Abstract
This invention relates to a system for cleansing the skin comprising a hydrophobic diamond-mesh sponge and a liquid cleansing and moisturizing composition with excellent lather in the same washing and rinsing operation. The system provides improved lather and overall acceptability for mild liquid cleansing compositions which contain moisturizers and especially for those which would otherwise have marginal lather.

A personal bath or shower body cleansing and lathering product comprising:
- (a) a personal cleansing implement comprising hydrophobic polymeric netted mesh;
- and
- (b) a cleansing and moisturizing liquid emulsion having at least two phases, wherein said liquid emulsion comprises:
- (1) a moisturizing phase comprising from about 0.5% to about 33.5% by weight of the liquid emulsion of a skin conditioner ingredient selected from the group consisting of esters of fatty acids, glycerin mono-esters, glycerin di-esters, glycerin tri-esters, epidermal and sebaccous hydrocarbons, lanolin, mineral oil, silicone oil, silicone gum, vegetable oil, petrolatum, vegetable oil adduct, cationic polymers and mixtures thereof;
- and
- (2) an aqueous cleansing phase comprising i) from about 0.5% to about 30% by weight of the liquid emulsion of a lathering surfactant selected from the group consisting of anionic surfactants and mixtures of anionic surfactants;
- wherein the surfactant or mixture of surfactants has an equilibrium surfacc tension ranging from about 15 to about 50 dynes/cm as measured at the critical miscelle concentration at 25.degree. C.;
- and ii) water.
A personal bath or shower body cleansing and lathering kit comprising:
- (a) a light weight, hydrophobic, polymeric, netted, diamond mesh, hand-held personal cleansing sponge;
- said hand-held sponge having a diameter of from about 5 centimeters to about 20 centimeters;
- and
- (b) a cleansing and moisturizing liquid emulsion comprising:
- (1) a moisturizing phase comprising from about 1.0% to about 15% by weight of the liquid emulsion of a skin conditioner ingredient selected from the group consisting of esters of fatty acids, glycerin mono-esters glycerin di-esters, glycerin tri-esters, epidermal and sebaccous hydrocarbons, lanolin, mineral oil, silicone oil, silicone gum, vegetable oil, petrolatum, vegetable oil adduct, cationic polymer and mixtures thereof;
- and

- and (2) an aqueous cleansing phase comprising:
- i) from about 0.5% to about 30% by weight of the liquid emulsion of a lathering surfactant selected from the group consisting of anionic surfactants and mixtures of anionic surfactants;
- wherein the surfactant or mixture of surfactants has an equilibrium surface tension ranging from about 15 to about 50 dynes/cm as measured at the critical miscelle concentration at 25.degree. C.;
- and ii) water.
A method of cleansing and moisturizing the skin comprising applying a cleansing and moisturizing liquid emulsion to a personal cleansing implement comprising hydrophobic polymeric netted mesh, working the cleansing and moisturizing liquid emulsion into a lather, and applying the lathered emulsion to the skin with the personal cleansing implement;
- wherein said cleansing and moisturizing liquid emulsion has at least two phases comprising:
- (1) a moisturizing phase comprising from about 0.5% to about 33.5% by weight of the emulsion of a skin conditioner ingredient selected from the group consisting of esters of fatty acids, glycerin mono-esters, glycerin di-esters, glycerin tri-esters, epidermal and sebaceous hydrocarbons, lanolin, mineral oil silicone oil, silicone gum, vegetable oil, petrolatum, vegetable oil adduct, cationic polymer and mixtures thereof;
- and (2) an aqueous cleansing phase comprising:
- i) from about 0.5% to about 30% by weight of the emulsion of a lathering surfactant selected from the group consisting of anionic surfactants and mixtures of anionic surfactants;
