Problems solved by technology

However, the quaternary ammonium ingredients conventionally used in the prior art are generally not readily biodegradable and are therefore harmful to the environment
[0006] It has now been surprisingly found that compositions comprising at least one readily biodegradable quaternary ammonium ingredient and at least 5% by weight of a humectant bring benefits associated therewith such as high skin feel, skin softness and skin smoothness, but show Associated adverse effects such as low greasiness, stickiness or stickiness

Abstract

The present invention provides a cosmetic composition comprising: (a) at least one readily biodegradable quaternary ammonium ingredient; and (b) at least 5% by weight of a moisturizer. The composition of the present invention brings good skin care benefits, such as good moisturization, good hydration, good skin feel, good skin softness and / or good skin smoothness, negative effects such as greasiness , low stickiness or stickiness. In addition, these compositions, once used, tend to degrade and are therefore gentler on the environment.

Description

technical field [0001] The present invention relates to cosmetic compositions. In particular, the present invention relates to cosmetic compositions that provide good moisturization, hydration, skin feel, skin softness and / or skin smoothness benefits. Background of the invention [0002] The skin is made up of several layers of cells that cover and protect the keratin and collagen fibers that form the structural backbone of the skin. The outermost of these layers is called the stratum corneum and is known to consist of 25nm protein bundles surrounded by an 8nm thick layer. Anionic surfactants and organic solvents generally penetrate the stratum corneum membrane and disrupt the integrity of the skin by degreasing (ie, removing lipids from the stratum corneum). This disruption of the topographical structure of the skin surface results in roughness, which ultimately leads to irritation by the interaction of surfactants and solvents with keratin. Many ...
