Sodium/TEA C12-13 Pareth-3 Sulfate is a versatile ingredient commonly found in various cosmetic and personal care products. This compound is essentially a mixture of sodium and triethanolamine (TEA) salts derived from the sulfate ester of C12-13 Pareth-3. The “C12-13” refers to the carbon chain length of the fatty alcohols used in its synthesis, which typically come from natural sources like coconut oil or palm kernel oil. The “Pareth-3” part indicates that the fatty alcohols have been ethoxylated with three units of ethylene oxide, making them more soluble in water.
Historically, the use of sulfate-based surfactants in cosmetics dates back several decades. These compounds gained popularity due to their excellent ability to create lather and effectively cleanse the skin and hair. Sodium/TEA C12-13 Pareth-3 Sulfate emerged as a more specialized variant, designed to offer not just cleansing but also skin conditioning properties. This dual functionality made it a valuable addition to shampoos, body washes, and facial cleansers.
The production of Sodium/TEA C12-13 Pareth-3 Sulfate involves a multi-step chemical process. Initially, fatty alcohols derived from natural oils undergo ethoxylation, where ethylene oxide is added to create ethoxylated alcohols (Pareth-3). These ethoxylated alcohols are then sulfated, typically using sulfur trioxide or chlorosulfonic acid, to form the sulfate ester. Finally, the sulfate ester is neutralized with sodium hydroxide and triethanolamine to produce the final mixture of sodium and TEA salts. This intricate process ensures that the ingredient is both effective and safe for use in various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Sodium/Tea C12-13 Pareth-3 Sulfate:
Sodium/Tea C12-13 Pareth-3 Sulfate is primarily used for its skin conditioning properties. This means that it helps to maintain the skin in good condition. When included in cosmetic formulations, it works to improve the texture and appearance of the skin, making it feel softer, smoother, and more hydrated. This can be particularly beneficial in products like moisturizers, cleansers, and lotions, where the goal is to enhance the overall feel and look of the skin.
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).
Sodium/TEA C12-13 Pareth-3 Sulfate 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.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Sodium/TEA C12-13 Pareth-3 Sulfate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Sodium/TEA C12-13 Pareth-3 Sulfate are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, Sodium/TEA C12-13 Pareth-3 Sulfate has a rating of 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 generally suitable for individuals prone to acne, blemishes, or breakouts.
