[0086] The hair care compositions according to the disclosure may be in various forms, such as in the form of a liquid, cream, liquid-gel, liquid-cream, gel, lotion, or paste. In various embodiments, the hair care composition is a rinse-off composition, i.e. a composition which is intended to be applied to the hair, left on for a period of time and subsequently rinsed off the hair.

HAIR TREATMENT METHODS

[0087] As described herein, the hair care compositions can be used to treat the hair, for example before or after shampooing the hair. In certain embodiments, the hair care composition can be applied simultaneously with shampooing the hair. In other embodiments, the hair treatment composition can also be applied to the hair as a standalone treatment, i.e. without shampooing the hair before or after the treatment is applied.

[0088] In various embodiments, the hair treatment composition described herein may be first applied to the hair, then the hair is optionally rinsed, followed by shampooing the hair. In other embodiments, the hair care composition can be applied to the hair after the hair is washed, before or after the shampoo is washed out of the hair.

[0089] As used herein, the hair treatment compositions can be applied to the hair "before" the hair is rinsed and/or shampooed, such as about one minute before, up to 2 minutes before, up to 3 minutes before , up to 4 minutes before, up to 5 minutes before, up to 10 minutes before, up to 20 minutes before, up to 30 minutes before, up to 1 hour before, up to 2 hours before, up to 6 hours before, up to 12 hours before, or up to 24 hours before, for example.

[0090] As used herein, the treatment compositions can be applied to the hair “after” the hair is shampooed, such as less than one minute later, up to 2 minutes later, up to 3 minutes later, up to 4 minutes later, up to About 5 minutes later Up to about 10 minutes later Up to about 20 minutes later Up to about 30 minutes later Up to about 1 hour later Up to about 2 hours later Up to about 6 hours later Up to about 12 hours later or up to about 24 hours later, for example.

[0091] In various exemplary methods, the hair care composition can be applied to the hair and after an optional rest time (no-rinse time) on the hair fibers, for example, ranging from a few seconds to about 60 minutes, as of about 1 minute to about 10 minutes, 1 minute to about 5 minutes, or 1 minute to about 3 minutes, the hair fibers can be washed.

[0092] In certain embodiments, it may be beneficial to heat the hair while the hair care composition is resting on the hair fibers. For example, the temperature during hair treatment methods can range from room temperature to 80°C, such as from room temperature to 60°C, or from room temperature to 40°C.

[0093] It has been discovered that the application of the hair care composition described herein can provide strengthening and/or protection to the hair fiber so as to prevent or minimize damage to the hair fiber in at least some embodiments.

[0094] It should be understood that any degree of protection and/or strengthening and/or minimization of damage can be transmitted to the hair fiber without limitation. Furthermore, embodiments which do not impart fiber strength and/or protection and/or minimization of damage to the hair fiber are also intended to be within the scope of the disclosure.

[0095] It should be understood that, as used herein, the terms “the / the”, “an” or “an” mean “at least one” and should not be limited to “only one”, unless it is explicitly stated the opposite. Thus, for example, reference to "a portion" includes examples with two or more such portions, unless the context clearly indicates otherwise.

[0096] Unless expressly stated otherwise, it is in no way intended that any method set forth herein be construed as requiring its steps to be performed in a particular order. Accordingly, when a method claim does not actually recite an order to be followed by its steps or it is not otherwise specified in the claims or descriptions that the steps are to be limited to a specific order, it is in no way intended that any order particular is inferred.

[0097] While various features, elements, or steps of particular embodiments may be disclosed using the transition phrase "comprising", it is to be understood that alternative embodiments, including those that may be described using the transition phrases "consisting of ” or “consisting essentially of” are implied. Thus, for example, implied alternative embodiments of a method comprising A + B + C include embodiments in which a method consists of A + B + C and embodiments in which a method consists essentially of A + B + C. As described, the phrase "at least one of A, B and C" is intended to include "at least one A or at least one B or at least one C" and is also intended to include "at least one A and at least one B and at least one C.”

[0098] All ranges and quantities provided herein are intended to include subranges and quantities using any disclosed point as an endpoint. Thus, a range of “1% to 10%, such as 2% to 8%, such as 3% to 5%”, is intended to encompass ranges of “1% to 8%”, “1% to 5%”, “2% to 10%” and so on. All numbers, values, ranges, etc. should be modified by the term “about,” whether or not it is expressly indicated. Likewise, a given range of "about 1% to 10%" intends the term "about" to modify the 1% and 10% endpoints.

[0099] Notwithstanding the ranges and numerical parameters that establish the broad scope of the disclosure are approximations, unless otherwise indicated, the numerical values set forth in the specific examples are reported as accurately as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in its respective test measurements. The following example serves to illustrate embodiments of the present disclosure, without, however, being limiting in nature.

[00100] It will be apparent to those skilled in the art that various modifications and variations can be made to the delivery system, composition and methods of the invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention, provided that they fall within the scope of the appended claims and their equivalents.

EXAMPLES

[00101] The amounts of ingredients in the composition/formulations described below are expressed in % by weight, based on the total weight of the composition, unless otherwise indicated.

EXAMPLE 1: COMPOSITIONS FOR HAIR TREATMENT

[00102] The compositions of Examples 1A-1F were prepared for use as rinse-off hair treatment compositions. The compositions were prepared by combining different concentrations of fatty alcohol, fragrance and vitamins. TABLE 1

[00103] The following are examples of methods or processes for treating hair with hair care compositions in accordance with the disclosure.

EXAMPLE 2: METHOD FOR PREVENTION AND REPAIR OF SPLIT ENDS

[00104] Twelve strands of previously damaged hair were pre-cleaned with 10% sodium lauryl ether sulfate solution (SLES) for 1 minute and then rinsed with running water. The locks were dried in a standardized environment at 50 ± 5% relative humidity and 20 ± 2 °C for 24 hours. The initial number of split ends was determined in 100 hair fibers per strand.

[00105] Six control strands were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the control locks.

[00106] Six treatment wicks were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the treatment locks. Approximately 1 g of the hair care composition of Example 1A was applied to each lock, rubbed in for 60 seconds, allowed to stand for 3 minutes, and rinsed for 30 seconds under running water. Excess water was removed from the locks being treated.

[00107] The twelve locks were manually combed 5 times to detangle them and placed in an automatic hair comb. Each strand was combed 500 times at 40°C, 25 RPM, and subsequently combed another 500 times at 27°C, 25 RPM. This process was repeated 5 times.

[00108] Subsequently, the final number of split ends in 100 hair fibers per strand was determined. The results of the initial and final number of split ends are presented in Table 2 and in Figure 1. TABLE 2

[00109] According to the results in Table 2 and Figure 1, the control locks showed a significantly greater number of split ends after styling compared to before, and the treated locks showed the same or fewer split ends after styling in comparison with before. This confirms that the hair care composition according to the disclosure effectively prevents split ends (100%) and also repairs previously existing split ends.

EXAMPLE 3: METHOD TO REDUCE HAIR BREAKAGE

[00110] Twelve locks of hair were pre-cleaned with 10% sodium lauryl ether sulfate solution (SLES) for 1 minute and then rinsed with running water. The locks were dried in a standardized environment at 50 ± 5% relative humidity and 20 ± 2 °C for 24 hours.

[00111] Six control locks were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the control locks.

[00112] Six treatment strands were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the locks being treated. Approximately 1g of the hair care composition of Example 1A was applied to each lock, rubbed in for 60 seconds, allowed to stand for 3 minutes and rinsed for 30 seconds under running water. Excess water was removed from the treatment locks.

[00113] The twelve locks were manually combed 5 times to detangle them and placed in an automatic hair comb. Each lock was combed 800 times at 80 °C, 25 rpm.

[00114] The process of wetting the locks, washing with shampoo, rinsing, treating the treatment locks, manually combing and combing the locks 800 times in an Automated Hair Comb was carried out for 20 cycles on each lock. After the end of 20 cycles, the number of broken hair fibers in each strand was counted. The results are presented in Table 3 and in Figure 2. TABLE 3

[00115] According to the results in Table 3 and Figure 2, the control locks showed a significantly higher number of broken hair fibers after washing and styling, and the treated locks showed a significantly lower number of broken hair fibers after washing and comb it. This confirms that the hair care composition according to the disclosure effectively and significantly reduces hair breakage (91%).

EXAMPLE 4: METHOD TO IMPROVE HAIR COMBABILITY

[00116] Twelve locks of hair were pre-cleaned with 10% sodium lauryl ether sulfate solution (SLES) for 1 minute and then rinsed with running water. The locks were dried in a standardized environment at 50 ± 5% relative humidity and 20 ± 2 °C for 24 hours. All twelve dry locks were chemically treated with a guanidine hair straightening composition and process, shampooed and subsequently chemically treated with a standard hair bleaching composition and process and then shampooed.

[00117] Six control strands were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the control locks.

[00118] Six treatment wicks were wetted with water for 20 seconds and excess water was removed. Approximately 1 g of a neutral shampoo (without conditioning agents) was applied to each lock, rubbed for 60 seconds, left to rest for 1 minute and rinsed for 30 seconds under running water. Excess water was removed from the treatment locks. Approximately 1g of the hair care composition of Example 1A was applied to each lock, rubbed in for 60 seconds, allowed to stand for 3 minutes and rinsed for 30 seconds under running water. Excess water was removed from the treatment locks.

[00119] Each of the twelve locks was manually massaged with a comb to remove knots and then fixed to an EMIC DL-500 test device (TESC 3.01 software) with a fixed support with a standard comb attached to a cell of load previously calibrated to 20.0 N. The wicks were inserted through the teeth of the comb attached to the base of the device under the motor shaft, which is moved vertically at a constant speed of 300 mm/minute. The necessary wet combing energy was thus determined for each lock, the results of which are shown in Table 4 and Figure 3. TABLE 4

[00120] According to the results of Table 4 and Figure 3, the control locks showed no significant difference in combing energy values compared to the baseline. However, treatment locks demonstrated surprisingly significantly lower combing energy values when compared to baseline. This confirms that the hair care composition according to the disclosure effectively and significantly reduces the energy needed to comb the hair (82%). This result will lead to increased hair fiber conditioning and hair softness.
