Description

Shampoo compositions

Technical Field

The present disclosure relates to mild shampoo compositions comprising alkyl polyglucosides, sclerotium gum, and cationic polymers that deliver consumer desirable wet conditioning and sufficient viscosity for ease of use.

Background

Human hair can become dirty due to contact with the surrounding environment and sebum secreted by the scalp. The soiled hair has a dirty feel and an unattractive appearance. Application and washing of soiled hair with a shampoo composition can restore the hair to a clean and attractive appearance by removing oil and other dirt from the hair. Known shampoo compositions typically utilize anionic surfactants to remove oil and dirt from hair. However, shampoos containing anionic surfactants can lead to a number of undesirable characteristics, such as poor hair feel quality. Cationic polymers are commonly used in anionic surfactant cleaning compositions to provide moisturization and wet-straightening of hair. Nonionic surfactants are known to be mild to the skin, but are also known to be difficult to use in combination with charged polymers (cationic polymers) that result in unstable compositions. In addition, nonionic surfactant systems are typically thin (low viscosity), and thickening polymers may be required to increase viscosity to prevent the solution from dripping from the consumer's hand prior to application to hair. However, the combination of cationic polymers and commonly used thickeners such as guar gum generally results in unstable compositions. Surprisingly, it has been found that a small sclerotium gum having a unique triple helix structure is capable of stabilizing cationic polymers to obtain a single phase stable cleaning composition that delivers a range of desirable wet conditioning benefits and desirable viscosities.

It is desirable to have a shampoo composition that cleans without the use of anionic surfactants and also results in good in-use physical characteristics while also delivering the desired hair benefits. Surprisingly, it has been found that shampoo compositions comprising the nonionic surfactant alkyl polyglucoside, sclerotium gum and cationic polymer are phase stable and deliver sufficient viscosity for consumer desired wet conditioning and ease of use.

Cationic starch polymers

Suitable cationic polymers may also be water-soluble cationic modified starch polymers. As used herein, the term "cationically modified starch" refers to a starch to which cationic groups are added before degrading the starch to have a smaller molecular weight, or to which cationic groups are added after modifying the starch to obtain the desired molecular weight. The definition of the term "cationically modified starch" also includes amphiprotic modified starches. The term "amphiphilically modified starch" refers to starch hydrolysates to which cationic and anionic groups are added.

The shampoo compositions described herein may comprise in the range of from 0.01% to 10%, and/or from 0.05% to 5% by weight of the composition of the cationically modified starch polymer.

The cationically modified starch polymers disclosed herein have a bound nitrogen percentage of from 0.5% to 4%.

The cationic modified starch polymer may have a molecular weight of 850,000g/mol to 15,000,000g/mol, and 900,000g/mol to 5,000,000 g/mol.

The cationic modified starch polymer may have a charge density of from 0.2meq/g to 5meq/g, and from 0.2meq/g to 2 meq/g. Chemical modifications to achieve such charge densities may include adding amino and/or ammonium groups to the starch molecule. Non-limiting examples of such ammonium groups may include substituents such as hydroxypropyl trimethylammonium chloride, trimethylhydroxypropyl ammonium chloride, dimethyl stearyl hydroxypropyl ammonium chloride, and dimethyl dodecyl hydroxypropyl ammonium chloride. Additional details are described in Solarek, d.b., cationic Starches in Modified Starches: properties and Uses (Wurzburg, o.b. editions, CRC Press, inc., boca Raton, fla.1986, pages 113-125, which are incorporated herein by reference) cationic groups may be added to the starch before it is degraded to have a smaller molecular weight, or cationic groups may be added to the starch after such modification.

The cationic modified starch polymer may have a degree of substitution of cationic groups of 0.2 to 2.5. As used herein, the "degree of substitution" of a cationically modified starch polymer is an average measure of the number of hydroxyl groups on each anhydroglucose unit derived from a substituent. Since each anhydroglucose unit has three hydroxyl groups that can be substituted, the maximum possible degree of substitution is 3. The substitution degree is expressed as moles of substituents per mole of anhydroglucose unit, on a molar average. Proton nuclear magnetic resonance spectroscopy (a "proton nuclear magnetic resonance spectroscopy" as is well known in the art can be used " ¹ H NMR ") method to determine the degree of substitution. Suitable for ¹ H NMR techniques include those described in "Observation on NMR Spectra of Starches in Dimethyl Sulfoxide, iodine-completing, and Solvating in Water-Dimethyl Sulfoxide", qin-Ji Peng and Arthur S.Perlin, carbohydrate Research,160 (1987), 57-72; and "An Approach to the Structural Analysis of Oligosaccharides by NMR Spectroscopy", J.Howard Bradbury and J.Grant Collins, carbohydrate Research,71, (1979), 15-25.

The starch source prior to chemical modification may be selected from a variety of sources such as tubers, legumes, cereals and grains. For example, the starch source may include corn starch, wheat starch, rice starch, waxy corn starch, oat starch, tapioca starch, waxy barley starch, waxy rice starch, gluten rice starch, waxy rice starch, amylopectin starch, potato starch, tapioca starch, oat starch, sago starch, sweet rice starch, or mixtures thereof. Suitable cationically modified starch polymers may be selected from the group consisting of degraded cationic corn starch, cationic tapioca, cationic potato starch, and mixtures thereof. The cationic modified starch polymer is cationic corn starch and cationic cassava.

The starch may include one or more additional modifications either before degradation to have a smaller molecular weight or after modification to have a smaller molecular weight. For example, these modifications may include crosslinking, stabilization reactions, phosphorylation, and hydrolysis. The stability reaction may include alkylation and esterification.

The cationically modified starch polymer may be included in the shampoo composition in the form of hydrolyzed starch (e.g., acid, enzyme, or base degradation), oxidized starch (e.g., peroxide, peracid, hypochlorite, base, or any other oxidizing agent), physically/mechanically degraded starch (e.g., thermomechanical energy input via a processing device), or a combination thereof.

Starch is readily soluble in water and can form a substantially translucent solution in water. The transparency of the composition was measured by ultraviolet/visible ("UV/VIS") spectrophotometry, which uses a Gretag Macbeth colorimeter to determine the absorption or transmission of UV/VIS light by the sample. It has been shown that a light wavelength of 600nm is sufficient to characterize the transparency of the shampoo composition.

The cationic polymers described herein may also help repair damaged hair, particularly chemically treated hair, by providing an alternative hydrophobic F-layer. The extremely thin F-layer helps to seal moisture and prevent further damage while providing natural weatherability. Chemical treatments can damage the hair cuticle and cause its protective F-layer to delaminate. When the F-layer is peeled off, the hair becomes increasingly hydrophilic. It has been found that when lyotropic liquid crystals are applied to chemically treated hair, the hair becomes more hydrophobic and more natural in both look and feel. Without being bound by any theory, it is believed that the lyotropic liquid crystal complex forms a hydrophobic layer or film that covers the hair fibers and protects the hair as does the natural F-layer. The hydrophobic layer may restore the hair to a substantially original, healthier state. Lyotropic liquid crystals are formed by combining the synthetic cationic polymers described herein with the anionic detersive surfactant component of the aforementioned shampoo compositions. Synthetic cationic polymers have a relatively high charge density. It should be noted that some synthetic polymers having relatively high cationic charge densities do not form lyotropic liquid crystals, mainly due to their unusual linear charge density. Such synthetic cationic polymers are described in PCT patent application WO 94/06403, the disclosure of which is incorporated by reference. The synthetic polymers described herein may be formulated in stable shampoo compositions that provide improved conditioning performance for damaged hair.

The lyotropic liquid crystalline cationic synthetic polymer has a cationic charge density of from 2meq/gm to 7meq/gm, and/or from 3meq/gm to 7meq/gm, and/or from 4meq/gm to 7 meq/gm.

Cationic synthetic polymers that provide enhanced conditioning and benefit agent deposition without the need to form lyotropic liquid crystals can have cationic charge densities of 0.7meq/gm to 7meq/gm, and/or 0.8meq/gm to 5meq/gm, and/or 1.0meq/gm to 3 meq/gm. The polymer also has an m.wt. of 1,000 to 5,000,000g/mol, 10,000 to 2,000,000g/mol, 100,000 to 2,000,000 g/mol.

The use of dyes can help distinguish the coacervate phase from other insoluble phases dispersed in the composition. Additional details of the use of cationic polymers and coacervates are disclosed in U.S. patent No. 9,272,164, which is incorporated by reference.

First, a compact pH meter was calibrated Mettler Toledo Seven. This is done by starting the pH meter and waiting 30 seconds. The electrode is then removed from the storage solution, rinsed with distilled water, and wiped with a scientific cleaning wipe such asThe electrodes were carefully wiped. The electrodes were immersed in pH 4 buffer and the calibration button was pressed. Wait until the pH icon stops flashing and press the calibration button again. The electrodes were rinsed with distilled water and carefully wiped with a scientific cleaning wipe. The electrodes were then immersed in pH7 buffer and the calibration button was pressed again. Wait until the pH icon stops flashing and press the calibration button a third time. The electrodes were rinsed with distilled water and carefully wiped with a scientific cleaning wipe. The electrode was then immersed in pH 10 buffer and the calibration button was pressed a third time. Wait until the pH icon stops flashing and press the measurement button. The electrodes were rinsed with distilled water and carefully wiped with a scientific cleaning wipe.

The electrodes are immersed in the test sample and the read button is pressed. Wait until the pH icon stops flashing and record the value.

C. Appearance method

After the batch process is completed, the batch is first transferred to a storage vessel. Next, the sample batch was placed in a glass vial. Again, the samples were visually inspected. If the background is clearly visible, the appearance is recorded as transparent. If the background is visible but distorted or blurred, the recording is semi-transparent. If the background cannot be seen, the record is opaque.

D. Phase stabilization method

After the batch process is completed, the batch is first transferred to a storage vessel. Next, the sample batch was placed in a glass vial. Again, the samples were visually inspected. If the sample is homogeneous, it is recorded as one phase. If the sample has two or more distinct phases, phase separation is recorded as including the number of phases present. The different phases are visually different (blurring, color, texture changes). These different phases settle to the bottom, are on top, or are suspended.

E. Hair cluster assessment

This method describes how to evaluate the finished product on the hair switches. First, the hair was moistened for 15 seconds. Next, applying a shampoo to the hair switches; 0.1g shampoo per gram hair. The hair was then evaluated throughout the wash for different attributes of shampoo performance. The hair shampoo was rubbed with both hands for 30 seconds. During these 30 seconds, the following items were evaluated.

1. ) Foaming speed: assessment of how fast foam is produced (scale: 0=slow to 10=fast)

2. ) Foam amount: visual assessment of how much foam is produced (scale: 0 = low to 10 = high)

Next, water is placed on the hair switch to begin rinsing. Rinsing for 30 seconds. The rinse feel/rinse back drag was evaluated during rinsing. Once wetting begins, the hair is rubbed from top to bottom with moderate pressure between the thumb and two fingers using a non-dominant hand. The number of rubs is counted until a drag/skip is felt in the middle part of the hair cluster for 2 consecutive rubs. The rub number was recorded as a rinse reverse drag. The rubbing should be at a rate of 1 rub per second (scale: 1 = fast rinse/clean feel to 20 = slow rinse/dirty feel).

After 30 seconds of rinsing, the hair was rubbed from top to bottom with moderate pressure between thumb and two fingers from using a non-dominant hand to remove the entering water. The hair switches were repeatedly rubbed and evaluated for a clean feel of hair. This was recorded as a post-rinse-clean feel (scale: 0=low/dirty to 10=high/clean).

F. Bubble foaming method

First, water is turned on to allow it to reach the desired temperature of 37.5-38 ℃. Next, the foam was fluffed and wetted under water. Shampoo was applied to the top of the puff in a circular motion. The puff and the foamed product were then moved on top of the beaker. Next, the puff was pressed 10 times in a half turn forward direction. The pressing was repeated and pressed 10 times in the half turn backward direction. Finally, the puff is extruded to extrude all of the remaining foam. The amount of foam generated in the beaker was measured.

G. Measuring cylinder foaming method-foam volume

100ml of water was placed in a 1,000ml graduated cylinder. Then 0.5g of shampoo was added. The graduated cylinder was placed on a rotating device. The cylinder was rotated 25 full revolutions at a rate of 10 revolutions per 18 seconds to produce foam and stopped in a horizontal vertical position. A timer was set to allow 15 seconds of drainage. After 15 seconds, the foam volume was measured by recording the foam height (to the nearest 10ml mark), including any water drained to the bottom, on top of which the foam was floating.

H.Kruss foaming method

A KRUSS dynamic foam analyzer was used to evaluate the foam. Shampoo and water were added to device 1 (shampoo): 9 (water) dilution. The air passing through the chamber produces foam. The foaming speed, foam volume and bubble size were recorded.
