Arcadi boix camps writes about helional first in 1978: “a product with a fresh melon fruity odor, it is endowed with a great fixing power. it is a product that has decisive influence in perfumes such as diorella and dior dior where, together with hedione and other compounds the perfumer happily obtains an exceptional naturalness. its blends with cis-jasmone, dihydrojasmone and the alcohols c-9, c-10 and c-11 are very important. it is another product that is strongly influencing the evolution of perfumery in the present day” in 1985 he adds “i wish to insist that helional and calone, already described, are products of infinite quality, whose creative possibility are likewise infinite.”
