to thirteen weeks so that the alcohol used in the process could evaporate and be re-used. The soap bars were laid out on wooden trays in drying rooms known as "ovens" about the size of a domestic garage. Bars were placed on trays with both sides open to the air. Ovens were graded in warmth from around 70F (21C) to 100F (39C). As drying proceeded trolleys loaded with trays were moved to progressively warmer ovens. In practice the soap often became opaque. Unilever explored options to prevent this, all of which would have added to the cost: rotating the trays periodically so that those at the top were moved to the bottom; adding large paddle wheels to circulate the air better; completely re-duct the way in which the warm air entered the ovens to achieve the same effect. 2003 change On 27 February 2003 the 7th Amendment to the EU Cosmetics Directive (Directive 2003/15/EC) introduced a new legal requirement related to the labelling of 26 specific ingredients if present in a cosmetic product above the following concentration thresholds: 0.001% (10 mg/kg) for leave-on products and 0.01% (100 mg/kg) for rinse-off products. The labelling requirement is linked to the presence of the substance in concentrations higher than the above-mentioned thresholds, irrespective of the substance’s function and irrespective of its source (i.e., whether added as such or as a component of a complex cosmetic ingredient such as botanical extracts, essential oils, fragrance compositions, aroma composition etc.). Unilever was required to list those of the 26 specific ingredients that were in Pears in concentrations greater than 0.01%. Benzyl benzoate, Cinnamal, Eugenol, Limonene and Linalool were included in the labelling because they are among the ingredients covered by Directive 2003/15/EC. It is therefore possible that they were components of the original formula, rather than newly added ingredients. 2009 change In October 2009, the formula for the transparent amber soap was altered from the original to become 'Gentle Care' and wrapped in an inner cellophane covering. The new soap was slightly softer in texture and lasted half as long, but its most noticeable difference was its scent. The aroma of the classic transparent amber bar, which used to be characterized by a mild, spicy herbal fragrance, had been altered to a stronger aromatic scent. The "Hypoallergenic, non-comedogenic" claim was dropped, and the 3-month aging process described on the original box does not appear on the
