Disodium Cupric Citrate, also known by its chemical name 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, copper (2+) sodium salt (1:1:2), is a compound that has found its niche in the world of cosmetics. This ingredient is primarily sourced from citric acid, a naturally occurring substance found in citrus fruits, and copper, an essential trace mineral. The combination of these elements results in a compound that serves as a light stabilizer in various cosmetic formulations.
The history of Disodium Cupric Citrate in cosmetics is relatively recent, as the industry has continually evolved to incorporate more sophisticated and effective ingredients. Initially, the focus was on using basic compounds for skin and hair care, but as research progressed, the benefits of more complex molecules like Disodium Cupric Citrate became apparent. Its ability to stabilize light-sensitive ingredients and prevent degradation under UV exposure made it a valuable addition to cosmetic products.
The manufacturing process of Disodium Cupric Citrate involves a series of chemical reactions. It starts with the extraction of citric acid from natural sources or through fermentation processes. This citric acid is then reacted with copper salts and sodium hydroxide under controlled conditions to form the final compound. The result is a stable, water-soluble ingredient that can be easily incorporated into various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Disodium Cupric Citrate:
Disodium Cupric Citrate serves as a light stabilizer in cosmetic formulations. This means it helps to protect the product from the degrading effects of light exposure. When cosmetic products are exposed to light, especially UV light, their ingredients can break down, leading to reduced efficacy and a shorter shelf life. By incorporating Disodium Cupric Citrate, manufacturers can ensure that their products remain stable and effective for a longer period, even when exposed to light.
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).
Disodium Cupric Citrate is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Disodium Cupric Citrate 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.
Side effects and adverse reactions from Disodium Cupric Citrate are relatively uncommon. However, it is always recommended to conduct a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Disodium Cupric Citrate scores a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low score indicates that it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
