Description

The present invention relates to an impregnating liquid containing certain skin care and cleansing agents and particulate wax for application to cosmetics, in particular cosmetic wipes having a special structure.

Cosmetic wipes are gaining in importance because they conveniently and hygienically satisfy modern personal care needs. Two forms of cosmetic wipes are already commercially available from several manufacturers: wet wipes made of textiles or tissue paper impregnated with cleansing or skin care preparations, It is a dry wipe that needs to be wetted before. Numerous patent applications describe cleansing cloths that are soaked in various textiles. While the cleansing function was the primary focus of the first commercially available cosmetic wipes, the focus is now on skincare. For example, International Patent Application WO 95/35411 proposes wet wipes impregnated with lotions containing fatty acid esters, fatty alcohol ethoxylates and fatty alcohols in addition to mineral oil. With respect to cosmetic dry wipes, particular mention is made of International Patent Applications WO99/13861 and WO01/08657. In those cases, nonwoven, generally unstructured textiles are impregnated and/or coated with formulations containing surfactants and skin care additives and then optionally dried. Depending on the size of the substrate, the wipes can be non-reusable impregnated wash cloths or relatively small cleansing pads. Consumer demand for cleansing performance, in-use and after-use skin feel, and ease of use are thus technical challenges for developers. Thus, the amount of lather produced after wetting or in the wet wipe itself, lather stability and lather structure greatly influences the sensory impression during and after cleansing. Obtaining a good lather structure and a sufficient amount of lather after wetting is difficult unless the cloth/wipe is strongly mechanically rubbed by hand. This problem can be exacerbated by other non-surfactant skin care additives.

It is an object of the present invention to provide impregnating formulations for wet and dry cosmetic wipes with improved cleansing, skin care and sensory performance for cleansing and caring for the hair and body. The formulations according to the invention exhibit, inter alia, a deep cleansing effect on the pores and, due to the optimal foaming properties of the formulations, provide a pleasant skin feel during and after use.

The present invention is an impregnating formulation for cosmetic wipes, comprising:
(a) an emulsifier mixture containing a nonionic surfactant and an amphoteric surfactant in a quantitative ratio of 10:1 to 1:1 relative to the amount of emulsifier,
(b) wax component mixtures containing wax esters, partial glycerides and fatty alcohol ethoxylates; and (c) formulations containing at least one cationic polymer.

It has been found that formulations of the above composition on the structured surface of substrates (cosmetic wipes) provide advantageous foaming properties, good cleansing effect and pleasant skin feel. By combining a substrate with an impregnating liquid containing a fine dispersion of particulate "care" waxes having a certain particle size, mild mechanical action can rapidly generate an abundance of fine bubbles. In this regard, wax component compositions containing wax esters, partial glycerides and fatty alcohol ethoxylates are particularly effective, and emulsifier mixtures of nonionic and amphoteric surfactants in a quantitative ratio of 10:1 to 1:1 are particularly effective. It turned out to be An impregnating liquid of this composition provided a particularly good skin feel during and after use of the cosmetic wipes impregnated with it. In addition, the wax particle size influences the lather properties and the skin feel during and after cleansing. The smaller the particle size, the better the sensory impression.

Substrate The impregnating liquid of the present invention is suitable for application to wet cosmetic wipes and is preferably used for dry cosmetic wipes.

However, the fabric may also be glove-like, in which case it may have a multi-layered structure (the fabric layers inside the glove are more hydrophobic and have a barrier function, preventing the hands from coming into contact with the formulation or moisture). to protect from).

The base fabric of the cosmetic wipes of the present invention has a uniformly structured surface with circular to elliptical depressions due to its manufacturing method (hydroentanglement using a hydroentanglement belt). Such depressions (also called pits) are circular or elliptical, with a diameter or width of 0.1-1 mm, preferably 0.2-0.6 mm, and a diameter or length of 0.5-5 mm. 0 mm, preferably 0.8 to 1.5 mm.

Particle Size of Wax Dispersions, and Particle Size Measurement The particle size of wax dispersions used in impregnation and coating fluids greatly affects the sensory properties and foaming and cleansing performance of wipes. To achieve optimum performance, the average particle size of the dispersion should be up to 13 μm, preferably up to 4 μm, more preferably up to 2 μm. For this purpose, the usual dispersion preparation methods known to the person skilled in the art are chosen. Thus, for example, the particle size can be adjusted by subjecting the dispersion to varying loads in a high pressure homogenizer.

However, depending on the wax component selected and possibly other auxiliaries, the wax dispersion must be adapted to the conditions for adjusting the average particle size. The wax component selected is from 55 to 50%, as it is assumed that a decrease in particle size usually accompanies an increase in temperature of the medium, allowing further processing of the wax dispersion to occur without a change in particle size. It should have a melting point or melting temperature range of 90°C.

Particle size was measured using a Coulter LS230 laser particle analyzer from Beckman Coulter. This instrument uses the PIDS (Polarized Scattering Intensity Difference) method in addition to conventional laser diffraction to extend the measurement range down to the submicron range. The laser emits light with a wavelength of 750 nm, to which are added wavelengths of 450, 600 and 900 nm according to the PIDS method. The 132 detectors are combined to give a total measuring range of 0.04-2000 μm (divided into 116 size groups). Evaluation is performed by software based on Frauenhofer's diffraction theory or Mie's scattered light theory.

The measurement sample is diluted by a factor of 100 by the sample feed module. Deionized water is used as the dispersing medium. The sample feed module ensures continuous circulation of the dispersed sample through the measurement cell. Circulating samples were sonicated for 30 seconds before starting the actual measurement. This was done with a Beckman Coulter ultrasound module connected to an analyzer. The evaluation was performed exclusively according to Mie's scattered light theory, using a refractive index of 1.47 for the dispersed medium. The stated average particle size is based on the _D50 value of the volume distribution.

An impregnating liquid containing a dispersion of finely dispersed caring particulate wax having a certain particle size is applied to the structured fabric. This is done so that, optionally after subsequent drying (by hot air drying, vacuum drying or roller drying), the dispersion loosely adheres to the substrate as a discontinuous layer. The temperature during the drying process is adjusted so that the wax component particles avoid fusing with the fabric and can be finely dispersed in the foam created by the wetting and mechanical action of the cloth. It should be chosen to be below the melting point of the component. This also makes it a requirement that the indentation of the fabric and the particle size of the wax component particles correspond to each other. The pits in the fabric should be smaller or significantly larger than the dispersed and then applied wax component particles. Otherwise, it is difficult to ensure easy dispersion of the particles during foaming.

The impregnated and dried cosmetic wipes produced are dry to the touch. The residual water content after drying, or the water content of the dry cosmetic wipes, is according to the invention 0.1 to 4 wt. Preferably it is 0.8 to 2% by weight.
