U. S. Pat. no. No. 3,761,418, 1973, no Non-particulate detergent compositions, disclose detergent compositions wherein the surfactant is an alkylsulfur, but which is unacceptable to the delicate skin cleansing compositions of the present invention.

The most common drawbacks of most synthetic surfactant toilet bar formulations are roughness, lack of soap, poor spreadability and poor processability due to tackiness. By using high-soap anionic substances an acceptable foam volume can be achieved. However, the most foaming anionic surfactants are in fact poorly processable. Although some known fine mixtures of soda-cocoon e tallow alkyl glyceryl ether sulfonst (AGS) are relatively good in terms of foaming, they cannot be easily processed due to their stickiness or hygroscopicity. When selecting a surfactant for fine cleaning sticks for personal hygiene, it is particularly important to take into account the workability, stability, spreadability, softness, soap and rinsability of the surfactant. Thus, when formulating fine personal cleansing bars, high demands are placed on the choice of surfactants and the final formulations are a degree of compromise. Fineness is often achieved at the expense of processability, effective cleansing soap or rinsability, or vice versa. However, fettability is achieved at the expense of spreadability.

It should be noted that the cleansing bar, the readability is sufficient, it is very difficult that the advantageously refined fine composition for each has a satisfactory fineness, a good separating power and a good rinsability, to assemble / formulate /

Num! of the invention

One object of the present invention is a molded fine personal cleansing bar with improved manufacturing ability.

Another object of the invention is a fine bar with excellent spreading of the bar.

Yet another further object of the invention is to build / formulate / a fine personal cleansing bar with a relatively low level of free fatty acids, thereby improving the spreadability and stability of the bar.

Other objects of the invention will become apparent from the following detailed description.

The gentle personal cleansing bar comprises about 20 to 50% foaming fine surfactant and about 5 to 50% magnesium soap. The ratio of foaming fine synthetic surfactant to soap is about 10: 1 to 0.4: 1. The bar has a pH of about 6.5 to 8.5 in a 1% aqueous solution at 25 ° C. The preferred pH value of the bar is 7-8 e is preferably treated with a carboxylic acid, pH is measured in a flaxseed aqueous solution at 25 ° C.

The ratio of foaming fine synthetic surfactant to magnesium soap is about 10: 1 to 0.4: 1, preferably about 5: 1 to 0.4

0.5: 1, more preferably about 4: 1 to 0.6: 1.

The term foaming fine synthetic surfactant as used herein means any surfactant that foams at least as well as the fine standard alkyl glyceryl ether sulfonate (AGS) as defined herein, containing a substantial amount of C ^ 2 ^{8 c} ^ 4 tartaric surfactants. chains specified about 68% C ₁₄ and 7% C ₁₆ AGS.

However, they mainly improve the ability of the bar to have a good degree of flex test, as described in more detail below. They also improve the smear characteristics of the bars.

The terms dirt diluent and hydrophobic material as used herein are synonymous and mean dirt-dissolving diluent based on free fatty acid, paraffin wax, aliphatic alcohol or triglycerides. some of these squadrons, like para fin wax, very effectively improve the flex test grades. Other substances such as e.g. free fatty acid helps to soften the composition for production.

The hydrophobic substance / diluent soil / can be included in the bars of this invention in an amount from zero to about 40%, using the treble preferably of about 5 to 20 Other hydrophobic materials include free fatty acids containing from about 8 to about 18 carbon atoms ^1, the name di- and triglycerides, fatty alcohols containing from about 8 to 18 carbon atoms, and mixtures thereof, said mixture containing at most about 25% of said waxes and at most about 15% of other hyirophobic substances. Triglycerides (the Cg-gecyl chain) can be used up to about 10% without effectively adversely affecting unacceptable foam formation.

A preferred hydrophobic material is a wax with a melting point of about 49-85 ° C, preferably about 52-79 ° C. A preferred paraffin wax is a fully refined paraffin wax having a melting point of about 49-60 ° C. This wax is odorless and tasteless and meets the FDA requirements for use as coatings for food and packaging. Such paraffins are readily obtainable commercially. A very suitable paraffin can be obtained, for example, from Standard Oil firm The ^c ompany of Ohio under the trade name Factowax R-133rd

Other suitable waxes are sold fa fa aiional ´7ax ^ o. under the trademarks 9162 and 6971 with a temperature of -55 ° C.

The preferred amount of paraffin in the bar is about 5 to 20% by weight. The paraffin additive in the product gives it softness to the skin, plasticity, durability and processing ability. It also achieves a glossy appearance and a gentle touch of the sticks.

The paraffin component is optionally supplemented with a microcrystalline wax. A suitable microcrystalline wax has a melting point of, for example, about 60 to 85 ° C, preferably about 62 to 79 ° C. The wax should preferably meet the FDA requirements for the food grade microcrystalline waxes.

_ Q _

A very suitable microcrystalline wax is available from Witco Chemicsl Company under the trademark Multi-vax .X-145A. The microcrystalline wax is preferably contained in an amount of about 0.5 to 5% by weight. Further crystalline wax confers flexibility to the bar at room temperatures.

The non-precipitating surface-active diluent may be used in an amount of 0 to about 40%, preferably about 5 to 40, 6, and more preferably about 10 to 35.

The amount of water is about 2 to 15%, preferably about 4 to 10%.

The total level of non-surface-active electrolyte (organic or inorganic) is about 1 to 10%, preferably about 2 to 8%, more preferably about 2 to 5%, of the weight of the rod.

Many examples of surfactants are mentioned in the patents cited herein by reference. These include alkyl sulfates, anionic ethyl sarcosinates, methylecyltaurates, N-acylglutamates, alkylsulfosuccinates, alkylphosphate esters, ethoxylated alkylphosphonate esters, tridecetsulfates, protein condensates, mixtures of ethoxylated alkylsulfates and betaine alkyleside oxides. Included in the surfactants are alkyl ethersulfates having 1 to 12 ethoxy groups, in particular ammonium and sodium lauryl ethers.

Alkvlové chains for these surfactants are θ ₆ _22 advantageously for lathering mild surfactants e for non-foaming soil-load diluents.

As used herein, the term "alkyl glyceryl ether sulfonate" generally refers to a mixture of alkyl glyceryl ether sulfonate (AGS) surfactants having an alkyl chain of 8-22 carbon atoms, preferably 10-20 carbon atoms, and more preferably 12-14 carbon atoms.

Alkyl glyceryl ether sulfonates are derived from the corresponding ethers composed of straight chain alkyl chains, which in turn are derived from their corresponding synthetic or natural alcohols.

U. pet. no. No. 4,673,525 to Small et al. Discloses a mild alkyl glyceryl ether sulfonate surfactant as the basis for a fine cleaning bar. The fine personal cleansing bars of the present invention are easier to manufacture than the fine personal cleansing bars described in the Examples of Small et al. In other words, the improved cleansing bars of the invention can be made better than AGS soap bars. The bars according to the invention are also better in terms of stability and resistability.

Alkyl glycosides and methylglucose esters are preferred nonionic materials which can be mixed with at least one of said mild anionic or amphoteric surfactant in the preparation of the compositions of the invention.

The preferred additive is isethionate. Acyl isethionates are esters of aliphatic higher fatty acids with alkali metal salts of isethionic acid and can be defined by the general formula RCOOC2 Cl2 SO 4 M wherein R is an aliphatic radical or mixed aliphatic radical of a higher fatty acid or a mixture of acids having about 6 to 20 carbon atoms, preferably about 8 to 18, e.g. coke or approximately equivalent chain length distribution. The longer chains (16 and 18) are more suitable than non-foaming, non-dirt-precipitating diluents and middle chains are more preferred than foaming synthetic surfactants, and M is an alkali metal cation such as sodium, potassium, or ammonium, or an organic amine base such as triethanolamine, triisopropanolamine, diethanolemine, ethanolamine. Sodium is the preferred cation in AGS and acylisethionate salts.

A preferred knurled rod for determining the fineness by the flex test comprises; (1) about 25 to 25%, preferably about 10 to 20% of alkylsulfates; and (2) about 9 to 50%, preferably about 1 to 30% of magnesium soap based on the soap bar. E.g. in Example 7 below, foaming fine synthetic surfactants are also required for this preferred bar. The ratio of electrosulfates to magnesium soap may be about 3: 1 to 1: 6, preferably about 1: 2 to 1: 4. This non-precipitating, non-foaming, synthetic surfactant diluent is surprisingly and unexpectedly an excellent diluent for frothing ultra-moderately synthetic surfactants, e.g. Alkyl glyceryl ether sulfonate and / or cocoyl isethionate in personal cleansing bar compositions. Synthetic surfactant diluents provide a surprisingly acceptable improvement in the processability of the bar without significantly affecting the fineness of the bar or its desired physical characteristics.

The C 18 alkyl alkyl sulfates are derived from the corresponding saturated straight chain alcohols. The alkyl sulfates defined herein comprise C8-18 alkyl chains in an amount of at least 90%, preferably about 93%, and more preferably about 97%. In general, the ratio of C 1 to C 1 can be in the range of about 4: 1 to 1: 4 by weight. Commercially available ^C 16-18 ^alkyl sulfates are SIPON ® EC-111 (formerly SIPEX ® EC-111).
