The numbers in Lavender 40/42 indicate the linalyl acetate content; in this case, they indicate the product contains 40-42% of linalyl acetate. Lavender 40/42 is generally a blend of various lavenders in order to get a consistent scent from batch to batch, with processors adding linalyl acetate to cover the smell of camphor or borneol components of a given lavender. Since pure essential oils (not diluted, adulterated or tampered with to make them smell better) are ""from the plant"" each lot may vary slightly (sometimes noticeably) due to the climate conditions that year, altitude of the region they're grown in, time of day harvested, etc. Most soapers seem to prefer the Lavender 40/42 because it smells the way they believe lavender should smell and it's fairly inexpensive......about half the price of other, more expensive lavenders.
