Description

Technical Field

[0001] This disclosure generally relates to mild shampoo compositions that do not contain ionic surfactants and that use high molecular weight cationic guar polymers for cleaning and conditioning to increase the beneficial conditioning effects for consumers. Background Technology

[0002] Human hair becomes dirty due to contact with the surrounding environment and sebum secreted by the scalp. Dirty hair feels grimy and has an unattractive appearance. Applying and washing dirty hair with a shampoo composition can restore it to a clean and attractive appearance by removing oil and other dirt. Known shampoo compositions typically remove oil and dirt from hair by including anionic surfactants. However, shampoos containing anionic surfactants such as sodium lauryl sulfate and sodium lauryl polyoxyethylene ether sulfate can exhibit many undesirable characteristics, such as a poor hair feel and dryness of hair and skin after washing. Shampoos containing anionic surfactants also face poor consumer acceptance due to this abrasiveness. Cationic polymers are often used in anionic surfactant cleansing compositions to provide moisturizing and wet-smoothing effects on hair. Nonionic surfactants are known to be gentle on the skin, but they are also known to be difficult to combine with charged polymers. In addition, nonionic surfactant systems are typically thin (low viscosity) and often require thickening polymers to increase viscosity and prevent the solution from dripping from the consumer before being applied to the hair. Common thickening polymers used in nonionic surfactant systems include nonionic polymers such as guar gum. However, these nonionic polymers do not provide the beneficial hair effects, such as conditioning, that consumers expect. There is a desire for a shampoo composition that cleanses without the use of anionic surfactants and also has good physical properties for use, while delivering the desired beneficial hair effects. Surprisingly, it has been found that shampoo compositions comprising a nonionic surfactant and cationic guar gum are phase-stable and deliver the desired viscosity for use and the beneficial effects of cleansing, moisturizing, and smoothing hair (conditioning benefits), wherein the cationic guar gum has a weight-average molecular weight of about 800,000 g / mol to about 5,000,000 g / mol and a charge density of about 0.1 meg / g to about 2.5 meg / g. Summary of the Invention

[0003] The present invention provides a shampoo composition comprising: about 8% to about 35% decyl glucoside; less than 1% surfactant selected from sodium alkyl sulfate, sodium cocoyl hydroxyethyl sulfonate, sodium lauroyl sarcosinate, cocamidopropyl betaine, sodium lauroamphoacetate, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, and mixtures thereof; about 0.4% to about 1.2% cationic guar polymer having a weight-average molecular weight of about 800,000 g / mol to about 5,000,000 g / mol and a charge density of about 0.1 meg / g to about 2.5 meg / g; wherein the shampoo composition has a viscosity of about 300 cps to 8,000 cps.

This product maintains phase stability and good viscosity, and continuously provides the beneficial effects of cleansing, moisturizing, and smoothing hair.

[0017] In addition, the shampoo contains small amounts of ionic surfactants, including sodium alkyl sulfate, sodium cocoyl hydroxyethyl sulfonate, sodium lauroyl sarcosinate, cocamidopropyl betaine, sodium lauroamphoacetate, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, and mixtures thereof. The amount of the ionic surfactant is from about 0% by weight to about 1% by weight, from about 0% by weight to about 0.5% by weight, from about 0.1% by weight to about 0.2% by weight, and alternatively from about 0% by weight to about 0.3% by weight.

[0018] The shampoo composition has a viscosity of about 300 cps to 8,000 cps. The viscosity may also be about 500 cps to about 7,000 cps, about 500 to about 6,000 cps, about 800 to about 4,000 cps, or any combination thereof.

[0019] Nonionic surfactants

The nonionic surfactant may be a polyglucoside selected from the group consisting of: decyl glucoside, lauryl glucoside, octyl glucoside, capryloyl glucoside, capryloyl / capryloyl glucoside, undecyl glucoside, cocoyl glucoside, myristyl glucoside, hexadecyl glucoside, octadecyl glucoside, arachidyl glucoside, cetyl glucoside, cetearyl glucoside, isostearyl glucoside, and mixtures thereof. The nonionic surfactant may be decyl glucoside. The shampoo composition may contain about 8% to about 30% by weight, about 8% to about 25% by weight, or about 7% to about 20% by weight of a nonionic surfactant.

[0021] Nonionic surfactants can be alkyl polyglucosides having the following structures:

Guar gum used to prepare these guar gum derivatives is typically obtained in the form of naturally occurring material derived from the seeds of the guar gum plant. The guar gum molecule itself is a linear mannan branched by mono-galactose units on alternating mannose units at regular intervals. The mannose units are linked to each other via β(1-4) glycosidic bonds. Galactose branching occurs via α(1-6) bonds. Cationic derivatives of guar gum are obtained by the reaction between the hydroxyl groups of the polygalactomannan and a reactive quaternary ammonium compound. The degree of substitution of the cationic groups on the guar gum structure should be sufficient to provide the desired cationic charge density described above.

[0029] Cationic guar polymers may have a weight-average molecular weight of about 800,000 g / mol to about 5,000,000 g / mol, about 800,000 g / mol to about 3,000,000 g / mol, about 900,000 g / mol to about 3,000,000 g / mol, about 800,000 g / mol to about 2,500,000 g / mol, and / or about 900,000 g / mol to about 2,500,000 g / mol.

Unless the organic solvent is additionally incorporated into the composition as a trace component of other necessary or optional components, the liquid carrier may be water with a minimal or no significant concentration of the organic solvent. Suitable organic solvents may comprise aqueous solutions of lower alkyl alcohols and polyols. Available lower alkyl alcohols include monohydric alcohols having 1 to 6 carbon atoms, such as ethanol and isopropanol. Exemplary polyols include propylene glycol, hexanediol, glycerol, and propanediol.

[0051] Siloxane emulsion

[0052] The hair care composition may comprise, by weight, one or more siloxane polymers in amounts of about 0% to about 10%, about 0.1% to about 8%, about 0.1% to about 5%, about 0.1% to about 4%, about 0.1% to about 3%, about 0.1% to about 2%, about 0.1% to about 1.5%, and / or about 0.1% to about 1.2%. The siloxane polymer may be added to the hair care composition as an aqueous pre-emulsion. The siloxane pre-emulsion may comprise one or more siloxane polymers and an emulsification system. The siloxane polymer content in the siloxane pre-emulsion may be about 10% by weight to about 70% by weight, or about 15% by weight to about 60% by weight, or about 18% by weight to about 50% by weight.

[0054] The particle size of one or more siloxanes can be measured by dynamic light scattering (DLS). The Malvern Zetasizer Nano ZEN3600 system, using a 633nm helium-neon laser, can be used for measurements at 25°C.

[0055] The autocorrelation function can be analyzed using the Zetasizer software provided by Malvern Instruments, which uses the Stokes-Einstein formula to determine the effective hydrodynamic radius:

[0056]

[0057] Where k B Where η is the Boltzmann constant, T is the absolute temperature, η is the viscosity of the medium, D is the average diffusion coefficient of the scattering substance, and R is the hydrodynamic radius of the particle.

[0058] Particle size (i.e., hydrodynamic radius) can be obtained by relating the observed speckle pattern due to Brownian motion to the solved Stokes-Einstein equation, which relates particle size to the measured diffusion constant, as is known in the art.

[0059] For each sample, three measurements can be performed, and the Z-mean can be reported as particle size.

Then immerse the electrode in pH 10 buffer and press the calibration button a third time. Wait until the pH icon stops flashing, then press the measurement button. Rinse the electrode with distilled water and carefully wipe it with a scientific cleaning agent.

[0188] Immerse the electrode in the test sample and press the read button. Wait until the pH icon stops flashing, and then record the value.

[0189] C. Appearance Method

[0190] After batch processing is complete, first transfer the batch material to a storage container. Next, place the sample batch material in glass vials. Then, visually inspect the samples. If the background is clearly visible, record the appearance as transparent. If the background is visible but distorted or blurry, record it as translucent. If the background is not visible, record it as opaque.

[0191] D. Phase stability method

[0192] After batch processing, the batch is first transferred to a storage container. Next, the sample batch is placed in glass vials. Then, the sample is visually inspected. If the sample is homogeneous, it is recorded as one phase. If the sample has two or more distinct phases, it is recorded as phase separation including the number of phases present. Different phases are visually distinct (blurred, colored, textured). These distinct phases may settle to the bottom, remain on top, or be suspended.

[0193] E. Hair cluster assessment

[0194] This method describes how to evaluate the performance of a shampoo composition on a hair tuft. First, wet the hair for 15 seconds. Second, apply shampoo to the hair tuft; 0.1g of shampoo per gram of hair. Then, evaluate the different properties of the shampoo performance on the hair tuft throughout the wash. Rub the hair tuft with your hands for 30 seconds. During these 30-second intervals, evaluate the following:

[0195] 1.) Foaming speed: An assessment of how quickly foam is produced (scale: 0 = slow to 10 = fast)

[0196] 2.) Foam Amount: A visual assessment of how much foam is produced (scale: 0 = low to 10 = high).

[0197] Next, apply water to the hair tuft to begin rinsing. Rinse for 30 seconds. During rinsing, assess the rinsing feel / rinsing back drag. Once wetting has begun, use your non-dominant hand to rub the hair from top to bottom with moderate pressure between your thumb and two fingers. Count the number of rubs until you feel a drag / skip in the middle of the tuft, continuing for 2 consecutive rubs. Record this number of rubs as the rinsing back drag. The rubbing should be at a rate of 1 rub per second (scale: 1 = fast rinsing / cleaning feel to 20 = slow rinsing / dirty feel).

[0198] After rinsing for 30 seconds, use your non-dominant hand to rub the hair from top to bottom with moderate pressure between your thumb and two fingers to remove any trapped water. Repeat rubbing the hair tufts and assess how clean the hair feels. Record this as the post-rinse cleanliness feeling (scale: 0 = low / dirty to 10 = high / clean).

[0199] F. Method for making cream puffs

[0200] First, turn on the water to allow it to reach the desired temperature of 37.5-38°C. Next, fluff the foam and wet it underwater. Apply shampoo to the top of the puff in a circular motion. Then move the puff and foaming product to the top of the beaker. Next, squeeze the puff 10 times in a half-circle forward direction. Repeat the squeezing and squeeze 10 times in a half-circle backward direction. Finally, squeeze the puff to expel all remaining foam. Measure the amount of foam produced in the beaker.

[0201] G. Measuring cylinder foaming method – foam volume

[0202] Add 100ml of water to a 1000ml graduated measuring cylinder. Then add 0.5g of shampoo. Place the graduated cylinder on a rotating device. Rotate the cylinder 25 full revolutions at a rate of approximately 10 revolutions every 18 seconds to create foam, and stop at a vertical position with the cylinder horizontal. Set a timer to allow 15 seconds of drainage. After 15 seconds, measure the foam volume by recording the foam height (accurate to 10ml marks) (including any water drained to the bottom, with foam floating on top).

[0203] H.Kruss's foaming method

[0204] The KRUSS dynamic foam analyzer was used to evaluate the foam. Shampoo and water were added to a 1 (shampoo): 9 (water) dilution. Foam was generated by passing air through the chamber. Foaming rate, foam volume, and bubble size were recorded.
