Definitions

• a process for preparing a composition comprising cat ionized starch and cationized polygalactomannan
• the present invention relates to a process for the preparation of a composition, characterized in that at least one starch and at least one polygalactomannan are cationized together.
• the present invention further relates to the compositions and preparations containing such compositions.
• the compositions of the invention are, in particular, personal care products, household care products, pet care products and preparations for treating yarns, fibers, textiles, including nonwovens, paper and board.
• the invention further relates to the use of the above-mentioned compositions.
• the surface properties of the skin and hair are of particular interest in cosmetics, and it has always been of interest to develop cosmetic compositions which moisturize and favorably affect the surface and the keratin scaffold. This often happens because the water absorption capacity of the upper skin and keratin layer is improved. Suitable substances for this purpose must have adhesive properties.
• Human and animal hairs consist of keratin, a sulfur-containing fibrillar protein with an isoelectric point between pH 3.2 and 4. Thus, the hair present in most care products has negative charge.
• Synthetic, cationic polymers for example, have long been used as such or as additives in conditioners and shampoos to improve the combability of wet or dry hair.
• the affinity of cationic polymers to negatively charged hair leads to a film formation, which hampers the knotting of the hair and reduces hair sticking by static charge when combing.
• polyacrylamide-based petrochemical Polyquaternium-7 which binds due to the high cationic activity color and dirt constituents from the wash liquor and especially on light laundry (eg towels) precipitated and discolored.
• 7 Contains, as an impurity, residual amounts of poisonous and contemplated acrylamide, not to speak of the environmentally harmful aspects
• the products according to the invention are based on natural substances, which signify a significant advantage.
• the film formation on the skin caused by cationic additives is used to fix active ingredients on the skin, to improve the sensory profile of the skin, to prevent the skin from drying out, and to add flavor to the skin through affinity place.
• cationic cassia flour The use of cationic cassia flour is relatively new. As an example, it is described in US patent application 7 923 422 from the year 2011 entitled “Cassia derivatives and application therefore.” This cationic cassia flour has recently become commercially available under the brand name SENSOMER from LUBRIZOL a powder product.
• cationic guar gum and cationic cassia flour a major disadvantage of cationic guar gum and cationic cassia flour is that the hair has a hard and inflexible feel, that is, it appears hard and stiff.
• the conditioning of hair with cationic guar gum or Cassiamehl alone produces a well-improved combing behavior, both wet and dry hair and also an antistatic effect.
• the achievable effects no longer meet the demands of the cosmetics industry in terms of wet and dry hair and their sensory properties.
• silicone oil, silicone products or other fatty substances in all of these guar and cassia formulations in order to counteract the roughness. Silicones (dimethicones) are but nowadays more and more undesirable, unfortunately, with these two basic substances unconditional condition to counteract the adverse effects.
• the novel compositions had to be compatible, clearly soluble with most of the cosmetic ingredients used, and easy to process. You should have the necessary properties with no or less addition of silicone compounds or fatty substances, in particular, they should give hair a softy handle, so the hair should have low stiffness and roughness. In addition, they should drastically reduce the material cost of the compositions over the prior art.
• Yarns, fibers, textiles, including nonwovens, paper and paperboard are said to impart desirable surface properties such as grease impermeability and the like to the compositions of this invention.
• novel compositions should be made available in a user-friendly liquid form as far as possible.
• the present invention relates to a process for the preparation of a composition, characterized in that at least one starch and at least one polygalactomannan are cationized together, wherein the feature according to which the cationization is carried out together is a particular feature of the process according to the invention.
• the fact that starch and polygalactomannan are collectively subjected to a cationization process results in a composition having completely new and improved properties which exhibit synergistic effects as compared to the separately cationized polymers.
