Description

Composition for cleaning and/or removing make-up from keratin materials

Technical Field

The present invention relates to cosmetic compositions. More particularly, the present invention relates to a composition for cleansing and/or removing makeup from keratin materials. The invention also relates to a method for cleaning and/or removing makeup from keratin materials.

Background

Cleansing the skin and removing color cosmetics from the skin are very important for skin care. In particular, it is very important for consumers of cosmetic products to have an effective makeup remover. It must be as effective as possible, since greasy residues (e.g. dirt, excess sebum), residues of cosmetic and make-up products in daily use (especially water-repellent products) accumulate in the skin folds and can block the skin pores, leading to the appearance of spots.

Several types of makeup removal or cleansing products are known, such as flushable cleansing anhydrous oils and gels, solid makeup removers, or dual phase makeup removers and wipe-type makeup removers.

Flushable anhydrous oils and gels have a make-up removal effect by virtue of the oils present in these formulations. These oils make it possible to dissolve the fatty residues and to disperse the cosmetic pigments. These products are effective and well tolerated. However, they exhibit the disadvantages of being massive and not imparting a fresh feel upon application, which is disadvantageous from a cosmetic point of view.

Two-phase makeup removers are effective, but are inconvenient to use because shaking is required before each use, and the two phases are consumed at different rates.

The makeup remover leaves a fresh feeling, but is inefficient. Cleansing milks are also considered inefficient. Balms/creams have a greasy feel, are not suitable for use in the eye region and are not hygienic. The wipe-type makeup remover is convenient but inefficient against water-repellent makeup and is not hygienic.

In the field of make-up removing compositions, "soft solid" compositions constitute a class of products which are appreciated by consumers for their cleansing efficacy, make-up removing ability, rinsing ability, and their cosmetic qualities (softness, dry feel, ease of use, etc.). They are known as solid compositions which soften under stress, such as by spreading on the skin surface or, for example, by extrusion from a device with perforated walls (a grid). Some known soft solid compositions useful for cleansing the skin and/or removing makeup comprise silica aerogel particles, a wax, a hydrocarbon-based oil, and a nonionic surfactant. However, it is difficult to apply the soft solid composition to the skin.

Today, cleansing compositions provide effective cleansing of keratin materials and mildness to the eye and keratin materials, making it increasingly important that the keratin materials be fresh and clean.

There is therefore a need for compositions formulated for cleaning and/or removing make-up from keratin materials, which have a texture that is easy to use, good cleaning performance, no irritation to the eyes and to the keratin materials, and which make the keratin materials fresh and clean.

Summary of The Invention

The aim of the present invention is to provide a composition for cleaning and/or removing makeup from keratin materials, which has a texture that is easy to use, good cleaning properties, is non-irritating to the eyes and to the keratin materials, and leaves the keratin materials fresh and clean.

Thus, according to one aspect, the present invention provides a composition for cleaning and/or removing makeup from keratin materials, comprising:

a) at least one anionic surfactant selected from dialkyl sulfosuccinates; and

b) at least one nonionic surfactant selected from alkylpolyglycosides of formula (I):

R-O-G_x’ (I)

wherein

R is C₆-C₄₀An alkyl group, a carboxyl group,

g is a moiety derived from a reducing sugar containing from 5 to 6 carbon atoms,

x' is the average degree of polymerization of the alkylpolyglycoside of 1 to 10.

Such compositions are intended for cleaning and/or removing make-up from keratin materials, in particular the skin.

Thus, according to another aspect, the present invention provides a method for cleansing and/or removing make-up from keratin materials, in particular the skin, comprising applying to the keratin materials, in particular the skin, a composition according to the invention and rinsing off the composition after a random period of time.

The composition according to the invention enables the skin to be refreshed and cleaned without any harsh feeling.

The composition according to the invention also exhibits cream-oil-foam transition and delivers good rinsability during application.

It can be used as daily face cleaning agent. The compositions of the present invention are rinse-off products. Thus, such compositions are applied to the skin (i.e., face and/or body) and then rinsed with rinse water.

the composition was prepared as follows:

the ingredients for phase A were mixed with a dispenser at a stirring speed of 200rpm and heated to 65 ℃. The heating was stopped and the ingredients for phase B were added to phase A and emulsified for 10 minutes. Once the mixture was cooled to 50 ℃, the stirring speed was increased to 500rpm, the ingredients for phase C were added and mixed for 10 minutes. The mixture was cooled to room temperature under a stirring speed of 200 rpm.

Example 2: evaluation examples

The compositions prepared in example 1 were evaluated for texture, makeup removal ability, foaming properties and skin/eye irritation.

The makeup removal ability was evaluated based on the following protocol.

(i) Pretreatment of biological skin:

biological skin was washed with Shu Uemura Ultima 8 cleansing oil (Shu Uemura Ultima 8 cleansing oil) and then with Lifuquan super Anjie cleansing foam cream (LRP toleriane cleansing foaming cream).

(ii) Application of waterproof mascara:

megbaolian (Maybelline) (Hyper Curl volume Express waterproof mascara) was applied to biological skin at 0.05g per 5cmx5cm biological skin.

(iii) Drying was carried out at 32 ℃ for 10 minutes.

1g of the composition to be tested is applied with a gentle massage of 100 cycles, rinsed off with running water and dried with a paper towel by patting.

Photographs were taken with dermoscore + and the images were analyzed to detect the percentage of dark pixels in the photographs. A lower score indicates less makeup residue left on the biological skin and therefore better makeup removal.

The score of makeup removal ability was given based on the following criteria.

Dark pixel%	0-0.5％	0.5-1％	>1％
				Makeup removing ability	Good taste	In	Difference (D)

Skin/eye irritation was evaluated based on the following protocol.

The compositions were tested by 10 consumers as follows:

(i) applying the composition to be tested on dry face with dry hands;

(ii) massaging in a looping way to dissolve color cosmetics on the face;

(iii) adding water to foam and completely washing;

(iv) the consumer is asked whether the composition has skin/eye irritation during each step.

The score for skin stimulation is given based on the following criteria.

Number of consumers claiming irritation	0	1-3	>3
				Level of stimulation	Is low in	In	Height of

The presence or absence of cream-to-oil transition was observed by sensory perception during application.

Foaming performance was evaluated by 10 consumers aged 20 to 40 years using the following procedure:

(i) applying the composition to be tested on dry face and massaging in a loop;

(ii) wetting the face with water creates lather for better cleansing;

(iii) washed off with water.

The score for foaming performance is given based on the following criteria:

and 5, dividing: at least 80% of consumers believe the effect is good and expected;

and 4, dividing: 60% to 80% (excluding 80%) of the consumers considered to be good and expected;

and 3, dividing: at least 50% of consumers believe the effect is good and expected;

and 2, dividing: over 60% of consumers consider the effect poor and unacceptable;

1 minute: results that are considered poor and unacceptable by more than 80% of consumers are as follows:

item	Inv.1	Inv.2	Comp.1	Comp.2
					Texture of	Elastic cream	Elastic cream	Fluid emulsions	N/A, cannot be prepared
Removal capability	Good taste	Good taste	In	N/A
					Skin/eye irritation	Is low in	Is low in	N/A	N/A
Cream-to-oil conversion	Is that	Is that	Whether or not	N/A
					Volume of foam	5	4	4	N/A

N/A: not tested.

From the results listed above it is clear that the composition according to the invention shows a much better rinse stability compared to the comparative composition. At the same time, the compositions according to the invention do not cause irritation to the skin and the eyes.

It has also been found that the composition according to the invention shows a cream-to-oil transition during application and is capable of refreshing and cleansing the skin.

While illustrative embodiments of the invention have been described above, it will be understood, of course, from the foregoing description that various modifications will be apparent to those of ordinary skill in the relevant art or may become apparent as the technology advances. Such modifications are to be considered within the spirit and scope of one or more of the inventions disclosed in this specification.
