N-Lauryl Diethanolamine, also known by its chemical names Dodecanamine, N,N-bis(2-hydroxyethyl) and 2,2′-(Dodecylimino)bisethanol, is a versatile ingredient primarily used in hair conditioning products. This compound is derived from lauryl alcohol, which is a fatty alcohol commonly sourced from coconut oil or palm kernel oil. The “N-Lauryl” part of its name refers to the lauryl group, a 12-carbon chain, while “Diethanolamine” indicates the presence of two ethanolamine groups.
The history of N-Lauryl Diethanolamine in cosmetic products dates back several decades. Initially, it was explored for its surfactant properties, which help in the formation of emulsions by reducing surface tension. Over time, its hair conditioning capabilities were discovered, making it a popular choice in shampoos, conditioners, and other hair care formulations.
The production of N-Lauryl Diethanolamine involves a chemical reaction between lauryl alcohol and diethanolamine. This process typically occurs under controlled conditions to ensure the correct balance and purity of the final product. The resulting compound is a clear to pale yellow liquid that is soluble in water, making it easy to incorporate into various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of N-Lauryl Diethanolamine:
N-Lauryl Diethanolamine is primarily used in cosmetics for its hair conditioning properties. This means that it helps to improve the texture and appearance of hair, making it softer, smoother, and more manageable. When included in hair care products like shampoos and conditioners, it can help to detangle hair, reduce frizz, and add a healthy shine. Essentially, it works to enhance the overall feel and look of your hair, making it easier to style and maintain.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
N-Lauryl Diethanolamine, while beneficial for hair conditioning, does come with some considerations regarding its safety, suitability, and allergenic potential.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of N-Lauryl Diethanolamine during pregnancy are lacking. It is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from N-Lauryl Diethanolamine are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage.
In terms of comedogenicity, N-Lauryl Diethanolamine has a rating of 2 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This means it has a low to moderate likelihood of clogging pores, which could be a concern for individuals prone to acne, blemishes, or breakouts.
