The Science Behind Sorbitol: How It Works as a Humectant and Sugar Alcohol
Sorbitol is a type of sugar alcohol that is commonly used in various industries, including food, pharmaceuticals, and personal care products. It is known for its humectant properties, which help attract and retain moisture, making it a popular ingredient in products like skin creams, toothpaste, and sugar-free candies. In this report, we will delve into the science behind sorbitol, its functions as a humectant and sugar alcohol, and its applications in different industries.
What is Sorbitol?
Sorbitol is a sugar alcohol that occurs naturally in fruits like apples, pears, peaches, and prunes. It is also produced synthetically from glucose through a process called hydrogenation. Sorbitol is a white, crystalline powder with a sweet taste and is commonly used as a sugar substitute in sugar-free and low-calorie products.
Sorbitol is classified as a humectant, which means it has the ability to attract and retain moisture. This property makes sorbitol a valuable ingredient in skincare products, as it helps hydrate the skin and prevent dryness. In addition to its humectant properties, sorbitol is also used as a sugar alcohol in food products to provide sweetness without the calories of sugar.
How Does Sorbitol Work as a Humectant?
As a humectant, sorbitol works by drawing moisture from the air into the skin, helping to keep it hydrated and supple. When sorbitol is applied to the skin, it forms a thin film that helps to lock in moisture and prevent water loss. This makes sorbitol an effective ingredient in moisturizers, lotions, and other skincare products designed to hydrate and nourish the skin.
In addition to its humectant properties, sorbitol also has emollient properties, which help to soften and smooth the skin. This makes sorbitol a versatile ingredient in skincare formulations, as it can help improve the texture and appearance of the skin while providing hydration.
Applications of Sorbitol in Different Industries
Sorbitol is widely used in the food industry as a sugar substitute in sugar-free and low-calorie products. It is commonly found in sugar-free candies, chewing gum, and baked goods, where it provides sweetness without the calories of sugar. Sorbitol is also used as a bulking agent in diet foods and beverages, helping to add volume and texture without the added calories.
In the pharmaceutical industry, sorbitol is used as an excipient in oral medications and syrups. It is also used in liquid formulations to improve the taste and palatability of medications. Sorbitol is known for its sweet taste and is often used to mask the bitter flavors of certain drugs, making them more pleasant to take.
In the personal care industry, sorbitol is a common ingredient in skincare products like moisturizers, lotions, and creams. Its humectant properties help to hydrate and nourish the skin, making it an effective ingredient in products designed to treat dryness and improve skin texture. Sorbitol is also used in toothpaste and oral care products to help maintain moisture in the mouth and prevent dryness.
