TECHNICA~ fIEL~
The present inYention relates to compositions which provid~
both a skin cleansing ~nd skin moisturizing benefit from the same product. These compositions provide improved lathering and cleansing characterist1cs, are extremely mild to the skin, and upon rins~-off del~ver a moisturlz1ng agent to the sktn. These composlt~ons compris2 at leas~ one anionic surfactant, a dispersed, lnsoluble oil phase, at least one additional surfactant selected from nonionic~ zwitterionic and amphoteric surfactants, an option~l suspending agent, and water ~his invention also relates to methods for provid1ng combined cleansing and I5 motsturization, and to methods for deliverin~ these compos1tions as a foam.
~CKGROUND Of TH~ Ie~EgllON
Cleanslng compos~tions must sat~sfy a number of criteria including cleansing power, foaming properties, and mildness/low lrritancy with respect to the sk~n, ha1r and the occular mucosae.
Sk1n ~s made up o~ several layers of cells wh1ch coat ~nd : protect the kerattn and collagen ftbrous proteins that form the skeleton of~ its structur~. The outermost of these layers, referred to as the stratum corneum, is known to be composed of Z50 ~ diameter prcte1n bundles surrounded by 80 ~ th~ck bi1aye'rs of epidermal l~p~ds and wa~er. Anionic surfactants can penetrate the stratu~ c~rneum membrane and, by delipid~zation (~.e. removal of th~ lip1ds from th~ stratum corneum~, destroy its integrity. This destruct10n of the stratum corneum bilayers can lead to dry rough sk1n and may eventually permit the surfactant to interact with the viable epiderm~s, cre~ttng irr1tat10n.
Ideal cosmet k~ cleans~rs sh~uld cleanse the skin gently, ~ausing little or n~ ~rritat~on without defatt1ng and or drying ~: the sk~n and without leaving skin taut a~ter frequent use. Most 3s lathering~soaps, 1iquids and bars fai1 in this respect. Also, most current cleans1ng~ products do not deliver an adequate :
, : ~:
Wo 93/09761 P~tUS92~ ~9 moisturizîng benefit during cleansing. Therefore, users typically must moisturize their skin in a separate step following cleansing.
Certain synthetic surfactants are known to be mild. However, a major drawback of most mild synthetic surfactant systems, when formulated for skin cleansing, is poor lather performance compared to the highest bar soap standards (bars which are rich in coconut soap and superfatted). On the other hand~ the use of known high sudsing anionic surfactants with lather boosters can yield acceptable lather volume and qua1ity. Unfortunately, however, the highest sudsing anionic surfactants are, in fact, poor in clinical skin mildness. Surfactants that are a~ong the mildest, such as sodium lauryl g1yceryl ether sulfonate, (AGS), are marginal in lather. These two facts ~ake the balancing of the surfactant selection and the lather and skin feel benefit a delicate process.
I5 Rather stringent requirements for cosmetic cleansers limit the choice of surface-active agents, and final formulations represent some degree of compromtse. Mildness is often obtained at the expense of effective cleansingl or lathering may be sacrificed for either mildness t product stability, or both Furthermore, it would be highly desirable to alss deliver skin moisturizers from cleanslng compositions, because this would pro~ide users with the convenience of obtaining both a cleansing and a moisturizing benefit from a single product. However, such dual cleansing and moisturizing compositions are difficult to 25 formul ate because the cl eans i ng ingredients, in general, tend to be incompa~ible with the moisturizing ingredients. ~
Thus a need exists for cleansing compositions which will produce a foam which is abundant, stable and of high quality (com-pactness), which are effective skin cleansers, which are very mild to the skin and occular mucosae, and which can also deliver a moisturizing agent to the skin.~These combined skin cleansing and `~ ` ' moisturizing compositions would be termed two-in-one c1eansers because of the dual cleansing and moisturizing benefits they would provide. ~
One highly successful solution to this dilemma of delivering both a cleansing and conditioning benefit from the same product has been in thF ,hampoo irea. Two-in-one conditioning shampoos UO g3/09~61 2 1 2 2 2 7 2 PCT/US92~09~29 have been developed which deliver suspended silicone hair conditionin~ agents in the presence of various cleansing surfactants. See U.S. Patent No. 4,788,006, to Bolich, Jr. et al., issued November 29, 1988; U.S. Patent No. 4,741,855, to Grote et al, issued May 3, 1988; and U.S. Patent No. 4,704,272, to Oh et al., issued November 3, 1987. Shampoos, though, generally ccntain higher levels of more potent surfactants than are needed or desirable for gently cleansing the skin~ because the hair has a ~arger surface area compared to the sk~n and tends to beoome soiled with higher levels af sebum, dirt~ and other debris.
Conversely, the hair generally requires much lower levels of canditioners than the skin, because the hatr is easily overcondittoned resulting in limp, unmanageable, and resoiled hair. Thus, it is seen that cleans1ng and moisturizing the skin is different from cleansing and condltioning the hair. Therefore, it would be highly desirable to develop effective, yet gentlel skin cteansing compositions which would also provide a skin moisturizing benefit.
It is therefore an object of the present invention to provide improved personal cleansing compositions which thoroughly cleanse the skin and which also moisturize the skin, i.e. to provide combined skin cleansing and moisturizing compositions.
It is a further object of the present ~nvention to provide combined cleansing and moisturizing compositions whish are very mild to ~he skin and occular mucosae.
It is an even further object of the present invention to provide combined cleansing and molsturizing compositions which will produce a foam which is abundant, stab1e, and of high qu~l~ty.
It is a still further object of the present invention to provide methods for~cleansing and mo~sturizing the skin.
It is la ~et further ~object of the present invcntion to provide methods for delivering combined cleansing and moisturizing compositions as foams.
35~ These and other object;s wil1 become readily apparent from the detailed description~which follows.

For delivery as a foam, the compositions of the instant invention can be del ivered, for example, from a hand-held device such as a nonaerosol pump foamer or from an aerosol container charged with a suitable propellant system.
Non-aerosol squeeze f~amer packages are well known as exemplified by the disclosur~s in the following patents that are incorporated herein by reference. U.S. Patent No~ 3,7~9,437~ to Wright, ~ssued January 9, 1973; U.S. Patent No. 3,937,364, to Wright, issued February 10, 1976; U.S. Patent No. 4,022,351, to Wright, lssued May 10, 1977; U.S. Patent Mo. 4,147,306, to Bennett, issued April 3, 1979, U.S. Patent No. 4,184,615, to Wright, issued January 22, 1980; U.S. Patent No. 4,598,862, to Rice, issued July 8, 1986; U.S. Patent No. 4.615,467, to Grogan et al., iss~ed Octob~r 7, 1986; and French Patent No . 2 , 604 , 622 , to Verhulst, published April 8, 1988. These containers ~packages) do not use any propellant. They create a foam from almost any surfactant composition. The composition is placed in the container reservoir (plastic squeeze bottle). S~ueezing the container with the hand forces the composit~on through a foamer head, or other foam producing means, where the composition is mixed with air and then through a homogenizing means that makes the foam more homogeneous and controls the consistency of the foam. The foam is then dlscharged as a uniform, non-pressurized aerated foam.
Press~rized ~erosc1 delivery systems are also well-known in the art.: ~hen the;compositions of the instant inventian are del~vered:from such pressurized systems, the compositions further compr~se from ~bout 2S% to about 80%, preferably from about 307. to about 50%, of suitable propellants. Examples of such propellants are the chiorinated, fluorinated, and chlorofluorinated lower molecular weight hydrocarbons; nitrous oxide; carbon dioxtde;
butane; propane; and the like. These prope1lants are used at a ~35 level sufftcient to exp:el the contents of the container.

.
TECHNICA~ fIEL~
The present inYention relates to compositions which provid~
both a skin cleansing ~nd skin moisturizing benefit from the same product. These compositions provide improved lathering and cleansing characterist1cs, are extremely mild to the skin, and upon rins~-off del~ver a moisturlz1ng agent to the sktn. These composlt~ons compris2 at leas~ one anionic surfactant, a dispersed, lnsoluble oil phase, at least one additional surfactant selected from nonionic~ zwitterionic and amphoteric surfactants, an option~l suspending agent, and water ~his invention also relates to methods for provid1ng combined cleansing and I5 motsturization, and to methods for deliverin~ these compos1tions as a foam.
~CKGROUND Of TH~ Ie~EgllON
Cleanslng compos~tions must sat~sfy a number of criteria including cleansing power, foaming properties, and mildness/low lrritancy with respect to the sk~n, ha1r and the occular mucosae.
Sk1n ~s made up o~ several layers of cells wh1ch coat ~nd : protect the kerattn and collagen ftbrous proteins that form the skeleton of~ its structur~. The outermost of these layers, referred to as the stratum corneum, is known to be composed of Z50 ~ diameter prcte1n bundles surrounded by 80 ~ th~ck bi1aye'rs of epidermal l~p~ds and wa~er. Anionic surfactants can penetrate the stratu~ c~rneum membrane and, by delipid~zation (~.e. removal of th~ lip1ds from th~ stratum corneum~, destroy its integrity. This destruct10n of the stratum corneum bilayers can lead to dry rough sk1n and may eventually permit the surfactant to interact with the viable epiderm~s, cre~ttng irr1tat10n.
Ideal cosmet k~ cleans~rs sh~uld cleanse the skin gently, ~ausing little or n~ ~rritat~on without defatt1ng and or drying ~: the sk~n and without leaving skin taut a~ter frequent use. Most 3s lathering~soaps, 1iquids and bars fai1 in this respect. Also, most current cleans1ng~ products do not deliver an adequate :
, : ~:
Wo 93/09761 P~tUS92~ ~9 moisturizîng benefit during cleansing. Therefore, users typically must moisturize their skin in a separate step following cleansing.
Certain synthetic surfactants are known to be mild. However, a major drawback of most mild synthetic surfactant systems, when formulated for skin cleansing, is poor lather performance compared to the highest bar soap standards (bars which are rich in coconut soap and superfatted). On the other hand~ the use of known high sudsing anionic surfactants with lather boosters can yield acceptable lather volume and qua1ity. Unfortunately, however, the highest sudsing anionic surfactants are, in fact, poor in clinical skin mildness. Surfactants that are a~ong the mildest, such as sodium lauryl g1yceryl ether sulfonate, (AGS), are marginal in lather. These two facts ~ake the balancing of the surfactant selection and the lather and skin feel benefit a delicate process.
I5 Rather stringent requirements for cosmetic cleansers limit the choice of surface-active agents, and final formulations represent some degree of compromtse. Mildness is often obtained at the expense of effective cleansingl or lathering may be sacrificed for either mildness t product stability, or both Furthermore, it would be highly desirable to alss deliver skin moisturizers from cleanslng compositions, because this would pro~ide users with the convenience of obtaining both a cleansing and a moisturizing benefit from a single product. However, such dual cleansing and moisturizing compositions are difficult to 25 formul ate because the cl eans i ng ingredients, in general, tend to be incompa~ible with the moisturizing ingredients. ~
Thus a need exists for cleansing compositions which will produce a foam which is abundant, stable and of high quality (com-pactness), which are effective skin cleansers, which are very mild to the skin and occular mucosae, and which can also deliver a moisturizing agent to the skin.~These combined skin cleansing and `~ ` ' moisturizing compositions would be termed two-in-one c1eansers because of the dual cleansing and moisturizing benefits they would provide. ~
One highly successful solution to this dilemma of delivering both a cleansing and conditioning benefit from the same product has been in thF ,hampoo irea. Two-in-one conditioning shampoos UO g3/09~61 2 1 2 2 2 7 2 PCT/US92~09~29 have been developed which deliver suspended silicone hair conditionin~ agents in the presence of various cleansing surfactants. See U.S. Patent No. 4,788,006, to Bolich, Jr. et al., issued November 29, 1988; U.S. Patent No. 4,741,855, to Grote et al, issued May 3, 1988; and U.S. Patent No. 4,704,272, to Oh et al., issued November 3, 1987. Shampoos, though, generally ccntain higher levels of more potent surfactants than are needed or desirable for gently cleansing the skin~ because the hair has a ~arger surface area compared to the sk~n and tends to beoome soiled with higher levels af sebum, dirt~ and other debris.
Conversely, the hair generally requires much lower levels of canditioners than the skin, because the hatr is easily overcondittoned resulting in limp, unmanageable, and resoiled hair. Thus, it is seen that cleans1ng and moisturizing the skin is different from cleansing and condltioning the hair. Therefore, it would be highly desirable to develop effective, yet gentlel skin cteansing compositions which would also provide a skin moisturizing benefit.
It is therefore an object of the present invention to provide improved personal cleansing compositions which thoroughly cleanse the skin and which also moisturize the skin, i.e. to provide combined skin cleansing and moisturizing compositions.
It is a further object of the present ~nvention to provide combined cleansing and moisturizing compositions whish are very mild to ~he skin and occular mucosae.
It is an even further object of the present invention to provide combined cleansing and molsturizing compositions which will produce a foam which is abundant, stab1e, and of high qu~l~ty.
It is a still further object of the present invention to provide methods for~cleansing and mo~sturizing the skin.
It is la ~et further ~object of the present invcntion to provide methods for delivering combined cleansing and moisturizing compositions as foams.
35~ These and other object;s wil1 become readily apparent from the detailed description~which follows.
