Embodiment 5 and 6 and comparative Embodiment 7

[0077] The remaining cross-linked products of the present invention are shown in Table 2, Examples 5 and 6. Example 5 was prepared according to the method of Example 3 to obtain cationic guar gum with a cationic DS of 0.14. The product of Example 6 was prepared according to the method of Example 3, but with 30% more 2-hydroxypropyl-3-trimethylammonium chloride to achieve a cationic DS of 0.2. The 1% aqueous viscosity of the products in Examples 5 and 6 of the present invention is similar to that of the borate-crosslinked cationic guar gum in Comparative Example 7.

Embodiment 8 and 9 and comparative Embodiment 10-11

[0079] Conditioning properties of the products of the invention

[0080] The cationic polygalactomannan materials of Examples 5 and 6 of the present invention were used in conditioning shampoo formulations, which are shown in Examples 8 and 9 of Table 2, and compared with those containing Comparative Example 7. A shampoo with borate crosslinked cationic guar (Example 10) was compared with a shampoo without cationic guar (Example 11).

[0081] Shampoo preparation

[0082]77 parts by weight (pbw) of the surfactant premix composition shown in Table 3 was mixed with 19 pbw deionized water and 0.3 pbw polymer of the present invention using a Caframo overhead mechanical stirrer with dispersing paddles at 600 rpm, and The conditioning shampoo formulations in Table 2 were prepared by allowing the compositions to mix for 45 minutes at ambient temperature. At this point, 3 pbw of silicone emulsion (Dow Corning 1784) was added to the formulation and mixing was continued for 15 minutes....

Embodiment 12-13 and comparative Embodiment 14

[0097] Application in skin care, body wash

[0098] The thickening performance of the product of the present invention in body wash formulations is shown in Table 4. A body wash formulation was prepared by adding 0.3 pbw of the inventive polymers of Examples 5 and 6, and water (to bring the volume to 100) to 76 pbw of the body wash premix formulation in Table 5. Mix for 1 hour using an overhead mechanical stirrer with dispersing paddles. The pH of the body wash is 5.6.

[0099] The body washes of Examples 12 and 13 contained the polymers of Examples 5 and 6 of the present invention, respectively. Addition of the polymers of the present invention to the body wash formulation resulted in an increase in the viscosity of the body wash compared to the control body wash of Example 14 which did not contain cationic guar gum.

Abstract

The present invention relates to polygalactomannan compositions, and more particularly cationic guar gum compositions, which, when crosslinked with glyoxal, from discrete guar particles which are capable of being easily dispersed in water which permits subsequent processing of the guar, such as washing. The guar and its derivatives are desirable for use in applications such as personal care, household care products and the like.

Description

[0001] related application [0002] This application claims priority to US Provisional Application Serial No. 60 / 856,486, filed November 3, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to polygalactomannan compositions, and more particularly to guar gum compositions, which, when cross-linked with glyoxal, form individual guar gum particles that are readily dispersible in water , so that subsequent processing of the guar gum, such as washing, is possible. It is desirable to use guar gum and its derivatives in applications such as personal care or household care. Background technique [0004] Polygalactomannans and their derivatives are used in various applications such as oil recovery, personal care, textiles, paper, coatings, food, and more. Polygalactomannan and its derivatives are difficult to disperse in aqueous solutions because they tend to form sticky particles that form agglomerates or agglo...
