Zinc Bis-(Methyl Palmitoyl Aspartate), also known as di-(N-hexadecanoyl L-aspartate 4 methyl ester) of zinc, is a synthetic compound used in the cosmetic industry primarily for its skin-protecting properties. This ingredient is a zinc salt of a fatty acid derivative, combining zinc with methyl palmitoyl aspartate. The chemical composition involves zinc ions complexed with two molecules of N-hexadecanoyl L-aspartate, which is a derivative of aspartic acid esterified with palmitic acid.
The use of zinc in skincare isn’t new; zinc compounds have been utilized for their protective and soothing properties for centuries. However, Zinc Bis-(Methyl Palmitoyl Aspartate) is a more recent innovation, designed to enhance the skin-protecting benefits of traditional zinc compounds while improving their compatibility and efficacy in modern cosmetic formulations.
The production of Zinc Bis-(Methyl Palmitoyl Aspartate) involves a multi-step chemical synthesis. Initially, palmitic acid is esterified with aspartic acid to form N-hexadecanoyl L-aspartate. This intermediate is then methylated to produce the methyl ester form. Finally, the methyl palmitoyl aspartate is reacted with a zinc salt to form the final zinc complex. This process ensures that the resulting compound is stable, effective, and suitable for use in various skincare products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Zinc Bis-(Methyl Palmitoyl Aspartate):
Zinc Bis-(Methyl Palmitoyl Aspartate) is primarily known for its skin-protecting properties. This means that it helps to shield the skin from various environmental stressors, such as pollution, UV rays, and harsh weather conditions. By forming a protective barrier on the skin’s surface, it helps to prevent damage and maintain the skin’s overall health. This can be particularly beneficial for individuals with sensitive or easily irritated skin, as it provides an extra layer of defense against potential irritants.
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).
Zinc Bis-(Methyl Palmitoyl Aspartate) 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 Zinc Bis-(Methyl Palmitoyl Aspartate) during pregnancy and breastfeeding are lacking. Therefore, it is recommended to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Zinc Bis-(Methyl Palmitoyl Aspartate) are relatively uncommon. However, as with any new skincare product, it is advisable to conduct a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, Zinc Bis-(Methyl Palmitoyl Aspartate) 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 suitable for individuals prone to acne, blemishes, or breakouts.
