Oleic Acid 100 ml

How oleic acid supports emulsions, soaps, and industrial formulations

Oleic acid is an unsaturated fatty acid widely used as a functional ingredient in skincare formulations, liquid soap production, and various industrial applications. It belongs to the Acids, Salts, Alcohols, and Alkalis section, since the neutralization reaction between the acid and an alkali is the foundation of many soap-making and emulsifying processes. The 100 ml packaging is well suited for home formulation, small test batches, and trial runs when evaluating a new recipe before scaling up to larger production.

The strongest global demand for oleic acid comes from the cosmetic industry, where it acts as an emollient that softens skin and supports the lipid barrier, as well as a co-emulsifier in creams, balms, and body oils. When combined with alkalis, the acid forms an oleate salt - a mild soap base used in liquid hand soaps, shower gels, and facial cleansers. In such formulations it is often paired with other acids from the same category, for example citric acid, which adjusts the final pH and helps stabilize the emulsion structure.

Beyond cosmetics, oleic acid serves as a raw material in the chemical industry for producing surfactants, lubricants, textile auxiliaries, and corrosion inhibitors used in metalworking fluids. In pharmaceutical manufacturing it is incorporated into ointment and cream bases because it improves the penetration of other active ingredients through the skin. In the food sector, the acid and its derivatives are used as emulsifiers and processing lubricants for equipment.

When building a formulation, the acid is typically introduced into the oil phase at 60-70 degrees Celsius, after which the oil phase is combined with the water phase to form a stable emulsion. Recommended usage levels in creams and lotions range from 2 to 8 percent of total formula weight, while in soap bases the proportion can be higher depending on the desired lathering profile. The ingredient blends well with vegetable oils, waxes, lanolin, and other fatty acids, as well as with alkaline components from the same section, including boric acid, which is sometimes used for preservation or pH adjustment in finished products.

Store the acid in a tightly sealed container, in a cool dark place away from direct sunlight and heat sources to prevent oxidation. Slight darkening may occur over long storage periods without affecting its functional properties. To boost soothing and restorative effects, formulators sometimes combine it with plant-derived actives such as glycyrrhizic acid, which pairs well with fatty acids in formulations designed for sensitive skin.

Nourishing body butter with oleic acid

Oleic acid 6 ml

Shea butter 20 g

Cocoa butter 10 g

Sweet almond oil 15 ml

Emulsifying wax 8 g

Distilled water 100 ml

Glycerin 4 ml

Preservative 1 ml

Combine the shea butter, cocoa butter, almond oil, emulsifying wax, and oleic acid in a heatproof container and melt over a water bath at 70 degrees Celsius. Separately heat the water with glycerin to the same temperature, then slowly pour it into the oil phase while stirring continuously until a smooth emulsion forms. Cool the mixture to 40 degrees, add the preservative, mix thoroughly, and transfer into clean jars for storage.
