Description

The present invention relates to transparent and translucent molds for individual cleaning. These moldings are gentle, lightly lubricated and have good foaming properties.

These moldings also have the desired hardness properties.

Transparent personal cleaning molds are well known in the art and are demanded by many consumers. Unfortunately, the problem with shaping translucent personal cleansing molds is that they are either too rough as molded with large amounts of soap or may be undesirably soft. U.S.P. For example, U.S. Patent No. 5,041,234 (Instone et al.) Discloses a translucent mold containing more than 40 parts of soap (high soap content).

Like other "high soap translucent moldings," the molds reported by Instone et al. Have good foaming, low lubrication and hardness. However, such high soap translucent moldings are quite rough for the skin. Another disadvantage of such moldings is that their treatment generally requires the use of undesirable solvents, such as volatile short-chain monovalent alcohols, or special grinding to ensure transparency.

Transparent molds of lower soap content are known in the art. Transparent molds with less soap content contain less than 40 parts soap. U.S.P. U.S. Patent No. 5,002,685 to Chambers and Instone discloses an opaque mold made of 25-34% soap, 5-15% monovalent alcohol, 15-30% sugar and / or cyclic polyol and 15-30% water. However, the soap mixture according to Chambers et al. Consists of 18-26% soluble soaps and 8-16% insoluble soaps. The translucent mold according to Chambers et al. Is thus mainly made with soluble soap. Unfortunately, individual cleaning molds made with less than 50% insoluble soap (i.e., more than 50% soluble soap) can be unacceptably soft.

However, Chambers really opposes the use of large amounts of insoluble soap. In particular, Chambers et al. Report that the molds of Examples 37 and 38, which contain "30 to 20 weight percent insoluble soaps and 10 weight percent or less soluble soaps, have poor user properties due to their low soluble soap content.

(Autumn 8, 1-3). Treatment of this mold according to Chambers et al. Also requires the use of a volatile monovalent alcohol solvent.

U.S. Pat. No. 4,165,293 (Gordon) also discloses individual cleansing molds in which the soap component contains less than 50% insoluble soap. Typically, Gordon discloses a process for making a monovalent alcohol-free, "mainly ... tallow soap bar". It should be noted here that "tallow soap typically consists of about 51% by weight soluble soap and is thus mainly characterized as soluble soap. The translucent soap bar disclosed by Gordon further preferably comprises a mixture of 80-90% tallow soap and 10-20% coconut soap.

Within such a translucent mold, the soap component may contain 55-59% soluble soap.

U.S. Patent Nos. 5,264,144 (Moroney et al.) And 5,340,492 (Kacher et al.) Disclose a fatty acid soap (containing both soluble and insoluble soaps), water and synthetic (i.e., anionic, amphoteric and nonionic surfactants are disclosed. However, the cleaning molds described by Moroney et al., Are opaque and a

The cleaning molds described by Kacher et al. Are not necessarily translucent. Furthermore, none of the references discloses the production of a translucent cleaning mold.

It has now been found that individual cleansing molds containing 18 to 35 parts soap, in which the soap contains at least 50% insoluble soap, are transparent and exhibit the required hardness properties. These individual cleansing molds are gentle to the skin, lightly lubricated and have good foaming properties. Furthermore, the use of monohydric alcohols is not required for the production of these translucent moldings.

FIELD OF THE INVENTION The present invention relates to translucent, molded individual cleaning molds having desirable hardness properties. These translucent moldings are gentle, lightly lubricated and exhibit good foaming properties. Transparent moldings according to the invention include: 18-35 parts soap, wherein said soap comprises at least 50% insoluble sodium soap; 14 to 32 parts water; 5-37 parts of a foaming synthetic surfactant, wherein the foaming synthetic surfactant is disclosed

For the purposes of the present invention, a mold is considered to be translucent when a 14-point font is read through a 0.635 cm (1/4 inch) die thickness. If the 14-point font is not readable over a 1/4 inch (0.635 cm) font, the font is not translucent. See Gordon; U.S. Patent 4,165,293, which is incorporated herein by reference.

As used herein, the term "insoluble soap" refers to a sodium fatty acid soap which is less soluble than sodium myristate.

• · ·

The translucent mold of the present invention is preferably prepared without the use of monohydric alcohols. As a result, the translucent moldings of the present invention are very stable in weight. The production of non-alcoholic molds is also more economical. Some volatile monovalent alcohols (e.g. ethanol, propanol, butanol) may be used. However, the preferred moldings according to the invention are substantially free of monohydric alcohols. Caution is advised when using monohydric alcohol solvents because of their explosive nature.

Unless otherwise specified, the amounts, parts, percentages herein are by weight. It is noted that the term "soap blends" is expressed as a percentage by weight of soap (w / w). On the other hand, the term "parts" is used herein to refer to the weight of the finished part. All number ranges, ranges, ratios, etc. unless otherwise stated.

The individual components of the individual cleaning molds of the present invention and specific ways of combining these components in a desirable manner are described in detail below.

SOAP: The translucent mold comprises about 18 to 35 parts, preferably about 20 to 32 parts, more preferably about 24 to 32 parts soap. Surprisingly, soap quantities above about 35 parts cannot produce a translucent mold, and soap quantities below about 18 parts are unacceptably soft.

The soap blend of the present invention comprises at least 50% insoluble soap, preferably 50 to about 87% insoluble soap,

more preferably about 53-72% insoluble soap. Translucent moldings in which the soap component contains less than 50% insoluble soap are undesirably soft.

The term "insoluble soap" is defined herein as a fatty acid sodium soap which is less soluble in sodium myristate as described above. The term "insoluble soap" refers to monovalent salts of saturated fatty monocarboxylic acids having a chain length of 16 to 24, preferably 18 to 24 carbon atoms. These monovalent salts are normally sodium salts, although some other cations such as potassium, magnesium or alkanol ammonium ions may also be used. The preferred insoluble fatty acid soap is selected from the group consisting of sodium palmitate and sodium stearate and mixtures thereof. Other insoluble soaps, typically longer chain fatty acid insoluble soaps, may also be used.

The remainder of the soap mixture is soluble soap. The term "soluble soap" refers to monovalent salts of saturated fatty monocarboxylic acids of 8 to 14 carbon atoms and, in addition, monovalent salts of polyunsaturated fatty acids of oleic acid and 8 to 22 carbon atoms of chain length. Sodium myristate is defined as "soluble soap. Preferred soluble soaps are selected from the group consisting of myristic acid, oleic acid and lauric acid soaps and mixtures thereof.

The fatty acids used in the translucent moldings of the present invention are either soaps using either pure fatty acids, mono-, di- or triglycerides, or conventional fatty acids and oils.

can be prepared using appropriate amounts and ratios of coconut, palm oil stearin, tallow and triple-pressed stearin.

The term "coconut" as used herein for soap or fatty acid mixture corresponds to approximately the following carbon chain length distribution: 8% C8, 7% C10, 48% C12, 17.5% C14, 9% C16, 2 % C 18, 6% oil and 2.5% linolen. Coconut soap thus contains about 11% insoluble soap and 89% soluble soap.

The term "babassu" with respect to soap or fatty acid mixtures is defined herein as being approximately 6% C8, 3% C10, 46% C12, 20% C14, 7% C16 and 18% C18: 1. corresponds to materials with carbon chain length distribution. Babassu soap thus contains about 7% insoluble soap and 93% soluble soap.

The term "triple-pressed stearin" is defined herein as being approximately 5% myristic acid (C 14), 50% palmitic acid (C 16), and 45% stearic acid (C 18) with chain length fatty acids. The triple-pressed stearin soap thus contains about 95% insoluble soap and 5% soluble soap.

The term "hardened tallow" is defined herein as being approximately 3% myristic acid (C14), 50% palmitic acid (C16), and 45% stearic acid (C18). • · ·································································································································································································································································ededed it found it possible to found that it was a fatty acid substance with 2% oil acid carbon chain length The hardened tallow soap thus contains about 95% insoluble soap and 5% soluble soap.

By comparison, "tallow" is defined as a soap mixture (normalized mid-range values from Table 6.34 - Bailey; Industrial Oil and Timber Products, Volume 1, Wiley Intersciences) which is about 4% C14, 29% C16, 20% 18. a mixture of carbon atoms, 2% palmitic oil, 42% oil and 3% linolenic chain length soaps. The tallow soap thus contains about 49% insoluble soap and 51% soluble soap.

The amount of free fatty acid incorporated into the finished molds according to the invention is typically in the range of 0.5 to 3 parts, more typically 1-2 parts. However, there is no need for free fatty acids.

Preferably, the free fatty acid component is incorporated into the soap mixtures of the invention by adding free fatty acid to the soap mixture after saponification of the soap mixture. The free fatty acid component may also be included as a mixture of soap and free fatty acid, such as a mixture of acid-reactive soap and free fatty acid produced by over-neutralization in the soap making process.

The fatty acid soap according to the invention contains sodium soaps. However, small amounts of non-sodium soaps such as potassium, magnesium and / or triethanolammonium (TEA) soaps are also permitted. If such non-sodium soaps are used, they will preferably be employed in an amount of 0 to 5 parts by weight, preferably 10 to 5 parts by weight of the mold. .

WATER: The amount of water in the mold is about 14 to 32 parts, preferably about 18 to 27 parts, more preferably about 2226 parts. Within these preferred ranges, larger amounts of water are more advantageous for easier handling, mold integrity and other benefits.

The amount of water within the individual cleaning molds of the present invention is critical to obtaining a translucent mold with the desired hardness properties. If the water is less than about 14 parts by weight of the mold, the mold may not be translucent. If the amount of water present in the mold exceeds about 32% by weight of the mold, the mold may be unacceptably soft.

SURFACTANT: The amount of foaming synthetic surfactant in the mold is in the range of about 5 to about 37 parts, preferably about 10 to about 28 parts, more preferably about 12 to about 22 parts by weight. Synthetic surfactant is needed to improve the properties of the mold. Some of these properties are: foaming / foaming properties, mold tenderness, mold rinsing sensation, and lubrication / hardness properties.

The molded preparation is an anionic surfactant; nonionic surfactants; zwitterionic surfactants; It comprises a foaming synthetic surfactant selected from the group consisting of amphoteric surfactants and mixtures thereof. The foaming surfactant is defined herein as a synthetic surfactant or a mixture of surfactants that is measured at 25 ° C (-2C) at 1 to 5 at CMC (critical micelle concentration). · 10 N / m (10-50 dyn / cm), more preferably -2

- Equilibrium surface tension of 4.5 to 10 N / m (20-45 dyn / cm). Some surfactant mixtures have a lower surface tension than some of its components. Thus, both low and high foaming surfactants which are highly and slightly soluble in water can be used in the formulations of the invention. Particularly claimed are foam-enhancing synthetic detergent surfactants and / or synthetic detergent surfactants known as good dispersants for hard water soap bars.

A preferred selected foaming synthetic surfactant may comprise a mixture of anionic and zwitterionic / amphoteric surfactants. The addition of zwitterionic / amphoteric surfactants allows to increase the mildness and foaming properties. However, this addition may lead to a deterioration of the structure-forming properties of the mold, such that the amount of amphoteric surfactant must be kept below 10 parts. Preferred zwitterionic / amphoteric surfactants are selected from alkylammono-mono and diacetates, alkyl betaines, alkylsultaines, alkylamido-propyl-betaines, alkylamido-propyl-hydroxy-sultains and mixtures thereof, wherein said surfactants include C 8 -C 22 alkyl chains and mixtures thereof.

Synthetic surfactants suitable for use in the present invention are disclosed, for example, in U.S. Patent No. 3,351,558 to Zimmerer.

From line 70 to column 7, line 74, which is incorporated herein by reference; and U.S.P. 4,165,293 to Gordon; U. 5,002

685 (Chambers and Instone); U. No. 5,041,234 (Instone et al.), Which are incorporated herein by reference in their entirety. These include alkyl sulfates, anionic acyl sarcosinates, methyl acyl taurates, N-acyl glutamates, acyl isethionates, alkyl sulfosuccinate octates, alkyl phosphate esters, ethoxylated alkyl phosphate esters, , protein condensates, mixtures of ethoxylated alkyl sulfates and alkyl amine oxides, betaines, sultaines and mixtures thereof. Some preferred surfactants are alkyl ether sulfates containing 1 to 12 ethoxy groups, especially ammonium and sodium lauryl ether sulfates.

Particularly interesting synthetic sulfate cleaners are the normally solid alkali metal salts of sulfuric acid esters of C10-C22 normal primary aliphatic alcohols. Thus, the sodium sulfuric acid and potassium salts of alkyl sulfuric acids derived from mixed alcohols obtained from lower alcohols or from coconut oil, palm oil, palm kernel oil, palm oil stearin, babassu seed oil or other oils of the coconut group may be used.

Other aliphatic sulfuric acid esters may also be suitably used. Certain hygroscopic synthetic surfactants, normally used in liquids, which are very difficult to incorporate into ordinary cleaning molds, are very compatible with the inventive moldings. Substantially all known surfactants for use in synthetic cleaning products are thus suitable for use in the compositions of the invention. The patent literature for cleaning compositions is full of synthetic surfactant publications. Preferred synthetic surfactant systems are selectively designed for appearance, stability, foaming, cleaning, and gentleness of the mold.

Preferred foaming synthetic surfactants include C 8 -C 22 alkyl acyl isethionates, acyl sarcosinates, alkyl glyceryl ether sulfonates, methyl acyl taurates, paraffin sulfonates, linear alkyl benzene sulfonates, -glutamates, alkyl sulfosuccinates, α-sulfo fatty acid esters, alkyl ether carboxylates, alkyl phosphate esters, ethoxylated alkyl phosphate esters, α-olefin sulfonate, alkyl ether sulfates ethoxy) and mixtures thereof. Are anionic surfactants are preferred in which the surfactant as alkyl chains contain 8-18, and the counterion is selected from sodium, potassium, ammóniumból, _three of the group consisting of N _{(CH2 CH2} OH).

Some representative examples of preferred surfactants are used in the examples herein. Some of the surfactants with a high degree of gentle, foaming-enhancing synthetic cleansing effect are, for example, sodium lauroyl sarcosinate, alkyl glyceryl ether sulfonate, sulfonated fatty acid esters and sulfonated fatty acids.

It is noted that the mildness of the surfactant can be measured by a skin-wall destruction test used to estimate the irritant potential of surfactants. The gentler the surfactant, the less damage to the skin's protective wall. Dermal wall destruction is measured from the test solution through the epidermis of the skin with the relative amount of radiolabeled water (H-H2O) passed through the physiological buffer in the diffusion chamber. This test was performed by T. J. Franz; J. Invest. Dermatol., 64, 190-195. (1975); and U.S. Patent No. 4,673,525 to Small et al., incorporated herein by reference. These references disclose a synbar-based mild alkyl glyceryl ether sulfonate (AGS) surfactant that contains a " standard (alkyl glyceryl ether) sulfonate " mixture and defines the criteria for a " mild surfactant ". The barrier destruction test is used to select gentle surfactants. Some preferred gentle synthetic surfactants are disclosed in Small et al., Cited above.

SOLVENT: The translucent moldings of the present invention comprise from about 18 to about 37 parts, preferably from about 20 to about 32 parts, more preferably from about 20 to about 28 parts, of a water-soluble organic solvent. The water-soluble organic solvent is preferably selected from the group consisting of urea, water-soluble organic polyol, and mixtures thereof. The urea may be used in an amount of 0 to 8 parts, preferably 2 to 7 parts or 3 to 6 parts, but preferably the total amount of polyol and urea may not exceed 37 parts. Preferred water-soluble organic polyols are selected from the group consisting of propylene glycol "4" ", dipropylene glycol, butylene glycol, glycerol and ethylene glycol, 1,7-heptanediol, mono- and polyethylene and alkyl ethers, sorbitol, glycerol, mono-, di- and triethanolamine, 2-amino-1-butanol, non-reducing sugars such as sucrose, and mixtures thereof.

When a non-reducing sugar is used, it is used in an amount of about 1-10 parts, preferably about 2-7 parts, by weight of the mold. As used herein, the term "sucrose, unless otherwise stated, includes sucrose, its derivatives and similar non-reducing sugars and similar polyols which are substantially stable at a soap treatment temperature of less than about 99 ° C, such as trialose, raffinose and stachyose. ; and sorbitol, lactylol and maltylol.

The water-soluble organic solvent is a necessary component of the invention that is required for the transparency of the mold. Further, to optimize the transparency of the individual cleaning mold, it is important to use a representative amount and type of water-soluble organic solvent.

COMPONENT ASSEMBLY

In order to obtain a translucent mold, the individual cleaning molds of the present invention must contain certain amounts of soap and water-soluble organic solvent. In addition to the minimum amount of solvent and water mentioned above, the amount of total water-soluble organic solvent and water is typically at least 40 parts, preferably 45 parts, by weight of the mold to achieve transparency.

It is also advantageous to combine the water-soluble organic solvent, water, and soap in certain proportions to obtain a translucent mold. Typically, water and the water-soluble organic solvent are preferably combined in a ratio of from about 2: 1 to about 1: 2, most preferably about 1: 1, to maintain transparency.

No. 274,975, which is incorporated herein by reference.

Other clay types are zeolite, kaolinite, montmorillonite, attapulgite, illite, bentonite and halloisite. Another preferred clay is kaolin.

MOLDING PROCESS: Transparent cleaning molds of the present invention are produced by a non-alcoholic molding process. The method: (A) 18 to 35 parts soap, wherein the soap contains at least 50% insoluble soap; 14-32% water; 5-37% synthetic surfactant and

Preparing a bulk mixture containing 18-37 parts water soluble organic solvent; and (B) transferring a unit amount of said bulk blend to a mold forming mold and allowing said molded unit to cool (without mixing or shearing) to a gentle, low-lubricating translucent individual cleaning mold.

A preferred non-alcoholic process comprises the following steps:

1. Mixing an almost insoluble fat selected from the group consisting of triglycerides and fatty acids with a water-soluble organic solvent selected from the group consisting of polyols and mixtures thereof;

2. Add the amphoteric surfactant (s), water, and any salt (s), such as sodium chloride, while stirring;

3. Raising the temperature of the mixture of Step 2 from 70 ° C to 100 ° C to obtain a bulk mixture;

4. Add sufficient alkaline solution for saponification of the fat material to the mixture of Step 3 and, after saponification / neutralization, provide a small amount of free alkali; if necessary to prevent source, cool but maintain bulk mixture;

5. Add to the mixture of Step 4 all free fatty acids (at least sufficient to neutralize all free alkalis) and optionally other synthetic surfactants;

6. Set the mixture temperature to a maximum of 85 ° C;

7. While stirring, add other optional ingredients while maintaining the temperature at 68-85 ° C;

8. Pour the bulk mixture into molds or tubes;

• ·

9. The mixture in the molds or tubes is conditioned to promote crystallization / solidification. Cooling should be conducted under quiet conditions at product temperatures below 68 ° C. An average cooling rate of 0.1 to 7.0 ° C / min is preferred;

10. Slice the soap plugs into piece-sized plugs if tubes are used;

11. Press into molded rods and package the molded rods provided.

A preferred method is the framed beam method. Other methods, such as injection molding, may also be used.

EXAMPLES

The following procedure is used to prepare the casting rods exemplified below. The procedure includes the following steps:

1. A step of preparing a melt mixture portion as follows.

2. Pour the molten mixture product into rod molds or tubes.

3. Cool the rods under calm conditions to promote crystallization / solidification.

4. Once filled into the tubes, the soap plugs are sliced into mold-sized plugs.

5. Press and package the molds.

Batch procedure

1. Mix triglycerides (e.g. hardened tallow) and / or fatty acids (e.g. laurin

acid) with a water-soluble polyol (e.g., propylene glycol).

2. Add amphoteric surfactants (such as coconut betaine), water, and salts (such as sodium chloride) to the vessel.

3. Raise the batch temperature from 70 ° C to 100 ° C.

4. Add sufficient alkaline solution (for example, 30% sodium hydroxide) so that a small amount of free alkali remains after saponification / neutralization. Cool the dose if necessary to prevent source.

5. Add free fatty acid as needed.

6. Add other synthetic surfactants (such as sodium laureth-3-sulfate) to the dose as needed.

7. Set the batch temperature to a maximum of 85 ° C.

8. Add any other ingredients (e.g. sugar, perfume) that may be used in the portion.

Temperatures in the process may vary slightly within, for example, 5 ° C. The key issue is not to allow the molten mixture to become too high in viscosity (e.g., as typically occurs at temperatures below 68 ° C) and to avoid stirring while cooling the mix.

The following examples illustrate the invention and are not intended to limit it. Unless otherwise specified, all percentages, parts, and ratios are by weight herein. The free acids used in the examples are used in the same proportions as in the fatty acid soaps. Soaps are prepared in situ unless otherwise specified. The amount of soap is expressed as a percentage of the total soap and as a percentage by weight of the bar.
