Abstract
Disclosed is a mild skin cleansing bar composition comprising: mild synthetic surfactants, moisturizers, polymeric skin feel and mildness aids, selected levels of soap, and low moisture content to provide improved in use properties with regard to bar firmness and reduced messiness. Also disclosed is an ultra mild skin cleansing bar composition comprising: a mixture of selected polymeric skin feel and mildness aids and selected levels of soap. An ultra mild skin cleansing bar is provided which is clinically milder on the skin than water and has improved rinsing, firmness and reduced messiness.
Claims27
An ultra mild firm, stamped, toilet synbar comprising:
- A. 20-70% mild synthetic surfactant;
- said mild synthetic surfactant having a Relative Skin Barrier Penetration Value of less than about 40;
- B. 10-40% moisturizer;
- C. 5.5-25% soap;
- D. 0.1-5% of a polymeric skin feel and mildness aid;
- E. 3.5%-4.5% water;
- and
- wherein said synbar has improved bar firmness over comparable bars having higher water levels;
- and wherein said polymeric skin feel and mildness aid are selected from the group consisting of:
- quaternary ammonium salt of hydroxyethylcellulose;
- guar hydroxypropyltrimonium chloride;
- hydroxypropyl guar, and diallyldimonium chloride/hydroxyethylcellulose copolymer;
- polymeric quaternary ammonium salt of acylamide and dimethyldiallyl ammonium chloride monomers;
- poly (dimethyldiallyl ammonium chloride);
- and polymers having the following structural formula:
- ##STR2## wherein x is about 6;
- and mixtures thereof wherein said synthetic surfactant and said soap have a ratio of from 2:1 to 12:1, and
- wherein said moisturizer to soap has a ratio of from 1:1 to 7:1.
An ultra mild, stamped, toilet bar comprising:
- A. 20-70% mild synthetic surfactant;
- said mild synthetic surfactant having a Relative Skin Barrier Penetration Value of less than about 40;
- B. 10-40% moisturizer;
- C. 5.5-25% soap;
- and
- D. 0.1-5% of a mixture of at least two polymeric skin feel and mildness aids wherein an effective amount of a first of said aids is selected primarily for skin mildness and an effective amount of a second of said aids is selected primarily for its low slipperiness in rinsing;
- wherein said ratio is 4:1 to 1:4;
- and wherein said first polymeric skin feel and mildness aid are selected from the group consisting of:
- quaternary ammonium salt of hydroxyethylcellulose;
- guar hydroxypropyltrimonium chloride;
- hydroxypropyl guar, and diallyldimonium chloride/hydroxyethyl-cellulose copolymer and mixtures thereof;
- and said second polymeric skin feel and mildness aid is selected from the group consisting of poly (dimethyldiallyl ammonium chloride);
- polymeric quaternary ammonium salt of acylamide and dimethyldiallyl ammonium chloride monomers;
- and polymers having the following structural formula:
- ##STR3## wherein x is about 6;
- and mixtures thereof wherein said synthetic surfactant and said soap have a ratio of from 2:1 to 12:1, and
- wherein said moisturizer to soap has a ratio of from 1:1 to 7:1.
An ultra mild, stamped, toilet synbar comprising:
- A. 20-70% mild synthetic surfactant;
- said mild synthetic surfactant having a Relative Skin Barrier Penetration Value of less than about 40;
- B. 10-40% moisturizer;
- C. 5.5-25% soap;
- and
- D. 3.5%-4.5% water;
- and wherein said synbar has improved firmness over comparable synbars having higher water levels wherein said synthetic surfactant and said soap have a ratio of from 2:1 and wherein said moisturizer to soap has a ratio of from 1:1 to 7:1.
