HallStar® EGDS

INCI Name: Glycol Distearate
Product Code: H009
CAS #: 627-83-8
EINECS: 211-014-3
Brand: HallStar®

HallStar® EGDS is the product of the reaction of stearic acid with ethylene glycol. It is a mixture of mono- and di- esters, as reflected in its saponification value. Its effectiveness as an opacifier and pearlizing agent is due to its near insolubility in aqueous systems.

Utilized at a level of 1% to 2% in cream and lotion (O/W emulsion) products, HallStar® EGDS 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 HallStar® EGDS 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).
