Description

Cosmetic composition

Technical field

The present invention relates to cosmetic composition.The present invention be more particularly directed to have the cosmetic composition that highly moistens effect and do not have obvious sticky sense.Said composition also has and easily is rubbed into characteristic and absorption characteristic in the good use, and excellent skin usability, skin softness and skin smooth effect.

Background technology

Skin is by the several layers cellularity, and these cells cover and protect keratin and the collagen fiber albumen that forms the skin texture skeleton.The outermost layer of these cellular layers is called horny layer, by the albumen Shu Zucheng of 25nm, is the thick cellular layer of 8nm around it.Anion surfactant and organic solvent generally can permeate as horny layer, and by degreasing (promptly removing lipid from horny layer), destroy its globality.Thisly can cause harsh feeling, and can finally make surfactant and solvent and horny layer interact, produce stimulation the destruction on the anatomy meaning of skin surface.

Recognize that at present the normal moisture gradient that keeps in the horny layer is very important for cuticular function.As most of water of horny layer flexibility agent from body interior.If humidity is low excessively, as in cold snap, the outer layer of stratum corneum moisture deficit is organized when pliable and tough with normal order, and skin can begin decortication and scratchy.When moisture when not enough in the horny layer, the permeability of skin also can decrease to some degree, and on the other hand, skin outside excess moisture can make horny layer finally absorb the 3-5 bound water doubly of himself weight.This can cause skin swelling and wrinkling, causes skin that the permeability of water and other polar molecules is increased about 2-3 doubly.

Therefore, although need skin in a kind of cleaning, work and the amusement process may run into detrimental effect but still help horny layer isolation features and water retaining function are remained on the compositions of optimum state.

The ideal characterisitics of cosmetics cream frost and emulsion is good skin sense, water-retaining property, moistness, absorbability and easily is rubbed into characteristic.The user is relevant with the emollient in the compositions to the skin sense of compositions such as skin softness or slickness, and it can be filmed or coating by coated formation on skin.The absorbability of compositions is with easily being rubbed into property is relevant with its physical behavio(u)r under mechanical stress, and these behaviors are subjected to the influence of the rheological properties of compositions.Known many cosmetics cream frosts and emulsion compositions can provide in various degree skin moistening, isolation and water conservation (moistening) effect.For the effect of moistening is provided to skin highly, need in compositions, add polyalcohols preserve moisture composition such as glycerol.The skin care compositions that contains big weight polyalcohol has the effect of highly moistening, but the user can not feel well, because can form very sticky coating when being coated in this based composition on the skin.

Therefore, still need to have the compositions of hanging down sticky property or viscosity, height moistness and excellent skin sense, skin softness and skin smoothness can be provided simultaneously.

Contain polymer film-forming agent in the disclosed compositions of WO97/27838, polyquaternary ammonium salt-10 for example, hydroxy acid, physics remover and carrier, said composition is used to improve the slickness of skin.In the compositions of hydroxyl-containing acid, add polymer film-forming agent, it is said unexpectedly to make resulting composition have the effect of the skin smoothness of increase.

Polymer film-forming agent such as polyquaternary ammonium salt-10 is described to the skin sense and improves chemical compound in US-A-5103763, use it in the skin care compositions, and this compounds can be by eccysis when cleaning skin.Embodiment has described the compositions that contains 4% glycerol and 0.2% polyquaternary ammonium salt-10.Also can contain the emollient shared in the said composition with cationic surfactant.In addition, US-A-4 has described in 938,951 and has contained volatile solvent, polymer film-forming agent and part composition of active components.Said composition it is said and can strengthen local substantial activity with active component that specifically, polymer film-forming agent can strengthen local substantial activity with active component.

The personal cleaning compositions that contains water solublity polyhydric alcohol such as glycerol and cation film forming polymer such as polyquaternary ammonium salt-10 for example is found in WO96/17917 and WO96/17916.But also contain anion surfactant or amphoteric surfactant in these compositionss, as eccysis formula product more than or equal to 4%.

Be surprised to find that at present,, can make the sticky property of said composition or viscosity reduce by in containing the leave-on cosmetic compositions of effective dose polyhydric alcohol, adding the polymer of cation.Said composition also has good absorbability, isolation and water retention characteristic except that the moisturizing properties with good skin sense, skin softness and slickness and excellence.

Summary of the invention

One aspect of the present invention provides a kind of leave-on cosmetic compositions that is suitable for being applied topically to skin, wherein contains:
