Ever wondered what gives your favorite cosmetics their silky texture and luxurious feel? Dive into our in-depth exploration of Lauramide/Myristamide DEA, uncovering its creation, benefits, and potential side effects to help you make informed beauty choices.

What Is Lauramide/Myristamide Dea?

Lauramide/Myristamide DEA, also known as Amides, C12-14, N,N-bis(hydroxyethyl), is a versatile ingredient commonly found in a variety of cosmetic and personal care products. This ingredient is derived from fatty acids, specifically lauric acid and myristic acid, which are typically sourced from coconut oil or palm kernel oil. Chemically, it belongs to a class of compounds known as amides, which are formed when an amine reacts with a carboxylic acid.

The use of Lauramide/Myristamide DEA in cosmetics dates back several decades. Initially, it was introduced as a means to enhance the performance of cleansing products. Over time, its multifunctional properties made it a staple in formulations ranging from shampoos and body washes to facial cleansers and even some lotions. Its ability to improve the texture and efficacy of these products has solidified its place in the cosmetic industry.

The production process of Lauramide/Myristamide DEA involves a reaction between diethanolamine (DEA) and fatty acids derived from natural oils. This reaction results in the formation of a compound that is both hydrophilic (water-attracting) and lipophilic (oil-attracting), making it an excellent emulsifier and surfactant. This dual affinity allows it to effectively break down oils and dirt, making it easier to rinse them away, which is why it is so commonly used in cleansing products.

The Benefits/Uses of Lauramide/Myristamide Dea

In this section, we will delve into the officially recognized cosmetic benefits and uses of Lauramide/Myristamide Dea:


Lauramide/Myristamide Dea helps to reduce static electricity in hair and skin products. This means that it can help prevent your hair from standing on end or becoming frizzy, especially in dry or windy conditions. By neutralizing the electrical charges, it keeps your hair smooth and manageable.


This ingredient is effective at removing dirt, oil, and other impurities from the skin and hair. When included in shampoos, body washes, and facial cleansers, Lauramide/Myristamide Dea helps to ensure that your skin and hair are thoroughly cleaned, leaving you feeling fresh and rejuvenated.

Foam Boosting

Lauramide/Myristamide Dea enhances the foaming properties of cleansing products. This means that when you use a shampoo or body wash containing this ingredient, you’ll get a rich, luxurious lather that makes the product easier to spread and more enjoyable to use. A good foam can also help to lift dirt and oils more effectively.

Viscosity Controlling

This ingredient helps to control the thickness or thinness of cosmetic products. By adjusting the viscosity, Lauramide/Myristamide Dea ensures that products have the right consistency for easy application. Whether you prefer a thick, creamy lotion or a light, fluid serum, this ingredient helps to achieve the desired texture.

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).

Potential Side Effects & Other Considerations

Lauramide/Myristamide DEA, while beneficial for its antistatic, cleansing, foam boosting, and viscosity controlling properties, may have some potential side effects when applied topically. It is important to be aware of these to make informed decisions about its use in cosmetic products.

  • Skin irritation
  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Lauramide/Myristamide DEA during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Lauramide/Myristamide DEA are generally uncommon, but they can occur. To minimize the risk of irritation or allergic reactions, it is recommended to conduct a patch test before widespread usage of any product containing this ingredient.

In terms of comedogenicity, Lauramide/Myristamide DEA 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 potential to clog pores. Individuals who are prone to acne, blemishes, or breakouts should consider this rating when choosing products containing this ingredient.
