Comparison of The Historical Formulas
- The information in the table below needs to be verified. The dates in particular need documented support. Also, the information may need to be expanded as there are at least four different ingredient listings known to exist for Pears soap in recent years.
An analysis of the current ingredients list indeed reveals items such as limonene, whose variant called limonene is characterised by a "turpentine-like odour" also typical of frankincense. Ironically, it is an insecticide as well. However, this item was already present in the pre-2009 formula, so the perceived change might be explained not only by different ingredients but also by different proportions of ingredients.
The latest 2009 modification mainly breaks down to an addition of artificial colouring and substances whose hypothetical function is either as detergents (i.e. cleaning substances) or stabilisers (i.e. product longevity enhancers). However, even the pre-2009 formula was a far cry from the original one. The latter was completely free of industrial cleaners, free of synthetic colours and (apparently) free of synthetic odorants, whose place was occupied by natural herbal fragrances. However, one unknown in the original formula is the "Pears fragrance essence": because of it, the customer cannot be certain whether the "new" fragrant compounds are indeed all new—or simply formerly unlisted items.
During production at Port Sunlight the glycerol (glycerine) content was a result of not removing that formed during the manufacturing process.

Famous quotes containing the words comparison, historical and/or formulas:
“From top to bottom of the ladder, greed is aroused without knowing where to find ultimate foothold. Nothing can calm it, since its goal is far beyond all it can attain. Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned.”
—Emile Durkheim (1858–1917)
“It is hard to believe that England is so near as from your letters it appears; and that this identical piece of paper has lately come all the way from there hither, begrimed with the English dust which made you hesitate to use it; from England, which is only historical fairyland to me, to America, which I have put my spade into, and about which there is no doubt.”
—Henry David Thoreau (1817–1862)
“It is sentimentalism to assume that the teaching of life can always be fitted to the child’s interests, just as it is empty formalism to force the child to parrot the formulas of adult society. Interests can be created and stimulated.”
—Jerome S. Bruner (20th century)
