Abstract
The present invention provides a cosmetic composition comprising: (a) at least one quaternaryammonium ingredient; and (b) at least one sunscreen active. The compositions of the present invention provide sun protection benefits while having low tack or stickiness. Moreover, the composition of the present invention can bring about good skin care effects, and a low degree of adverse effects such as oiliness, stickiness or stickiness.
Description
technical field [0001] The present invention relates to a cosmetic composition. In particular, the present invention relates to a cosmetic composition that provides good moisturization, hydration, skin feel, skin softness and / or skin smoothness benefits and protects the skin from UV rays. Background technique [0002] The skin is made up of several layers of cells that cover and protect the keratin and collagen fibers that form the backbone of the skin structure. The outermost of these celllayers, called the stratum corneum, is known to consist of 25nm protein bundles surrounded by an 8nm thick cell 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 eventually leads to the interaction of surfactants or solvent...
