Abstract
The invention is directed to a pliable play gel composition comprised of certain guar gums, a cross-linking agent, and water in certain amounts to form a composition having exceptional gel cohesiveness and rheology resulting in a free flowing play gel exhibiting a novel texture and tactile feel character. The nature of the instant play gel enables the use of the guar based gel in a host of play patterns for children or adults which exploit its free flowing and pleasantly comfortable tactile feel characteristics.
Claims17
A pliable play gel comprising a malleable amorphous binder selected from the group of guar gums consisting essentially of hydroxypropyl guar (HPG), carboxymethyl guar (CMG) and carboxymethyl hydroxypropyl guar (Carboxymethyl 2-Hydroxypropyl Ether) (CMHPG) present in an amount of from about 0.5 to 2.0 percent by weight, a guar gum crosslinking agent, and water said gel being characterized by a flow rheology and a pleasurable tactile feel texture.
A pliable play gel comprising the following materials expressed as percent by weight of the total composition:
- Ingredient Percent by Weight Water 90.00-98.00 Cross-Linking Agent 0.10-1.00 Colorant 0.0005-1.00 Preservative (minerai oil) 0.10-1.00 Carboxymethyl hydroxypropyl guar 0.5-2.00 Fragrance As needed Plasticizer/Humectant As needed.
A process for preparing a pliable, cohesive, free flowing gel comprising:
- a) mixing a guar gum polymer selected from the group of guar gums comprising hydroxypropyl guar (HPG), carboxymethyl guar (CMG) and carboxymethyl hydroxypropyl guar (Carboxymethyl 2-Hydroxypropyl Ether) (CMHPG) in amounts of from about 0.5 wt. % to 2.0 wt. % of the total anticipated composition of the free flowing gel and water at an elevated temperature, to form a solution;
- b) adding a cross-linking agent to the solution in amounts of from about 0.1 wt. % to 1.0 wt. % of the total anticipated composition of the free flowing gel to form a gel suspension;
- and
- c) mixing the entire suspension to attain viscosities of from about 750 to 1200 centipoints thereby resulting in the formation of a uniform, viscous gel of high flow rheology.
