Ever wondered what makes your favorite skincare products so effective? Dive into the world of AMARANTHETH-20 and discover its transformative role in cosmetics, from its creation to its incredible benefits and potential side effects.

What is Amarantheth-20?

Amarantheth-20 is a versatile cosmetic ingredient derived from the fatty alcohols of Amaranthus Caudatus Seed Oil. Often referred to by its chemical name, polyethylene glycol ether, this ingredient is a product of the reaction between ethylene oxide and the fatty alcohols extracted from the seeds of the Amaranthus Caudatus plant. This process results in a compound that conforms to a specific formula, making it a reliable and consistent ingredient in various cosmetic formulations.

The history of Amarantheth-20 in cosmetics dates back to the increasing demand for plant-based and multifunctional ingredients. Amaranthus Caudatus, commonly known as love-lies-bleeding or tassel flower, has been cultivated for centuries for its nutritional and medicinal properties. The oil extracted from its seeds is rich in essential fatty acids and other beneficial compounds, making it an attractive source for cosmetic applications. Over time, the cosmetic industry recognized the potential of modifying this natural oil to enhance its properties, leading to the development of Amarantheth-20.

The production of Amarantheth-20 involves a chemical process known as ethoxylation. This process starts with the extraction of fatty alcohols from Amaranthus Caudatus Seed Oil. These fatty alcohols are then reacted with ethylene oxide, a process that introduces polyethylene glycol (PEG) chains into the molecule. The number “20” in Amarantheth-20 indicates the average number of ethylene oxide units added to each fatty alcohol molecule. This modification enhances the solubility and functionality of the original fatty alcohols, making Amarantheth-20 an effective cleansing and emulsifying agent in cosmetic products.

The Benefits/Uses of Amarantheth-20

In this section, we will delve into the officially recognized cosmetic benefits and uses of Amarantheth-20:


Amarantheth-20 serves as an effective cleansing agent in cosmetic formulations. This means it helps to remove dirt, oil, and other impurities from the skin. When included in products like facial cleansers, body washes, or shampoos, Amarantheth-20 ensures that your skin and hair are left feeling clean and refreshed. Its ability to bind with impurities and rinse them away with water makes it a valuable ingredient for maintaining hygiene and promoting a clear complexion.


Another key benefit of Amarantheth-20 is its emulsifying property. In simple terms, this means it helps to mix water and oil-based ingredients together, which are typically difficult to combine. This is crucial for the stability and texture of many cosmetic products, such as lotions, creams, and serums. By ensuring that these ingredients blend smoothly, Amarantheth-20 helps to create a consistent and pleasant texture, enhancing the overall user experience. It also ensures that the active ingredients are evenly distributed, providing uniform application and effectiveness.

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

Amarantheth-20 is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to be aware of:

  • Skin irritation
  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Amarantheth-20 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.

Adverse reactions to Amarantheth-20 are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there are no adverse reactions.

Amarantheth-20 has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable ingredient for individuals who are prone to acne, blemishes, or breakouts.
