1. Product Introduction

Our Oak Extract is a high-quality plant extract derived from premium natural oak wood raw materials. Rich in oak flavonoids, anthocyanins, polyphenols, organic acids and other beneficial active ingredients, it delivers excellent firming repair, antioxidant brightening, physical conditioning and natural dietary health preservation values. Widely applied in cosmetics, food and beverage, dietary health and other industries, it has gained wide recognition in the market.

2. Active Ingredients

Oak Flavonoids and Anthocyanins

The main active ingredients of oak extract are natural oak flavonoids and anthocyanin compounds. These active substances are renowned for powerful antioxidant, brightening repair, anti-inflammatory and soothing properties, which constitute the core efficacy of oak extract.

Anthocyanins and oak flavonoids are key natural active ingredients intensively studied in the industry. Studies have shown that these components can effectively neutralize free radicals in the human body and on the skin surface. Free radicals are the main cause of skin oxidative dullness, fine lines, body aging and sub-health conditions, enabling the extract to significantly improve various oxidative damage problems.

Natural Polyphenols and Organic Acids

Oak extract is also abundant in natural polyphenols and organic acids, featuring an elegant and steady natural woody fragrance. These ingredients not only endow the product with a unique natural woody texture, but also exhibit excellent effects on metabolism regulation, mild bacteriostasis and soothing conditioning. They gently nourish and protect the skin and body, bringing multiple maintenance benefits.

3. Appearance and Properties

Color

Conventional-grade oak extract ranges from light brownish yellow to dark brownish yellow; high-purity grade is light pale yellow, and high-precision grade is pale yellowish white, free of impurities and agglomerates.

Form

The product is available in fine powder and concentrated liquid extract. The delicate powder is easy to formulate and suitable for producing dietary supplements, solid functional foods and cosmetic powder raw materials. The liquid extract features higher concentration and fully retained active ingredients, which is more suitable for deep processing scenarios requiring high concentration and high permeability.

Solubility

Conventional oak extract powder has moderate water solubility and achieves better dispersion and dissolution effects in alcohol-based and oil-based systems. Supported by advanced extraction and modification technology, water-soluble oak extract has realized stable mass production, which is compatible with various water-based production systems and fully meets the diversified application needs of different industries.

4. Health Benefits

Antioxidant Protection

As mentioned above, flavonoids, anthocyanins and polyphenols in oak extract possess strong antioxidant capacity. They can effectively eliminate free radicals in the body and on the skin, protect cells from oxidative damage, slow down the aging process of the body and skin, and reduce the risks of skin dullness, aging and sagging as well as physical sub-health problems.

Anti-inflammatory and Soothing Properties

Multiple studies have confirmed that oak extract has remarkable anti-inflammatory and soothing effects. It can effectively relieve superficial skin inflammation, redness and sensitivity, and assist in regulating mild internal inflammation of the body. It plays a positive role in stabilizing the skin barrier, improving skin texture and conditioning metabolic inflammation.

Body Metabolism and Physical & Mental Conditioning

The natural active ingredients in oak exert positive regulatory effects on human metabolism and physical and mental state. They help regulate body circulation, relieve physical fatigue, improve listlessness, stabilize physical functions, and effectively ameliorate sub-health conditions caused by overwork and metabolic disorders.

Metabolic Maintenance and Health Care

The organic acids and polyphenols in oak extract can mildly regulate human metabolism, balance body circulation, promote unobstructed metabolism, and relieve body bloating and fatigue caused by slow metabolism and poor circulation, realizing gentle full-body conditioning and health maintenance.

5. Applications

Dietary Supplements

6. Quality Assurance

Raw Material Procurement

All our oak raw materials are sourced from reliable suppliers complying with Good Agricultural Practices. Raw materials undergo strict manual and mechanical double screening. Only high-quality mature oak materials with fine texture, no mildew, no impurities and no decay are selected to ensure high-quality raw materials, stable ingredients and consistent quality from the source.

Extraction Technology

Our extraction process is multi-layer optimized and upgraded to maximally extract core active ingredients including oak flavonoids, anthocyanins and polyphenols, while completely retaining their molecular structure and biological activity to avoid active ingredient loss. Advanced technologies such as supercritical fluid extraction, low-temperature solvent extraction and spray drying are flexibly adopted according to different product grade requirements to guarantee product purity and quality.

Testing and Analysis

Each batch of oak extract undergoes strict tests on active ingredient content, purity and overall quality. High Performance Liquid Chromatography (HPLC) is applied to accurately determine the content of core components to meet quality standards. Meanwhile, rigorous safety tests on microorganisms, heavy metals and impurities are carried out to eliminate harmful contaminants and ensure product safety and compliance.

7. Packaging and Storage

Packaging

Our oak extract is packed in high-quality sealed containers, which can effectively isolate light, moisture and oxygen erosion and prevent oxidative failure of active ingredients. Powder products are normally packed in food-grade multi-layer composite bags and moisture-proof cardboard drums; liquid extracts are stored in light-proof glass bottles and various eco-friendly sealed containers to ensure quality during transportation and storage.

Storage Conditions

It is recommended to store oak extract in a cool, dry, ventilated and dark place away from direct sunlight. Low-temperature refrigeration at 2°C to 8°C is recommended to maximize the retention of product activity and ensure long-term stable product quality and efficacy.
