Dea-Oleth-10 Phosphate, also known by its chemical name (Z)-9-Octadecanol, ethoxylated, phosphates, bis(2-hydroxyethyl)ammonium salts (10 mol EO average molar ratio), is a versatile ingredient commonly found in cosmetic products. This compound is primarily sourced from oleth-10, a derivative of oleyl alcohol, which is then ethoxylated and combined with phosphates and bis(2-hydroxyethyl)ammonium salts. The “10 mol EO” indicates that, on average, ten units of ethylene oxide are added per molecule during the ethoxylation process.
Historically, the use of ethoxylated compounds in cosmetics dates back several decades, as they were discovered to enhance the performance of various formulations. Dea-Oleth-10 Phosphate emerged as a popular choice due to its dual functionality as both a cleansing and emulsifying agent. Its ability to effectively break down oils and dirt while also helping to blend water and oil-based ingredients made it a valuable addition to many skincare and haircare products.
The production of Dea-Oleth-10 Phosphate involves a multi-step chemical process. Initially, oleyl alcohol is subjected to ethoxylation, where ethylene oxide is added to the alcohol under controlled conditions. This results in the formation of oleth-10. Subsequently, this ethoxylated compound is reacted with phosphoric acid and bis(2-hydroxyethyl)amine to produce the final phosphate salt. This intricate synthesis ensures that the ingredient possesses the desired properties for use in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Dea-Oleth-10 Phosphate:
Dea-Oleth-10 Phosphate is primarily known for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin. When included in a cosmetic product, it acts as a surfactant, which is a fancy way of saying it helps water to mix with oil and dirt so they can be rinsed away. This makes it an effective ingredient in products like facial cleansers, body washes, and shampoos. Essentially, it helps to keep your skin and hair clean by ensuring that unwanted substances are easily washed off.
Another key benefit of Dea-Oleth-10 Phosphate is its emulsifying capability. In simple terms, this means it helps to blend ingredients that typically don’t mix well together, like oil and water. This is crucial for creating stable and consistent cosmetic formulations. For example, in lotions and creams, it ensures that the product remains smooth and doesn’t separate into oily and watery layers. This not only improves the texture and feel of the product but also ensures that the active ingredients are evenly distributed, enhancing the overall effectiveness of the cosmetic product.
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).
Dea-Oleth-10 Phosphate is generally considered safe for use in cosmetic products, but like any ingredient, it can have potential side effects and considerations that users should be aware of.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Dea-Oleth-10 Phosphate during pregnancy are lacking. Therefore, it is recommended that pregnant or breastfeeding women consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Dea-Oleth-10 Phosphate are uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, Dea-Oleth-10 Phosphate has a rating of 2 on a scale of 0 to 5. This means it has a low to moderate likelihood of clogging pores. Individuals who are prone to acne, blemishes, or breakouts should be cautious and monitor their skin’s response when using products containing this ingredient.
