Abstract

Abstract: This invention relates to bars of soap containing 50-90% of a fatty acid soap, obtained from tallow (a non-lauric fat) and of 50-10% of a stearic acid soap, obtained from coconuts ( lauric fats). A known solution to the problem of harshness is to reduce the level of hardness. Existing soap and replacing the rest of the formula with so-called actives. One of the well-known problems that arise from the presence of the co-actives is the loss of product shape in the resulting soap bars. Therefore, soap bars that include active adjuvants must be made with a manufacturing process that increases the cost of the final products. The invention provides soap bars containing: a) at least 25% by weight of the total active substance of lauric acid soaps, b) as balance for soap, a non-lauric soap having an iodine value less than 45, c) at least 5% by weight of the total substance The active substance is composed of one or more synergistic mildness active substances. These briquettes have acceptable smoothness but can be made with conventional processing equipment.

Description

Z. I Bath soap molds Full description Background of the invention: The present invention relates to bath soap molds, especially soft plan soap molds; They include a mixture of soap with one or more active ingredients. For many years, soap bars were made from fats by converting triglyceride components into 0 (J) fats (fatty acids) and forming that soap into bars. ali: The most important fat that was used in the manufacture of soap was animal fat (palmatic/stearic fat extracted from animal products); and igh coconut oil (laurie fat) For the purposes of this description; the terms “Cu oil” and “fat” are interchangeable unless the context requires otherwise and other palmitic/stearic fats are known to be used 0 -_ Such as palm oil and Jie alternative lauric fats, palm kemel oil, babassu, or macauba. The least expensive Cis (Cig Al) (obtained from tallow and palm oil) provides structure to the final product of soap bars; prevents or delays the melting of the soap bar upon exposure to water. The more expensive yo; short chain From derivatives of lauric fat such as lauric acid and other types of melted soap (Ji) obtained from coconut oil and palm kernel oil (palm kerneldiadll), it gives foaming properties to all the composition. One of the general problems for forming soap bars is finding a balance Between cohesion: for structure (from cheap ingredients) and preservation of foaming properties (from more expensive ingredients) when calculating the total cost ee 7 The following is the distribution of the fatty acid chain length for a group of soap ingredients: 14Y

Saturation and not related to saturated fat. Thus saturated fats have an iodine value (IV) of iodine and have a low iodine value of 7000; And monounsaturated fats bind about a molecule and have a value of 77009 and correspondingly; Monounsaturated fats bind about .001 about ve gives an iodine value for beef tallow (CRC (CRC presses for VY booklet) and layer Yor iodine net of about 59.5; for walnut oil India Value of iodine in typical commercial formulations; bar soaps contain 70960-450 stearic acid soap of 790-01 stearic acid soap and non-lauric suet (i.e. animal fat)

¢ In typical commercial installations; Soap bars contain from 495-750 fatty acid soap obtained from animal tallow (i.e. non-lauric fat) and from 01-790 from fatty pasa soap obtained from coconuts (i.e. laurie fat) and in particular; In countries where tallow is acceptable to consumers, most commercial soap formulations include tallow 77856 and coconut oil 7270. In countries where tallow is not acceptable, Jad is replaced by other oils and fats such as palm oil. From International Patent No. 84 /049749 We realize that it is known to form soap bars; or soap blocks shaped into molds or frames; including alkali metal soaps or Cyr-Cyp (fatty acids) ,.-.,); _ polyhydric alcohols containing carbon atoms of .2,20

Polyhydric alcohols 0 and/or polyethylene glycols having a molecular weight of 600,000 are traditional additives to bath soap and water. These are molten forged from the components of the assembly which are poured into a molded bar or frame. a

Known solutions to the problem of roughness include reducing the amount of soap present and replacing the rest of the formula with so-called active substances

Yo Help 00-200765. A known problem arising from the presence of active J gall is the loss of product structure in the resulting bars of soap.

UK Patent Application No. 718774647 (Procter & Gamble) discloses a bath soap comprising a stearic acid soap; an adjuvant of a synthetic surfactant co-active and a water-soluble polymer. To reduce the softening effect : softening effect of the auxiliary active substance.” It is necessary to have some soap in the phase 0 called the beta-crystalline phase (Say beta-crystalline) to achieve crystallization in this phase only by using a high aki high shear strength (i.e. Energy working in an additional processing step after the drying step and before finishing. European Patent No. 777716 (Colgate) revealed the production of soap bars ples of soap and surface-active auxiliary materials treated with This ethoxylated soap formulation needs to be dried below the critical moisture content Zo critical by weight to harden 33 enough to process into a bar using conventional soap making and molding equipment This drying step requires additional equipment In the form of drying pans to be used prior to the final finishing of soap. combined from the beta-crystalline phase; Surface-active auxiliaries treated with ethoxylated non-ionic and water-soluble polymer. As stated above; Structural modifications require modification in the soap making line to give energetic working to form the beta-crystalline phase. It is clear from the foregoing that each of the known alternative processes for the production of soap bars that contain auxiliary active substances requires the provision of more Aallaall equipment, especially in the form of drying equipment form of: drying 0 and/or energetic working apparatus. The JA additional processing step equipment is used before the soap is finished. to use traditional soap production lines without substantial modification; There is a need for a bar soap formulation that avoids these extra steps and yet provides a product with a lower coarseness while retaining foaming and textural properties. General Description FAM Yo The present invention introduces this formulation and continues to use a highly saturated, long chain soap ¢ that is, a soap with a relatively less unsaturated long chain than traditional soap formulations. It is believed that the exclusion of non-lauric fatty acid soap

The preferred upper limit for laurie acid soap is 1 for economic reasons. : in preferred embodiments of the invention; The ded of iodine in 200-12101316 soap ranges from 01 to cto© and is most preferred between YO to fe and for traditional soap mixtures of tallow (coconut suds); The iodine value of non-lauric soap is calculated at 5/8 (similar to that of pure tallow); ade is shown to be the non-lauric fat of the formulation of the present invention; Pans are more saturated than those used in traditional soap making. While single oils and/or fatty acids derived from them may be used in the soap ingredients of the formulations; According to the invention; except that the use of mixtures or two or more oils and/or combinations of fatty acids; not ruled out; In practice, it is considered usual. And as mentioned by del in the formulations of the invention Mall, the percentage of saturated fatty acids was converted to unsaturated in non-lauric soap in favor of saturated fatty acids. This can be achieved by adding saturated materials to the soap mixture or removing unsaturated materials. In particular; It is preferable to achieve a relative vo increase in the rate of saturated substances by removing oleic soap, and oleic is soluble 1- and (oleic) soap _ and (C18:2 ((linoleic) in animal fat and JA oil and removing Such oils increase the overall .saturate content of soaps; the iodine value in the soap mixture will be less than YO taking into account both components .non-lauric lauric ;Y. in certain embodiments of the present invention; The formulations also include one synthetic anionic active on JWI at a rate not exceeding 771 by weight, preferably a rate not exceeding 0 by weight, and the absolute best is a rate not exceeding 77 by weight of the total active substance content of the product.
