Shower baths with peeling properties, a new market trend, can also be formulated with alkyl polglycosides. Soft abrasive particles, such as hardened jojoba wax, walnut bark, cellulose granules, apricot kernels, etc., are incorporated to re-... 

A considerable quantity of oil can be extracted from waste material from shelling and processing plants, eg, the inedible kernels rejected during shelling and fragments of kernels recovered from shells. About 300 t of pecan oil and 300—600 t of English walnut oil are produced aimuaHy from such sources. The oil is refined and used for edible purposes or for the production of soap the cake is used in animal feeds (see Feeds and feed additives). Fmit-pit oils, which closely resemble and are often substituted for almond oil, are produced on a large scale for cosmetic and pharmaceutical purposes (143). For instance, leaves, bark, and pericarp of walnut may be used to manufacture vitamin C, medicines, dyes and tannin materials (144). 

The toxic influence exerted by Juglans nigra (black walnut) on other plants has been attributed to 5-hydroxy-1,4-naphthoquinone (juglone) (11,31). Hydrojuglone is present in the root bark, leaves, and fruit husks. This compound is not considered toxic, but it is oxidized to the toxic juglone upon exposure to air (51). Rainfall... 

The second report on MDF in 1976 came from Chow at the University of Illinois (62). He, too, worked with hardwood barks including cottonwood, red oak, white oak, and walnut. Furnish was prepared in pressurized refiners and by hammermilling. Urea formaldehyde resin percentages were 5.0, 7.5, and 10.0%, plus 1% wax. He concluded that the fiber from the pressurized refiners was superior to hammermilled particles. Cottonwood and white oak furnish gave better boards, exceeding or approaching requirements of present standards for type 1-B-l commercial particleboard. 

Like H. globosa the Jamaica walnut or blackwood or bitter plum (P. baccatum) contains sesquiterpenes as well as norditerpenes of the picrotoxane type. Picro-dendrin Q (74), the most toxic picrotoxane for mammals, is found in the bark of this tree. In the Dominican Republic, the tree is also called mata becerro (calf killer) and its bark is used to kill lice and bed bugs (239). 

Juglone (5-hydroxy-1,4-naphthoquinone) is a water-soluble yellow pigment that is exuded from leaves, fruits, bark, and roots of black walnut Juglans nigra), English walnut (J. regia), and hickory (Carya ovata) trees, among others. 

Tree stunted and bears yellow leaves. Causes Crown rot blackline. If the trunk near the soil line is diseolored or oozing sap. suspect crown rot, a disease caused by too much water and poor soil drainage. Improved drainage may help. If you find small holes or cracks at the graft union, remove some bark around the area and look for a black line. Blackline virus infects English walnuts grafted onto J. hindsii rootstocks. There is no cure. 

Gallic acid (also called 3,4,5-trihydroxybenzoic acid) (Figure 2.17) is a natural plant phenol. It is an organic acid found in walnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. Gallic acid has been found to... 

Wood wastes do sometimes contain substances that are toxic to plants. In the studies with the 28 species of trees, Allison (1965) reported that most of the woods and barks were not toxic, but California incense cedar and white pine bark were very toxic to garden peas even at the rates of 1 and 2% added to soil in the presence of adequate nitrogen and lime. The woods of red cedar, Ponderosa pine, and loblolly pine, and the barks of California incense cedar and yellow poplar were slightly toxic at the 2-4% rates. The toxicity symptoms usually decreased with time during the two- to three-month period following addition to the soil. There have also been reports that a few other woods, such as walnut, hemlock, fir, and balsam are sometimes, but not always, toxic. Toxicity seems to vary with the age of the tree, and is also dependent upon the quantity added and the test plant. Decomposition time curves, reported by Allison, indicate that it is not uncommon for wood products to slightly retard early decomposition, apparently until the toxic materials disappear. The chemical nature of any toxic products present is not known with certainty but some investigators have attributed the toxicity to resins, turpentine and tannins. 

Bark fibers, which would be expected to have a non-polar (ligninlike) surface gave good results when used as a filler in nonpolar thermoplastics. Likewise, peanut hull flour and walnut shell flour, which are rich in phenolic, lignin-like material, are relatively good fillers. Treatment of the surface of rice hull flour to increase its compatability with thermoplastic resins has been shown to greatly enhance its value as a filler. None of the shell flours are fibrous. 

A group of natural and synthetic dyestuffs based on the naphthoquinone structure (phenolic) have found use in the formation of lake and other pigments. Naphthoquinones are found in the leaves, blossoms, wood, bark, roots and fruit of about 20 different species. Those which are found in pigment use are AUcannin and Alkannan in AUcanet from plant species such as Alkanna lehmannii Tineo (formerly known as Alkanna tinctoria Tausch.), Macrotomia spp., Onosma spp. and juglone in Walnut qq.v.) fiom Juglans spp. 

Thompson (1935) has noted the use of apple tree bark to produce a yellow described in two fifteenth century German texts Mains species (Rosaceae) are known to contain quercetin in their bark, especially that covering the roots and quercetin is a minor component of Vaccinium myrtillns L. and walnut dyes from species such as Juglans nigra L.
