Description

DESCRIPTION

CLEANSfNG COMPOSITION CONTATNrNG AMORPHOUS AGGLOMERATE PARTICLE TECHNICAL FIELD

The present invention relates to a composition which can efficiently cleanse the skin, while delivering skin care benefits such as: oil control, mattifying, brightening and skin homogeneity. BACKGROUND ART

The foaming cleanser is the usual product to cleanse the face. However, in hot and humid emerging countries such as India, China and Indonesia, water is often a limited resource, yet consumers have a need to repeatedly wash their face in an effort to reduce sweat and sebum build-up, as well as for religious practices.

So far, a pack type face cleansing composition comprising sebum-absorbing powder,

water-reprellant powder, a non-ionic surfactant and water is known in the art (EP 0 282 823 A2). However, it is bothersome to wait for the pack type composition to dry on the face every time even if the drying property has been improved. Furthermore, when such type of composition is used, remaining powder should be thoroughly washed off with water. This is also bothersome and cannot be said as convenient especially for the countries or areas where water is a limited resource. Furthermore, some cosmetic lotions containing polymer particles are also known in the art (US4294823 , EP 0 998 902 A 1 ). However, these cosmetic lotions are not sufficient for the cleansing ability and mattifying effect.

Therefore, there is a strong need for an on-the-go, mild cleanser to brighten, mattify, and cleanse the skin without the need to rinse, contrary to most cleansing products, that can be used multiple times during the day, particularly in countries with limited access to ninning water.

DISCLOSURE OF INVENTION An objective of this invention is to propose a composition, such as a leave-on cleansing lotion, that efficiently cleanses the skin, while delivering skin care benefits such as: oil control and mattifying, without the need to rinse. This has been achieved by combining the best associations of particles, which are able to clean and mattify the skin after application to aid in long-term oil control.

A composition with selected particles that can deliver well-perceived cleansed skin that is mattified is proposed by the present invention. In a preferable embodiment, the composition can also brighten the skin and deliver skin homogeneity.

In a preferable embodiment, after the usage of the composition, the skin feels refreshed and soft. The above objective can be achieved by a composition, preferably a cosmetic composition, comprising:

(a) from 40 to 99%, preferably from 50 to 98%, and more preferably from 80 to 95% by weight of water, relative to the total weight of the composition,

(b) at least one nonionic surfactant, and

(c) at least one amorphous agglomerate particle.

The amorphous agglomerate particle may have a specific surface area of from 5 to 400 m²/g, preferably from 150 to 400 m /g, and more preferably from 250 to 350 m /g.

The amorphous agglomerate particle may have a particle size of smaller than 30μπι, preferably from 1 to 25 μηι, more preferably from 2 to 12 μηι, and even more preferably from 3 to 6 μιη.

It is preferable that the amorphous agglomerate particle be selected from the group consisting of an amorphous agglomerate hydrated silica and an amorphous agglomerate magnesium alumino silicate.

In a preferred embodiment, the amorphous agglomerate hydrated silica may have a specific surface area of from 250 to 270 m /g and/or a particle size of from 3 to 6 μηι.

In a preferred embodiment, the amorphous agglomerate magnesium alumino silicate may have a specific surface area of from 320 to 340 m /g and a particle size of from 10 to 12 μιη.

In a preferred embodiment, the HLB value of the nonionic surfactant may be more than 8, more preferably more than 9, and even more preferably more than 10.

In a preferred embodiment, the nonionic surfactant be selected from the group consisting of PEG-6 caprylic/capric glycerides or peg-7 caprylic/capric glycerides, PEG-12 dimethicone, Polysorbate'80^PP©-6-decyltet ^"adeceth-30 and* PPG- 10 methyl glucoside.

The amount of the nonionic surfactant may be from 0.005 to 20 % by weight, more preferably from 0.01 to 5% by weight, relative to the total weight of the composition.

The amount of the amorphous agglomerate particle may be from 0.005 to 20 % by weight, and preferably from 0.1 to 5% by weight, relative to the total weight of the composition.

It is preferable that the composition of the invention further contain kaolin or kaolin derivatives.

It is preferable that the concentration of kaolin or kaolin derivatives in the composition be from 0.1 to 5 % by weight, and more preferably from 0.5 to 2 % by weight, relative to the total weight of the composition.

In a preferred embodiment, the composition of the invention may further comprise at least one organic polymeric particles such as methyl methacrylate cross-polymer hollow particle. It is preferable that the concentration of the organic polymeric particle(s) in the composition be from 0.1 to 5 % by weight, and more preferably from 0.5 to 2 % by weight, relative to the total weight of the composition. The present invention also relates to a non-therapeutic cosmetic method for cleansing and/or mattifying the skin and/or brightening the skin and/or delivering skin homogeneity, comprising applying the composition according to the invention.

(Amorphous Agglomerate Particles)

The amorphous agglomerate particle of component (c) can be defined as clusters of particles held together by weak physical interactions, and may be more broadly and simply defined as a mass of particles.

The amorphous agglomerate particles have no real defined structure versus particles that have a clearly well-defined structure, such as spheres, crystals, and blocks. The specific surface area per unit of mass of the amorphous agglomerate particles may be determined by BET theory. Brunauer-Emmett-Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of a material. The specific surface area of the amorphous agglomerate particle of component (c) may be from 5 to 400 m /g , preferably from 150 to 400 m /g, and more preferably from 250 to 350 m /g. In a preferable embodiment, the amorphous agglomerate hydrated silica may have a specific surface area of from 250 to 270 m²/g. In a preferable embodiment, the amorphous agglomerate magnesium aluminum silicate may have a specific surface area of from 320 to 340 m²/g. The particle size of the amorphous agglomerate particle in the finish product of the composition (i.e. in a liquid composition) may be smaller than 30 μηι, from 1 μιιι to 25 μπι, preferably from 2 to 14 μιη, more preferably from 2 to 12 μιη, and even more preferably from 3 to 6 μηι. The particle size of the amorphous agglomerate particle means the median of secondary particle diameter of the amorphous agglomerate particle. In a preferable embodiment, the particle size of the amorphous agglomerate particle may be from 3 to5 μπι and from 10 to 12 μιη.

In a preferred embodiment, the amorphous agglomerate hydrated silica may have a specific surface area of from 250 to 270 m /g and/or a particle size of from 3 to 5 μιη. In another preferred embodiment, the amorphous agglomerate magnesium aluminum silicate may have a specific surface area of from 320 to 340 m²/g and/or a particle size of from 10 to 12 μηι.

In a preferred embodiment, oil adsorption of the amorphous agglomerate particle may be from 2.5 g to 4.5 g oil adsorption / g particle. The amorphous agglomerate particles may be composed of material selected from the group comprising silicas, especially amorphous hydrated silicas, magnesium alumino silicate, aluminas, calcium carbonates, dicalcium phosphate, tribasic calcium phosphates, hectorites, saponites, aragonites, dolomites, talcites, hydroxytalcites, spangolites, zincites, zincosilicates, insoluble metaphosphates, calcium pyrophosphates, hydroxyapatites, perlites, zeolites, clays, magnesium carbonate, pumice and volcanic ash, or mixtures of two or more of these components.

Protocol for the evaluation of technical effect of said compositions Cleansing Ability Evaluation (on forearm)

1. A 2.5 x 2.5 cm² squares supplare (black leather) was used for the evaluation of each composition.

2. To start the testing, a baseline was measured with a portable colorimeter (ex: spectrophotometer Konica Minolta CM-700d) directly on the bare skin and (L, a, b) coordinates of the bare skin were obtained.

3. (Make-Up) : 30 mg of a foundation was put on each supplare and spread evenly within the square. A measurement was taken of the (L, a, b) of {skin + foundation} with the portable colorimeter to obtain a before cleansing value.

4. (Removing the make-up) 1 gram of the composition of one of the example 1 to 5 or comparative examples 6 to 12 was put on a cotton pad (ex. ALX, SAP code 5235101020,

Alexandre Cotton N). The cotton pad is then applied and rubbed against each spot with a circular movement during 30 seconds.

5. Each triplet (L, a, b) of {skin + foundation after cleansing} was measured with the portable colorimeter after removing the foundation. Then, the cleansing ability was evaluated as follows:

6. Calculation of cleansing ability: AE_max = maximum value corresponding to the case where make-up is removed totally compared with the bare skin

Where, Aa_t = a bare skin - a {skin + foundation}

Abi = b bare skin - b {skin + foundation}

ALi = L bare skin - L {skin + foundation}

For each formula, calculations of AE_mean were conducted for 2 spots:

Where, Aa₂ = a cleansed skin - a {skin + foundation}

Ab₂ = b cleansed skin - b {skin + foundation}

AL₂ = L cleansed skin - L {skin + foundation}

Finally, cleansing ability percentage (Cleansing Efficacy) was calculated by the following formula.

Mattifying Effect Evaluation

Each composition was spread beforehand at room temperature on a supplare (skin model black leather) at a rate of 2 mg/cm². The deposits are then dried at 37°C for 60 minutes. By using a goniophotometer, calibrations and light intensity measurements were performed respectively with a matt standard plate made from barium sulfate and with the contrast card coated with the make-up base. The mattifying efficacy (R_gain) is then evaluated from the ratio R of the specular reflection (measured at angle 30°) and the diffuse reflection (measured at angle 0°). A low value of R means a high mattifying effect. If R is inferior to 2, there is no improvement of skin aspect.

The results are shown in Table 2.

Table 2

Median particle size in liquid environment was measured with Mastersizer 2000. Each particle was dispersed in the water phase in the example. Upon focusing on the relationship of specific surface area and the mattifying and cleansing effects, in general, formulas that contain particles with specific surface areas with the range of 250 - 350 g/m² demonstrated the best mattifying and cleansing effects.

Comparing the Examples 2, 4, 5 and Comparative Example 2, which are using silica particles, the mattifying efficacies (%) are above 40% in Examples 2, 4, and 5 whereas the efficacy is 38% in Comparative Example 2. The cleansing efficacies are above 50% in Examples 2, 4 and 5 whereas the efficacy is 32% in Comparative Example 2. These results indicate that remarkable mattifying and cleansing effects can be obtained by using amorphous agglomerate silica particles in the composition.

Oil control, brightening and skin homogeneity effects were also evaluated by applying the cosmetic compositions selected from Examples 1 to 5 and Comparative Examples 1 to 5 to the skin of subjects. The cosmetic composition selected from Example 1 to 5 showed obviously superior effects for oil control, brightening and skin homogeneity than that selected from Comparative Examples 1 to 5.
