Description

COMPOSITIONS FOR PERSONAL CLEANING BACKGROUND OF THE INVENTION Technical Field The present invention relates to compositions for cleaning. In particular, it relates to foam-cleaning personal cleansing compositions suitable for simultaneously cleaning and conditioning the skin and / or hair and which can be used, for example, in the form of preparations for the foam bath, products for the shower, cleansers of the skin, hands, face and body, shampoos, etc. BACKGROUND OF THE INVENTION Foaming cosmetic compositions must satisfy a number of criteria, including the cleaning power, foaming properties and softness / low irritation with respect to the skin, hair and ocular mucosa. . The skin is made up of several layers of cells, which cover and protect the keratin and fibrous proteins of collagen, which form the outline of its structure. It is known that the outermost part of said layers, which we refer to with the stratum corneum, is composed of bundles of 250A proteins, surrounded by thin layers of 80A. Similarly, the hair has a protective outer covering, which is called a cuticle, which protects the hair's fiber. Anionic surfactants can penetrate the membrane of the stratum corneum and the cuticle and, through dyslipidation, destroy the integrity of the membrane. This interference with the protective membranes of the skin and hair can lead to the sensation of harshness on the skin and irritation of the eyes, and may eventually allow the surfactants to interact with keratin and hair proteins, causing irritation and loss of the protective barrier, and water retention functions. The ideal cosmetic cleaners, should clean generously, without removing the natural fat and / or dry hair and skin, and without irritating the ocular mucosa, or leave the skin restirada after using them frequently. Most of the soaps that generate froth, product s for the shower and tub bath, shampoos and soap bars, have this consequence. It is known that certain synthetic surfactants are mild. However, the main drawback of most soft synthetic surfactant systems prepared for personal cleansing products and shampoos, have low foam generation, when compared with shampoos and soap bars with the highest quality standards. Therefore, surfactants that are among the mildest, such as sodium lauryl glyceryl ether (SFA) f sulfonate have little foam generation. On the other hand, the use of highly foaming anionic surfactants with known foam generation propellants can produce an acceptable quality and volume of foam, but at the expense of the clinical smoothness of the skin. These two factors make the selection of the surfactant, and the formulation to obtain the benefits of softness and good generation of foam, a delicate balancing process.

In spite of the many years of research that the toilet industry has employed in personal cleansing, the vast majority of consumers remain dissatisfied with the softness of cleaning compositions of current products, finding, for example, that they have to be applied separately, a cosmetic lotion or moisturizing cream on the skin, after using a preparation for the shower or bath tub, in order to preserve the flexibility and hydration of the skin and to counteract the delipidating effect of the cleanser. So there is a need for personal cleansing products that provide a level of performance in the conditioning of the skin, in products for washing and rinsing, which previously, whose performance, had only provided a separate cosmetic moisturizer, applied after of the Clean, which does not dehydrate the skin or as a result the loss of the skin's flexibility, generating said product a foam which is abundant, stable and of high quality, which is a cleanser for the effective hair and skin, and which It has the characteristics of being able to rinse it easily, and that at the same time, has the characteristics of viscosity and a stable product and that it remains completely stable in the long term and under the conditions of extreme temperatures in storage.
