Description

Technical Field

[0001] This invention relates to the field of personal care products, specifically to a personal care composition and its application, and a method for preparing a shampoo. Background Technology

[0002] With economic development, people have increasingly higher requirements for hair care. Many consumers pursue hair dyeing, perming, and styling. Frequent dyeing and perming can severely damage hair, making it brittle and dull. In addition, with the increasing work pressure and environmental pollution in modern society, people are experiencing more and more skin problems, with scalp problems being the most common, mainly manifested as allergies, itching, hair loss, imbalanced oil secretion, and dandruff.

[0003] Currently, most hair care products on the market rely on dimethicone, amino silicone oil, and cationic conditioners to form a thin film on the hair surface, achieving shine and smoothness. However, with repeated use, excessive cationic and silicone oil deposits on the hair, making it increasingly oily. To address dandruff, the market often uses chemical drugs such as selenium sulfide, piroctone olamine, clomiphene, salicylic acid, zinc pyrithione, and ketoconazole. These chemical drugs typically work by killing Malassezia fungus to improve dandruff, but they have strong side effects. Long-term use can easily lead to scalp dependence, damage hair quality, and even folliculitis.

[0004] Therefore, there is an urgent need to develop hair care products with good oil control, anti-itch, soothing, and stabilizing effects to meet the needs of the growing number of people with skin problems. In particular, there is a need to develop a shampoo that has multiple functions such as oil control, dandruff removal, itch relief, increased hair volume and shine, and effective hair strengthening.

[0094] Everything else is the same as in Example 1.

[0095] Shampoo DS3 was prepared.

[0096] Test case

[0097] Pretreatment: Select genuine black hair (healthy hair strands) from the outside. Wet the hair strands at a water temperature of 37.0℃. Take 1ml of 10wt% sodium lauryl ether sulfate (SLES) and apply it evenly to the hair strands. Gently rub until rich foam is formed for 1 minute to remove oil and dirt from the hair surface. Rinse for 2 minutes at a constant water flow rate. Comb both sides 10 times with a flat narrow-tooth comb. Hang the hair strands in a constant temperature and humidity room to balance and air dry naturally to obtain the hair strands before use.

[0098] Hair strengthening efficacy test:

[0099] 1. Select one identical pretreated cylindrical hair bundle (3g, black healthy hair bundle) and divide it into 2 groups: one bundle for the sample group and one bundle for the control group.

[0100] 2. Sample hair strand treatment method: Apply the shampoo prepared in the above examples and comparative examples evenly to the sample hair strands at a dosage of 0.2 g / g of hair, rub for 1 minute, rinse with water at 37°C and a flow rate of 4 L / min for 1 minute, and stroke the hair strands every 20 seconds. After styling the hair strands, comb them 10 times with a narrow-tooth comb.

[0101] The control group hair strand treatment method: use the same mass of clean water instead of the shampoo used in the sample group hair strand treatment method.

[0102] 3. Hang the hair bundles in a constant temperature and humidity chamber at 21±1℃ and 50±10%RH to balance and air dry naturally; use a combing instrument (model: fibra.one) to measure the tensile work parameters of 60 individual hair bundles, and the results are shown in Table 3;

[0103] The stretching of the sample group was significantly improved compared with that of the control group, indicating that the product has the effect of strengthening hair strands. The higher the rate of change, the better the product effect.

[0104] Formula for calculating hair strength test results:

[0105] Change rate = ((tensile work value of sample group - tensile work value of control group) / tensile work value of control group) × 100%;

[0106] Table 3

[0107] Control group (mJ) Sample group (mJ) rate of change Example 1 11.65 16.25 39.48％ Example 2 12.69 16.75 31.99％ Example 3 10.63 14.14 33.02％ Example 4 10.28 13.05 26.95％ Example 5 13.29 16.47 23.93％ Example 6 9.76 12.30 26.02％ Example 7 15.66 19.35 23.56％ Example 8 14.51 17.77 22.47％ Comparative Example 1 11.28 13.32 18.08％ Comparative Example 2 14.02 16.82 19.97％ Comparative Example 3 12.89 15.46 19.94％

[0108] As can be seen from the test results in Table 3, the shampoo provided by this invention has a better effect on strengthening hair.

[0109] Hair shine and volume test:

[0110] 1. Calculate initial values: The gloss parameter values ​​of the pre-treated hair strands before use were measured using a Skin-Glossymeter GL200 (CK GmbH, Germany), and the results are shown in Table 4; the area of ​​the pre-treated hair strands before use was measured using a facial imaging analyzer (VISIA-6), and the results are shown in Table 5.

[0111] 2. Apply the shampoo prepared in the above examples and comparative examples evenly to the pretreated hair strands at a dosage of 0.2 g / g of hair, rub for 1 minute, rinse with water at 37°C and a flow rate of 4 L / min for 1 minute, and stroke the hair strands every 20 seconds. After stroking the hair strands, comb them 10 times with a narrow-tooth comb, and then hang the hair strands in a constant temperature and humidity chamber at 21±1°C and 50±10%RH to equilibrate and air dry naturally to obtain the hair strands after use. The gloss parameter values ​​of the hair strands after use were measured using a Skin-Glossymeter GL200, and the results are shown in Table 4. The area of ​​the hair strands after use was measured using a facial imaging analyzer (VISIA-6), and the results are shown in Table 5.

[0112] Formula for calculating gloss test results:

[0113] Change rate = ((gloss value after use - gloss value before use) / gloss value before use) × 100%; the higher the change rate, the better the hair shine effect; the results are shown in Table 4;

[0114] Formula for calculating hair volume test results:

[0115] Change rate = ((area of ​​hair strand after use - area of ​​hair strand before use) / area of ​​hair strand before use) × 100%; the results are shown in Table 5; under the premise of better gloss and hair strength, the change rate of the fluffiness test is higher than 100%, indicating that the hair fluffiness effect is good;

[0121] As can be seen from the test results in Tables 3, 4 and 5, the shampoo provided by this invention has a better effect on making hair more voluminous after application.

[0122] Oil control effect test:

[0123] 1. On day D0, after sitting quietly in a constant temperature and humidity room for 30 minutes, a scalp area was selected and the baseline value of scalp oil was tested using a Sebumeter instrument (Sebumeter SM815, CK GmbH, Germany). After receiving the sample, the subject used the sample once every two days. Scalp oil data was collected again on day D28.

[0124] 2. On day D28, the subjects sat quietly in a constant temperature and humidity room for 30 minutes before the test began. On the same area selected on day D0, the Sebumeter instrument was used to test the scalp oil data.

[0125] The oil data from day D28 were compared with the oil data from day D0 to calculate the rate of change.

[0129] The results of the oil control test show that the shampoo provided by the present invention has a better oil control effect when applied to the scalp.

[0130] Anti-dandruff effect test:

[0131] 1. On day D0, after sitting quietly in a temperature and humidity controlled room for 30 minutes, a scalp area was selected, and dandruff was pasted onto the scalp using a Corneofix instrument (Corneofix F20, CK GmbH, Germany). Then, the scalp pasted on the Corneofix instrument was photographed using a VC20 (VisioScan VC20plus, CK GmbH, Germany), and the numerical parameters of its skin surface condition (scalp keratinocyte exfoliation index) were analyzed. After receiving the sample, the subject used the sample once every two days, and the dandruff test was performed again on day D28.

[0132] 2. On day D28, the subjects sat quietly in a constant temperature and humidity room for 30 minutes before the test began. On the same area selected on day D0, dandruff was pasted onto the scalp using a Corneofix device. The dandruff pasted onto the Corneofix device was then photographed using a VC20 (local imaging device), and the numerical parameters of the skin surface condition (scalp keratinocyte exfoliation index) were analyzed.

[0133] The scalp keratinocyte exfoliation index on day D28 was compared with that on day D0, and the rate of change was calculated.

[0134] Change rate = (scalp keratinocyte exfoliation index data on day D0 - scalp keratinocyte exfoliation index data on day D28) / scalp keratinocyte exfoliation index data on day D0 × 100%; the higher the change rate, the better the dandruff removal effect; the results are shown in Table 7;

[0137] The present invention provides, exemplarily, an image illustrating the effect of dandruff improvement in Embodiment 1, as shown below. Figure 1 and Figure 2 As shown, Figure 2 The scalp condition on day D0 before using the shampoo provided by this invention. Figure 1 The image shows the scalp condition on day 28 after using the shampoo provided by this invention. It is clear from the image that the dandruff was significantly improved after using the shampoo provided by this invention.

[0138] The results of the dandruff test showed that the shampoo provided by the present invention has a better dandruff removal effect when applied to the scalp.

[0139] Soothing efficacy test:

[0140] The soothing efficacy was tested using a self-assessment method by the participants.

[0141] Judgment criteria: Self-reported scores of all subjects on day 28; higher scores indicate better relief.

[0142] Evaluation indicators (feelings after using the sample): 1 point indicates strong disagreement, 2 points indicates some disagreement, 3 points indicates neither disagreement nor agreement, 4 points indicates some agreement, and 5 points indicates strong agreement.

[0143] Judgment criteria: Self-assessment score = (sum of the number of people who scored 4 and 5) / total number of people tested × 100%; the higher the self-assessment score, the better the relief effect; test results are shown in Table 8.
