Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically referring to a cosmetic composition for skin whitening and anti-aging. Background Technology

[0002] As people's demand for improved skin health and appearance continues to rise, cosmetics with both whitening and anti-aging effects are gaining increasing attention. Dull skin and aging are mainly related to the following factors: 1) Excessive melanin production and deposition; 2) Oxidative damage caused by free radicals; 3) Collagen loss and decreased cell activity; 4) Damaged skin barrier leads to moisture loss.

[0003] While existing technologies have solutions for achieving skincare effects using plant essential oils, such as single or simple compound essential oil systems, they still suffer from limitations such as single or unstable efficacy, insufficient penetration of active ingredients, lack of systematic anti-aging mechanisms, irritation or safety issues, and lack of synergistic design. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a cosmetic composition for skin whitening and anti-aging.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a cosmetic composition for skin whitening and anti-aging, comprising the following components: 1.0-6.0% of plant essential oil compound system, 0.5-5.0% of whitening active compound system, 0.05-3.0% of anti-aging active compound system, 0.5-8.0% of skin barrier repair system, 0.05-2.0% of nano-delivery carrier, and the balance being a basic carrier.

[0006] Furthermore, the plant essential oil compound system includes the following components: 0.1-2.0% rose essential oil, 0.1-2.0% neroli essential oil, 0.05-1.5% frankincense essential oil, and 0.1-2.5% carrot seed essential oil.

[0007] Furthermore, the whitening active compound system includes the following components: niacinamide 1.0-4.0% and tranexamic acid 0.1-2.0%.

[0008] Furthermore, the anti-aging active compound system includes the following components: oligopeptide-10.01-0.5% and coenzyme Q100.05-1.0%.

[0009] Furthermore, the skin barrier repair system comprises the following components: ceramide 0.05–1.0%, cholesterol 0.05–1.0%, and C16–C18 fatty acids 0.1–3.0%.

[0010] Furthermore, the nanodelivery carrier is a liposome, which is composed of phospholipids and cholesterol.

[0011] Furthermore, the C16-C18 fatty acids are selected from stearic acid, palmitic acid, and oleic acid.

[0012] Furthermore, the base carrier is one of squalane, caprylic / capric triglyceride, jojoba oil, grape seed oil, butylene glycol, or water.

[0013] This solution also discloses a method for preparing a skin-whitening and anti-aging cosmetic composition, which mainly includes the following steps: Step 1: Add the whitening active compound system and the skin barrier repair system to deionized water, and stir at room temperature until completely dissolved to obtain the aqueous phase; Step 2: Heat the base carrier and nano-delivery carrier to 70-75℃ to completely melt them, obtaining the oil phase; Step 3: Under stirring conditions, slowly add the oil phase to the aqueous phase and homogenize using a high-speed homogenizer for 5 to 10 minutes at a speed of 8000 to 12000 rpm to form a primary emulsion; Step 4: Cool to below 40℃, then add the whitening active compound system and the anti-aging active compound system in sequence; Step 5: Add the plant essential oil blend at 30-35℃ and stir at low speed for 10 minutes; Step 6: Adjust the pH to 5.5-6.5, filter (200 mesh) to obtain the final product.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Synergistic effect of multiple mechanisms: whitening + anti-oxidation + anti-aging + barrier repair.

[0015] (2) Significantly improves transdermal absorption and nanoliposome delivery.

[0016] (3) High stability, active ingredients are encapsulated and protected.

[0017] (4) Safe and mild, reducing irritation.

[0018] (5) The effect is significantly enhanced, and the synergistic effect of each component is better than that of a single component. Detailed Implementation
