Functional Carbohydrates
Carbohydrates such as glucose, fructose and maltose are used to adjust the osmotic pressure of the formulation. Starches and cellulose are used to increase the viscosity of water. Hydroxyethyl cellulose is one of the most commonly used water thickeners in cosmetics. Alfa Chemistry can supply high-quality functional carbohydrates to cosmetic companies looking to create innovative skincare products.

Carbohydrates are a series of biological molecules with multiple C-OH bonds and a ketone/aldehyde group, and it can be categorized into simple and complex carbohydrates. Simple carbohydrates have one or two sugars. Complex carbohydrates contain three or more sugars. Carbohydrates have excellent moisturizing and dampening properties. They are more effective when used in cleansers and various types of creams. Adding a certain amount of carbohydrates to cosmetics not only prevents the disappearance of water from the cosmetics, but also hydrates the water on the stratum corneum. Cosmetics containing carbohydrates are also easily absorbed by the skin.
Examples of Carbohydrates in Cosmetics
- Acacia Senegal Gum
Acacia Senegal Gum can be used in various capacities to enhance the smooth feel or adhesion of a skin care formula; it also functions as a thickening agent, emulsifier, or stabilizer. - Galactoarabinan
Galactoarabinan can prevent natural water evaporation, provide long-lasting moisture, improve skin's appearance and texture, smooth and treat wrinkles, strengthen the skin's natural barrier, and increase the effectiveness of sunscreens. - Dextran
In cosmetic formulations, dextran can act as a binder to improve the dispersion of ingredients in cosmetic formulations. It also can be used as a thickener to help maintain the proper consistency. - Dextrin
Dextrin is a gum produced by the incomplete hydrolysis of starch, which is a minor auxiliary ingredient that can be used as a thickener, humectant, foam booster, adhesion promoter and filler. - Cellulose Gum
Cellulose Gum has excellent water-binding properties that help improve hydration and moisture retention in skin care and hair care products. It can also be used as a thickener to bind other ingredients together. - Glucomannan
Glucomannan is a polysaccharide polymer which can form a film on the skin and reduce transdermal water loss. It also improves product stability and shelf life.
