Description

Detailed Description of the Invention

[0001] The present invention relates to a method for increasing the foaming properties of a cleaning composition comprising at least one surfactant by incorporating high fructose corn syrup into said cleaning composition.

[0002] In many cleaning applications, consumers desire high foaming power. For example, a shampoo that does not produce a sufficiently creamy and stable foam during washing is unlikely to be successful in the marketplace. The same is true for hand dish detergents, even though in many cases no direct relationship can be established between foaming power and cleaning performance.

[0003] Therefore, in addition to performance requirements such as cleaning performance and skin chemical compatibility, foaming behavior is a further important product characteristic. However, not all surfactant mixtures that work satisfactorily and are economically used exhibit the required foaming behavior.

[0004] Thus, there is a continuing need for ingredients that can increase the foaming properties of cleaning compositions without compromising the cleansing properties of the cleaning compositions.

[0005] Surprisingly, it has been found that high fructose corn syrup significantly increases the foaming properties of cleaning compositions.

[0006] Thus, in a first aspect, the present invention relates to a method for increasing the foaming properties of a cleansing composition comprising at least one surfactant, the method comprising adding high fructose corn syrup to said cleansing composition and optionally evaluating the effect thereof.

[0007] In a second aspect, the present invention relates to the use of high fructose corn syrup as a foam booster or foam promoter, in particular in a cleaning composition comprising at least one surfactant selected from the group consisting of anionic, cationic, nonionic, and amphoteric surfactants.

[0008] In a further embodiment, the present invention relates to a method for enhancing the foaming properties of anionic, cationic, nonionic, and / or amphoteric surfactants or mixtures thereof in a cleaning composition, comprising combining high fructose corn syrup with at least one surfactant.

[0009] The term "suds booster" as used herein refers to an agent that positively influences the foam characteristics of a cleanser composition in terms of foaming capacity, foam stability (foam remaining after resting for a period of time), foam quantity / volume (related to good cleaning effectiveness), foam creaminess (related to conditioning effectiveness), foam density, foam texture, and / or foam rate (foam generated after a very short period of time).

[0010] High fructose corn syrup (CAS 100843-69-4) is a well-known cosmetic agent with a unique binding mechanism to the skin that is used for short-term and long-term moisturization.

[0011] The most preferred high fructose corn syrup in all embodiments of the present invention is a) 1.5 to 5% by weight, preferably 2 to 4% by weight, of psicose; b) 1 to 5% by weight, preferably 1.5 to 4.5% by weight, of mannose; c) 10 to 30% by weight, preferably 15 to 30% by weight, of fructose; d) 20 to 60% by weight, preferably 25 to 60% by weight, of glucose, and e) 0 to 5% by weight, preferably 0 to 4% by weight, of galactose It is an isomerized sugar consisting essentially of

[0058] [Table 2]

[0059] Samples Inv-1 and Inv-2 according to the invention, containing 0.2% and 0.5% Pentavitin®, respectively, showed significantly higher foam volumes, which were also associated with faster foam formation, highlighting the excellent foam-promoting properties of high-fructose corn syrup.

[0060] [2. Opaque solid soap] In this example, a ready-to-use opaque MP solid soap base was used.

[0061] [Table 3]

[0062] procedure: - Cut the soap block into small pieces. - Place the pieces in a beaker and heat in a water bath to 65°C. - Add Pentavitin® while stirring slowly and stir for 3 minutes - Slowly pour the liquid soap into a heat-resistant plastic mold. - Once the soap has completely cooled, let it dry for at least 24 hours.

[0063] [Table 4]

[0064] The samples Inv-3 and Inv-4 according to the invention, containing 0.2% and 0.5% Pentavitin®, respectively, showed a larger foam volume, which was also associated with a faster foam formation, highlighting the foam-boosting properties of the ingredients according to the invention, the effect of which is even more significant at lower concentrations.

[0065] [3. Cream cleanser] In this example, a conventional cream cleanser was used.

[0066] [Table 5]

[0067] procedure: Mix phase A and heat to 70-75°C while stirring. Add Phase B slowly (10 min) to Phase A at 70-75°C and stir (200 rpm) at 70-75°C for 100 min. Add the amount of water lost during the heating stage (75°C). Cool to 40°C while stirring. Add C and stir until homogeneous. Add Phase D while stirring.

[0068] [Table 6]

[0069] The compositions of the present invention exhibit improved lathering properties compared to the control in both lather speed and lather volume.

[0070] 4. In vivo evaluation The following soap-based cleansers (Ref-4, Inv-6) were blindly tested on the forearms of a group of 30 volunteers during an in vivo study.

[0071] [Table 7]

[0072] For application, volunteers were instructed as follows: moisten the application area (1 forearm / product) and apply the product by gentle massage for 20 seconds, followed by a more vigorous massage for 10 seconds and leave the lather on for 1 minute, followed by standard rinsing with a sprayer (3 times) and standard drying with taped tissue (3 times).

[0073] Volunteers were asked to answer two questions regarding foam characteristics after the first application. The results of the questionnaire evaluation are summarized in Table 4b.

[0074] [Table 8]

[0075] The foam density of the inventive formulation was rated significantly higher than that of the reference formulation. Furthermore, the foam of the inventive formulation was described as not only silkier and smoother, but also less sticky and watery, reflecting an overall better foam texture.

[0076] 2. Comparative Examples with Other Sugars / Sugar Mixtures a) Preparing Compositions A and B

[0077] [Table 9]

[0078] [Table 10]

[0079] b.) Prepare solutions 1-5

[0080] [Table 11]

[0081] c.) Evaluation of foaming properties Place 5.0 g of Solution 1A and 5.0 g of Solution 1B into test tubes (height 15 cm, diameter 2.2 cm). Add 2.5g of solution 2 / 3 / 4 / 5 or water (placebo) Mark the liquid level Mix the mixture containing Solution 1A with a VWR Analog Vortex Mixer at speed 10 for 1 minute. For the mixture containing Solution 1B, shake by hand for 1 minute. Mark the height of the bubbles The difference between the surface of the liquid (before stirring) and the maximum height of the foam (foam height) is measured. The results are shown in Table 5d in mm and % relative to the placebo (set at 100%).

[0082] [Table 12]

[0083] As can be seen from the results shown in Table 5d, only the high fructose sugar according to the invention (ie Pentavitin®) significantly increases the foaming properties, independent of the respective composition.
