Definitions

  • a milled and plodded toilet soap bar comprises 70-80% sodium salt of higher fatty acids of 8 to 20 carbon atoms, of which acids 90- 75% thereof is of fatty acids of 16 to 20 carbon atoms and 1025% thereof is of saturated fatty acids of 8 to 14 carbon atoms, 4 to 7% of a mixture of hydrocarbons of about 16 to 32 carbon atoms and a glycerol content of 30 to 70% of the hydrocarbon weight.
  • a bar of this description is particularly suitable for cleansing dry skin and simultaneously deposits oleaginous soap bar constituent on the skin.
  • a milled and plodded toilet soap bar comprises 78% settled white sodium soap derived from a mixture of about 20 parts coconut oil and 80 parts tallow, about petrolatum, 2.5% glycerol, 1.5% lanolin, 12% Water and 1% adjuvants.
  • the soap employed is one from which substantially all inorganic salts, unreacted fats and oils and glycerol have been removed.
  • the product has been found to deposit petrolatum on the skin in normal washing, leading to a higher lipophilic 'ice content thereof and improving the appearance and feel of the skin, as well as counteracting the tendency to drying of the skin after washing.
  • the water soluble soap which is the major constituent of this product and contributes most to its desirable physical properties, such as cleaning power, satisfactory solubility, processability and appearance, as well as other use characteristics associated with good toilet soaps, is a mixture of sodium salts of higher fatty acids of 8 to 20 carbon atoms.
  • the proportion of soaps containing 8 to 14 carbon atoms should be kept low in this bar, intended primarily for use in the cleansing of skin deficient in natural oils. Soaps of 8l4 carbon atoms are less unctuous in feel than the higher and unsaturated soaps and thereby give some users the impression that their application is drying to the skin.
  • soaps have been reported to be harsher to the skin than those of higher fatty acids but, when mixed with higher soaps, as in the present bars, no significant change in mildness was observed.
  • Some lower saturated fatty acids of 8 to 14 carbon atoms should be present to give the soap a balanced mixture of detergents which is more amorphous, foams more quickly and better removes various types of dirt and soil from the skin. It has been found that at least 10% is desirable for these purposes and it is preferable that no more than 25% of the saturated soaps of 8 0t 14 carbon atoms should be present.
  • the balance of the soap constituent is a mixture derived from fatty acids of 16 to 20 carbon atoms.
  • Such a mixture will contain predominant proportions of stearic, oleic and palmitic acid soaps with minor proportions of palmitoleic and arachidic soaps sometimes present.
  • These higher fatty acid soaps give the bar a slip and oily feel to the skin when they are employed in the described proportions in a toilet soap of this composition and such a slip or lubricity is desirable in the present bars.
  • C -C 90 015-020 soap ranges a commercially acceptable and proven soap is obtained which can be manufactured easily and has the desirable combination of properties which suit it for use in a product primarily intended for cleansing dry skin.
  • composition of this invention is primarily a soap bar with additional desirable characteristics resulting from the presence of the other recited constituents.
  • the amount of sodium soap present should be within the range of 7080% of the bar.
  • the sodium soaps in the present bars may be made by the usual soap making techniques which result in a product essentially free of inorganic salt, glycerol, unsaponified and unsaponifiable materials. It is preferred to use settled white kettle soap of good quality, which has been dried into the usual ribbon or chip form.
  • the oil charge employed to obtain such a soap of higher fatty acid content specified is preferably composed of coconut oil and tallow. It is preferred to use parts tallow and 20 parts coconut oil but the proportions may be varied from 94:10 to 75:25.
  • a bar containing only soap and the proportion of petrolatum recited is significantly different in some respects from a soap bar and, in general, the comparison of physical and processing properties, apart'from 'superfatting effect, is unfavorable to the petrolatum-containing detergent.
  • the petrolatum or hydrocarbon oil mixture tends to soften the soap and make it more difficult to process. It also affects the performance and feel of a wetted bar, tending to slow down the development of good lathering and to reduce the desirable slipperiness of the bar.
  • glycerol a sufficient quantity of glycerol, in accordance with this invention, has a benficial result on the product performance and helps it to be efficiently made in standard soap manufacturing equipment.
  • the percentage of glycerol employed should be about half as much as that of petrolatum and preferably 2.5% glycerol is used.
  • the glycerol content may be between 30 and 70% of the petrolatum weight.
  • lanolin preferably 1.5%
  • the lanolin more closely approximating the chemical nature of the sebum, supplements the petrolatum and improves conditioning of the skin.
  • Lanolin usually has a very detrimental effect on lathering power of soap, even more so than petrolatum, but
  • small percentages of adjuvants may be used to give the bar special desired properties and to improve its stability.
  • the proportion of adjuvants is preferably kept low to maintain the essential soap-like characteristics of the bar.
  • the adjuvants employed may be mentioned perfume, fluorescent dyes, stabilizers, antioxidants, solvents, pigmeuts and coloring agents.
  • Sodium metabisulfite in the formula even only at 0.1 to 0.2%, significantly improves the bar color on storage and is a preferred stabilizing and bleaching agent.
  • the solvents polyethylene glycol is preferably employed to dissolve bactericide, e.g., tetrachlorsalicylanilide, and better distribute it through the bar, when it is in the formula.
  • the content of additives will be less than 5 and preferably less than 2%.
  • the formula given above was made with 6.0% petrolatum, instead of the combination of petrolatum and lanolin, other constituents remaining constant, except for a compensating increase in soap content.
  • the bar made was made according to the same method, was tested and was found to be satisfactory but the lanolin-petrolatumglycerine combination is preferable. Subjects with dry skin conditions, who employed these bars, noted with approval the better feel of the skin and an increase in softness and suppleness, together with an improvement in appearance.
  • a milled and plodded toilet soap bar particularly suitable for cleansing dry skin and depositing oleaginous soap bar constituent on the skin comprising 70-80% of soap substantially free of inorganic salts, unreacted fats and oils and glycerol, the soap being of higher fatty acids of 8 to 20 carbon atoms predominantly of 16 to 18 carbon atoms, 10-25% of the soap being of saturated fatty acids of 8 to 14 carbon atoms and 90-75% of 16 to 20 carbon atoms, being that derived from an oil charge of 10 to coconut oil and 90-75% tallow, 4 to 7% petrolatum, to of the petrolaturn of glycerol, 1 to 2.5% lanolin and 10 to 16% water.
  • a milled and plodded toilet soap bar particularly suitable for cleansing dry skin and depositing petrolatum on the skin comprising about 78% settled White sodium soap derived from a mixture of about 20 parts coconut oil and 80 parts tallow, which soap is substantially free of inorganic salts, unreacted fats and oils and glycerol, about 5% petrolatum, about 2.5% glycerol, about 1.5% lanolin and about 12% water.
