Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer: What Is It, Cosmetic Uses, Benefits & Side Effects

This article was last updated on: March 26, 2024

Understanding the world of cosmetics can often feel like trying to decipher a foreign language, especially when you’re faced with a long list of scientific names on the back of your favorite product.

One such ingredient that you might have come across is Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer. It’s a mouthful, isn’t it?

In this article, we’re going to dive deep into what Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is, why it’s used in cosmetic products, and what you need to know about its benefits and potential side effects.

What is Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer?

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, also known by its trade name of SEPINOV™ WEO, is a copolymer of sodium hydroxyethyl acrylate and acryloyldimethyl taurate monomers. This ingredient is commonly found in the cosmetic industry, particularly in skincare and makeup products.

It’s created through a process of polymerization, where the sodium hydroxyethyl acrylate and acryloyldimethyl taurate monomers are combined to form a larger, more complex structure. The primary role of this ingredient in cosmetic products is to stabilize emulsions and control viscosity. It works by creating a gel-like network within the product, which helps to maintain its consistency and stability.

Due to this ingredient being “non-active” (i.e., it doesn’t directly benefit your skin), you won’t find Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer sold as a standalone product. Instead, it’s usually part of a wider formulation of ingredients within a product, contributing to the overall texture and performance of the product.

Who Can Use Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer?

This ingredient is generally suitable for all skin types. It’s not known to be irritating or sensitizing, making it a good choice even for those with sensitive skin.

As for vegans and vegetarians, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is a synthetic ingredient, meaning it’s not derived from animals or animal by-products. So yes, it’s suitable for those following a vegan or vegetarian lifestyle.

For pregnant or breastfeeding women, there’s no specific information suggesting that this ingredient should be avoided. However, as with any cosmetic ingredient, it’s always a good idea to consult with a healthcare provider if you have any concerns.

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer’s Cosmetic Benefits/Uses

The benefits and uses listed in this section are strictly the cosmetic benefits and uses of Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer. This ingredient may have applications in multiple different industries, which are beyond the scope of this article. The benefits are based on the official functions of this ingredient as an emulsion stabilizer and viscosity controller.

  • Emulsion Stabilizing: Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer plays a crucial role in stabilizing emulsions in cosmetic products. Emulsions are mixtures of water and oil, which naturally tend to separate. This ingredient helps to keep these mixtures stable, preventing the separation of the oil and water components. This is particularly important in products like creams and lotions, which rely on a stable emulsion to maintain their texture and efficacy. By stabilizing the emulsion it ensures that the product remains consistent in texture and performance throughout its lifespan.
  • Viscosity Controlling: Another significant benefit of Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is its ability to control the viscosity of cosmetic products. Viscosity refers to a fluid’s resistance to flow. In cosmetics, controlling the viscosity is essential to achieve the desired consistency and feel of the product. Too low viscosity can make a product runny and difficult to apply, while too high viscosity can make it thick and hard to spread. Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer helps to achieve the right balance, ensuring the product is easy to apply and leaves a pleasant feel on the skin.

Potential Side Effects/Adverse Reactions

Like any ingredient, the topical application of Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer can result in different side effects and reactions, depending on the individual. It’s important to remember that everyone’s skin is unique and may react differently to the same product or ingredient.

Some potential side effects associated with the topical application of this ingredient include:

  • Redness
  • Itching
  • Burning sensation
  • Skin irritation
  • Allergic reactions

If you experience any of these side effects while using a product containing Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, it’s recommended to discontinue use immediately and consult with a healthcare professional or dermatologist.

Adverse reactions to Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer are generally rare, but they can occur, especially in individuals with sensitive skin or those who are allergic to the ingredient.

Before incorporating a new product into your skincare routine, it’s always a good idea to perform a patch test. This can help you determine how your skin will react to the product and prevent potential adverse reactions. Remember, it’s always better to be safe than sorry when it comes to your skin’s health.

Comedogenic Rating

Comedogenicity refers to the potential of a substance to cause comedones, which are skin blemishes often associated with acne. These are caused by the clogging of pores by certain cosmetic ingredients. The comedogenic scale ranges from 0 to 5, with 0 being non-comedogenic (will not clog pores) and 5 being highly comedogenic (will clog pores and likely cause acne).

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer has a comedogenic rating of 0. This means that it is non-comedogenic and does not clog pores or contribute to acne breakouts. This rating is based on the molecular structure of the ingredient, which is too large to penetrate the pores and cause blockages.

Therefore, it is suitable for individuals who are prone to acne or breakouts, as it will not contribute to these skin issues.

Conclusion

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer serves two main functions in cosmetics: it acts as an emulsion stabilizer and controls viscosity. As an emulsion stabilizer, it helps to maintain a uniform dispersion of two or more immiscible substances in a product. As a viscosity controller, it alters the thickness of cosmetic products, making them more or less fluid.

Despite its positive non-active benefits, it is not as widely recognized or used as some other cosmetic ingredients (possible due to it’s ridiculously complex and consumer-unfriendly name). However, it is similar to other polymers used in cosmetics for its stabilizing and viscosity-controlling properties.

In terms of safety, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is generally considered safe for use in cosmetics. Its low comedogenic rating means it is unlikely to cause skin irritation or acne breakouts, making it a suitable ingredient for a wide range of skin types.
