What is C14-20 Isoalkylamidopropylethyldimonium Ethosulfate?

C14-20 Isoalkylamidopropylethyldimonium Ethosulfate, also known by its chemical name 1-Propanaminium, N-ethyl-N,N-dimethyl-3-[(1-oxo-C18-22-isoalkyl)amino]-, ethyl sulfate (salt), is a synthetic ingredient commonly found in hair care products. This compound is primarily sourced from fatty acids derived from natural oils, which are then chemically modified to produce the final ingredient. It is often referred to by its shorter name, C14-20 Isoalkylamidopropylethyldimonium Ethosulfate, in ingredient lists on cosmetic products.

The history of C14-20 Isoalkylamidopropylethyldimonium Ethosulfate in cosmetics dates back to the increasing demand for more effective hair conditioning agents. As consumers sought products that could provide better manageability and smoother hair, chemists began to explore various synthetic compounds. This particular ingredient emerged as a popular choice due to its dual functionality as both an antistatic and hair conditioning agent.

The production process of C14-20 Isoalkylamidopropylethyldimonium Ethosulfate involves several steps. Initially, fatty acids are extracted from natural oils such as coconut or palm oil. These fatty acids undergo a series of chemical reactions, including amidation and quaternization, to form the desired compound. The final step involves neutralizing the compound with ethyl sulfate to produce the ethosulfate salt form, which is then purified and incorporated into cosmetic formulations.

The Benefits/Uses of C14-20 Isoalkylamidopropylethyldimonium Ethosulfate
