PPG-7, also known as Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-hydro-.omega.-hydroxy- (7 mol PO average molar ratio), is a versatile ingredient commonly found in various cosmetic products. In the world of cosmetics, it is primarily recognized for its roles as a skin conditioning agent and a solvent. This ingredient is part of the larger family of polypropylene glycols, which are synthetic polymers made from propylene oxide.
The history of PPG-7 in cosmetics dates back to the mid-20th century when advancements in polymer chemistry allowed for the creation of more sophisticated and effective synthetic ingredients. Its ability to enhance the texture and feel of cosmetic formulations quickly made it a popular choice among manufacturers. Over the years, PPG-7 has been refined and optimized to meet the evolving needs of the beauty industry.
PPG-7 is synthesized through a chemical process known as polymerization, where propylene oxide molecules are linked together to form a polymer chain. The “7 mol PO average molar ratio” indicates that, on average, seven units of propylene oxide are incorporated into each molecule of PPG-7. This specific configuration gives PPG-7 its unique properties, making it an effective and reliable ingredient in various cosmetic applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Ppg-7:
Ppg-7 is known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When used in cosmetic products, Ppg-7 can help to soften and smooth the skin, making it feel more supple and hydrated. This is particularly beneficial in lotions, creams, and other skincare products where maintaining skin moisture and texture is key. Essentially, it helps your skin look and feel healthier by improving its overall condition.
Another important function of Ppg-7 is its role as a solvent. In the world of cosmetics, a solvent is a substance that can dissolve other ingredients to form a solution. Ppg-7 helps to dissolve other ingredients in a formulation, ensuring that they are evenly distributed throughout the product. This is crucial for the effectiveness of many cosmetic products, as it ensures that the active ingredients are delivered uniformly to the skin. So, when you apply a product containing Ppg-7, you can be confident that you’re getting the full benefit of all the ingredients it contains.
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).
PPG-7 is generally considered safe for use in cosmetic products, with a low potential for causing irritation or allergic reactions. However, as with any ingredient, some individuals may experience side effects. The potential side effects of topical application of PPG-7 include:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of PPG-7 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 PPG-7 are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there is no sensitivity or adverse reaction to the ingredient.
PPG-7 has a comedogenicity rating of 1, which means it is considered to have a very low likelihood of clogging pores. This makes it a suitable ingredient for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to exacerbate these conditions.
