Mea-Ppg-8-Steareth-7 Carboxylate, also known by its more technical name, Poly(oxy-2,1-propanediyl)poly(oxy-1,2-ethanediyl), .alpha.-octadecyl-.omega.-carboxymethoxy-, 2-aminoethanol salts (8 mol PO, 6 mol EO average molar ratio), is a synthetic compound commonly used in cosmetic formulations. This ingredient is primarily sourced from petrochemical derivatives and is a result of complex chemical reactions involving propylene oxide (PO) and ethylene oxide (EO).
The history of Mea-Ppg-8-Steareth-7 Carboxylate in cosmetics dates back to the mid-20th century when the demand for more effective and stable cleansing and emulsifying agents began to rise. Chemists and formulators were on the lookout for ingredients that could enhance the texture and performance of skincare and haircare products. Through extensive research and development, this compound was identified as a versatile and effective ingredient, leading to its widespread adoption in the beauty industry.
The production of Mea-Ppg-8-Steareth-7 Carboxylate involves a multi-step chemical process. Initially, propylene oxide and ethylene oxide are polymerized to form a block copolymer. This copolymer is then reacted with stearic acid to introduce the octadecyl group. Finally, the resulting compound is neutralized with 2-aminoethanol to form the carboxylate salt. This intricate process ensures that the final product is both effective and safe for use in various cosmetic applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Mea-Ppg-8-Steareth-7 Carboxylate:
One of the primary benefits of Mea-Ppg-8-Steareth-7 Carboxylate is its cleansing ability. This ingredient acts as a surfactant, which means it helps to remove dirt, oil, and impurities from the skin or hair. When included in products like shampoos, facial cleansers, or body washes, it aids in creating a lather that effectively lifts away unwanted substances, leaving the skin or hair feeling clean and refreshed.
Another significant benefit of Mea-Ppg-8-Steareth-7 Carboxylate is its emulsifying property. In cosmetic formulations, emulsifiers are crucial for blending water and oil components together, ensuring a stable and homogenous mixture. This is particularly important in products like lotions, creams, and serums, where a smooth and consistent texture is desired. By keeping the ingredients well-mixed, this emulsifier helps to enhance the overall performance and feel of the product on 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).
Mea-Ppg-8-Steareth-7 Carboxylate is generally considered safe for use in cosmetic products, but like any ingredient, it may cause side effects in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Mea-Ppg-8-Steareth-7 Carboxylate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Mea-Ppg-8-Steareth-7 Carboxylate are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage.
In terms of comedogenicity, Mea-Ppg-8-Steareth-7 Carboxylate 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 means it is unlikely to clog pores and cause acne or breakouts, making it generally suitable for individuals prone to blemishes.
