Embodiment 1
[0112] Example 1: Evaluation of coloration of deodorant formulations in accordance with some of the modalities presented herein. Preparation of an antiperspirant spray formulation: Using a high-speed agitator, combine silica (Table 1) and quaternary ammonium-18-hectorite ( Table 1) was added to a mixture of isopropyl myristate (Table 1) and cyclomethicone (Table 1). Once fully swollen, aluminum chlorohydrate (Table 1) was added in portions with stirring until the mixture was homogeneous and free of lumps. The aerosol can was filled with 25% suspension and 75% propane / butane (2.5 bar).

Embodiment 2
[0189] Example 2: Sensory evaluation of spray deodorant formulations according to some of the modalities presented herein
[0190] will contain the specified amount as -D a commercially available β-thiocarbonyl derivative fragrance precursor of formula (I) fragrance formulation 1, or containing as -I A test formulation of a commercially available beta-thiocarbonyl derivative fragrance precursor of formula (I) Fragrance Formulation 1 was formulated as a deodorant spray.
[0191] One gram of each test formulation was applied to a separate 2-3 year old cotton T-shirt. Meanwhile, a control formulation containing only the fragrance formulation (ie, lacking the beta-thiocarbonyl derivative fragrance precursor of formula (I)) was similarly applied to individual t-shirts.
[0192] In a blinded, balanced, randomized study, a minimum of 18 skilled panelists were asked to evaluate the fragrance intensity of the slides with 20 seconds between samples.
[0193] Panelists were asked to...
Embodiment 3
[0197] Example 3: Sensory evaluation of spray deodorant formulations according to some of the modalities presented herein
[0198] A test formulation was prepared containing Fragrance Formulation 1 containing 1.5% as -D commercially available beta-thiocarbonyl derivative fragrance precursors of formula (I). One gram of each test formulation was applied to a separate 2-3 year old cotton T-shirt. At the same time, a control formulation containing only Fragrance Formula 1 was similarly applied to individual t-shirts.
[0199] In a blinded, balanced, randomized study, a minimum of 18 skilled panelists were asked to rate formulations for fragrance intensity and perceived malodor intensity, with a 20-second interval between samples.
[0200] 15 minutes before the study, 0.20 grams of the sweat odor solution was applied to the T-shirt. Panelists were asked to (i) rate the scent intensity from 0 (imperceptible) to 10 (very strong odor), and (ii) rate the perceived malodor intensity ...
