Description

Foam cosmetic composition for cleansing or removing makeup

Technical field

The present invention relates to a foam composition for topical application comprising a specific surfactant consisting of at least one partially or fully neutralized fatty acid, a non-betaine amphoteric cosurfactant and an anionic cosurfactant of the sulfosuccinate type It also relates to the application of the composition in the field of cosmetics or dermatology, especially as a cleansing and/or cleansing product for human stratum corneum substances, especially skin.

Cleansing the skin is very important for facials. Skin develops a blotchy appearance as residual fats such as excess sebum, residual daily makeup and makeup removers, especially waterproof products, can accumulate in skin wrinkles and clog skin pores.

Background technique

Several main types of skin cleansing products are known: aqueous foaming lotions and gels, cleansable anhydrous oils and gels and foaming emulsions.

Rinsable anhydrous oils and gels have cleansing activity due to the oil contained in them. These oils dissolve residual oil and disperse makeup pigments. These products are effective and well accepted. Their disadvantages are their high weight, lack of foam formation, and lack of cooling sensation in use, which are disadvantages from a cosmetic point of view.

Furthermore, foaming detergent aqueous emulsions and gels have cleaning activity due to the presence of surfactants that suspend residual oils and cosmetic pigments. They are effective and are a joy to use because of their lather and ease of removal. However, the lotion is too fluid and needs to be applied delicately, and it is difficult to form a thickened gel while maintaining good foaming properties.

To obtain a thick composition with good foaming properties requires the preparation of a foam emulsion.

As used herein, "foam emulsion" means a viscous, opaque composition, usually packaged in a tube, usually consisting of an aqueous medium, and other additives such as polymers, polyols and fillers, where the aqueous medium contains surface-active Agents such as fatty acid salts (soaps) or mixtures of anionic, nonionic or amphoteric synthetic surfactants.

These creams, specially formulated for cleansing the skin, are mixed with water to create a lather. They can be used in two ways:

One is to apply the emulsion on water, apply it to the face or body, and then rub it directly on the face or body in the presence of water to produce a foam;

·The second is to form a foam in the palm of your hand first, and then apply it to the face or body.

The foam formed by these two methods should be cleaned and removed.

Among the currently commercially available foam emulsion products, the foaming properties of some products are not satisfactory, especially in terms of rapid foaming, foaming power and emulsifying properties (density) of the foam.

Other foam emulsions are less stable and are more susceptible to changes in temperature and transport and storage conditions: these changes can lead to relatively rapid macroscopic separation of the formulation, causing the system to separate into at least two phases.

However, it is necessary for cleansing foam emulsions to be stored for several months at different temperatures and under different shipping conditions. Indeed, during the shelf life of the product, the product is exposed to varying temperatures due to different climatic conditions, storage or transport conditions. Products are also shaken in transit. There is also a need for these foam emulsions to be able to be used in hot countries without transport and storage problems.

There is also a need for these cleansing foam emulsions to be able to be stored under adverse conditions at different temperatures and shipping conditions not listed above.

Contents of the invention
