Undecyleneth-6 is a versatile ingredient used in the cosmetic industry. It is primarily derived from castor oil and is a member of the polyethylene glycol (PEG) family. This ingredient is also referred to as PEG-6 Undecylenate in some contexts.
The history of Undecyleneth-6 in cosmetics dates back to the mid-20th century when the search for effective antimicrobial and emulsifying agents led to the exploration of various natural and synthetic compounds. Over time, its unique properties made it a staple in formulations aimed at cleansing and protecting the skin.
The production of Undecyleneth-6 involves a chemical process known as ethoxylation, where ethylene oxide is added to undecylenic acid, a substance derived from castor oil. This process results in a compound that has both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties, making it an excellent emulsifier and cleanser. The “6 mol EO” in its name indicates that, on average, six units of ethylene oxide are added per molecule of undecylenic acid, giving it its specific characteristics and functionality in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Undecyleneth-6:
Undecyleneth-6 has antimicrobial properties, which means it helps to inhibit the growth of microorganisms such as bacteria and fungi. This is particularly beneficial in cosmetic products as it helps to preserve the product, ensuring it remains safe and effective for use over time. Additionally, its antimicrobial action can help to keep the skin clean and reduce the risk of infections, making it a valuable ingredient in products like cleansers and lotions.
As a cleansing agent, Undecyleneth-6 helps to remove dirt, oil, and impurities from the skin. This makes it an excellent ingredient in facial cleansers, body washes, and shampoos. By effectively breaking down and washing away unwanted substances, it helps to keep the skin and hair clean, fresh, and healthy-looking. This cleansing action can also help to prevent clogged pores and reduce the occurrence of acne and other skin issues.
Undecyleneth-6 acts as an emulsifier, which means it helps to blend water and oil-based ingredients together. This is crucial in the formulation of many cosmetic products, such as creams, lotions, and serums, where a stable and uniform mixture is needed. By ensuring that the ingredients are well-mixed and do not separate, it enhances the texture and consistency of the product, making it easier to apply and more pleasant to use.
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).
Undecyleneth-6, like many cosmetic ingredients, has been evaluated for safety and suitability in topical applications. Generally, it is considered safe for use in cosmetics, but as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Undecyleneth-6 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Undecyleneth-6 are generally uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure personal tolerance.
In terms of comedogenicity, Undecyleneth-6 is rated as a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
