About this ingredient
Olus Oil (from Latin olus – vegetable) is a generic INCI for a blend of vegetable oils. The exact composition is not disclosed; common components include soybean, cottonseed, rapeseed, and sunflower oils combined according to the manufacturer's purchasing economics. INCI: Olus Oil. Alternative synonyms are Vegetable Oil and Huile Vegetale. In formulas it works as a baseline liquid emollient. It gives strong occlusion and a dense after-feel. It appears in creams for dry skin, body balms, and products positioned as nourishing. Use levels run from 1% to 30%. Pregnancy safety. Topical use is safe. Systemic absorption through intact skin is minimal. No teratogenic effects in the literature. Skin tolerance. For most users the irritation and allergen profile is low. Acne-prone skin may have issues – some source oils (for example soybean at high concentrations) score 3 on the comedogenic scale. The main downside is INCI opacity. In patients with confirmed IgE allergy to soy or cotton, Olus Oil is risky: there is no way to know which fraction is in a specific batch. For sensitive skin and allergies, formulas with specific INCI such as Helianthus Annuus Seed Oil or Sesamum Indicum Seed Oil are preferable. No standalone active effects. This is an occlusion and texture component. Skin benefit comes mainly from physically lowering TEWL, not from biological activity.
