The subsequent addition of starch octenylsuccinate can improve the stability of the composite plant extract inclusion compound.

Description

Technical Field

[0001] The invention relates to the technical field of shampoo, and in particular to a shampoo composition containing a safflower extract and a preparation process thereof. Background Art

[0002] As living standards improve, consumers are increasingly demanding natural and safer personal care products. The development of plant-based active ingredients with both antibacterial and antioxidant properties has become a key research focus in the daily chemical industry. Traditional shampoos rely on synthetic ingredients such as ketoconazole, zinc pyrithione, silicone oil derivatives, and salicylic acid to achieve dandruff removal and smoothing effects. However, long-term use of these products can lead to scalp irritation, microbial imbalances, and chemical residues, making them unable to meet consumer demand for healthy shampoos.

[0003] As a traditional medicinal plant in my country, the leaves of the herb are rich in various active ingredients, including flavonoid glycosides and gallic acid derivatives. Studies have found that extracts from the herb have significant inhibitory effects on common scalp pathogens such as Staphylococcus aureus and Malassezia, and also have the potential to scavenge free radicals and mitigate oxidative damage. However, prior research on the active ingredients of the herb has primarily focused on the pharmaceutical field, with their application in daily chemical products, particularly shampoos, remaining largely unexplored. Furthermore, the use of plant extracts in complex shampoo formulations can be susceptible to oxidation or interaction with surfactants, resulting in decreased stability and efficacy.

[0004] Therefore, a shampoo composition containing a Cynanchum wilfordii extract with high stability and a preparation process thereof are proposed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a shampoo composition containing a Psoralea corylifolia extract and a preparation process thereof.

[0023] S2.3: Add 2-3 parts by weight of the composite plant extract powder to 5-8 parts by weight of a 70-80% ethanol solution, then add 10-12 parts by weight of the glucan solution, adjust the pH to 5, and stir at 500-600 rpm for 60-70 minutes to obtain a mixed solution;

[0024] S2.4: The mixed solution was subjected to rotary evaporation and then supplemented with ultrapure water to the original volume to obtain a dispersion, which was added to the zein suspension at a volume ratio of 1:1-2. Octenyl succinate starch was then added, followed by stirring at 500-600 rpm for 60-70 min, adjusting the pH to 5, filtering through a 0.45 μm filter membrane, and then freeze-drying to obtain a composite plant extract inclusion complex.

[0033] Compared with the prior art, the present invention has at least the following beneficial effects:

[0034] 1. The present invention forms an amphiphilic composite structure by combining zein and glucan, which can effectively embed the composite plant extract. The composite structure protects the plant extract from degradation by light, heat, oxidation or enzymatic hydrolysis through physical barriers and chemical interactions, thereby extending the shelf life, improving the stability of the composite plant extract in the shampoo composition, and avoiding weakening of the efficacy. The added octenyl succinate starch ester serves as an amphiphilic polymer and can be adsorbed at the interface between zein and glucan, reducing surface tension and forming a more stable core-shell structure. The long-chain structure of the octenyl succinate starch ester can form a hydration layer on the particle surface, which together with the glucan provides a steric hindrance effect, resisting damage to the inclusion compound by the external environment, improving the stability of the composite plant extract inclusion compound, and extending the storage time of the composite plant extract inclusion compound in the shampoo composition.

[0035] 2. The present invention quickly locks in freshness through liquid nitrogen quick freezing, inhibits the activity of polyphenol oxidase, reduces the oxidative loss of polyphenols in Aronia nigra and Aronia serrata leaves, and retains high antioxidant activity. The Aronia nigra fruit extract is compounded with the Aronia serrata leaf extract. The polyphenols in the Aronia nigra fruit extract have extremely strong antioxidant ability and can effectively scavenge free radicals. It also has a significant inhibitory effect on common pathogens and fungi such as Staphylococcus aureus and Aspergillus fumigatus, and can achieve the purpose of anti-inflammatory and anti-dandruff. The Aronia serrata leaf extract has the effect of clearing away heat and detoxifying, and has a significant therapeutic effect on bacterial infections. The extract achieves antibacterial effect by destroying cell walls and inhibiting microbial activity. The combination of the two can cover a wider spectrum of pathogens, reduce dandruff and inflammatory reactions, and protect the scalp from oxidative damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] Comparative Example 1

[0082] Compared with Example 1, Comparative Example 1 is different in that, in Comparative Example 1, the Aronia melanocarpa fruit in step S1.1 is removed, and the other steps remain unchanged to prepare the shampoo composition, which is recorded as Comparative Example 1.

[0083] Comparative Example 2

[0084] Compared with Example 1, Comparative Example 2 is different in that the leaves of Scutellaria baicalensis in step S1.1 are removed from Comparative Example 2, and the shampoo composition is prepared with the remaining steps unchanged, which is recorded as Comparative Example 2.

[0085] Comparative Example 3

[0086] Compared with Example 1, Comparative Example 3 is different in that the octenyl succinate starch ester in step S2.4 is removed from Comparative Example 3, and the remaining steps are unchanged to prepare the shampoo composition, which is recorded as Comparative Example 3.

[0087] The shampoo compositions prepared in Examples 1-3 and Comparative Examples 1-2 were tested for hyaluronidase inhibition rate, antibacterial rate, and DPPH clearance rate. The test results are shown in Table 1.

[0088] The antibacterial rate was determined using a mixed strain prepared by mixing Staphylococcus aureus, Escherichia coli, Candida albicans, Malassezia furfur and Aspergillus fumigatus in a mass ratio of 1:1:1:1:1.

[0089] Table 1. Performance test results of Examples 1-3 and Comparative Examples 1-2

[0090]

[0091] As can be seen from the data in Table 1, the combination of the Aronia nigra fruit extract and the Scutellaria serrata leaf extract of the present invention can significantly improve the antibacterial ability and increase the hyaluronidase inhibition rate, indicating that it can reduce inflammatory reactions and protect the scalp from oxidative damage.

[0092] The shampoo compositions prepared in Examples 1-3 and Comparative Example 3 were allowed to stand for 6 months and then the hyaluronidase inhibition rate, antibacterial rate and DPPH clearance rate were measured again. The measurement results are shown in Table 2.

[0093] Table 2. Performance test results of Examples 1-3 and Comparative Example 3

[0094]

[0095] As can be seen from the data in Table 2, after the addition of starch octenyl succinate, the efficacy of the shampoo compositions of Examples 1-3 did not significantly decrease after being placed for 6 months, while the hyaluronidase inhibition rate, antibacterial rate, and DPPH clearance rate of Comparative Example 3 all decreased significantly compared with Examples 1-3 after being placed for 6 months. This is because the added starch octenyl succinate can enhance the stability of the plant extract inclusion compound and prolong the shelf life of the composite plant extract inclusion compound in the shampoo composition, thereby maintaining the efficacy of the shampoo composition.

[0096] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
