Quaternium-79 Hydrolyzed Silk, also known as hydrolyzed silk protein quaternary ammonium salt, is a unique ingredient derived from silk proteins. This ingredient is a complex compound, consisting of protein hydrolyzates from silk that have been chemically modified with quaternary ammonium compounds. Specifically, it includes derivatives of 2-hydroxy-3-((3-aminopropyl)dimethylammonio)propyl, combined with N-(1-oxohexadecyl, 1-oxo-9-(Z)-hexadecenyl, and 1-oxo-9-(Z)-octadecenyl) derivatives, and is typically found in the form of chlorides.
The use of silk in beauty and personal care products has a rich history, dating back centuries to ancient civilizations that prized silk for its luxurious texture and beneficial properties. However, the modern incarnation of Quaternium-79 Hydrolyzed Silk emerged with advancements in cosmetic chemistry. Scientists discovered that by hydrolyzing silk proteins and then modifying them with quaternary ammonium compounds, they could create a more versatile and effective ingredient for hair and skin care.
The production process of Quaternium-79 Hydrolyzed Silk involves breaking down silk proteins into smaller peptides through hydrolysis. This makes the proteins more soluble and easier to incorporate into cosmetic formulations. Following hydrolysis, the silk peptides undergo a chemical reaction with quaternary ammonium compounds, which imparts antistatic and conditioning properties. The final product is a multifunctional ingredient that enhances the texture and manageability of hair and skin, making it a popular choice in a variety of beauty products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-79 Hydrolyzed Silk:
One of the primary benefits of Quaternium-79 Hydrolyzed Silk is its antistatic properties. This means it helps to reduce static electricity in your hair. If you’ve ever experienced flyaway hairs or frizz, especially in dry or cold weather, you know how annoying static can be. By incorporating this ingredient into hair care products, manufacturers aim to keep your hair smooth and manageable, reducing those pesky flyaways and giving you a sleeker look.
Quaternium-79 Hydrolyzed Silk is also recognized for its hair conditioning capabilities. This means it helps to improve the texture and appearance of your hair. When used in shampoos, conditioners, or hair masks, it can make your hair feel softer, look shinier, and be easier to comb through. Essentially, it helps to nourish and hydrate your hair, making it look healthier and more vibrant.
In addition to its benefits for hair, Quaternium-79 Hydrolyzed Silk is also used for skin conditioning. This means it helps to improve the feel and appearance of your skin. When included in skincare products like lotions, creams, or serums, it can make your skin feel smoother and more hydrated. It works by forming a protective barrier on the skin’s surface, which helps to lock in moisture and keep your skin feeling soft and supple.
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).
Quaternium-79 Hydrolyzed Silk is generally considered safe for use in cosmetic products, but as with any ingredient, it may not be suitable for everyone. Here are some potential side effects of its topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-79 Hydrolyzed Silk during pregnancy are lacking. Therefore, it is advisable to consult a healthcare professional for further advice.
Adverse reactions to Quaternium-79 Hydrolyzed Silk are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Quaternium-79 Hydrolyzed Silk is rated as a 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This means it has a low likelihood of clogging pores, making it generally suitable for people prone to acne, blemishes, or breakouts.
