Description

Title of the invention: CLEANSING AND / OR MAKE-UP REMOVER COMPOSITION FOR KERATINOUS MATERIALS Technical field

[0001] The present invention relates to a composition, preferably for cleaning and / or removing makeup from keratinous materials. The present invention also relates to a method for cleaning and / or removing makeup from keratinous materials using said composition. STATE OF THE ART

[0002] Cleansing the skin or removing makeup is very important for skin care. In particular, it is very important for consumers of makeup products to have an effective makeup remover available. It must be as effective as possible because oily residues, such as dirt, excess sebum, remnants of cosmetics used daily, and makeup products, especially waterproof products, accumulate in skin folds and can clog pores and lead to the appearance of blemishes.

[0003] Several types of skin cleansing or makeup-removing products are known, for example, rinse-off anhydrous oils and gels, foaming creams and lotions.

[0004] Rinse-off anhydrous oils and gels have a cleansing or makeup-removing action due to the oils present in these formulations. These oils dissolve oily residues and disperse makeup pigments.

[0005] However, some cleansers on the market are not satisfactory, for example, they will have one or more of the following problems: discoloration during storage, poor antimicrobial capacity, does not have a fast rinsing speed and cannot deliver a good skin finish.

[0006] Therefore, there is a need to formulate compositions, preferably for cleansing and / or removing makeup from keratinous materials, that exhibit good antimicrobial capacity without discoloration problems. Furthermore, the compositions should have a rapid rinsing speed and / or provide a good skin finish. Summary of the invention

[0007] An object of the present invention is to provide a composition, preferably for cleansing and / or removing makeup from keratinous materials, which exhibits good antimicrobial capacity without causing discoloration. Furthermore, the composition has a rapid rinsing speed and / or can deliver a good skin finish.

[0008] Thus, according to a first aspect, the present invention relates to a composition, preferably for cleaning and / or removing makeup from keratinous materials, comprising: i. at least one N-acyl amino acid surfactant; ii. vanillin and / or one of its derivatives; and iii. at least one hydroxy-substituted alkyl phenyl ketone.

[0009] The inventors have discovered that the composition according to the present invention has good antimicrobial capacity and does not present any discoloration problems.

[0010] In addition, the composition according to the present invention also has a fast rinsing speed and / or can deliver a good skin finish.

[0011] According to a second aspect, the present invention proposes a method for cleaning and / or removing makeup from keratinous materials, in particular from the skin, comprising applying to the keratinous materials, in particular to the skin, the composition according to the present invention, and rinsing off said composition after an optional period.

[0077] Inventive Examples 1 and 2 and Comparative Examples 1 to 4

[0078] The compositions of Inventive Examples (IE) 1 and 2 and Comparative Examples (CE) 1 to 4 were prepared with the components listed in Table 2 (the contents were expressed as percentages by weight of active substances relative to the total weight of each composition):

[0080] The compositions of Inventive Examples 1 and 2 represent compositions of the present invention.

[0081] The composition of Comparative Example 1 does not include vanillin and / or any of its derivatives.

[0082] The composition of Comparative Example 2 does not include at least one hydroxy-substituted alkyl phenyl ketone.

[0083] The composition of Comparative Example 3 includes coco-betaine instead of at least one N-acyl amino acid surfactant.

[0084] The composition of Comparative Example 4 includes potassium myristate instead of at least one N-acyl amino acid surfactant. Preparation process

[0085] The above compositions were prepared as follows. 1. Add surfactants (sodium cocoyl glycinate or sodium cocoyl alaninate or coco-betaine or potassium myristate) and hydroxyacetophenone (if present) to a kettle and heat to 80 °C while stirring, 2. Add vanillin (if present) to the kettle at 80°C while stirring, and 3. Add water at 80°C to the kettle with stirring to obtain a homogeneous mixture, then cool the mixture to room temperature to obtain the compositions. Assessment

[0086] Each composition prepared above was evaluated in terms of bleaching, antimicrobial effect, rinsing speed, and skin finish. Bleaching

[0087] The decolorization of each composition prepared above was evaluated with the naked eye according to the following protocol.

[0088] The test samples were poured into 100 ml transparent bottles at room temperature, respectively, and discoloration was observed after 15 days.

[0089] • Success: there is no change in color.

[0090] • Failure: there is a color change. Antimicrobial effect

[0091] The antimicrobial effect of each composition prepared above was evaluated by the microbiological challenge test protocol below.

[0092] The test samples were placed in jars and the 10⁶ CFU Aspergillus Niger inoculum was added to the test samples (T₀). The Aspergillus Niger count was checked at T₀ and on Day 7 (T₇days). The Aspergillus Niger count was observed using a spiral instrument called Eddy Jet 2 and an image analyzer called Flash @ Go, produced by the company IUL.

[0093] After 7 days, if the ratio between the number of Aspergillus Niger at To / that at T7 days is greater than 500, it shows good antimicrobial capacity; if the ratio is less than 500, it shows weak antimicrobial capacity. Rinsing speed and skin finish

[0094] The rinsing speed of each composition prepared above and the skin finish delivered by it were evaluated by a panel including 6 volunteers.

[0095] The volunteers were asked to wash their face with each composition of the inventive examples and comparative examples. Rinsing speed

[0096] Approximately 1 gram of the samples was dispensed onto clean, dry hands. Two to four grams of water were added to the hands, and the samples were rubbed together and then lathered into a rich foam. The foam was applied to the face, ensuring even coverage. The face was thoroughly rinsed with water until all traces of foam were removed. The rinsing times required to complete removal (i.e., until a squeaking sensation was felt) were recorded.

[0097] The rinsing speed was noted and averaged by each volunteer according to the following standard, and its average was calculated:

[0098] 13-15: 1 to 2 times, very fast rinsing speed

[0099] 10-12: 3 to 5 times, fast rinsing speed

[0100] 7-9: 6 to 9 times, medium rinsing speed

[0101] 4-6: 10 to 14 times, slow rinsing speed.

[0102] 1-3: > 15 times, very slow rinsing speed. Skin finish

[0103] After lathering and rinsing the test composition, a tissue was used to wipe the face until it was half dry. As used here, the expression "half dry" means that there are no visible lathers or water droplets on the face, but a feeling of wetness remains.

[0104] Next, the skin finish was rated by each volunteer according to the following standard and averaged:

[0105] 13-15: Very smooth and hydrated

[0106] 10-12: Smooth

[0107] 7-9: Slightly rough

[0108] 4-6: Rough

[0109] 1-3: Dry, pulling, sensation of barrier.

[0110] The results on discoloration, antimicrobial capacity, rinsing speed and skin finish have been summarized in Table 3.

[0112] ND: not determined.

[0113] It can be seen in Table 3 that the compositions of Inventive Examples 1 and 2 can pass the decolorization test, have good antimicrobial capacity and a fast rinsing speed, and can deliver a good skin finish.
