Soybean oil, extracted from the seeds of Glycine Soja, is a highly stable, clear, liquid vegetable oil that is particularly beneficial in skin care applications. Renowned for its emollient properties, it serves as a natural source of tocopherols and sterols, which are effective in protecting the skin. The oil's rich content of minor lipids and natural antioxidants, such as tocopherols, provides exceptional oxidation stability even under varying temperature conditions. This stability, coupled with its antioxidant capabilities, makes soybean oil an excellent choice for skin-care products, especially those targeted at sensitive and delicate skin, including baby-care formulations. Its ability to combat free radicals addresses skin aging and environmental stress. Moreover, soybean oil integrates smoothly into production processes, exhibits compatibility with other cosmetic ingredients, and enhances formulation properties, offering an opportunity to highlight vitamin E content in final applications. It is particularly suitable for products focused on preventing dehydration and promoting skin moisture balance, addressing concerns of dry and sensitive skin.

A fully dilutable EOs/EOCs (essential oils or their components) microemulsion was prepared, and the effect of soybean oil (SBO) on the formation and dilutability of EO microemulsions was studied. Adding SBO to the oil phase reduced particle size and improved the dilutability of essential oil microemulsions. Changes in viscosity and electrical conductivity indicated transitions of microemulsions from water-in-oil (W/O) to bicontinuous and finally to oil-in-water (O/W) structures. The study found that the microemulsions remained stable at room temperature for over 90 days, as indicated by particle size measurements.
Preparation procedure of EOs/EOCs microemulsions
· Surfactant (Tween 80) and the oil phase were mixed in ratios ranging from 1:1 to 9:1, with the oil phase containing EO/EOC (CBO, eugenol, or thymol) and SBO in ratios of 1:0, 2:1, or 4:1.
· A polar phase, consisting of equal parts water and propylene glycol (PG), was added to the oil/surfactant mixture, resulting in a final concentration between 10% and 90% w/w.
· The mixtures were stirred magnetically until there was no visible change in turbidity, then allowed to equilibrate for at least 24 hours at room temperature (21 °C), with their appearance recorded through photographs.
· Samples that appeared transparent after incubation and were confirmed as isotropic by cross-polarized light microscopy were classified as microemulsions.
What is Soybean Oil, and how is it derived?
Soybean Oil, also known as Glycine Soja Oil, is a clear, liquid vegetable oil derived from the seeds of the Glycine Soja plant. It is noted for its superior stability and is enriched with natural tocopherols and sterols.
What are the primary benefits of using Soybean Oil in skincare?
Soybean Oil is a natural emollient that provides skin-care and protecting properties. It is particularly beneficial for sensitive skin due to its high content of tocopherols, which are potent antioxidants. These antioxidants help protect skin cells from environmental stress and oxidative damage, thereby reducing skin aging and offering photoprotective, repairing, and anti-inflammatory benefits.
How does Soybean Oil benefit sensitive and dry skin?
Soybean Oil is excellent for sensitive and dry skin because of its re-lipidising and moisturizing properties. It helps condition the skin and prevents dehydration, making it ideal for formulations developed for delicate skin, baby-care products, and for providing relief to skin imbalances and premature aging.
Can Soybean Oil be easily incorporated into cosmetic products?
Yes, Soybean Oil is easy to handle during production and shows good compatibility with other cosmetic ingredients. Its formulation and sensory properties make it suitable for use in various skincare products.
What makes Soybean Oil a stable ingredient in formulations?
The superior stability of Soybean Oil is due to its enriched content of minor lipids, natural tocopherols, and sterols. This stability is maintained at different temperatures and is particularly notable for its ability to resist oxidation, making it a reliable ingredient in skincare formulations.
Is Soybean Oil effective against environmental stressors?
Yes, the natural tocopherols present in Soybean Oil act as free radical scavengers, protecting sensitive skin cells against environmental stress. This characteristic helps in ameliorating the oxidative stress response and contributes to overall skin health and resilience.
