Disodium Ricinoleamido MEA Sulfosuccinate is a chemical compound, disodium salt of butandioic acid.

The name describes the structure of the molecule:

• "Disodium" indicates the presence of two sodium ions in the molecule.
• "Ricinoleamido" derives from ricinoleic acid, a fatty acid found in castor oil.
• "MEA" stands for Monoethanolamine, a compound used to form surfactants.
• "Sulfosuccinate" indicates that the molecule is a type of surfactant known as a sulfosuccinate.

Description of raw materials used in production and their functions.

• Castor oil. A vegetable oil derived from the seeds of the castor plant. It is the source of the ricinoleamido group.
• MEA (Monoethanolamine). A tertiary amine used as an intermediate in chemical synthesis.
• Sulfosuccinic acid. A bifunctional acid providing the sulfosuccinate group.

Step-by-step summary of industrial chemical synthesis process.

• Derivation of castor oil. Castor oil is processed to yield ricinoleamido.
• Reaction with MEA. The ricinoleamido is reacted with monoethanolamine to form ricinoleamido MEA.
• Sulfonation. The ricinoleamido MEA intermediate is then sulfonated with sulfosuccinic acid to form the final product, disodium ricinoleamido MEA sulfosuccinate.
• Purification. The reaction mixture is purified to remove any impurities, and the final product is isolated.

What it is for and where

Cosmetics

Cleansing agent. Ingredient that cleanses skin without exploiting the surface-active properties that produce a lowering of the surface tension of the stratum corneum. 

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.

Surfactant - Hydrotrope (solubilizing agents).  It has the property of facilitating the miscibility of other compounds that are poorly soluble in water and does not form micelles in the solubilisation process, even with a chemical reaction of complexation or molecular aggregation. The two fundamental solubilisation factors are the hydrotropic-solute association mediated by the depression of water activity and ionic dissociation.

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities. 

Commercial Applications

Cosmetics and Personal Care. Disodium Ricinoleamido MEA Sulfosuccinate is commonly used as a surfactant in products like shampoos, body washes, and other skin care products. It helps in enhancing foam formation and the consistency of products.

Household Cleaning. It can be found in some cleaning agents due to its cleansing and foaming properties.
