Problems solved by technology

Also, fragrances within a product often have a shorter lifespan than the product itself
Therefore, the masking of malodors during the entire product life cannot be achieved

Embodiment 1

[0078] Emulsions (i.e. skin care compositions) containing CLA {50% cis 9, trans 11 and 50% trans 10, cis 12} were prepared by mixing CLA, sodium lauryl sulfate (about 0.6%) and water to prepare. The resulting mixture was stirred on a stir plate for about 20 minutes to dissolve the SDS into solution. SDS solution with dispersed CLA using Ulbra Cell TM The sonicator sonicates for about 2 minutes to create a stable emulsion. By adding 2% DPG to complete the first stable emulsion, by adding 2.5% clay ( grade XLG) to complete the second stable emulsion and by adding 2% DPG and 2.5% clay ( Grade XLG) completes the third stable emulsion. All completed emulsions were sonicated for an additional 2 minutes. There was 3% CLA in each emulsion, water was added to balance, all percentages are by weight based on the total weight of the emulsion.

Embodiment 2

[0080] Headspace analysis was performed on the CLA emulsion prepared in Example 1. Solid Phase Microextraction (SPME) - Gas Chromatography (GC) 6890 / Mass Spectrometry (MS) 5973 / Flame Ionization Detector (FID) from Agilent was used to determine the ) of the emulsion vapor (ie, the aldehyde resulting from, for example, the oxidation of CLA). 1 gram of each of the above emulsions was added to 20 ml GC headspace vials sealed with caps and septa. The GC column used was a HP-5MS column from Agilent (inner diameter 0.25 mm, length 30 m, stationary phase thickness 0.25 μm). The GC conditions were such that the injector was in splitless mode with helium as the carrier gas. The injection port was heated to 250°C and purged with a purge flow of 50 ml / min with a split evacuation for 2 minutes. The column was set in constant flow mode at 1.3ml / min. The furnace temperature slope was kept at 75°C for 2 minutes, and raised to 100°C at a rate of 6°C / min, 150°C at 1.5°C / min, 190°C at 3°C / mi...

Abstract

Malodor free skin care compositions are described. The skin care compositions comprise an adsorbable solvent and an insoluble particle in an adsorbable solvent-insoluble particle complex. The complex is suitable to adsorb components with malodor to yield a skin care composition free of offensive odors like those generated from the oxidation of conjugated linoleic acid.

Description

[0001] This application entered China on August 21, 2009, the Chinese application number is 200880005879.1 (international application number: PCT / EP2008 / 051778, international publication number: WO2008 / 101852), and the invention title is a PCT application for "deodorization of cosmetics" divisional application. technical field [0002] The present invention relates to skin care compositions and methods for reducing malodor in skin care compositions. More particularly, the present invention relates to skin care compositions containing insoluble particles suitable for use in absorbent compositions like lotions, creams and body washes that have been shown to produce irritating Nasty unpleasant-smelling compounds. The insoluble particles are preferably used together with an adsorbable solvent which is suitable to be adsorbed on the insoluble particles, whereby the composition comprising the insoluble particles and the adsorbable solvent surprisingly exhibits deodorization and, in...
