Description

COSMETIC METHOD TECHNICAL FIELD The present invention relates to a cosmetic method. In particular, the present invention relates to a cosmetic method for treating the skin, which provides good moisturization, hydration, skin feeling, skin smoothness and / or smoothness of the skin.

BACKGROUND OF THE INVENTION The skin is made up of several layers of cells that cover and protect the keratin and the fibrous proteins of collagen that form the framework of its structure. The outermost part of these layers is called the stratum corn e um, it is known that it is composed of sets of 25nm proteins surrounded by 8nm thick layers. Anionic surfactants and organic solvents normally penetrate the membrane of the stratum corn eum and, by delipidization (ie, elimination of lipids from the stratum corn eum), destroy its integrity. This destruction of the topography of the surface of the skin leads to a rough feeling and eventually allow the surfactant or »« * ^ * - ^^^^ nar ^ afliBifli solvent interact with keratin, creating irritation. It has been recognized that maintaining the adequate aqueous gradient across the stratum corneum is important for its functionality. Most of this water, which is sometimes considered to be the plasticizer of the stratum corneum, comes from within the body. If the humidity is too low, such as in a cold climate, There remains an insufficient water content in the outer layers of the stratum corneum to adequately laminate the tissue, and the skin begins to flake and burn. The permeability of the skin also decreases somewhat when there is an amount 15 inadequate through the stratum corneum. On the other hand, too much water on the outer part of the skin causes the stratum corneum to finally absorb three to five times its weight of bound water. This swells and wrinkles the skin and gives 20 result in approximately a two to three fold increase in skin permeability to water and other polar molecules. In this way, there is a need for a method that helps the stratum corneum maintain its 25 barrier and its water retention functions in its Oéí? Jh ?. optimal performance despite the harmful interactions that the skin can find in washing, work and recreation. In methods for treating the skin of the past, compositions comprising one or more "skin-friendly agents" have often been used. These skin-friendly agents are often soluble in water. For example, one way of providing high moisture to the skin is to incorporate polyhydric alcohol-like humectant materials such as glycerin in the composition. Compositions for the skin with high levels of wetting, however, are often perceived by the consumer as uncomfortable as the compositions may have a sticky or viscous feel when applied to the skin. There seems to be a direct relationship between the amount of the agent suitable for the skin and the effectiveness of the composition in providing the benefits for the skin. However, it is also the case that the higher the level of agent suitable for the skin, the greater the risk of the associated negative effects. One way to alleviate this problem is to rinse the skin with water. However, this ¿^ ^ ¿^ ^ ^ ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡ zt ^ «s? ak ^^ rinsing the skin will also make the agent suitable for the skin go with the washing in particular if the suitable agent for the skin is soluble in water. It is also known that quaternary ammonium agents are used in cosmetic compositions. See, for example, WO-A-99/27904, WO-A-96/32089, and EP-A-789, 076. Also, US-A-5, 804, 205 disclosing skin care compositions. which are claimed to provide a high degree of wetting without leaving a "viscous" or "sticky" residue. The compositions contain quaternary ammonium compounds having two alkyl groups of 16 to 22 carbon atoms, moisturizing and non-irritating hydrophobic micro spheres having an average particle size of less than 50 μm. It is claimed that polymer hydrophobic micro spheres significantly reduce the "stickiness" associated with high levels of humectant. A method for treating the skin with these compositions is also disclosed in US-A-5, 804, 205. However, the quaternary ammonium agents commonly used in the prior art are often not biodegradable i. Ajizal *, &;., ^ * T «A - tfirittrr-? - - i? IFf1i? 'iliCiL__j easily and therefore can be harmful to the environment. Unexpectedly it has been found that cosmetic methods comprising treating the skin with compositions comprising at least one quaternary ammonium agent and a humectant and then rinsing the skin provide benefits such as good wetting, moisturizing, skin feeling, softness of the skin and smoothness of the skin, although they show low levels of negative effects such as greasy, viscous or sticky character. While not wishing to be bound by the theory, it is believed that in the composition used in the present method, the quaternary ammonium agents of the present invention can form vesicles of the humectants and promote their deposition on the skin. This results in a smooth and even application of the humectant to the skin with minimal viscous / sticky / fatty character. It is believed that rinsing further reduces the negative effects by washing away excess humectant which causes a viscous or greasy feeling to the skin. Prior art methods comprising a rinsing step could often remove by washing too much of the agent suitable for the skin. With t the present method, however, it is believed that the quaternary ammonium agents retard the loss of the agent suitable for the skin by helping to mitigate the usual negative effect. Even when the 5 compositions used in the methods herein comprise extremely high percentages of humectant, for example 30% by weight, there are only low levels of the usual negative effects. It is also believed that ammonium agents 10 Quaternary helps reduce the loss of skin moisturizers due to environmental factors such as, for example, the water in the rinse step or abrasion of clothing or during washing. In addition, it is believed that quaternary ammonium agents 15 in themselves provide skin care benefits, such as good wetting, good skin feeling, good skin smoothness.
