Description
A Mild Cleansing Composition Distributable from a Pump Foamer
Technical field
The present invention belongs to the cosmetic field, and relates to a cosmetic cleansing composition, especially a cosmetic cleansing composition releasable as a foam from a packaging device having a foam pump. Furthermore, the composition is distributed from the packaging device in form of a dense and creamy foam, which is used to cleanse the skin, especially the face skin, mild and thoroughly.
Background art
Cleansing compositions in form of a self-foaming cleanser are very popular today, especially in North Asia.
In general, cleansing products are supposed to cleanse the skin and hair. Cleansing products for the skin are primarily used to remove dirt from the skin surface. External solid or liquid components, which came into contact with the skin and were deposited thereupon or components applied to the skin, for instance as make-up, are part of the dirt on the skin, which is to be removed. Furthermore, the dirt on the skin also includes excess skin lipids and dead cells. By the aid of surfactants in the cleansing compositions, the components of the dirt are solubilized and removed from the surface of the skin during rinsing off. This also holds true for make-up, which shall be removed from the skin, hair, and skin appendages, and in particular from the face.
Cleansing compositions intended for face cleansing have to meet special requirements. As the skin of the face is a very sensitive part of the skin, the eye area and the eyes being even more sensitive, cleansing compositions for face cleansing have to be compatible to the skin of the face and the eyes. Therefore, the compositions have to be mild ones.
Moreover, cleansing compositions released from the packaging device as a foam are very appreciated by the consumers. Such cleansing compositions may be distributed on the skin very easily, without the necessity of intense rubbing, which may lead to skin irritations.
Mild cleansing compositions are known from prior art. EP 2468246 A1 discloses skin cleansing compositions exhibiting a low irritation characteristic, which contain polyglyceryl
esters of fatty acids and anionic surfactant and/or amphoteric surfactants, the latter ones may have a betaine portion.
A Volcanic Mattifying Cleansing Cream (Mintel Data Base, number: 7530121 ) being available since April 2020, is described to be hypoallergenic. This cleansing cream contains a polyglyceryl ester of myristic acid and an amphoteric surfactant, namely coco-betaine.
A Blemish Cica Gel Cleanser (Mintel Data Base, number: 8449291 ), which may be purchased since January 2021 , describes a gel cleanser for sensitive skin. This cleansing gel contains a polyglyceryl ester of capric acid and an amphoteric surfactant, namely coco-be- taine.
As shown above, prior art discloses different forms of cleansing compositions, e.g. a cleansing cream or a cleansing gel. However, it is desirable to provide the cleansing composition in form of a foam.
The product Sublime Beauty Cleansing Oil-in-Foam (Mintel Data Base, number: 7955377) discloses a foam containing a considerable amount of oils and is intended to thoroughly and quickly remove impurities, excess sebum, and long-lasting make-up. Hence, this product is described to have a good cleansing performance.
The aim of the present invention was to provide a cleansing composition, forming a dense and creamy foam upon release from the packaging device and at the same time being very mild to the skin.
To achieve a dense foam, in general a high amount of surfactants is used, even surfactants in form of soaps. However, these high amounts of surfactants may cause irritations of the skin and the respective compositions are not perceived as mild ones. Hence, a balance between the mildness of the cleansing composition and a dense and creamy foam had to be found.

The term "natural" in connection with natural ingredients for cosmetics is specified in ISO 16128; the first part of ISO 16128-1 was published on February 15, 2016, the second part of ISO 16128 2 was published in September 2017. According to this guideline, natural, cosmetic ingredients can be summarized as substances that are available from plants, animals, minerals or microorganisms, including those substances that are obtained from the above-mentioned sources by physical processes, fermentation processes (only those fermentation processes that are also used to occur in nature and lead to products that are also obtained in nature), and other manufacturing methods without chemical modification. The microorganisms may only be those that have not been genetically modified.
In general, nature-based substances are compounds that are derived from natural starting materials or are produced starting from natural starting materials. In order to assess the extent to which a substance is nature-based, the method for determining the "Biorenewable Carbon Index" (= BCI) may be used. This method is used to determine the percentage of carbon atoms that come from renewable plant or animal sources in relation to the carbon atoms from non-renewable, petrochemical sources, see HAPPI July, 58-60, 2009.
The term "free from" is intended to mean a composition containing less than 0.1 % by weight, preferably less than 0.01 % by weight, more preferably 0.001 % by weight, most preferably 0 % by weight, of a respective component, relative to the total weight of the composition.
The composition of the invention is contained in a packaging device, having a container and spraying means. Advantageously, the spraying means is a spray pump having the characteristic elements for such pumps, such as spray head, nozzle, piston, turret, cone, seal, fitting, sleeve, spring, housing and riser. Suitable spray pumps may be purchased, for example, from DERJIN (JIANGSU) PLASTIC PACKAGE CO., LTD. with the name self-foaming pump. The complete packaging device, which is very suitable for the present invention, may be called pump foamer.
The containers are advantageously made of plastic, in particular PET or PE. Likewise, containers of glass or metal are suitable.
In order to analyze the mildness of the composition according to the invention and of two comparative compositions a shortened epicutaneous patch test was conducted. Said composition, PFOAM 1 70 (example 1 ), the two comparative compositions and a positive control (internal standard; 0.1 % SDS) were applied to the back of the subjects. 29 subjects ranging from 22 to 66 years of age took part in the study; 12 subjects having a highly SDS sensitive skin (41 %), 14 subjects having a SDS sensitive skin (48 %) and 3 subjects having a less / not SDS sensitive skin (10 %).
The test products as well as internal standard were applied to the subjects' backs, where they remained for 6 hours. The application sites were visually assessed approximately 18 hours after removal of the patches in accordance with the Global Irritation Scale. The application was repeated up to 4 times, or up to the first sign of skin irritation (score > 1 ).
Test products were applied with occlusive patches (Type Leukotest, Beiersdorf AG). The diameter of the patch is 1 cm, providing an exposure area of 0.79 cm2. 100 pl of the test product was applied to the patches with a pipette. All test patches were affixed to the upper back, where they remained for 6 hours (days 1 , 2, 3 and 4), respectively. In order to avoid irritant reactions to the skin adjacent to the patches, two Fixomull stretch templates (BSN, 15 cm x 10 cm) with five (left) or three (right) 25 mm diameter holes were used to protect the skin adjacent to the test area over the entire test period. The holes in the template had a minimum distance of 4 cm to each other's center. The templates were placed directly onto the back. The application was repeated up to 4 times, or up to the first sign of skin irritation (score > 1 , see below).
Visual scoring took place in accordance with the Global Irritation Scale 18 hours after removal of the patches.
* 6 hours after application of the test product or internal standard.
** by a trained evaluator, 18 hours after patch removal.
After removing the test patches, the skin was assessed visually by an experienced person with regard to the occurrence of any skin irritation (e.g. erythema).
*No further product application;
** according to the International Contact Dermatitis Research Group.
Formula calculation for the Irritation Index: number of erythema x 4 + number of erythema
1 + number of erythema x 0.5 + number of erythema
0.5.
"Day1 st score" is referring to the first day of visual evaluation, this day corresponds to "Day 2" of the epicutaneous patch test. The same holds true for the "Day2nd score", which was determined on "Day 3" of said test, "Day3rd score", which was determined on "Day 4" of said test, and "Day4th score", which was determined on "Day 5" of said test.
The inventive example (PFOAM 170) is a very mild composition as the epicutaneous patch test revealed.
In a further step a home in use test was conducted as a blind and monadic test. The product according to the invention (example 1 , PFOAM 1 70, F17) was evaluated by 154 female users (50% having the age of 18 to 25 and 50 % having the age of 26 to 35) living in two different cities. In parallel, three other products were evaluated, the product M31
(= PFOAM 1 73) by 154 female users, the product P65 (= PFOAM 165) by 155 female users and the competitor product by 155 female users. The comparative products, M31 and P65, were products according to the formulas shown in the table of comparative formulas.
The competitor product was the product Curel Intensive Moisture Care Foaming Wash (Mintel Data Base, number: 7976579), containing the following ingredients according to the INCI listing: water, glycerin, maltitol, propylene glycol, PEG-150, sodium cocoyl glutamate, sodium lauroyl aspartate, lauryl hydroxysultaine, polysorbate-60, ethylhexylglycerin, disodium EDTA, dipotassium glycyrrhizinate, potassium hydroxide, methylparaben, phenoxyethanol.
Several aspects were to be evaluated, such as overall liking, overall performance, and performance on key aspects (foam, fragrance, cleaning effects, rinsing, skin feel during wash, skin feel after wash, mildness).
Referring to overall liking and overall performance the product according to the invention (example , PFOAM 170, F17) and the product according to the example PFOAM 173 were evaluated best, both products with similar results.
In relation to the above mentioned key aspects the product according to the invention was evaluated better in some aspects as PFOAM 1 73, namely fragrance, cleaning effect, rinsing, and mildness. Despite the fact that the product PFOAM 173 was evaluated better than the product PFOAM 1 70 referring to the aspect of foam, the foam of the product according to the invention is nevertheless evaluated better than the competitor product on the market, namely R52 (= Curel). Moreover, by farthe majority of the users described the creaminess of the foam as just right and also the thickness of the foam as just right in relation to the product according to the invention. Hence, a solution to the problem to provide a product for face cleansing, being mild to the skin and having a dense and creamy foam could be shown.
Examples;
The examples below are intended to illustrate the present invention without limiting it. The numerical values in the examples are percentages by weight, based on the total weight of the particular preparations, given as active content.
