Description

Detergent Composition

The present invention relates to detergent compositions suitable for topical use to clean the human body and remove grease, in particular for removing makeup from the skin. More specifically, the present invention relates to a composition formulated to provide the benefit of a clean, refreshing skin feel, generally associated with a foaming cleanser, while effectively removing makeup from the face.

Compositions formulated to remove makeup from the skin are well known. They generally contain large amounts of solvents, such as cosmetic oils, which are effective in penetrating and dispersing the oily layer of the wax and pigment particles that make up makeup. Such make-up remover compositions may be designed to be wiped off, for example using cotton pads, or may be designed to be rinsed with water, in which case the composition may be a surfactant for the simultaneous emulsification of the makeup base and solvent oil. It may contain.

In general, however, makeup removers formulated as such or as water-in-oil or oil-in-water emulsions have been found to leave a greasy after-feel to the skin. In addition, they may not form bubbles or only very few bubbles during washing off. Consumers prefer to have a clean, fresh skin feeling after washing. To achieve this result, especially with thick makeup, it is often a double cleaning process.

Common foaming cleansers, such as well-known soap bars, facial washes, bath foams, shampoos and shower gels, form rich foams when mixed with water, and when light from the skin (eg Removes sebum, leaving a clean and refreshing skin feeling. However, these products may be rather ineffective at removing thick stains, such as makeup, and may also cause the skin to be too dry.

Recently, a new type of "two-in-one" claimed to combine the benefits of effective makeup removal with the ease of rinsing, foaming and skin feel attributes generally associated with foaming cleansers. Cleanser came out. However, the failure of these products to secure a large market share is due to the need for compromise in formulation. That is, known "two-in-one" cleansers derived from conventional facial foam formulations were not able to completely remove makeup, and "two-in-one" cleansers derived from conventional makeup remover formulations. Could not provide the sensory benefits associated with sufficiently clean, fresh skin.

It is also known to formulate another class of "to-in-one" products that provide both cleaning and moisturizing benefits from different product phases. For example, WO 96/02230 discloses a composition comprising a surfactant and a useful agent in which the surfactant and the useful agent are separated but can be distributed together in a predetermined proportion from a single packaging means to separate domains. It was. It is described that sedimentation of the useful agent can be improved by separating the useful agent from the surfactant. However, WO 96/02230 focuses primarily on depositing substances on the skin, while the present invention achieves the opposite effect of removing the substances from the skin.

One of the problems usually encountered with such two-use compositions is that the remover component content is insufficient or the amount of effective action during use is insufficient, resulting in unsatisfactory removal of thicker times, such as makeup compositions.

Another problem associated with such dual-use cleaning and moisturizing or degreasing compositions is instability. According to WO 94/03152 for shower gels containing non-soap cleaners, silicone oils and cationic polymers, the maximum average droplet size of silicone oil that can be used when product stability is to be maintained is 2 microns. to be. However, since it is important that the product show no signs of alteration when stored for a period of time, the stability concept extends to all aspects of the formulation including dyes and antimicrobial stability.

Another problem associated with the cleaning compositions of the prior art is their low foaming capacity. A lot of foam along with excellent foam quality is an important attribute that can greatly affect user's perception of product quality and effectiveness.

The inventors have found a way to formulate compositions which can still provide the sensory benefits associated with foam forming cleansers while providing effective oil removal, in particular good makeup removal.

In addition, the present inventors provide a composition in which the cleaning component and the removal component are separated but can be distributed together from the packaging means into separate domains, thereby improving the stability and removal agent delivery and effectiveness of the two-use product for cleaning and degreasing. Came to discover that.

Thus, according to the first aspect of the present invention,

a) a first component containing an aqueous domain containing at least one surfactant selected from anionic, nonionic, amphoteric, zwitterionic and cationic surfactants, soaps and mixtures thereof, containing this surfactant The composition contains an effective amount of a short chain polyol grease remover); And

b) a second component containing a non-emulsified aqueous or non-aqueous domain, containing at least one grease remover, wherein the two components are at least 1000 microns in size and are separate but separate domains from a single packaging means A two-component cleaning and degreaser liquid composition is provided that provides domains that can be distributed together.

The composition of the present invention is suitable for completely cleaning the skin. Degrease removers are included in the composition to remove grease, such as makeup, from the skin.

The invention also

i) dispensing the surfactant and the grease remover from the packaging means;

ii) applying a surfactant and a grease remover to the human body; And

iii) An improved method for removing grease from skin using the aforementioned cleansing and degreaser compositions comprising rinsing and removing the resulting mixture of grease and detergent with water.

The present invention also provides a packaged cleaning composition for topical use and use in another aspect. Packages suitable for use in this aspect of the invention are preferably multi-compartment packaging, such as two-compartment packaging.

An advantage of the present invention is that the grease can be better removed by the surfactant-containing aqueous liquid composition during use. In particular, by including a relatively small amount of the short-chain polyol grease remover in the surfactant-containing component of the two-component composition, it is possible to provide a composition which is excellent in removing makeup and does not have the disadvantages of the conventional two-component foam forming cleaning composition particularly related to composition stability. It turns out that.

It has also been found that the use of the preferred short-chain polyol grease remover for the first surfactant-containing component of the composition may be compatible with the preferred surfactants used in the composition, including alkyl polyglucosides, monoalkyl phosphates, and mixtures thereof. .

Without wishing to be bound by theory, it is believed that the grease remover contained in the second component of the composition disperses into relatively large droplets while rubbing the composition in use, and these droplets readily remove grease such as makeup from the skin. By appropriately selecting the amount of short-chain polyol incorporated in the short-chain polyol grease remover and the first surfactant-containing component of the composition (if the short-chain polyol grease remover contains a water immiscible component), an emulsifying technique may be used to prepare the initial composition. The need is eliminated. In addition, relatively large droplets of degreaser from the second component of the composition, which are formed in situ during rubbing of the composition and promoted by dispersing the degreaser phase as a single phase or domain, are more likely to remove grease than relatively smaller emulsion droplets. It is believed to be effective.

The delivery of the active agent to the makeup film locally at high concentrations can enhance makeum removal. Relatively large droplets decrease in size during use, but the rubbing behavior used during application will facilitate their dissolution as a dispersed phase on the aqueous surfactant of the composition.

The use of a relatively small amount of a particular type of degreaser on the surfactant will conventionally incorporate the degreaser into the surfactant-containing phase, including the stability of the first surfactant-containing component of the composition, while further increasing the makeup removal effect. It was found to eliminate the shortcomings that were thought to exist. In addition, the presence of the grease remover in the composition has been found to contribute positively to other properties of the first surfactant component of the composition, including physical stability and antimicrobial stability.

It is convenient for the domains of the composition according to the invention to take the form of stripes of the first and second component compositions, which are isolated from one another in a separate chamber before use of the first and second components of the composition. It can be conveniently co-extruded side by side (ie unmixed) from the two compartment package being stored.

The present invention provides the following additional benefits, which are not necessarily related to efficacy on their own, but more related to the problem of eliminating formulation instability and delivering other consumer benefits:

(a) By dividing the components into different domains, it is possible to avoid incompatibilities between formulation components that can cause instability and separation during storage.

(b) Two different structured systems can be used to provide optimal product viscosity, consumer feel and appearance for each domain, which can be applied more closely to the conditions of each domain.

(c) Two different conservation systems can be used for optimal stability for each domain, which can be applied more closely to the conditions of each domain.

(d) Similarly, two dye / pigment systems can be used for each domain, providing for example a consumer advantage that solidifies the idea that the product is an effective and true two-in-one product.

(e) Formulation components can be kept in separate domains until use, providing a consumer perceptible sensation such as exothermic, viscosity or change in appearance when they are formulated or reacted, especially with surfactant-containing components When the oil and grease remover-containing components are mixed, the blended composition may be diluted to improve the distribution of the composition on the skin and to improve grease removal.

(f) By retaining any UV light-sensitive material in only one chamber having UV filtration capability, it is possible to reduce costs for the amount of such UV filtration packaging.

(g) By using multi-chamber packaging rather than single-chamber packaging, the path length of light passing through the product can be reduced, thereby improving apparent transparency.

In a topical composition the first and second components of the composition are typically present in a volume ratio of 20:80 to 80:20, preferably 60:40 to 40:60 with one another. For simplicity of packaging arrangement, the topical composition is conveniently comprised of the first surfactant containing component and the second grease remover component in a volume ratio of 50:50 with each other.

In a preferred situation, a single packaging means may comprise a two compartment structure in which the aqueous surfactant and the grease remover are contained separately, although a larger number of compartments are possible, and a single compartment system may also be possible.

For example, in a single system, separate domains of the composition according to the invention can be realized in separate stripes of surfactant and scavenger or in systems in which droplets of one component (optionally in encapsulated form) are suspended in another. .

Another method of separating the surfactant and the remover is to use a single chamber by coextrusion or injection of separate domains of the composition such that the individual stripes or droplets produce a suspended droplet or stripe product containing the surfactant or remover. Charging in the pack.

The composition of the present invention may be formulated as a skin washing product, for example, a composition for washing or hand washing, for convenience, but may also be formulated as a bath or shower gel or hair washing product.

The compositions of the present invention may be generally pourable liquids or semi-liquids, such as gels or pastes.

The components of the topical composition are formulated to be suitable for packaging and dispensing from twin cylinder packs of the type generally described in the aforementioned US Pat. No. 5,020,694 or 4,964,539.

The compositions can be prepared by techniques generally known in the art. For example, for surfactant compositions, the components of the composition except silica, polyethylene powder, perfume and preservatives may be mixed together, then silica and polyethylene powder may be added and mixed under vacuum. Finally, perfume and preservatives are added and mixed. In the case of the second component, the acrylate copolymer can be dispersed in water under high shear and the oily remover and preservative can be added with stirring to form a uniform dispersion. The remaining ingredients can then be added with stirring under vacuum.

The components may then be filled in chambers of a two compartment package, which package distributes the two components of the composition in equal volumes.
