 parts of lauranphodiacetate.

Then, 10 parts of glycerin were added thereto with mixing, the resulting mixture was stirred until it became clear with slight turbidity. Then 258 parts of water were added thereto to cool the mixture to a temperature below 40 ° C.

After the mixture reached a temperature below 40 ° C, Premixes A to D, followed by 1.8 parts of tetrasodium EDTA were added thereto, consecutively, with stirring. The pH was checked

25 and then adjusted from about 5.9 to about 6.2 with additional citric acid solution. The amounts of the ingredients used to make the composition of Example 1 are shown in Table 1 below.

This Example demonstrated that the formulation of Example 4, which contained a relatively high amount of

10 Polyquaternium 44, in combination with the mixture of trimethylsilylammodimethicone and dimethicone silicone copolyol, in an equivalent weight ratio, conferred relative, better or comparable properties, wet thickness, foam formation, rinse ability, wet detangling, sensation in wet, dry combing, dry softness, dry gloss, dry body, dry static electricity and dry feeling, than those conferred by commercial shampoo.

15 This Example further illustrates that compositions containing both Poliquaternium 44 and silicone conditioning agents were better than a similar composition containing only Poliquaternium 44, with respect to wet thickness, rinse ability, wet feeling, dry softness, gloss dry and static dry electricity.

Example 6: Wet Stripping Hairstyle Force

20 Samples of shampoo compositions prepared according to Examples 1-4 and the commercial shampoo NEW JOHNSON’S KIDS " No More Tangles " they were evaluated for combing strength for wet detangling, according to the procedure set forth above.

These results further illustrate that the formulations of the present invention, which contain a branched quaternary cationic polymer in combination with silicone polymers, demonstrated better performance than shampoos containing both guar-based and cellulosic conditioning polymers, together with silicones, as well as Similar shampoos containing a single branched quaternary cationic polymer, without a silicone conditioning agent. In this way, the combination of the branched quaternary cationic polymer together with the silicone polymers produced synergistically superior results.

Examples 7 and 8: Preparation of Conditioning Compositions

The following premixes were prepared:

Premix A: 1.5 parts of benzophenone 4 were mixed with 3 parts of deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix B: 0.1 part dye was mixed with 10 parts deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix C: 3.5 parts of fragrance were mixed with 10 parts of PEG-80 sorbitan laurate at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix D: 0.5 parts of Quaternium 15 were mixed with 1 part of deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Premix E: 2 parts of citric acid were mixed with 8 parts of deionized water at 22 ° C, in a mixing vessel, until a homogeneous mixture was obtained.

Composition of the Formulation of Examples 7 and 8:

3.2 parts of Polyquaternium 10 were combined with 300 parts of deionized water, in a mixing vessel, until a homogeneous mixture was obtained with no floating particles present. While the mixture was heated to a temperature of about 60 ° C to 71 ° C, 5 parts of PEG 150 distearate were added thereto, with mixing, until a homogeneous mixture was obtained. As the mixture cooled to a temperature of 22 ° C, the remaining ingredients were added with stirring between each addition, until the resulting mixture became homogeneous: 55 parts of PEG-80 Sorbitan Laurato; 133 parts of cocamidopropyl betaine; 5 parts dimethicone copolyol; 28.5 parts of lauranphodiacetate and 95 parts of sodium trideceth sulfate. After 10 parts of glycerin were added thereto with mixing, the resulting mixture was stirred until it became clear with slight turbidity. The remaining parts of water were then added thereto to cool the mixture to a temperature below 40 ° C.

After the mixture reached a temperature below 40 ° C, Premixes A to D, followed by 1.8 parts of tetrasodium EDTA and 5 parts of trimethylsilylammodimethicone, were added thereto consecutively, with stirring. The batch was mixed for 7 final minutes until it became homogeneous. The pH was then checked and adjusted from 5.8 to 6.2, with an additional citric acid solution.

This Example was repeated but Polyquaternium 10 was exchanged for an equivalent amount of guar hydroxypropyltrimonium chloride.

Composition of the Formulation of Example 9:

40 parts of Polyquaternium 44 were combined with 300 parts of deionized water, in a mixing vessel, until a homogeneous mixture was obtained with no floating particles present. While the mixture was heated to a temperature of 60 ° C to 71 ° C, 9 parts of PEG 150 distearate were added thereto with mixing, until a homogeneous mixture was obtained. As the mixture cooled to a temperature of 22 ° C, the remaining ingredients were added thereto with stirring between the addition of each ingredient, until each intermediate resulting from the mixture was homogeneous: 27.5 parts of PEG-80 Sorbitan Laurato; 3.75 parts of dimethicone copolyol; 28.5 parts of lauranphodiacetate; 10 parts glycerin; 66.5 parts of cocamidopropyl betaine;

25 27.5 parts of PEG-80 Sorbitán Laurato; 47.5 parts of sodium trideceth sulfate. Then the remaining water, 66.5 parts of cocamidopropyl betaine and 47.5 parts of sodium trideceth sulfate were added thereto to cool the mixture, and the resulting mixture was stirred until it became clear to slightly cloudy.

After the mixture reached a temperature below 40 ° C, Premixes A to D, followed by 1.8 parts of tetrasodium EDTA and 10 parts of dimethicone copolyol, were added thereto consecutively, with stirring. The batch was mixed for 7 final minutes until it became homogeneous. The pH was then checked and adjusted to approximately 6.9 -7.2 with an additional citric acid solution. The amounts of the ingredients used to prepare the composition of Example 9 are shown in Table 5 below.
