What Is Oleic acid?
Oleic acid is a type of oil that is colorless or pale yellow in appearance and has a mild odor. It is found naturally in many plants and is widely used in the production of cosmetics, lotions, and soaps. Oleic acid acts as an emollient to soften and condition the skin, while also working as an emulsifying agent to help mix different ingredients together. In addition to its cosmetic uses, oleic acid can also be used as a food additive or even as an insecticide or herbicide. Elaidic acid is a related molecule that can be made from oleic acid and can be found in certain foods like spinach and celery leaves.
What is the purpose of Oleic acid in personal care products?
It is used for its skin conditioning emollient
and surfactant emulsifying characteristics.
Oleic acid hydrates skin to prevent dryness and helps mix liquids that don't usually mix.
Names and identifiers that we found for this substance include: Oleic Acid, 9-Octadecenoic acid, and (9Z)-Octadec-9-enoic acid.
What Are Skin Conditioning Emollient Ingredients?
Oleic acid has skin conditioning emollient characteristics.
Skin conditioning emollients help improve the skin's texture and appearance while providing it with the necessary hydration to prevent dryness and flakiness. Emollients are lubricants that create a barrier on the skin's surface to trap moisture, which helps prevent dryness and dehydration.
Skin conditioning emollients are commonly found in cosmetics such as moisturizers and lotions, which significantly help maintain healthy and youthful-looking skin. Emollients are typically made from natural oils, such as coconut or jojoba, and can also contain humectants that draw moisture to the skin's surface.
What Are Surfactant Emulsifying Ingredients?
Oleic acid has surfactant emulsifying characteristics.
Surfactant emulsifying ingredients helps mix two liquids that do not usually mix well by reducing the surface tension of the ingredients. The emulsification process involves suspending or dispersing one liquid in a second liquid, such as oil in water or vice versa. However, these two liquids have different properties that cause them to repel each other and not mix. This is where surfactants come in, as they can reduce the liquids' surface tension and allow them to mix.
Surfactants have two ends: a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. When added to two liquids that do not mix well, the hydrophilic head attaches to the water-based liquid, while the hydrophobic tail attaches to the oil-based liquid. This creates a stable mixture of the two liquids and allows for a smooth and even distribution of ingredients in the cosmetic product.
