What is Xylitol?
Xylitol is a natural sweetener that is derived from various fruits and vegetables, most notably birch trees and corn cobs. It is also known by other names such as Birch Sugar, E967, and Xylit. Chemically, it is classified as a sugar alcohol, or polyalcohol, with the molecular formula C5H12O5. It is a white crystalline substance that is soluble in water.
The use of Xylitol in cosmetic products dates back to the 1960s. It was initially used in the food industry as a sugar substitute due to its low glycemic index and dental benefits. However, researchers soon discovered its potential in the cosmetic industry due to its unique properties. Xylitol is produced through a process known as hydrogenation, where xylose, a simple sugar derived from plant materials, is converted into xylitol.
Compared to other similar ingredients, Xylitol stands out due to its multi-functional properties. While other sugar alcohols like glycerin and sorbitol are primarily used as humectants, Xylitol also functions as an anti-seborrheic and deodorant. This makes it a versatile ingredient in cosmetic formulations.
What makes Xylitol unique is its ability to inhibit the growth of certain bacteria, which can be beneficial in products designed for acne-prone skin. It also has a cooling effect when applied to the skin, which can be soothing in products designed for irritated or inflamed skin.
Xylitol is typically used in a wide range of cosmetic products. Due to its humectant properties, it is commonly found in moisturizers and serums, where it helps to retain moisture in the skin. It is also used in deodorants due to its ability to inhibit bacterial growth and reduce body odor. Additionally, its sweet taste makes it a popular ingredient in lip balms and other lip care products.
Benefits and Uses
In this section, we will delve into the officially recognized benefits and uses of Xylitol:
Anti-Seborrheic
Xylitol is known for its anti-seborrheic properties. In simpler terms, it helps in controlling the production of sebum, the oily substance produced by our skin. Excessive sebum can lead to problems like acne and oily skin. By regulating sebum production, Xylitol helps in maintaining a balanced and healthy skin condition.
Deodorant
Another official function of Xylitol is its use as a deodorant. It has the ability to neutralize body odors, providing a fresh and clean feeling. This makes it a common ingredient in many cosmetic products like deodorants and body sprays.
Flavouring
Xylitol is also used as a flavouring agent in cosmetic products. It is often found in oral care products like toothpaste and mouthwash due to its sweet taste and ability to fight cavities. It enhances the overall user experience by adding a pleasant taste to the product.
Humectant
As a humectant, Xylitol helps in retaining moisture in the skin. It attracts water molecules and locks them into the skin, preventing dryness and keeping the skin hydrated and supple. This property makes Xylitol a popular ingredient in moisturizers, lotions, and other skin care products.
Please note that these benefits are based on the officially recognized and defined functions of Xylitol. There may be other benefits and uses of this ingredient that go beyond the scope of these official functions.
Safety Profile
Xylitol is not a banned or regulated ingredient in cosmetics. It is generally considered safe for use in cosmetic products. However, like any ingredient, it may not be suitable for everyone and can potentially cause allergic reactions in some individuals.
Some potential side effects of topical application of Xylitol include:

A note for women who are pregnant and/or breastfeeding – there is currently insufficient data on the safety of topical usage of Xylitol during pregnancy or breastfeeding. Therefore, it is recommended to consult a healthcare professional for further advice.
