Final answer:
The creation of a basic skin cream involves using stearic acid, lanolin, mineral oil, triethanolamine, and water. Each ingredient serves a unique purpose, from restoring skin's moisture, softening the skin, providing a protective barrier to neutralizing other components for better mixing and adjusting the cream's consistency.
Step-by-step explanation:
The process of preparing a basic skin cream involves a few ingredients which include stearic acid, lanolin, mineral oil, triethanolamine, and water. Stearic acid is a fatty acid that helps to restore the skin's moisture and enhance its flexibility. Lanolin is a type of grease from sheep's wool that acts as an emollient, softening and soothing the skin. Mineral oil is a petroleum by-product which provides a protective barrier on the skin, preventing loss of moisture. Triethanolamine serves to neutralize the stearic acid, allowing it to mix with water. Lastly, water helps to provide a suitable consistency for the cream.
