Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and particularly relates to a natural anti-aging composition, a color-changing lip balm containing the composition, and a preparation method thereof. Background Art

[0002] The skin is the largest organ of the human body and is one of the organs most vulnerable to aging due to external environmental and internal factors. The physiological structure of the lip skin is more fragile compared to other parts of the face. The thickness of the lip skin is only one-third of that of the facial skin and lacks the protection of sebaceous glands. This characteristic makes the lip skin extremely vulnerable to various external factors, such as ultraviolet radiation and the influence of a dry environment. Under the long-term action of these influencing factors, the dermis and epidermis of the lip skin become thinner, the elasticity weakens, the synthesis of collagen in the dermis decreases and the degradation increases, the collagen structure is disordered. At the same time, hyaluronic acid in another important extracellular matrix of the dermis will decrease, making the skin less plump, sagging, showing more obvious wrinkles, dull color, increased pigmentation, uneven skin color and other problems, seriously affecting the beauty and health of the lips. Therefore, a lip care product that can continuously keep the lip skin moisturized, brighten the lip color, resist aging, and is mild, safe and stable is one of the necessary means for daily lip care.

[0003] A lip balm is a daily necessity that can modify the lips and keep them shiny and moisturized. The main ingredients of general lip balms include wax, oil, pigments, etc. Among them, wax and oil are the main factors for the lip balm to maintain a solid form, facilitate use, and care for the lips. In recent years, different from the limitation of the fixed color of traditional lip balms, color-changing lip balms that can change color according to the user's body temperature, pH value and other physiological conditions have gradually become popular. Although certain progress has been made in color-changing lip balm technology, there are still some challenges, such as how to solve the problem of color spots on color-changing lip balms, how to extend the storage duration, how to solve the problem of too hard lip balm for easy application, how to solve the problem of weak anti-aging effect, and how to solve the stability and persistence of color powder. At the same time, with the improvement of consumers' awareness of health and environmental protection, more and more consumers are beginning to seek natural ingredients and expect natural ingredients to bring anti-aging effects such as moisturizing, nourishing, anti-wrinkle, and brightening the color while keeping the product stable and safe. In summary, how to efficiently prevent the aging of lip skin, solve and achieve long-lasting moisturization, nourishment, anti-wrinkle, and brighten the lip color, while being mild, safe and stable, etc. are important research topics in the field of cosmetics. Therefore, it is necessary to develop a new technical solution to solve the problems existing in the prior art and products. Summary of the Invention

The test results are shown in Table 4. Table 4 Stability and safety test data

[0020] Consumer sensory evaluation Sensory evaluation of the samples of Examples 1-6 and Comparative Examples 1-4. The paste of the present invention is softer than that of general lipsticks. In the softness and hardness score (the higher the score, the softer it is), it is greater than 8.5 and has an ice cream texture when applied. From the data of the consumer evaluation form, it can be seen that the color-changing lipstick added with the natural anti-aging composition involved in the present invention can have a good smell and sensory experience, and can have a good moisturizing feeling both 1 hour and 3 hours after use, can long-term protect the lip skin, and at the same time, the lipstick is mild and non-irritating during use, and there are no adverse phenomena such as color spots, delamination / cracks, silicone imprints / oil imprints. The test results are shown in Table 5. Table 5 Analysis of consumer sensory evaluation data (30 people)

[0021] Friction force test The samples of Examples 1-6 and Comparative Examples 1-4 were subjected to a friction force test. The instrument Brookfield CT3 texture analyzer was used to test the adhesion of the samples. The test data combined with the sensory evaluation of the samples during use showed that the lipstick added with the natural anti-aging composition of the present invention had a better use feeling during use and improved the consumer's use experience. The test results are shown in Table 6. Table 6 Analysis of friction force data

[0022] Moisturizing efficacy evaluation test The samples of Examples 1-6 and Comparative Examples 1-4 were subjected to a moisturizing efficacy evaluation test. 31 Asian adult women aged 24 to 49 were selected as subjects. After continuously using the products of the examples and comparative examples for 28 days under normal conditions, a skin moisture tester Corneometer CM825 was used to measure the water content of the skin cutin of the lower lip, the trans-epidermal water loss TEWL value of the skin, and a skin glossiness test probe Glossymeter GL200 was used to test the skin glossiness, and data was collected to measure the improvement of the samples on the lip moisturization. The results showed that after continuously using the lipstick added with the composition for 28 days, Examples 1-6 could effectively increase the water content of the skin stratum corneum by more than 21% and reduce the skin water loss by more than 19%, indicating that using the composition had a good moisturizing effect. The lipstick added with the composition of the present invention could enhance the barrier function, reduce the skin water loss, and improve the lip skin gloss. Specifically, it is shown in Table 7. Table 7 Analysis of moisturizing data \ Increase in skin stratum corneum moisture Decrease in skin transepidermal water loss Increase in skin glossiness Example 1 22.28％ -20.54％ 18.47％ Example 2 22.58％ -20.05％ 19.48％ Example 3 21.20％ -25.41％ 19.07％ Example 4 21.99％ -19.03％ 18.25％ Example 5 24.26％ -19.08％ 18.78％ Example 6 25.43％ -21.65％ 17.97％ Comparative Example 1 15.42％ -12.19％ 10.55％ Comparative Example 2 17.33％ -13.20％ 16.16％ Comparative Example 3 12.46％ -13.24％ 10.15％ Comparative Example 4 12.45％ -13.86％ 10.25％

[0023] Anti-wrinkle efficacy evaluation test The anti-wrinkle efficacy evaluation tests were carried out on the samples of Examples 1-6 and Comparative Examples 1-4. 31 Asian adult women aged 24 to 49 years were selected as subjects. After continuously using the products of the examples and comparative examples for 28 days under normal conditions, lip images were collected by the skin rapid optical imaging system PRIMOS-CR to analyze skin wrinkles. The results showed that the lip balm added with the natural anti-aging composition of the present invention could effectively reduce the wrinkle depth, wrinkle area, wrinkle number and wrinkle density of the lip skin. Through scientific proportioning, the composition synergistically enhanced the effect and had remarkable effects in anti-wrinkle aspects such as reducing wrinkle depth, reducing wrinkle area, reducing wrinkle number, etc. Specifically, as shown in Table 8.
