Rosehip Oil: Nature’s Potent Elixir for Health and Beauty

Rosehip oil, extracted from the seeds and pulp of the Rosa canina fruit, is a golden – orange, cold – pressed oil celebrated for its rich composition of essential fatty acids, vitamins, and antioxidants. Comprising high levels of linoleic acid (omega – 6), alpha – linolenic acid (omega – 3), and a unique form of trans – retinoic acid (a precursor to vitamin A), it offers remarkable regenerative, moisturizing, and anti – inflammatory properties. This natural oil has been used for centuries in traditional medicine and skincare, making it a sought – after ingredient in modern cosmetics, nutraceuticals, and pharmaceutical products.

3. Product Source

3.1 Botanical Origin

Rosehip oil is derived from the fruits of Rosa canina, commonly known as the dog rose, which thrives in temperate regions such as Chile, South Africa, and Europe. We source rosehips from certified organic farms, ensuring that the fruits are free from pesticides and synthetic fertilizers. The optimal harvest time is in late autumn when the fruits are fully ripe, maximizing the oil’s nutrient content.

3.2 Extraction Process

The production of rosehip oil begins with the careful harvesting and cleaning of rosehip fruits. The fruits are then dried to reduce moisture content, after which the seeds and pulp are separated. Using a cold – pressing method, the oil is extracted without the use of heat or chemicals, preserving its bioactive compounds. This gentle extraction process ensures that the oil retains its full range of beneficial properties, including vitamins A, C, and E, as well as essential fatty acids.

8. Production Process

8.1 Raw Material Inspection

Rosehip fruits are carefully inspected upon arrival at our facilities. They are tested for quality, including moisture content, maturity, and the presence of contaminants. Only fruits that meet our strict standards are selected for further processing.

8.2 Drying and Separation

The selected rosehip fruits are dried to an optimal moisture level. After drying, the seeds and pulp are separated using mechanical methods. The seeds and pulp, which contain the valuable oil, are then prepared for extraction.

8.3 Cold – Pressing

The separated seeds and pulp are cold – pressed to extract the rosehip oil. This low – temperature process ensures that the oil’s nutritional components and bioactive compounds remain intact.

8.4 Filtration and Purification

The extracted crude oil is filtered to remove any solid particles or impurities. It then undergoes further purification processes to meet our high – quality standards, including removing any residual odors or flavors.

8.5 Quality Control Testing

Each batch of rosehip oil is rigorously tested for purity, composition, and safety. Tests include analysis of fatty acid profiles, vitamin content, pesticide residues, heavy metals, and microbial contamination. Only batches that pass all tests are approved for packaging and distribution.

9. Application Scenarios
