Introduction
Rice Phytoceramide, a natural lipid from Oryza sativa L. rice bran, is a high-value active ingredient widely used in cosmetics, functional foods and pharmaceuticals. As a plant-derived alternative to synthetic and animal-sourced ceramides, it features superior safety, biocompatibility and efficacy for high-end formulations.
Raw Material Source: Extracted from high-quality non-GMO rice bran, sourced from pollution-free bases with strict quality control to avoid heavy metals and pesticides. Optional sea red rice bran (salt-tolerant) is available for enhanced bioactivity due to higher minerals and lipids.
Extraction Process: Adopting GMP-compliant, eco-friendly co-fermentation (yeast & lactic acid bacteria) + ultrasonic-assisted ethanol extraction. Key steps: pretreatment, co-fermentation (30-37℃, 5-7 days), ultrasonic extraction, purification and quality inspection. It avoids harmful solvents, retains bioactivity, with an extraction yield up to 12.54%.
Active Ingredient Content: Customizable glucosylceramide (main active form) content: 1%-10% (standard), up to 98% (high-purity). HPLC-tested for accuracy (CV ≤ 5%), with trace synergistic ingredients like β-sitosterol glucoside.
Differentiation Advantages: Compared with synthetic/other plant ceramides,
- High biocompatibility (similar to human skin ceramides, no irritation);
- 100% plant-derived, non-GMO, certified by ISO/FDA/Halal/Kosher;
- Multi-efficacy (moisturizing, skin wellness support, anti-allergic);
- Stable performance (soluble in ethanol/water, pH 4.0-8.0, ≤80℃);
- Cost-effectiveness from advanced process and abundant raw materials.
Key Active Compounds
Core active components are natural glucosylceramides (GlcCer) and derivatives, composed of sphingoid bases and fatty acids. Key compounds:
-
Glucosylceramides (GlcCer): 70-85% of total content, main subtypes include Cer 18:0/24:0 (2OH) and Cer 18:0/26:0. Responsible for moisturizing, barrier repair and skin wellness support, convertible to free ceramides in the human body.
-
Phytosphingosine (PS): 5-10% of total, with antibacterial/anti-inflammatory effects, regulating skin cell function and enhancing barrier.
-
Sphingosine (S) & Dihydrosphingosine (DS): 3-5% total, synergizing with GlcCer to improve hydration and elasticity.
-
Synergistic Ingredients: β-sitosterol glucoside, linoleic acid, etc., enhancing solubility, absorption and auxiliary efficacy.
Benefits
Rice Phytoceramide offers proven multi-dimensional skin benefits, supported by in vitro/in vivo/clinical studies, applicable to multiple fields:
Skin Health Benefits (Topical & Oral)
-
Intensive Moisturizing & Barrier Repair: Reduces TEWL by 30-50%, improves hydration by 40-60%, repairs barriers damaged by aging/environment, relieving dryness.
-
Anti-Acne & Soothing: Regulates skin immunity, supports normal inflammatory response, suitable for sensitive skin, cutting cosmetic-related allergy risk by over 70%.
-
Depigmentation & Brightening: Reduces melanin/erythema index, improves dullness via inhibiting melanin synthesis and promoting cell renewal.
Other Potential Benefits
-
Oral Health Support: Improves oral mucosa moisture, relieves dry mouth and reduces oral ulcers.
-
Immune Regulation: Preliminary studies suggest regulatory effects, requiring further clinical confirmation.
