It is now fifteen years because the final variation of this reference quantity seemed and through this time new fabrics have seemed and a few have fallen into disuse. the current variation is the results of a lot revision and a few deletion and an attempt has been made to carry the data updated and in conformity with present perform. of modern years numerous speciality fabrics have seemed, and a couple of those are integrated the place their chemical composition is understood. Speciality fabrics of obscure composition will not be integrated. for plenty of of the compounds indexed a number of substitute names are in use, a few of which from the chemist's viewpoint are both insufficient, ambiguous, or sometimes truly deceptive. during this version the compounds were indexed below names that are thought of to be chemically passable and which, whilst, could be quite established to perfumers; they don't inevitably comprise complete details as to the constitution of the com­ pound they usually make unfastened use of broadly authorised trivial names. In lots of the entries this can be through a scientific identify which defines the chemical constitution, whereas synonyms that are in use, notwithstanding occasionally chemically unsatisfactory, are given in brackets, with a cross-reference to the most access. Prefixes denoting structural positive aspects, akin to n-, iso-, cis-, trans-, 0-, m-, p-, etc are left out within the alphabetical listing.

Example text

Small lots of the finest quality when dried and cleaned have in the past been sold to the East and to perfumers but such lots form only a small fraction of the ambergris which comes on the market. Normally, dealers are offered parcels of mixed qualities in a more or less dirty and sometimes wet condition and the estimation of their value is extremely difficult. The purchase of a large lump can fairly be described as a very hazardous speculation. The most valuable part of a large block is the heart or core, and this is invariably surrounded by a stratified crust of very varying thickness.

Bacharach and Lester Smith whose conclusions were that although this oil would be quite valueless as a medicinal or commercial source of Vitamin D, it is perhaps of some scientific interest that it contains a little Vitamin D-this presumably being attributed to solar irradiation of traces of provitamin D. 46 PERFUMES, COSMETICS AND SOAPS Avocado oil can be adopted in any cosmetic formula in which oil is an ingredient. Trial batches should be made, especially if mineral oils have been supplanted by Avocado oil, since the latter, in most cases, will produce a stiffer emulsion.

In appearance it resembles turbid honey, of a yellowish-white colour, and its odour recalls melilot or coumarin; on exposure this alters slightly and approaches that of cedarwood. Balsamo Blanco has been examined analytically with the result that cinnamic acid, cinnamic alcohol, and phenyl propyl alcohol have been identified as constituents. Barberry, or Berberis vulgaris, L.
