Description

Technical Field

[0001] This invention belongs to the field of shampoo and hair care, and specifically relates to a shampoo and hair care composition containing black spruce extract. Background Technology

[0002] With the development of the times, more and more consumers are paying more attention to the health of their hair and scalp. Problems such as excessive dandruff, excessive scalp oil secretion, severe hair loss, or dry and frizzy hair caused by perming are the most concerning issues. Hair care products that can solve these problems are also highly favored by consumers.

[0003] Scalp care products are mainly divided into two categories: 1) Wash-off scalp care products, which primarily focus on hair washing and conditioning while also providing scalp care. These products utilize mild surfactants, special oils, and natural active ingredients to improve hair condition and provide some scalp care. 2) Leave-on scalp care products, which are applied directly to the scalp and massaged in until absorbed to improve scalp problems. These products primarily achieve their goal of improving scalp health by adding effective ingredients. Currently, most hair care products on the market are chemically synthesized or compounded formulations that can address various hair problems to varying degrees, offering some immediate results. However, they often cause negative effects such as increased oiliness, stickiness, and dandruff. For example, cationic polymers can accumulate excessively on the hair, making it oily and dull; surfactants, with long-term use, may deposit on the scalp, irritating itching and even causing dandruff. During the testing of shampoo and conditioner products, the damaging effects of surfactants on the scalp, excessive or incomplete cleaning, and vigorous scratching can exacerbate scalp conditions, disrupt scalp microbiota, and lead to more hair loss. Furthermore, excessive sebum secretion and peroxidation can further cause scalp problems.

[0004] Therefore, there is an urgent need for a hair care product that can clean the hair and scalp while being gentle on the scalp, and that, in addition to being safe, mild, and non-irritating, can improve scalp condition, soothe the scalp, and smooth the hair. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a shampoo and conditioner composition containing black spruce extract, which is less irritating, can improve scalp condition, regulate the water-oil balance of the scalp, reduce oil secretion, achieve the effect of oil control and dandruff removal, effectively soothe the scalp, increase the combability of dry and wet hair, and make the hair smoother.

[0052] S3. Add black spruce extract, Guangxi mandarin orange peel extract, skin conditioning agent, polyol, fragrance agent, and preservative and stir. Add pH adjuster to adjust the pH value to 5.2-5.5 to obtain a shampoo and conditioner composition containing black spruce extract.

[0053] The specific amounts of each component used in the examples and comparative examples are shown in Table 1 below, in units of weight percentage.

[0054] Table 1:

[0055]

[0056] The Guangxi mandarin orange peel extract used in the examples and comparative examples is a commercially available product.

[0057] The efficacy of the shampoo and conditioner compositions prepared in the above embodiments and comparative examples was evaluated using both instrumental efficacy evaluation and human sensory evaluation methods.

[0058] (1) Seventy volunteers with symptoms of itchy scalp and dandruff were randomly selected and divided into seven groups of 10 people each. They used the shampoo and hair care compositions in the examples and comparative examples, shampooed their hair once a day, and measured the scalp oil content 3 hours and 6 hours after using the shampoo and hair care compositions for seven consecutive days. The dandruff effect before and after using the shampoo and hair care compositions was observed, statistically analyzed and scored. The average test results are shown in Table 2.

[0059] (2) According to the determination method of GB 13173-2008, take 2.5g of each of the shampoo and hair care composition prepared in the examples and comparative examples, dissolve them in 150mg / kg hard water, transfer them to 1000mL volumetric flasks, dilute to the mark, shake well, and then place the solution in a constant temperature water bath at (40±0.5)℃ for aging. The total time from the start of adding water to dissolve the sample is 30min. Then, the foam height is measured with a Roche foam meter and the foam half-life is recorded. The results are shown in Table 2.

[0060] (3) The testing methods for wet hair combing power and dry hair combing power are well-known in the field and will not be described in detail here; the skin redness zone score improvement and soothing feedback score are human sensory evaluations, and the higher the value, the better the effect.

[0061] Table 2:

[0062] Test Project Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Oil content (μg / cm2) after 3 hours -32.4 -44.1 -47.5 -48.3 10.3 -21.7 12.6 Oil content (μg / cm2) after 6 hours -13.2 -17.3 -18.9 -22.1 14.1 -8.4 13.5 7-day dandruff improvement rate -45.60％ -53.70％ -56.10％ -55.30％ -7.07％ -32.12％ -6.54％ Bubble height (mm) 131 144 154 155 111 117 107 Wet hair combing force conversion rate -35％ -39％ -45％ -46％ -24％ -32％ -23％ Dry hair combing force conversion rate -39％ -43％ -48％ -50％ -21％ -28％ -21％ Foam half-life (s) 191.18 231.06 274.33 294.79 147.64 164.48 135.02 Improved skin redness score 12.44 14.14 15.61 16.57 4.14 6.24 -3.62 Soothing feedback rating 89 92 94 95 65 71 33

[0063] Table 2 shows that after 3 and 6 hours of using the shampoo and conditioner composition of the present invention, the scalp oil content is significantly reduced, demonstrating a significant oil-control effect. After one week of use, it effectively improves scalp and dandruff conditions, effectively soothes the scalp, and enhances the skin redness score. The black spruce extract and Guangxi mandarin orange peel extract, when applied to the shampoo and conditioner composition, have a synergistic effect, enhancing the oil-control, dandruff-removing, and soothing effects, improving shampoo foam, increasing foam stability, and improving hair's combability, making hair smoother. Examples 1-4 show that 0.3%-0.7% of black spruce extract is the preferred concentration; further increasing the concentration results in limited improvement in the oil-control effect and other properties of the shampoo and conditioner composition.

[0064] The shampoo and conditioner compositions prepared in the examples and comparative examples were subjected to a chicken embryo irritation test. The chicken embryo irritation test method used was a well-known test method in the art and will not be described in detail here. A score of 0 indicates no irritation, and a score of 5 indicates severe capillary bleeding; the higher the score, the greater the irritation. The chicken embryo irritation test evaluation table is shown in Table 3.

[0066]

[0067] As shown in Table 4, the shampoo and hair care composition provided by the present invention has low irritation and the composition system is mild and safe, making the shampoo more suitable for sensitive scalps.

[0068] This invention, through the rational construction of a shampoo and hair care composition system, applies black spruce leaf extract as the main active ingredient in shampoo and hair care products, combined with Guangxi mandarin orange peel extract. These ingredients complement each other, working together to synergistically enhance the cleansing and repairing effects of the shampoo and hair care composition. This results in superior oil control, dandruff removal, and soothing effects. The resulting shampoo and hair care composition is safe, gentle, and low in irritation, protecting scalp health. It produces rich and stable foam, offering better cleansing and conditioning effects. After use, the combability of both dry and wet hair is significantly improved, leaving hair smooth and supple.
