Description

NEW STYLING COMPOSITION TO OFFER DIFFERENT ADVANTAGEOUS PROPERTIES TO HAIR

The present disclosure relates to compositions and methods for styling and caring for hair. The disclosed compositions improve the look and feel of hair. The disclosure also relates to methods of using the compositions.

CONTEXT

Consumers desire new and improved styling compositions that can provide visible curl definition and frizz control in high humidity environments, while providing various additional beneficial properties to hair such as good curl definition, curl hold , hydration, softness and smoothness of the hair.

The present invention aims to provide a composition containing a chelating agent and sugar that provides curl definition, enhanced frizz control and good feel to the hair, even in high humidity environments.

SUMMARY

The present disclosure relates to hair styling compositions, which may provide beneficial effects, such as curl definition, to hair. The compositions are optionally leave-in styling compositions. The compositions may include (a) at least one chelating agent; (b) at least one sugar; and (c) at least one cosmetically acceptable solvent, in which the pH of the composition is between 3 and 9.

The present disclosure relates to a process for styling and/or caring for hair comprising the application to the hair of a composition comprising: (a) at least one chelating agent (b) at least one sugar (c) at least one solvent cosmetically acceptable.

The present disclosure relates to a hair styling composition, comprising: (a) at least one chelating agent (b) at least one cosmetically acceptable solvent, wherein the chelating agent is from about 1% to about 7% of the composition total.

Chelating agents are typically used in hair products to bind metal ions present in water or product to improve stability and/or performance. The requester was surprised to discover a good loop definition resulting from a chelating agent.

In particular, it was surprisingly and unexpectedly discovered that the combination of chelating agent and sugar provides the complete results of curl definition, enhanced frizz control and good feel to the hair, while these components alone only provide some benefits, but not all.

In other words, the inventors of the present application have developed a new and improved styling composition for curly hair that is resistant to high humidity conditions.

Examples

The following examples are intended to be non-limiting and explanatory in nature only. In the Examples, unless otherwise indicated, the quantities are expressed as a percentage by weight (% by weight) of active ingredients, relative to the total weight of the composition.

Example 1 - Simplex Assay for Chelating Agent

In order to demonstrate the beneficial effects of chelating agents according to the disclosure on curly hair, the following water compositions with varying chelating agents (B-E) and a comparative composition without chelating agent (A) were prepared.

[Table 1] Chelating agent compositions

Sample Chelating agent % of chelating agent Water HAS Water only 0% 100% B Trisodium HEDTA 5% 95% VS Trisodium Ethylenediamine Disuccinate 5% 95% D Disodium cocoamphodiacetate 5% 95% E Tetrasodium Glutamate Diacetate 5% 95%

Each of the compositions A-E was tested on five strands of natural curly hair. Each section of hair was first washed with a commercially available shampoo and detangled. The samples were then air-dried and sprayed with water five times per wick. While the strands were still damp, equal amounts of a test composition were applied to each strand of hair and then styled. After the strands were air dried, they were placed in a humidity chamber at 80% relative humidity at 25 C for one hour.

After one hour in the humidity chamber, the treated strands were qualitatively assessed for curl definition, frizz control and sensory profile. A rating of 1 to 5 was given for frizz control and curl definition, where 1 represented the least amount of frizz control/curl definition and 5 represented the most frizz control/curl definition. The sensory profile was determined by manually palpating each strand. A description of the term coated was given when the hair had a coated feel which was a neutral description.

The following Table 2 shows the results of the assessment and the scores of the visual properties of the hair strands treated with the test compositions.

As shown in Tables 1 and 2, various chelating agents alone provide excellent curl definition and frizz control compared to strands treated without a chelating agent. Locks with chelating agent applied had a coated feel compared to locks without chelating agent.

Example 2. Tests on the combination of sugar and chelating agent

In order to demonstrate the beneficial effects of the chelating agent in combination with various sugars according to the disclosure on curly hair, the following water compositions with different chelating agent/sugar combinations (G-L) and a comparative composition of F, N and V were prepared. The tests were carried out in a pH range between 3 and 9.

[Table 3] Sugar and chelating agent combinations Sample Sugar at 1 % Chelating agent at 0.5 % Water F nothing nothing 100 % G Glucose
Disodium cocoamphodiacetate 98.5 % H Erythritol
(Fisher) Disodium cocoamphodiacetate 98.5 % I Glucosamine HCl Disodium cocoamphodiacetate 98.5 % J Hydrogenated starch hydrolyzate Disodium cocoamphodiacetate 98.5 % K Hydrogenated starch hydrolyzate Trisodium Ethylenediamine Disuccinate 98.5 % L Hydrogenated starch hydrolyzate Tetrasodium Glutamate Diacetate 98.5 % NOT Hydrogenated starch hydrolyzate nothing 99 % V nothing Disodium cocoamphodiacetate 99.5 %

Each composition in the table above was tested on strands of natural curly hair. Each section of hair was first washed with a commercially available shampoo and detangled. The samples were then air-dried and sprayed with water five times per wick. While the strands were still damp, equal amounts of a test composition were applied to each strand of hair and then styled. After the strands were air dried, they were placed in a humidity chamber at 80% relative humidity at 25 C for one hour.

After one hour in the humidity chamber, the treated strands were qualitatively assessed for curl definition, frizz control and sensory profile. A rating of 1 to 5 was given for frizz control and curl definition, where 1 represented the least amount of frizz control/definition and 5 the most. The sensory profile was determined by manually palpating each strand. A description of the term coated was given when the hair had a coated feel which was a neutral description.

The following Table 4 shows the results of the assessment and the scores of the visual properties of the hair strands treated with the test compositions.

*Scale of 1 to 5, where 1 = least amount of curl definition/frizz control and 5 = maximum amount of curl definition/frizz control

As shown in Table 4, the synergy of sugar and chelating agent provided curl definition, frizz control, and improved feel, as shown in Examples G through L. Sample J was the most effective in using hydrogenated starch hydrolyzate as the sugar and disodium cocoamphodiacetate as the chelating agent to provide optimal frizz control and curl definition while providing a smooth, buttery feel to the hair. Control samples F, N, and V all received the lowest rating for curl definition and frizz control.

The results of this example demonstrate that the synergy of the chelating agent and sugar provides superior frizz control, curl definition and feel to the hair compared to compositions with chelating agents or sugars alone.

Example 3. Optimal concentration of chelating agent with sugar

In order to demonstrate the optimal concentration of chelating agents in combination with sugar according to the disclosure on curly hair, the following water compositions with varying concentration of chelating agents and sugar 1% (O-S) and compositions t ( N,T and U) controls were prepared.

Each composition listed in Table 5 was tested on strands of natural curly hair. Each section of hair was first washed with a commercially available shampoo and detangled. The samples were then air-dried and sprayed with water five times per wick. While the strands were still damp, equal amounts of a test composition were applied to each strand of hair and then styled. After the strands were air dried, they were placed in a humidity chamber at 80% relative humidity at 25 C for one hour.

After one hour in the humidity chamber, the treated strands were qualitatively assessed for curl definition, frizz control and sensory profile. A rating of 1 to 5 was given for frizz control and curl definition, where 1 represented the least amount of frizz control/definition and 5 the most. The sensory profile was determined by manually palpating each strand. A description of the term coated was given when the hair had a coated feel which was a neutral description.

The following Table 6 shows the results of the assessment and the scores of the visual properties of the hair strands treated with the test compositions.

*Scale of 1 to 5, where 1 = least amount of curl definition/frizz control and 5 = maximum amount of curl definition/frizz control

As shown in Table 6, an optimal range of chelating agent was found. All locks with the combination of chelating agent and sugar (O-S) showed better curl definition and frizz control compared to the N,T and U control locks. At 2% loading level and above disodium cocoamphodiacetate, a waxy coating was observed on the hair and a high amount of drag was observed in the Q-S strands. The O and P strands provided the ideal sensation with a loading level of 0.2% and 0.5% chelating agent.

The results of this example demonstrate that the ideal loading level of the chelating agent is between 0.2% and 0.5% when combined with sugar. When combined with an ideal sugar loading level, hair has good frizz control, curl definition and feel.

Example 4. Optimal sugar concentration.

In order to demonstrate the optimal sugar concentration according to the disclosure on curly hair, the following water compositions with varying concentration of sugars and 0.5% chelating agent (W-AA) and a comparative sugar-free composition (V and AB) were prepared.

[Table 7] Chelating agent and sugar compositions Sample Disodium cocoamphodiacetate % Hydrogenated starch hydrolyzate % Water V 0.5% 0% 99.5% W 0.5% 0.5% 99% X 0.5% 1% 98.5% O 0.5% 5% 94.5% Z 0.5% 10% 89.5% AA 0% 1% 99% AB Water only -- 100%

Each of the V-AB compositions was tested on strands of natural curly hair. Each section of hair was first washed with a commercially available shampoo and detangled. The samples were then air-dried and sprayed with water five times per wick. While the strands were still damp, equal amounts of a test composition were applied to each strand of hair and then styled. After the strands were air dried, they were placed in a humidity chamber at 80% relative humidity at 25 C for one hour.

After one hour in the humidity chamber, the treated strands were qualitatively assessed for curl definition, frizz control and sensory profile. A rating of 1 to 5 was given for frizz control and curl definition, where 1 represented the least amount of frizz control/definition and 5 the most. The sensory profile was determined by manually palpating each strand. A description of the term coated was given when the hair had a coated feel which was a neutral description.

The following Table 8 presents the results of the assessment and the scores of the visual properties of the hair strands treated with the test compositions.

*Scale of 1 to 5, where 1 = least amount of curl definition/frizz control and 5 = maximum amount of curl definition/frizz control

As shown in Table 8, an optimal sugar range has been demonstrated. All strands with the combination of chelating agent and sugar (W-Z) showed better curl definition and frizz control compared to control samples V, AA and AB. Strands Y and Z with a higher sugar loading level showed good frizz control and curl definition, and had a straight hair feel. W and

The results of this example show that the ideal sugar loading level is between 0.5% and 1%. Combined with an ideal loading level of chelating agent, hair has good frizz control, curl definition and feel.

Example 5. Formulation tests

In order to demonstrate the invention in a typical hair formulation according to the disclosure on curly hair, the following compositions of comparative and inventive formulations were prepared.

[Table 9] Prepared formulations

INCI name Comparative example 1 Inventive Example 2 Water Qs for 100 Qs for 100 Fatty compounds 15.5 15.5 Polymer 4.36 4.36 Conservative 0.8 0.8 Silicon 0.3 0.3 Solvents 8.09 8.09 Surfactant 2 2 Hydrogenated starch hydrolyzate - 1.43 Disodium cocoamphodiacetate - 1.59

A half-head study was carried out on mannequin heads having curly hair to assess the curl definition effect of compositions including a sugar and a chelating agent according to the disclosure, in comparison to comparative compositions not including sugar and chelating agent.

For each mannequin head, the mannequin head hair was first cleaned with a commercially available shampoo. While the hair was still wet or damp, a sufficient amount of Composition 1 was applied to half the head of each mannequin and distributed evenly over the hair with fingers. Approximately the same amount of Composition 2 was then applied to the other half of the head and distributed evenly in a similar manner. The hair on both sides of the model's head was then styled and left to air dry. Once the hair was completely dry, the mannequin was placed in a humidity chamber at 80% relative humidity (RH) at 25 C and monitored after 1 hour.

Hair treated with test composition 2 had better curl definition, better frizz control, and the hair had a more natural, less coated feel than hair treated with composition 1. Additionally, the composition of Trial 2 had better loop recovery and loops started closer to the root.

Example 6. pH dependence

In order to demonstrate the effect of pH according to the disclosure, the following compositions of varying pH values were prepared as shown in Table 10.

Each composition in Table 10 was tested on strands of natural curly hair. Each section of hair was first washed with a commercially available shampoo and detangled. The samples were then air-dried and sprayed with water five times per wick. While the strands were still damp, equal amounts of a test composition were applied to each strand of hair and then styled. After the strands were air dried, they were placed in a humidity chamber at 80% relative humidity at 25 C for one hour.

After one hour in the humidity chamber, the treated strands were qualitatively assessed for curl definition, frizz control and sensory profile. A rating of 1 to 5 was given for frizz control and curl definition, where 1 represented the least amount of frizz control/definition and 5 the most. The sensory profile was determined by manually palpating each strand. A description of the term coated was given when the hair had a coated feel which was a neutral description.

The following Table 11 shows the assessment results and scores of the visual properties of the hair strands treated with the test compositions.
