shale oil

Description

Shale oil, also known as kerogen oil, is a controversial ingredient in skincare derived from sedimentary rock formations. This fossil fuel-based substance is extracted through a process called retorting, which involves heating oil shale to high temperatures. The resulting oil contains a complex mixture of hydrocarbons, including alkanes, cycloalkanes, and aromatic compounds.

In skincare formulations, shale oil is primarily valued for its emollient properties and potential anti-inflammatory effects. It forms a protective barrier on the skin, helping to lock in moisture and prevent transepidermal water loss. Some studies suggest that shale oil may have antimicrobial and wound-healing properties, making it potentially beneficial for treating conditions like eczema and psoriasis.

However, the use of shale oil in skincare is controversial due to environmental concerns associated with its extraction and potential contamination with heavy metals or other impurities. Additionally, its petroleum origin raises questions about long-term safety and sustainability. While some products containing shale oil claim to be purified and refined, it's essential to consider alternative, more environmentally friendly ingredients that offer similar benefits without the associated risks and ethical concerns.
