PEG-2 Dirosinate, also known as Resin acids and rosin acids, diesters with .alpha.-hydro-.omega.-hydroxypoly(oxy-1,2-ethanediyl) (2 mol EO average molar ratio), is a synthetic ingredient commonly used in the cosmetic industry. This compound is derived from rosin, a natural resin obtained from pine trees and other conifers. The “PEG” in its name stands for polyethylene glycol, which is a polyether compound that is widely used in various pharmaceutical and cosmetic formulations.
The history of PEG-2 Dirosinate in cosmetics dates back to the mid-20th century when scientists began exploring the potential of polyethylene glycol derivatives for their emollient and emulsifying properties. Over time, PEG-2 Dirosinate was developed as a versatile ingredient that could serve multiple functions in skincare and personal care products.
The production of PEG-2 Dirosinate involves a chemical reaction between rosin acids and polyethylene glycol. This process creates diesters, which are compounds formed by the reaction of two molecules of an acid with one molecule of an alcohol. The resulting product is a stable, water-soluble ingredient that can be easily incorporated into various formulations. The “2 mol EO” in its name indicates that, on average, two molecules of ethylene oxide are used in the reaction, giving the compound its unique properties.
In this section, we will delve into the officially recognized cosmetic benefits and uses of PEG-2 Dirosinate:
PEG-2 Dirosinate is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When included in cosmetic formulations, it works to keep your skin feeling soft, smooth, and hydrated. Essentially, it acts as a moisturizer, ensuring that your skin doesn’t dry out and remains supple. This can be particularly beneficial in products like lotions, creams, and serums where maintaining skin hydration is key.
Another important function of PEG-2 Dirosinate is its ability to control the viscosity of cosmetic products. Viscosity refers to the thickness or thinness of a liquid. By adjusting the viscosity, PEG-2 Dirosinate ensures that products have the right consistency, making them easier to apply and more pleasant to use. For instance, it can make a lotion feel more luxurious and less runny, or ensure that a cream is thick enough to stay on your skin without dripping. This function is crucial in a wide range of products, from shampoos and conditioners to facial cleansers and body washes.
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).
PEG-2 Dirosinate is generally considered safe for use in cosmetic products, but as with any ingredient, it is important to be aware of potential side effects and other considerations.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of PEG-2 Dirosinate 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.
Side effects and adverse reactions from PEG-2 Dirosinate are generally uncommon. However, as with any cosmetic ingredient, it is recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, PEG-2 Dirosinate has a rating of 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating indicates that it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
