Ever wondered what makes your favorite cosmetics so smooth and luxurious? Dive into our in-depth exploration of Stearamide DEA-Distearate, uncovering its creation, benefits, and potential side effects to understand why it's a staple in the beauty industry.

What is Stearamide Dea-Distearate?

Stearamide Dea-Distearate, also known by its chemical name [(1-Oxooctadecyl)imino]diethane-1,2-diyl distearate, is a versatile ingredient commonly found in various cosmetic products. This compound is derived from stearic acid, a fatty acid that is naturally present in animal fats and vegetable oils.

The use of Stearamide Dea-Distearate in cosmetics dates back several decades. Initially, it was introduced as a means to improve the texture and stability of formulations. Over time, its multifunctional properties have made it a staple in many skincare and haircare products. Its ability to act as an opacifying agent, foam booster, and viscosity controller has cemented its place in the cosmetic industry.

The production of Stearamide Dea-Distearate involves a chemical reaction between stearic acid and diethanolamine, followed by esterification with stearic acid. This process results in a compound that can enhance the performance and sensory attributes of cosmetic formulations. The final product is a waxy solid that is easy to incorporate into various types of products, from creams and lotions to shampoos and conditioners.

The Benefits/Uses of Stearamide Dea-Distearate

In this section, we will delve into the officially recognized cosmetic benefits and uses of Stearamide Dea-Distearate:


One of the primary functions of Stearamide Dea-Distearate is its ability to act as an opacifying agent. This means it helps to make cosmetic products less transparent or opaque. In practical terms, this can enhance the visual appeal of products like lotions, creams, and shampoos by giving them a richer, more luxurious appearance. It can also help to mask any unsightly discoloration of the product itself, ensuring a consistent and attractive look.

Foam Boosting

Stearamide Dea-Distearate is also recognized for its foam-boosting properties. This means it can enhance the formation and stability of foam in products like shampoos, body washes, and facial cleansers. A rich, stable foam can improve the user experience by making the product feel more effective and luxurious during application. It also helps to distribute the product more evenly across the skin or hair, ensuring a thorough and satisfying cleanse.

Viscosity Controlling

Another significant benefit of Stearamide Dea-Distearate is its role in controlling the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, this ingredient helps to achieve the desired consistency, making products easier to apply and spread. Whether you prefer a thick, creamy lotion or a light, fluid serum, Stearamide Dea-Distearate can help to create the perfect texture for your needs.

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

Stearamide Dea-Distearate is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.

  • Skin irritation
  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Stearamide Dea-Distearate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.

Side effects and adverse reactions from Stearamide Dea-Distearate are generally uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.

In terms of comedogenicity, Stearamide Dea-Distearate has a rating of 2 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means that while it is relatively low on the scale, it may still cause breakouts or blemishes in individuals who are prone to acne.
