What Is It?
Cyamopsis Tetragonoloba (Guar) Gum (also called Guar Gum) is a resinous material made from the guar bean. Guar Gum is a type of polysaccharide called galactomannan made from legume plants that consists of a polymannose backbone to which galactose groups are bound. Derivatives of Guar Gum that also may be used in cosmetics and personal care products include Hydroxypropyl Guar, Guar Hydroxpropyltrimonium Chloride and Hydroxypropyl Guar Hydroxypropyltrimonium Chloride. Among these guar ingredients, Guar Hydroxypropyltrimonium Chloride is most frequently used in cosmetic products. It may be used in bath products, hair conditioners, hair dyes, other hair care products and skin care products. Guar Gum and the other guar derivatives may also be used in bath products, hair care products, shaving preparations and skin care products.
Why is it used in cosmetics and personal care products?
The following functions have been reported for Cyamopsis Tetragonoloba (Guar) Gum and the compounds made from Guar Gum:
- Guar Hydroxypropyltrimonium Chloride, Hydroxypropyl Guar Hydroxypropyltrimonium Chloride Binders
– Cyamopsis Tetragonoloba (Guar) Gum, Hydroxypropyl Guar Emulsion stabilizers
– Cyamopsis Tetragonoloba (Guar) Gum, Hydroxypropyl Guar Film formers
– Hydroxypropyl Guar Hair conditioning agents

- miscellaneous – Guar Hydroxypropyltrimonium Chloride Viscosit increasing agents
- aqueous – Cyamopsis Tetragonoloba (Guar) Gum, Hydroxypropyl Guar, Guar Hydroxypropyltrimonium Chloride
Galactomannan polysaccharides, including Guar Gum, are derived from plants of the bean (also called the Legume family). These plants make galactomannan polysaccharides as a source of energy to support the growth of the embryo within the seed. In addition to being used in cosmetics and personal care products, Guar Gum is commonly used as a thickener in foods such as salad dressings, ice cream and soups. Hydroxypropyl Guar is also used in artificial tear solutions.
The Food and Drug Administration (FDA) includes Guar Gum on its list of substances affirmed as Generally Recognized As Safe (GRAS) as a direct food substance. Hydroxypropyl Guar is on FDA’s list of indirect food additives permitted for use in paper and paperboard in contact with aqueous and fatty foods. The safety of Cyamopsis Tetragonoloba (Guar) Gum, Hydroxypropyl Guar, Guar Hydroxpropyltrimonium Chloride and Hydroxypropyl Guar Hydroxypropyltrimonium Chloride has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that these ingredients were safe as used in cosmetics and personal care products.

CIR Safety Review:
The CIR Expert Panel reviewed data the indicated that little Cyamopsis Tetragonoloba (Guar) Gum is absorbed following oral exposure. Therefore, absorption following dermal exposure would also be limited. The CIR Expert Panel reviewed data that indicated that Guar Gum was not genotoxic or carcinogenic and it was not a developmental toxicant. Guar Gum and its derivatives were also not dermal irritants or sensitizers.
Based on the available data, the CIR Expert Panel concluded that Cyamopsis Tetragonoloba (Guar) Gum, Hydroxypropyl Guar, Guar Hydroxpropyltrimonium Chloride and Hydroxypropyl Guar Hydroxypropyltrimonium Chloride were safe as used in cosmetic and personal care products.

More Scientific Information:
In naming plants, botanists use a Latin name made up of the genus and species of the plant. For example, under this system the plant, guar bean is known as Cyamopsis tetragonoloba (L.) Taub., where (L.) Taub. represents the names of the persons who first described the type of plant specimen. Plants are also known by common names that are handed down through generations. These common names may vary from country to country, for example guar bean is also known as cluster bean and Siam bean. Therefore, Latin names, which are more likely to be recognized in many countries, are frequently used on the label of a product to identify an ingredient made from plants.
