Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer is a mouthful, but it’s essentially a copolymer derived from dilinoleic acid and a blend of isostearic and stearic acids with polyglycerin-3. In simpler terms, it’s a complex ingredient that combines fatty acids and glycerin derivatives to create a multifunctional compound used in cosmetics. You might also see it listed under other names or abbreviations in ingredient lists, but its core composition remains the same.
The history of this ingredient in cosmetics is relatively modern, emerging as the beauty industry sought more sophisticated and multifunctional ingredients. Initially, simpler emulsifiers and conditioning agents were used, but as formulations became more advanced, the need for ingredients that could offer multiple benefits grew. This led to the development of more complex copolymers like Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer, which can provide skin conditioning, protection, and viscosity control all in one.
The production process involves a series of chemical reactions. First, dilinoleic acid is polymerized, and then it is reacted with a mixture of isostearic and stearic acids. This mixture is then esterified with polyglycerin-3, resulting in the final copolymer. This process ensures that the ingredient has the right balance of hydrophilic (water-attracting) and lipophilic (oil-attracting) properties, making it highly effective in various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer:
This ingredient is known for its skin conditioning properties. In simple terms, it helps to keep your skin feeling soft, smooth, and hydrated. When used in cosmetic products, it works to improve the overall texture and appearance of your skin, making it feel more supple and less dry. This is particularly beneficial for those with dry or sensitive skin, as it helps to maintain the skin’s natural moisture balance.
Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer also serves as a skin protecting agent. This means it forms a protective barrier on the skin’s surface, shielding it from environmental stressors such as pollution and harsh weather conditions. By doing so, it helps to prevent damage and irritation, keeping your skin healthier and more resilient over time.
Another important function of this ingredient is its ability to control the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, this ingredient ensures that creams, lotions, and other skincare products have the right consistency for easy application and absorption. This makes the products more effective and pleasant to use, enhancing the overall user experience.
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).
Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer is generally considered safe for use in cosmetic products. It is suitable for most skin types and has a low allergenic potential. However, as with any ingredient, there are potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer during pregnancy is 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 this ingredient are relatively uncommon. However, as with any new skincare product, it is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer is rated at a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means it has a low likelihood of clogging pores, making it generally suitable for individuals prone to acne, blemishes, or breakouts.
