GLYCOL DISTEARATE
Synonyms: Ethylene Glycol Distearate, EGDS, Ethylene distearate, Ethylene glycol dioctadecanoate
Glycol Distearate is a solid opacifying and pearlising agent commonly used in haircare products to impart either a white sheen or a pearl effect, depending on the quantity used.
Glycol Distearate, also called Ethylene Glycol Distearate, Ethylene distearate or EGDS, is the diester of stearic acid and ethylene glycol.
Glycol Distearate is most commonly found in personal care products and cosmetics, where it is used to produce pearlescent effects and as a moisturizer.
Glycol Distearate is the product of the reaction of stearic acid with ethylene glycol.
Glycol Distearate is a mixture of mono- and di- -esters, as reflected in its saponification value.
Glycol Distearate is a mixture of monomers and diesters of ethylene glycol and stearic acid, with a high content of diesters.
Glycol Distearate is a pearlising agent, opacifier, and viscosity builder in many personal care products, such as creams, lotions, shampoos, liquid soaps, and bath gels.
Glycol Distearate can also be used as a softening agent in laundry liquid formulations and as a general-purpose emulsifier and emulsions stabilizer in various industrial applications.
Its effectiveness as an opacifier and pearlizing agent is due to its near insolubility in aqueous systems.
Glycol Distearate (Ethylene Glycol Distearate) is often used in products like shampoos, shower gels, cleansers, handwashes and creams.
Glycol Distearate is used as an emulsion stabilizer, a conditioning agent, opacifying agent and a thickening agent.
Glycol Distearate is the ester of ethylene glycol and stearic acid.
Glycol Distearate is said to be naturally derived as stearic acid is obtained from plant or animal sources.
Features & Benefits:
Glycol Distearate has excellent solubility and compatibility with other surfactants, resulting in great formulating flexibility.
Glycol Distearate offers superior opacifying performance and bright white appearance can make the product more substantial and features a soft velvety feel.
Glycol Distearate helps to form a three-dimensional brilliant, uniform and stable, bright satin-like pearlescent texture.
Mild and low irritation makes Glycol Distearate perfect for formulating all kinds of skin-touch products, to name a few, Shampoo, Body Lotion, Facial Cleanser, and Hand Soap Liquid.
Glycol Distearate has outstanding biodegradability(degradation rate up to 97%), and hard water resistant property.

Ethylene Glycol Distearate, or EGDS for short, is the crucial ingredient in pearlescent-looking personal care products and cosmetics.
Glycol Distearate dissolves and emulsifies upon heating(at least 75℃) in the surfactant complex and precipitates out lens-like crystals during cooling, thus producing a pearlescent luster.
It plays a 3-in-1 role in the formula, i.e., Surfactant, Opacifier, and Pearlizing agent.
Glycol Distearate is gentle on the skin with low irritation.
Glycol Distearate features superior opacifying performance and a bright white appearance, making the final product more substantial and demonstrating a soft, velvety feel.
Ethylene Glycol Distearate also can easily dissolve in water and is highly compatible with many other surfactants.
Utilized at a level of 1% to 2% in cream and lotion (O/W emulsion) products, Glycol Distearate (Ethylene Glycol Distearate) will contribute body, opacity and a soft velvety feel.
Higher levels (up to 10%) can impart additional body, bringing the product towards a stiff paste consistency.
When incorporated at 0.5% to 2.5% in aqueous personal care cleansing products, brilliant pearlescence results.
Consistent batch to batch pearlescent effects require formulation and manufacture under carefully controlled conditions.
For optimal effect it is important to heat the batch to at least 75°C and to maintain this temperature until Glycol Distearate is completely melted and finely dispersed.
The batch is then cooled to room temperature (~30°C maximum) with continuous agitation.
If used at too high a level, excessive opacity will diminish the pearlescent effect.
If incorporated at too low a level, solubilization by surfactants can result in either no pearlescence or delayed and excessively temperature-sensitive pearlescence (resulting in product that is, or becomes, hazy or murky).
Glycol Distearate must be melted either before use or during processing, depending on the formulation type.
Upon cooling, Glycol Distearate re-crystalizes to form either a turbid or pearlescent structure.
It may also be dyed or pigmented or coloured with Micas for a sparkle/shimmer effect as well as to give coloured opaque or pearly effects.
The glycol part of this molecule is sourced from ethylene glycol which is commonly petrochemical derived, the distearate is from stearic acid which is usually from vegetable sources.
However as plant-based glycols become available at better prices, this product may become 100% plant based.
Glycol Distearate is oil Soluble but it is also surface active so can be melted into an aqueous product, especially in the case of shampoos and bodywashes. Glycol Distearate has an HLB of around 5-6 and can be used as a co-emulsifer for water in oil (w/o) emulsions.
The melting Point is 58-64 C and typical usage is between 2 -4% (with a maximum 10%) depending on the desired effect.
Diester of stearic acid and ethylene glycol.
It is a pearlized agent for cleaning formulations such as shampoo and facial wash foam.
It gives a relatively large crystalline pearl sheen.
It is relatively stable even when formulated in low-viscosity formulations.
Glycol Stearate, Glycol Stearate SE (Self Emulsified), and Glycol Distearate are white to cream-colored waxy solids.
All three ingredients are mixtures of mono- and diesters of ethylene glycol and stearic acid.
Glycol Stearate is predominantly the monoester, while Glycol Distearate is predominantly the diester.
Glycol Stearate SE is a self-emulsifying grade of Glycol Stearate that contains some sodium and/or potassium stearate.
Glycol Stearate, Glycol Stearate SE, and Glycol Distearate may be used to formulate a wide variety of cosmetics and personal care products, including bubble baths, makeup, hair, skin, and nail care products.
