Description

Technical Field

[0001] This invention relates to compositions for increasing hair volume, said compositions comprising a quaternized copolymer of salicylic acid and vinylpyrrolidone with dimethylaminoethyl methacrylate. The compositions according to the invention can increase hair volume. Background Technology

[0002] Consumers with fine hair often lack normal volume due to the small diameter of individual hair strands, and fine hair often collapses under its own weight, resulting in a flat and lifeless hairstyle. Furthermore, consumers with oily scalps often have flat hair, which affects the overall visual effect. Therefore, in addition to consumers with thinning hair, those with fine hair and those with oily scalps also desire to increase hair volume. Moreover, a high crown and voluminous hair can create the illusion that the outer contour is larger than the inner contour (also known as a "head-wrapping-face"), making the consumer's face appear smaller and more delicate in photos. Therefore, more and more consumers are pursuing voluminous hair, especially voluminous hair at the crown, and are therefore seeking products that add support and texture to dry hair to make it appear larger.

[0003] However, traditional products used to increase hair volume are usually styling products or simply deep-cleansing products. Both of these only temporarily increase hair volume. Furthermore, none of the hair volume products on the market can meet consumers' demands for effective hair volume enhancement.

[0004] Therefore, it is desirable to provide a composition for increasing hair volume that improves the effect of increasing hair volume. Summary of the Invention

[0005] The present invention provides a composition for increasing hair volume, the composition comprising salicylic acid and a quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate.

[0006] The present invention also provides a shampoo comprising a composition according to the invention for increasing hair volume.

[0007] The present invention further provides the use of the composition for increasing hair volume according to the present invention for increasing hair volume.

[0008] The compositions, shampoos, and uses for increasing hair volume according to the present invention are all based on the inventors’ surprising discovery that the compositions for increasing hair volume according to the present invention, utilizing a specific combination of salicylic acid and vinylpyrrolidone with a quaternized copolymer of dimethylaminoethyl methacrylate, can increase hair volume.

[0066] I. The effect of quaternized copolymers of vinylpyrrolidone and dimethylaminoethyl methacrylate on hair volume-increasing properties Table 1

[0067] Note: All "-" symbols in this article indicate that the corresponding component is not present.

[0068] To evaluate the effect of the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate on the hair volume-increasing properties, for each composition from Ex.1 to Ex.3, healthy Chinese hair strands were pre-cleaned by washing once with a 5% SLES (sodium lauryl ether sulfate) solution and hanging overnight to dry in a constant temperature and humidity environment (Rh 55%, 22°C). The dried hair strands were then pre-treated with sebum by immersing them in 20 g of a 1% artificial sebum solution for 1 minute, removing them, squeezing out excess solution, and drying at 40°C. Following this, the hair strands were washed with each composition from Ex.1 to Ex.3 at a rate of 0.6 ml per strand, rubbing for 30 seconds and rinsing for 30 seconds. The cleaned hair strands were then hung overnight to dry in a constant temperature and humidity environment (Rh 55%, 22°C). Finally, the hair bundles were photographed in the laboratory using a homemade shooting lightbox (4 photos per bundle), and the photos were input into Image Pro image analysis software to calculate the volume of each hair strand.

[0069] The higher the value, the greater the increase in hair volume. The test results for compositions Ex.1 to Ex.3 are... Figure 1 As shown in the image.

[0070] From Table 1 and Figure 1The data shows that, compared with polyurethane-10 and polyquaternium-55, the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate has the best volume in healthy hair in China.

[0071] II. The effect of the combination of salicylic acid and vinylpyrrolidone with a quaternized copolymer of dimethylaminoethyl methacrylate on the hair volume-increasing performance. Table 2

[0072] To evaluate the effect of the combination of salicylic acid and the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate on the hair volume-increasing properties, for each composition from Ex.4 to Ex.6, 2D image areas of hair strands before and after treatment with the composition under test were measured using a beam measurement method to evaluate the volumizing properties of the compositions using the Bolero Hair System.

[0073] Measurement indicators: Main surface area (cm) 2 (This excludes the area of ​​the hair strands that stick up, removing the voluminous effect of the sticking-up hair.) FAF surface (cm) 2 ): Image area of ​​hair strands with curled fibers Total surface area (cm) 2 = Main surface area (cm) 2 ) + FAF surface (cm) 2 ): Including the overall voluminous effect of bouncy hair As used in this article, the main body and the FAF section are as follows: Figure 2 The example shown illustrates this.

[0074] Specifically, for each composition from Ex.4 to Ex.6, three hair bundles were used, each consisting of 3g of 20cm long Chinese natural hair. The hair bundles were pretreated by uniformly applying 0.05g of artificial sebum to each bundle. Then, according to the sensory testing shampoo application SOP, each test composition was applied to the hair bundle twice at a rate of 0.375g each time. Next, the hair bundles were dried at 50% RH and 25°C for 18 hours. Finally, the image area of ​​the dried hair bundles before and after application of the composition was determined using a BoleroTrio testing module.

[0075] The hair image area results for compositions Ex.4 to Ex.6 are shown in... Figure 3 From Table 2 and Figure 3The data shows that, compared to the composition of Ex.4 (which does not contain salicylic acid and the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate) and the composition of Ex.5 (which contains the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate but does not contain salicylic acid), the composition of Ex.6, which utilizes the combination of salicylic acid and the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate according to the present invention, exhibits the best main volume effect and overall volume effect; in other words, the combination of salicylic acid and vinylpyrrolidone and the quaternized copolymer of dimethylaminoethyl methacrylate can significantly increase hair volume.

[0076] Furthermore, for the compositions of Ex.4 to Ex.6, their hair bundle area analysis photographs are shown in... Figure 4 As can be seen from the photographs, compared to the composition of Ex.4 (which does not contain salicylic acid and the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate) and the composition of Ex.5 (which contains the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate but does not contain salicylic acid), the composition of Ex.6, which utilizes the combination of salicylic acid and the quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate according to the present invention, shows a significantly better effect in increasing hair volume.

[0077] III. Salon test of the compositions of Ex.4 and Ex.6 To further examine the shampoo performance of the Ex.4 and Ex.6 compositions in terms of hair volume and lightness, a salon test was conducted. This test was a blind half-head salon test involving three models, and the final results were judged based on a statistical average method.

[0078] Salon testing results showed that, compared to the composition of Ex.4, the composition of Ex.6 exhibited both better hair volume benefits and a better sense of lightness; that is, the combination of salicylic acid and vinylpyrrolidone with the quaternized copolymer of dimethylaminoethyl methacrylate was able to increase hair volume in the shampoo.

[0079] IV. Clinical Testing Table 3

[0080] To further examine the performance of the shampoo containing the combination of salicylic acid and a quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate, and oil-controlling active ingredients, a clinical trial (a human efficacy test) was conducted. A total of 33 individuals (including 33 Chinese female consumers aged 18 to 60 years) completed this human efficacy test, obtaining 33 valid data points, and no adverse events were reported. In this test, the Ex.7 composition was used once every 3 days for the first 2 weeks, and Schwarzkopf Oil Control Shampoo and Conditioner was used once every 3 days for the following 2 weeks. Test measurements included scalp and hair oil content, and crown height.

[0081] Oil levels were measured in the following areas: the central area of ​​the crown, the scalp, and the hair 2cm from the root. The central area of ​​the occipital scalp, and the adjacent hair 2cm from the root.

[0082] Image analysis was performed as follows. Frontal images were captured using a digital camera (analysis metric: crown height). Test time points: elution screening, immediately and 4 hours after the last use of the elution product, baseline value (meaning 72 hours after the last use of the elution product), immediately and 4 hours after the first use of the test product, 4 weeks after use (meaning before the last follow-up date), and 4 hours after the last use of the test product.

[0083] The test results obtained above are summarized as follows: Figures 5 to 8 middle.

[0084] The scalp and hair oil content results for the composition in Ex.7 are as follows: like Figure 6 As shown in the figure, compared with before use, the scalp oil on the back of the head decreased significantly (P<0.05) immediately after the first use, with a decrease rate of 99.06% in total scalp sebum, a decrease rate of 98.94% in scalp sebum on the top of the head, and a decrease rate of 99.03% in hair sebum on the top of the head.

[0085] like Figure 8 As shown, compared with before use, the scalp oil on the back of the head decreased significantly (P<0.05) after 4 weeks of use, with a decrease of 8.35% in total scalp sebum, a decrease of 7.64% in scalp sebum on the crown, and a decrease of 9.29% in hair sebum on the crown.

[0086] The results for hair crown height of the composition in Ex.7 are as follows: like Figure 5As shown, compared with before use, the height of the skull increased significantly (P<0.05) immediately after the first use, and the increase rate was 26.97%.

[0087] like Figure 7 As shown, head height increased significantly (P < 0.05) after 4 weeks compared with before use, with an increase rate of 18.62%.

[0088] As can be seen from the above, the composition of Ex.7 can significantly improve hair volume and reduce scalp and hair oil content both immediately and in the long term.

[0089] In conclusion, the combination of salicylic acid and vinylpyrrolidone with dimethylaminoethyl methacrylate quaternized copolymer can be used in conjunction with other oil-controlling active ingredients and can significantly increase hair volume.

[0090] Although some preferred embodiments have been described, many modifications and variations can be made to them in light of the above teachings. Therefore, it should be understood that the invention can be practiced in ways different from those specifically described without departing from the scope of the appended claims.
