NATROSOL HEC

CAS NO:9004-62-0
EC NO:618-387-5

Nature-derived from sustainably sourced cellulose, natrosol hec products are water-soluble, non-ionic polymers that can be used in a variety of personal and home care applications. These efficient thickeners perform across a wide pH range and demonstrate high salt tolerance and broad surfactant compatibility, enabling clear formulations.

Natrosol hec, a nonionic, water-soluble polymer, is a white, free-flowing granular powder. 
Natrosol hec is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified hec for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis).

Natrosol hec is easily dissolved in cold or hot water to give crystal-clear, shear-thinning solutions of varying viscosity. Furthermore, low to medium molecular weight types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containing up to 60 percent ethanol. 
Natrosol hec is generally insoluble in organic solvents.

oral care features and benefits:
offers excellent tolerance to mono-, di-, and tri-valent cations
provides rheology properties such as shear-thinning for ease of filling tubes during manufacture and dispensing onto toothbrush
imparts glossy, smooth ribbon appearance
inhibits syneresis formation
is nonionic resulting in compatibility with wide range of actives

oral care applications:
toothpastes
mouthwashes
mouth moisturizers
mouth sprays and gels

Natrosol hec is a nonionic, water soluble polymer derivatized from natural, renewable resources. 
Natrosol hec is used as a thickener, rheology modifier and syneresis control agent in toothpaste formulations where high di- and trivalent salt tolerance is required. The addition of HEC to toothpaste provides excellent gloss. Additional HEC grades are available.

Key Applications
Hair Care; Oral Care; Skin Care

Product Description
This nonionic, water-soluble polymer is used to create products that are rich and thick from the container, but spread easily on hair and skin. 
Natrosol hec is easily dissolved in cold or hot water to give crystal clear solutions of varying viscosities. Low to medium molecular weight (MW) types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containing up to 60 percent ethanol.

Natrosol hec grades are offered in different viscosity levels (molecular weights), and particle size distributions. 
Natrosol hec grades for paints and coatings applications are typically glyoxylated (R-treated) for ease of incorporation. In latex architectural paints, Natrosol HEC is known for superior color performance, stability, shear-thinning, application properties and sag resistance.

Natrosol hec is a gelling and thickening agent derived from cellulose. 
Natrosol hec is widely used in cosmetics, cleaning solutions, and other household products.
Natrosol hec and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids. This process is known as hydrophilization.

Natrosol hec is also used extensively in the oil & gas industry as a drilling mud additive under the name HEC as well in industrial applications, paint & coatings, ceramics, adhesives, emulsion polymerization, inks, construction, welding rods, pencils and joint fillers.

Natrosol hec can be one of the main ingredients in water-based personal lubricants. 
Natrosol hec is also a key ingredient in the formation of big bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble. 

Natrosol hec is a non-ionic, water soluble polymer used as a thickening agent for aqueous cosmetic and personal care formulations. 
Natrosol hec will produce crystal clear gel products and thicken the aqueous phase of cosmetic emulsions. 
Natrosol hec can be also be used to efficiently thicken shampoos, body washes and shower gels.

Natrosol hec is a polysaccharide derivative with gel thickening, emulsifying, bubble-forming, water-retaining and stabilizing properties. 
Natrosol hec is used as a key ingredient in many household cleaning products, lubricants and cosmetics due to its non-ionic and water-soluble nature. 
Natrosol hec is often used as an ingredient in ophthalmic pharmaceutical preparations such as artificial tear solutions and adjunct agent in topical drug formulations to facilitate the delivery of drugs with hydrophobic character.

Natrosol hec is a polymer obtained by the action of ethylene oxide on cellulose. 
Natrosol hec is used in cosmetics as a thickener.

Natrosol hecs functions (INCI)
Fixing agent: Allows the cohesion of different cosmetic ingredients
Emulsion Stabilizer: Aids the emulsification process and improves emulsion stability and shelf life
Film forming agent: Produces a continuous film on the skin, hair or nails
Stabilizing Agent: Improves ingredients or formulation stability and shelf life
Viscosity control agent: Increases or decreases the viscosity of cosmetics

Natrosol hec is derived from cellulose, a polysaccharide that is the most abundant biopolymer in nature and found in the cell walls of plants as well as in wood and cotton. 
Natrosol hec is used extensively in the personal care industry as a thickening agent. 
Natrosol hec is nonionic (not affected by pH) and soluble in water, thereby providing it with the capacity to thicken the aqueous phase of a formulation. 
Natrosol hec also has reported uses as a binding agent, emulsion stabilizer, and film former.
