  • Esters
    Patent number: 6974804
    Abstract: Acylated cellobiose compounds (CHME) which satisfy the formula; wherein X represents an acyl group (R—CO—) or H, Z represents an acyl group (R?—CO—) or H and not more than a minority of X+Z residues represent H, R represents a saturated or unsaturated, linear or branched chain hydrocarbon residue of 5 to 31 carbon atoms and R? represents a residue, different from R, which is: (i) a saturated or unsaturated, linear or branched chain hydrocarbon residue of 1 to 31 carbon atoms, or (ii) an aromatic hydrocarbon residue, or (iii) a cycloaliphatic hydrocarbon, each optionally substituted. CHME esters are particularly suited to thickening or structuring a water-immiscible liquid, for example, a phase in a cosmetic formulation, such as antiperspirant or deodorant formulations, eg water in oil emulsions and especially translucent ones.

  • Laundry detergent gel with suspended particles
    Patent number: 6972278
    Abstract: A shear-thinning lamellar gel detergent composition containing suspended particles, employing a non-neutralized fatty acid as a structuring agent, in a specific amount, depending on the total surfactant level. The weight % ratio of non-neutralized fatty acid to the total surfactant within a specific range, defined by the Gelling Index equation, results in gels with the desired properties. The inventive product offers an advantage of laundry pre-treater and a detergent in a single product and also provides a visual cue of suspended particles.

  • Pour spout fitment and container
    Patent number: 6968980
    Abstract: The present invention is directed to a pour spout fitment that has an enlarged spout opening thereby making it less susceptible to double pouring and advantageous for dispensing new flowable product forms such as gels. The pour spout opening is large relative to the bottle opening which is equated with the fitment's circumscribing wall. Accordingly, the pour spout fitment is less susceptible to double pouring and may also be useful for pouring more viscous product forms such as gels.
