Quaternium-90, also known as Di(palm-oil-alkyl)dimethylammonium chloride, is a synthetic compound primarily used in cosmetic products for its antistatic properties. This ingredient is derived from palm oil, which is a common source of fatty acids used in various personal care formulations. Chemically, it belongs to the quaternary ammonium compounds, a group known for their conditioning and antistatic abilities.
The history of Quaternium-90 in cosmetics dates back to the mid-20th century when the demand for more effective hair and skin care products led to the exploration of new synthetic ingredients. Quaternary ammonium compounds were found to be particularly effective in reducing static electricity and improving the texture of hair and skin, making them popular choices for conditioners, shampoos, and lotions.
The production of Quaternium-90 involves a chemical reaction between palm oil-derived fatty acids and dimethylamine, followed by a quaternization process using methyl chloride. This results in a stable compound that can be easily incorporated into various cosmetic formulations. Despite its synthetic nature, the use of palm oil as a starting material provides a link to natural sources, which can be appealing to consumers looking for effective yet naturally-derived ingredients.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-90:
One of the primary benefits of Quaternium-90 is its antistatic properties. This means that it helps to reduce or eliminate static electricity, which can be a common issue in hair care products. When you use a product containing Quaternium-90, it helps to prevent your hair from becoming frizzy or flyaway due to static. This can be particularly beneficial in dry climates or during the winter months when static electricity tends to be more prevalent.
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-90, or Di(palm-oil-alkyl)dimethylammonium chloride, is generally considered safe for use in cosmetic products. However, like any ingredient, it can cause side effects in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-90 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.
Adverse reactions to Quaternium-90 are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to conduct a patch test before widespread usage.
Quaternium-90 has a comedogenic rating of 1, which means it is unlikely to clog pores and cause acne or breakouts. This makes it a suitable option for individuals prone to acne or blemishes.
