Light-sensitive brightening essence cream and preparation method thereof

Abstract

According to the light-sensitive brightening essence cream and the preparation method thereof, a multi-channel whitening technology (melanin generation inhibiting, transport blocking and metabolism accelerating) is used for cooperating with moisturizing barrier repairing, and the multiple effects that the skin is transparent, bright, moisturized and fine are achieved. The preparation method comprises the steps of raw material pretreatment, oil phase / water phase preparation, emulsification and homogenization, sterile filling and the like, and is suitable for improving the skin problems of darkness, roughness and loose fine wrinkles.

Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a light-reflecting and brightening essence cream with multi-pathway whitening as its core and its preparation method, which is suitable for people with rough, dull, and sagging skin and fine lines. Background Technology

[0002] Currently, whitening skincare products have the following problems: 1. Limited efficacy: Most products contain only niacinamide or vitamin C derivatives, which can only inhibit melanin transport and cannot block its formation at the root; 2. High irritation: High concentrations of whitening ingredients (such as kojic acid) can easily trigger allergies or peeling. 3. Insufficient moisturizing: The whitening and moisturizing functions are disconnected, and dry environments can easily worsen dull skin. 4. Limited penetration: Large molecules (such as sodium hyaluronate) have difficulty penetrating the stratum corneum and have low absorption rates.

[0003] To address the aforementioned issues, this invention provides a multi-effect, synergistic, gentle, and highly effective radiance-enhancing essence cream. Summary of the Invention

[0004] Composition The light-reflecting and brightening essence cream of this invention is composed of the following ingredients in parts by weight: Core whitening ingredients: Nicotinamide (99% purity) 8-15 parts Tranexamic acid (5-10 parts) Licorice root extract (glycyrrhizin ≥2%) 4-8 parts Tea extract (tea polyphenols ≥40%) 3-6 parts Moisturizing barrier repair ingredients: Sodium hyaluronate (molecular weight 100-300kDa) 3-6 parts 10-18 parts avocado resin 8-15 parts jojoba seed oil Inositol (Vitamin B7) 2-5 parts Plant antioxidant components: Centella asiatica extract (asiaticoside ≥20%) 6-12 parts Rosemary extract (rosmarinic acid ≥3%) 5-10 parts Chamomile extract (bisabolol ≥1%) 4-8 parts Sophora japonica flower extract (rutin ≥ 5%) 3-6 parts Ophiopogon japonicus extract (Ophiopogon japonicus polysaccharide ≥10%) 2-5 parts Chlorella extract (phycocyanin ≥1%) 1-3 portions Rose extract (anthocyanins ≥ 0.5%) 1-3 servings auxiliary ingredients: Tocopherol (Vitamin E) 1-3 parts, Arginine (pH adjuster) 0.5-2 parts Production method 1. Raw material pretreatment: Place the avocado resin and jojoba seed oil at -20°C for 24 hours, then filter to remove impurities after thawing. Plant extracts (such as Centella asiatica and rosemary) are extracted using supercritical CO2 and concentrated to a solids content of ≥20%. Sodium hyaluronate is dissolved in 0.1% citric acid solution after centrifugation and filtration, and the pH is adjusted to 6.0-6.5.

[0005] 2. Oil phase preparation: Mix avocado resin, jojoba seed oil, and tocopherol, heat to 70°C, and stir at 300 r / min until uniform and transparent to form an oil phase matrix.

[0006] 3. Aqueous phase preparation: Dissolve nicotinamide, tranexamic acid, licorice root extract, and tea extract in deionized water, add arginine to adjust the pH to 5.8-6.2, and heat to 65℃. Add sodium hyaluronate, inositol, and plant extracts (centella asiatica, rosemary, etc.) in sequence, and stir at 200 r / min until completely dissolved to form an aqueous matrix.

[0007] 4. Emulsification and homogenization: The oil phase was slowly added to the aqueous phase, and the mixture was sheared at 1800 r / min for 20 minutes to form a primary emulsion. Add Sophora japonica extract, Ophiopogon japonicus extract, Chlorella extract, and rose extract, and continue cutting for 10 minutes; The mixture was processed twice by a high-pressure homogenizer (15 MPa) to form a nanoemulsion with a particle size of <500 nm.

[0008] 5. Final blending and filling: Performance testing: tests viscosity (20-40 Pa·s at 25℃), pH value (5.5-6.5), and microbial indicators (total bacterial count <10 CFU / g). Filling: Use an aseptic vacuum filling machine to fill into brown glass bottles (50g / bottle), seal with nitrogen, and store away from light.
