Description

SOFT LIQUID SOAP FOR THE BODY FIELD OF THE INVENTION The present invention relates to a body-gentle liquid soap composition comprising a surfactant component comprising at least one non-ionic surfactant having a hydrophilic-lipophilic balance of about 1.5 to 13.0, at least one anionic surfactant, electrolyte; and wherein said surfactant component has an opaque structured domain.

BACKGROUND OF THE INVENTION Composition products for personal care such as liquid body soaps are becoming increasingly popular in the United States.

United and around the world. The compositions desired for body washing must meet a number of criteria. For example, to be acceptable to consumers, a liquid soap composition for the body must exhibit good cleaning properties, exhibit good foaming characteristics, be gentle to the skin (without drying or irritate the skin) and preferably also Provide a conditioning benefit to the skin. Compositions for washing the body that attempt to provide conditioning benefits are known. Many of these compositions are aqueous systems comprising an emulsifying conditioning oil or other similar materials in combination with a foaming surfactant. Although these products provide both conditioning and cleaning benefits, it is often difficult to formulate a product that deposits a sufficient amount of skin conditioning agents on it during use. To combat the emulsification of the skin conditioning agents by the cleansing surfactant, large amounts of the skin conditioning agent are added to the compositions. However, this introduces another problem associated with these cleaning products and conditioners. Raising the level of the skin conditioning agent to achieve better deposit negatively affects the foaming performance and stability of the product. Accordingly, the need persists for a stable composition of mild body soap that provides longer lasting cleaning of the foam and better foaming characteristics and benefits for the skin such as silky feel of the skin, better smooth feeling of the skin, and better smooth feeling of the skin. It is therefore an object of the present invention to provide a liquid soap composition for the body comprising surfactants having a structured phase which can be combined with high levels of skin conditioning materials which are emulsified in the composition and are preferably suspended from the skin. such that skin conditioning materials can be deposited at higher levels while at the same time maintaining superior performance against conventional liquid body soaps.

After centrifuging for 18 hours, determine the relative phase volume by measuring the height of each layer using an electronic digital gauge (within 0.01 mm). First, measure the height as Ha that includes all the materials in the ultracentrifuge tube. Second, measure the height of the beneficial component as Hb. Third, measure the structured surfactant layer as Hc. The beneficial component layer is determined by its low moisture content (less than 10% water as measured by Karl Fischer titration). It usually occurs at the top of the centrifuge tube. The total height of the surfactant layer (Hs) can be measured by means of this equation: Hs = Ha - H The components of the structured surfactant layer may comprise several layers or a single layer. After ultracentrifugation, there is generally an isotropic layer in the bottom or near the bottom of the ultracentrifuge tube. This clear isotropic layer usually represents the unstructured micellar surfactant layer. The layers above the isotropic layer generally comprise a higher concentration of surfactant with larger ordered structures (such as liquid crystals). These structured layers are often opaque to the naked eye, or translucent, or clear. There is usually a distinct phase boundary between the structured layer and the unstructured isotropic layer. The physical nature of the structured surfactant layers can be determined through light microscopy. Structured surfactant layers typically exhibit a distinctive texture under polarized light. Another method to characterize the structured surfactant layer is to use the X-ray diffraction technique. The structured surfactant layer exhibits multiple lines that are often associated mainly with the long spaces of the liquid crystal structure. Finally, the structured domain-volume relationship is calculated based on the following equation: Structured domain relationship - volume = Hc / Hs * 100% If there is no beneficial component layer present, use the total height as the height of the surfactant layer, Hs = Ha. Method of determining the yield point An AR2000 controlled stress rheometer from TA Instruments can be used to determine the yield point of the component. For the purposes of the present invention, the yield point of the surfactant component or the soft liquid soap composition for the body is the amount of effort required to produce the flow start, where a significant increase in the velocity of the tension occurs. The determination is made at 25 ° C with the measuring system of parallel plate 4 cm in diameter and 1 mm apart. The determination is made by means of the programmed application of a continuous increase of a cutting effort (normally from approximately 0.1 Pa to approximately 500 Pa) during a time interval of 5 minutes, collecting 30 data points per decade of effort in one effort progression evenly spaced. The stress results in a deformation of the sample, and a shear stress versus tension curve can be created. The shear stress (Pa) is plotted on a curve on the x axis versus the stress on the y axis using logarithmic scales for both axes. The composition of mild liquid soap for the body and the surfactant component that are structured exhibit an initial region at low stresses that appears as a straight line when drawn in this way. The yield point is the stress point at which the observed stress deviates by more than 10% from a regression line (ie from predicted stress) extended from the region of the initial straight line in the log-log plot , determined by the linear regression of the transformed log-log stretch-stress data between 0.2-2.0 Pa, and continues to deviate by an amount increasing and accelerating substantially with each subsequent point, so that the flow occurs. The surfactant component is measured before being combined in the composition, or after being combined in the composition by separating the compositions by suitable non-destructive physical separation means.

Density method (specific gravity) The metal pycnometer is used to determine the density (specific gravity) of both the cleansing phase and the beneficial phase compositions. A suggested type of metallic pycnometer can be obtained from Fisher, 3-347. Another equivalent pycnometer can also be used. The following procedure is the steps to measure the density (specific gravity) of the cleaning phase compositions and those of the beneficial phase. Step 1) Cleaning: The metal pycnometer should be clean and dry before use. Completely dismantle the metal pycnometer and wash all parts thoroughly with water. After rinsing with water, rinse with alcohol. Expel alcohol with a clean, dry air flow. Step 2) Standardization Fill the dry and clean pycnometer with distilled water at 25 ° C. Place the cap on the body of the pyknometer and screw the cap firmly into place. Dry the outer part of the pyknometer with a disposable tissue and weigh 0.001 g. Clean and dry the pyknometer according to the instructions above. Assemble and weigh the dry pycnometer at 0.001 g.

Water weight = Weight of the pycnometer and weight of water in the empty pycnometer- Step 3) Sample measurement Clean and dry the pyknometer according to the instructions shown above. Allow the sample to equilibrate at room temperature. Pour the sample into the pyknometer, taking care to avoid introducing air into the sample inside the pyknometer. Add an additional part of the sample so that it extends slightly above the top of the threads. Place the cap inside the cap and screw it firmly into the body of the pyknometer. Any additional amount of the sample will be forced through a hole in the cap of the pyknometer. Wipe off excess sample carefully using a disposable tissue. Weigh the filled pycnometer to 0.001 g.

Weight of the sample = Weight of the pyknometer and weight of the sample in the pyknometer.

Step 4) Specific gravity = Sample weight / Water weight The difference in density between the cleaning phase and the beneficial phase is less than 0.15 g / cm3, preferably the difference in density is less than 0.10 g / cm3, with greater preference less than 0.05g / cm3 and even more preferably less than 0.01 g / cm3.
