What is Polyglyceryl-2 Diisostearate/Ipdi Copolymer?
Polyglyceryl-2 Diisostearate/Ipdi Copolymer is a synthetic ingredient commonly found in various cosmetic products. This compound is a copolymer, meaning it is made from two different monomers: isophorone diisocyanate (IPDI) and the 16-methylheptadecanoate diester of diglycerol monomers. In simpler terms, it’s a complex molecule designed to perform specific functions in cosmetic formulations.
This ingredient is also known by other names, such as Polyglyceryl-2 Diisostearate/IPDI Copolymer, which you might spot on product labels. Its primary roles in cosmetics, as listed in the CosIng Database, include binding, emulsion stabilizing, and film forming. These functions make it a versatile addition to many skincare and makeup products.
The history of Polyglyceryl-2 Diisostearate/Ipdi Copolymer in cosmetics is relatively recent, emerging as a result of advancements in polymer chemistry and the growing demand for multifunctional ingredients. As cosmetic formulations have become more sophisticated, the need for ingredients that can enhance texture, stability, and performance has driven the development and adoption of such copolymers.
The production process of Polyglyceryl-2 Diisostearate/Ipdi Copolymer involves a series of chemical reactions. Initially, isophorone diisocyanate reacts with diglycerol, a molecule derived from glycerin, to form a pre-polymer. This pre-polymer is then further reacted with 16-methylheptadecanoate diester to create the final copolymer. The result is a stable, multifunctional ingredient that can improve the consistency and longevity of cosmetic products.
The Benefits/Uses of Polyglyceryl-2 Diisostearate/Ipdi Copolymer
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-2 Diisostearate/Ipdi Copolymer:
Binding
One of the primary functions of Polyglyceryl-2 Diisostearate/Ipdi Copolymer is its binding capability. In the world of cosmetics, binding refers to the ingredient’s ability to hold together the various components of a product. This ensures that the product maintains its consistency and effectiveness throughout its shelf life. For example, in a powder foundation, this ingredient helps keep the powder particles together, preventing them from separating and ensuring a smooth application.
Emulsion Stabilising
Another significant benefit of Polyglyceryl-2 Diisostearate/Ipdi Copolymer is its role in emulsion stabilization. Emulsions are mixtures of oil and water, which naturally tend to separate. This ingredient helps to stabilize these mixtures, ensuring that the oil and water components remain evenly distributed. This is particularly important in products like lotions and creams, where a consistent texture and performance are crucial for user satisfaction.
Film Forming
Polyglyceryl-2 Diisostearate/Ipdi Copolymer also excels in film forming. This means it can create a thin, continuous layer on the skin or hair when applied. This film can provide various benefits, such as enhancing the product’s durability, improving its water resistance, and delivering a smooth, even finish. For instance, in a sunscreen, this film-forming property helps the product stay on the skin longer, providing more effective protection against UV rays.
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).
Potential Side Effects & Other Considerations
Polyglyceryl-2 Diisostearate/Ipdi Copolymer 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.
- Skin irritation: Some individuals may experience mild irritation, especially if they have sensitive skin.
- Allergic reactions: Although rare, allergic reactions such as redness, itching, or swelling can occur.
- Contact dermatitis: In very rare cases, contact dermatitis may develop, characterized by a rash or inflammation.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyglyceryl-2 Diisostearate/Ipdi Copolymer during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Polyglyceryl-2 Diisostearate/Ipdi Copolymer are uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure personal tolerance.
In terms of comedogenicity, Polyglyceryl-2 Diisostearate/Ipdi Copolymer 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.
