Quaternium-98, also known as Lauryl Propylenediamine Ethoxylate Laurate or simply Quaternium-98, is a complex quaternary ammonium salt. This ingredient is created through a multi-step chemical process that involves reacting a 23 mol ethoxylate of lauryl propylenediamine with lauric acid, followed by quaternization with dimethyl sulfate. The result is a compound that serves multiple functions in cosmetic formulations, primarily as a hair conditioning agent, skin conditioning agent, and emollient.
The history of Quaternium-98 in cosmetics is relatively modern, as the demand for multifunctional and effective conditioning agents has grown. Initially, simpler quaternary ammonium compounds were used, but advancements in chemistry allowed for the development of more complex and effective ingredients like Quaternium-98. Its ability to provide superior conditioning and emollient properties has made it a popular choice in a variety of hair and skin care products.
Quaternium-98 is prized for its ability to improve the texture and manageability of hair, making it smoother and easier to comb. It also offers skin conditioning benefits, helping to maintain the skin’s moisture balance and leaving it feeling soft and supple. Despite its many benefits, it’s important to understand what Quaternium-98 can and cannot do, so consumers can make informed decisions and not be misled by marketing claims.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-98:
Quaternium-98 is a fantastic hair conditioning agent. This means it helps to improve the texture and appearance of your hair, making it feel softer, smoother, and more manageable. If you’ve ever struggled with frizzy or tangled hair, products containing Quaternium-98 can be a game-changer. It works by forming a thin, protective layer on the hair shaft, which helps to lock in moisture and reduce static electricity. This results in hair that looks shinier and feels silkier to the touch.
When it comes to skin conditioning, Quaternium-98 excels at making your skin feel more supple and hydrated. It acts as a humectant, which means it helps to attract and retain moisture in the skin. This can be particularly beneficial for those with dry or dehydrated skin, as it helps to maintain a healthy moisture balance. By keeping your skin well-hydrated, Quaternium-98 can also help to improve its overall texture and appearance, making it look more radiant and youthful.
As an emollient, Quaternium-98 helps to soften and smooth the skin. Emollients are crucial in skincare because they fill in the tiny gaps between skin cells, creating a smoother surface. This can be especially beneficial for people with rough or flaky skin, as it helps to create a more even and polished look. Additionally, the emollient properties of Quaternium-98 can provide a protective barrier on the skin, helping to shield it from environmental aggressors and prevent moisture loss.
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-98 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.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-98 during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions to Quaternium-98 are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that you do not have an adverse reaction.
Quaternium-98 has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
