Maltitol, scientifically known as 4-O-α-D-Glucopyranosyl-D-glucitol, is a sugar alcohol derived from maltose, a disaccharide found in starches. In the context of cosmetics, maltitol is celebrated for its multifunctional properties, including its roles as a fragrance, humectant, moisturizing agent, and skin conditioning ingredient. Its chemical composition allows it to attract and retain moisture, making it a valuable addition to various skincare and beauty products.
The history of maltitol’s use in cosmetics is relatively recent compared to its application in the food industry, where it has been used as a sugar substitute for decades. Initially, maltitol was primarily utilized in the production of sugar-free and low-calorie foods due to its sweetening properties and lower caloric content. However, as the cosmetic industry began to explore the benefits of sugar alcohols, maltitol’s potential as a hydrating and skin-conditioning agent was recognized.
Maltitol is produced through the hydrogenation of maltose, which is derived from the enzymatic breakdown of starches such as corn or wheat. This process involves converting the aldehyde group of maltose into a primary alcohol group, resulting in the formation of maltitol. The end product is a white, crystalline powder or a clear, viscous liquid, depending on the specific formulation and intended use in cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Maltitol:
Maltitol is used as a fragrance ingredient in cosmetics. This means it can contribute to the overall scent profile of a product, making it more pleasant to use. Whether it’s a subtle hint or a more pronounced aroma, Maltitol helps enhance the sensory experience of your skincare or beauty routine.
As a humectant, Maltitol has the ability to attract and retain moisture. This is particularly beneficial for keeping your skin hydrated. By drawing moisture from the environment into the skin, it helps maintain a healthy and plump appearance, reducing the likelihood of dryness and flakiness.
Maltitol also functions as a moisturizing agent. This means it not only attracts moisture but also helps to lock it in, providing a longer-lasting hydration effect. This can be especially useful in products designed for dry or dehydrated skin, ensuring that your skin stays soft and supple throughout the day.
Lastly, Maltitol serves as a skin conditioning agent. This means it helps to improve the overall feel and appearance of the skin. By enhancing the skin’s texture and smoothness, it can make your skin look healthier and more radiant. This function is particularly valuable in a wide range of skincare products, from lotions to serums.
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).
Maltitol is generally considered safe for topical use in cosmetics, with a low potential for causing allergic reactions. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of maltitol during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to maltitol are relatively uncommon, but it is always prudent to perform a patch test before widespread usage to ensure personal tolerance.
Maltitol has a comedogenic rating of 0, meaning it is considered non-comedogenic. This is beneficial for individuals prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
