Problems solved by technology

However, this task is often difficult because the odor-causing chemicals trigger extremely strong odors and have much lower detection thresholds than the odorant / perfuming compositions typically used to mask them

Embodiment 1

[0133] Example 1: Characterization of Raw Odor in a Representative Laundry Soap Base

[0134] A behavioral sensory evaluation method called Quantitative Descriptive Analysis (QDA) developed by Tragon Corporation in 1974 was used to identify and characterize raw odor present in seven representative laundry soap bases. QDA uses descriptive panels to measure sensory characteristics of products. Panelists use their senses to identify perceived similarities and differences in products and express those perceptions in their own words.

[0135] During language development, group members receive products to describe them. All generated terms were then evaluated on a 6-point non-linear scale from 0 (no odor perceived) to 5 (strong odor). To reduce the list of attributes, Dravniek means were calculated and multidimensional and ANOVA were run. Sixteen sensory terms were identified to describe the raw off-flavors present in seven representative laundry soap bases (assessed neat): tiare...

Embodiment 2

[0143] Example 2: Characterization of off-flavor antagonist systems according to the morphologies presented herein

[0144] The sensory terms attributed to the representative laundry soap bases identified and described in Example 1 above are the result of the presence of certain off-flavor molecules in the headspace surrounding the laundry soap base. Figure 8 The ability of the following odor counteracting compositions to reduce the headspace concentration of ethylhexyl acetate (earth, dirty odor profiles) and 2-undecanone (oily, waxy odor profiles) is reported.

[0145] IUPAC name Amount (wt%) common name Propane-2-yl myristate 22％ 1-(2,6,6-Trimethyl-1-cyclohex-2-enyl)pent-1-en-3-one N- 15％ 3a,4,5,6,7,7a-hexahydro-4,7-methinden-6-yl acetate 10％ (±)-3,7-Dimethyl-1,6-octadien-3-ol 6％ 2,6-Dimethyloct-7-en-2-ol 4％ other 43％

Embodiment 3

[0146] Example 3: User testing of laundry soaps treated according to the methods disclosed herein

[0147] The odor counteracting compositions described herein were tested for their ability to limit, reduce or eliminate raw odor perception to commercial laundry soap bases by users in Nigeria (skin cleansing base) and Côte d'Ivoire (laundry base). The ability of the odor counteracting composition to limit, reduce or eliminate the perception of raw odor was evaluated in dry soap powder in the box (pure state) and using wet towels soaked in laundry detergent solution for 10 minutes prior to evaluation ( wet to simulate the product in use).

[0148] In the first study conducted in Côte d'Ivoire, users were asked to evaluate a benchmark base without any perfuming composition (CDI base), a benchmark base containing 0.35 wt% aloe chamomile fragrance (CDI base aloe chamomile 0.35 %) and a benchmark base containing 0.31 wt% Optima fragrance (CDI base Optima 0.31%), and they were asked...

Abstract

The present disclosure relates to the field of off-taste cancellation. More specifically, the present invention relates to compositions that limit, reduce or eliminate the perception of off-taste associated with soaps or soap bases. Such compositions include (i) an off-taste antagonist system associated with a perfuming ingredient as an off-taste counteracting agent, and (ii) at least one off-taste neutralizing system, the combination of which significantly reduces off-taste perception associated with soaps or soap bases. Such compositions, their use in combination with delivery systems, and their use in consumer products are objects of the present disclosure.

Description

technical field [0001] The present disclosure relates to the field of malodor (malodor) countermeasures. More specifically, it relates to compositions that limit, reduce or eliminate off-flavor perception associated with soaps or soap bases. Such compositions include (i) an odor antagonist system associated with a perfuming ingredient as an odor counteracting agent, and (ii) at least one odor neutralizing system, the combination of which can significantly reduce odor associated with soaps or soap bases perception. Such compositions, their use in combination with delivery systems, and their use in consumer products are the object of this disclosure. Background technique [0002] Odors perceived as odors are present in many environments and can be experienced in our daily lives. Off-flavors are often complex mixtures of more than one off-flavor compound, which can often include various amines, thiols, sulfides, short-chain aliphatic and unsaturated acids such as fatty acids...
