Definitions

  • the present invention relates to a foaming agent comprising at least a polyoxyethylene and/or polyoxypropylene type of nonionic surfactant which has a total HLB by Griffin method of at least 12, which provides clear and stable concentrates and voluminous and stable foaming, and smooth and mild touch to foaming cosmetic compositions, with improved less flaking tendency.
  • the present invention relates to leave-on hair mousse products comprising this foaming agent.
  • Cosmetic compositions such as shaving creams, hair mousses, spray foams, foaming lotions and foaming creams are aimed to be dispensed or sprayed as foams and applied on the human skin or hair. These products are described in the present invention as "leave-on foaming cosmetic products”.
  • One common characteristic desired for these leave-on foaming cosmetic products is a foam having favorable characteristics to the consumer such as voluminous and stable foaming, with smooth and mild touch to the skin and hair.
  • Hair mousses Leave-on foaming cosmetic compositions for hair are usually referred to as "mousses", which term will be used in the present invention. Hair mousses were born in Europe in the early 1980s. Hair mousses are fundamentally an aerosol foam, however, non-aerosol foams are also known. The general appeal of hair mousses can be largely attributed to the ease of application and controlled amount of product which are possible from mousse formulations. Hair mousse compositions are generally dispensed by a compressible dispenser or a valve and applied to the user's hand or a specifically designed comb and spread through the hair. Alternatively, hair mousse compositions can be directly applied to the hair by dispensing through nozzles. Hair mousses are formulated for the purpose of styling, setting, and arranging, or for other purposes such as shampooing, conditioning, treating, dyeing, and combinations thereof.
  • alcohol refers to volatile primary alcohols having about 1 to 6 carbons, particularly ethanol. Alcohol is used in mousses for a number of reasons. First, the presence of volatile alcohol can aid styling by decreasing drying time. However, it is assumed that this drying has raised the concerns of some consumers that alcohol is also drying hair. Second, alcohol aids foam breakage as the mousse is spread throughout the hair. It is known that foam breakage is a result of the ability of alcohol to act as a defoaming agent. Third, alcohol itself improves product preservation.
  • alcohol enhances the compatibility of the concentrate with the propellant, and acts as a solubility bridge between the resin and the water base.
  • alcohol is a good solvent for dissolving oil base ingredients such as conditioning fatty alcohols. Consequently, elimination of alcohol from the formulation may affect product performance.
  • foaming agent which can be used in hair mousse compositions with or without alcohol.
  • Preservatives such as DMDM Hydantoin (dimethylol dimethyl hydantoin) and Kathon CG (mixture of methylchloro- isothiazolinone and methyl isothiazolinone) are known as effective preservatives at low levels, however, are not approved for use in leave-on cosmetic products in a number of countries. Phenoxyethanol and EDTA are widely accepted for use, however, are not satisfactorily effective at low levels.
  • Parabens such as methyl paraben, propyl paraben, butyl paraben, and LiquaPar oil (mixture of isobutyl paraben, isopropyl paraben, and butyl paraben) are also widely accepted for use.
  • parabens are lipophilic, they cannot dissolve in water, and thus have some formulation constraints.
  • Methyl paraben and propyl paraben are difficult to formulate at high levels, for they are solid at room temperature.
  • the type of propellents are also • known to affect product performance.
  • fluorohydrocarbons such as difluoroethane 152a (supplied by DuPont) can be used for a wide range of formulations.
  • Propane and dimethyl ether can also be used for a wide range of formulations.
  • propane is relatively combustible.
  • Dimethyl ether when used at high levels can be corrosive.
  • LPG liquefied petroleum gas
  • LPG is a relatively safe propellant, however, have some formulation constraints.
  • Evaluation of product performance for hair mousse compositions vary depending on the purpose and concept of the product. In evaluating the performance of a hair mousse, one generally considers properties seen in three major stages; the properties of the foam upon dispensing from the package, the properties of the foam upon applying to the hair, and properties of the end results to the hair. Properties considered upon dispensing include volume of foam and foam expansion speed. It is known that when foam expansion is slow or delayed, "pooling" of the product occurs. Properties considered upon applying to the hair include stability and breakability of the foam, non-soapiness, smoothness, softness, creaminess, and stickiness. Properties considered on the end results to the hair include style control, dry or wet feel of hair, washability, shine, moisturizing, conditioning, anti-static, and brushing.

Description

NONIONIC FOAMING AGENT FOR FOAMING COSMETIC COMPOSITIONS
TECHNICAL FIELD The present invention relates to a foaming agent comprising at least a polyoxyethylene and/or polyoxypropylene type of nonionic surfactant which has a total HLB by Griffin method of at least 12, which provides clear and stable concentrates and voluminous and stable foaming, and smooth and mild touch to foaming cosmetic compositions, with improved less flaking tendency. In particular, the present invention relates to leave-on hair mousse products comprising this foaming agent.
BACKGROUND
Cosmetic compositions such as shaving creams, hair mousses, spray foams, foaming lotions and foaming creams are aimed to be dispensed or sprayed as foams and applied on the human skin or hair. These products are described in the present invention as "leave-on foaming cosmetic products". One common characteristic desired for these leave-on foaming cosmetic products is a foam having favorable characteristics to the consumer such as voluminous and stable foaming, with smooth and mild touch to the skin and hair.
Leave-on foaming cosmetic compositions for hair are usually referred to as "mousses", which term will be used in the present invention. Hair mousses were born in Europe in the early 1980s. Hair mousses are fundamentally an aerosol foam, however, non-aerosol foams are also known. The general appeal of hair mousses can be largely attributed to the ease of application and controlled amount of product which are possible from mousse formulations. Hair mousse compositions are generally dispensed by a compressible dispenser or a valve and applied to the user's hand or a specifically designed comb and spread through the hair. Alternatively, hair mousse compositions can be directly applied to the hair by dispensing through nozzles. Hair mousses are formulated for the purpose of styling, setting, and arranging, or for other purposes such as shampooing, conditioning, treating, dyeing, and combinations thereof.
In recent years, some consumers have expressed a desire to have "alcohol-free" hair mousse products because of concerns relating to drying of the hair, or concerns of volatile solvents being emitted to the environment. In this context, alcohol refers to volatile primary alcohols having about 1 to 6 carbons, particularly ethanol. Alcohol is used in mousses for a number of reasons. First, the presence of volatile alcohol can aid styling by decreasing drying time. However, it is assumed that this drying has raised the concerns of some consumers that alcohol is also drying hair. Second, alcohol aids foam breakage as the mousse is spread throughout the hair. It is known that foam breakage is a result of the ability of alcohol to act as a defoaming agent. Third, alcohol itself improves product preservation. Fourth, alcohol enhances the compatibility of the concentrate with the propellant, and acts as a solubility bridge between the resin and the water base. Fifth, alcohol is a good solvent for dissolving oil base ingredients such as conditioning fatty alcohols. Consequently, elimination of alcohol from the formulation may affect product performance. Thus, there is a desire to provide a foaming agent which can be used in hair mousse compositions with or without alcohol.
The species and level of preservatives are also known to affect product performance. Preservatives such as DMDM Hydantoin (dimethylol dimethyl hydantoin) and Kathon CG (mixture of methylchloro- isothiazolinone and methyl isothiazolinone) are known as effective preservatives at low levels, however, are not approved for use in leave-on cosmetic products in a number of countries. Phenoxyethanol and EDTA are widely accepted for use, however, are not satisfactorily effective at low levels. Parabens such as methyl paraben, propyl paraben, butyl paraben, and LiquaPar oil (mixture of isobutyl paraben, isopropyl paraben, and butyl paraben) are also widely accepted for use. However, because parabens are lipophilic, they cannot dissolve in water, and thus have some formulation constraints. Methyl paraben and propyl paraben are difficult to formulate at high levels, for they are solid at room temperature. Thus, there is also a desire to provide a foaming agent which can be used in hair mousse compositions in combination with a wide range of preservatives. The type of propellents are also • known to affect product performance. It is known that fluorohydrocarbons such as difluoroethane 152a (supplied by DuPont) can be used for a wide range of formulations. Propane and dimethyl ether can also be used for a wide range of formulations. However, propane is relatively combustible. Dimethyl ether when used at high levels can be corrosive. LPG (liquefied petroleum gas) is a mixture of mainly iso-butane, n-butane, and propane, and is available in different pressure grades. LPG is a relatively safe propellant, however, have some formulation constraints. Thus, there is also a desire to provide a foaming agent which can be used in hair mousse compositions in combination with a wide range of propellents.
Evaluation of product performance for hair mousse compositions vary depending on the purpose and concept of the product. In evaluating the performance of a hair mousse, one generally considers properties seen in three major stages; the properties of the foam upon dispensing from the package, the properties of the foam upon applying to the hair, and properties of the end results to the hair. Properties considered upon dispensing include volume of foam and foam expansion speed. It is known that when foam expansion is slow or delayed, "pooling" of the product occurs. Properties considered upon applying to the hair include stability and breakability of the foam, non-soapiness, smoothness, softness, creaminess, and stickiness. Properties considered on the end results to the hair include style control, dry or wet feel of hair, washability, shine, moisturizing, conditioning, anti-static, and brushing.
An attempt to achieve the above requirement, co-pending, commonly-assigned U.S. application serial number 08/154,231 (Y. Chen and T. Nambu) filed November 18, 1993 discloses a foaming agent for leave-on foaming cosmetic composition comprising an amphoteric surfactant and an amine oxide.
However there remains a need for foaming cosmetic compositions contain no amine oxide. In Europe, there is an interest in a formula that does not use amine oxide for safety reasons.
Further there remains a need for foaming cosmetic compositions having improved clear and stable concentrations, especially, in the presence of a polymer, such as cationic type of water soluble polymer in the compositions . OBJECT OF THE INVENTION

It is also an objective of the present invention to provide a foaming cosmetic composition which provides a stable and clear concentration for better product stability.
It is further an object of the present invention to provide a foaming cosmetic composition such as a hair mousse composition comprising said foaming agent which provides a foam having appropriate foam breakdown (foam breakability) under shear and is easy to spread on hair, has a smooth, soft and creamy texture, and has a mild touch.
It is further an object of the present invention to provide a foaming cosmetic composition such as a hair mousse composition comprising said foaming agent which can be formulated in combination with a wide range of solvents, preservatives, and propellants.
It is further an object of the present invention to use a surfactant system that does not contain amine oxide.
It is further an object of the present invention to provide a foaming cosmetic composition such as a hair mousse composition comprising said foaming agent which provides quick, voluminous foam expansion and reduced pooling upon dispensing.
It is further an object of the present invention to provide a hair mousse composition comprising said foaming agent which provides good style control, conditioning effect, and good feel to the hair, with less flaking tendency.

The compositions shown in Tables 1 , 2 and 3 can be prepared by any conventional method well known in the art. A suitable method is as follows: Polymers and preservatives are added into distilled water under agitation at room temperature. The obtained mixture is heated up to 70-75°C until homogenized. Other optional components are added to the heated mixture, and agitated until homogenized. The obtained mixture is allowed to cool to 30-40°C, and surfactants, perfume and other heat sensitive components are added. The obtained concentrate is packed into cans with propellant.
Evaluation of the Product of the Present Invention
Evaluation of a composition of the present invention has been done according to the following two methods by using the following test products (compositions A and B):
1. Test products:
(The formulations of the following test products are shown in Table 3.)
Composition A: A mousse composition which is an example of the composition of co-pending U. S. application Serial No. 08/154231.
Composition B: A mousse composition which is an example of the present invention.
(1 ) FLAKING TENDENCY TEST
Method:
Prepare black, straight flat hair switches (Oriental-hair switches), total 10 gram weight per switch, with 7 cm width and 25 cm length. Hang the each hair switch upright on a stand, under room temperature condition. Weight 1.5 gram of mousse foam of the test products (A and B). Carefully spread out the foam on the surface of one side of switch, without letting the foam collapsing off while applying. Uniformly spread all 1.5 gram across whole hair switch and let the foam dry on switches naturally. After foam disappear and dry, grade the residue tendency using the following scale.
Scale: 0: Nothing visual. (Same as Virgin hair)
Scale 1 : Slight residue.
Scale 2: Moderate residue.
Scale 3: Severe residue. (Same as Virgin hair)
Scale 4: Very severe residue.
The results of 10 expert panelists evaluation showed: Composition A: Scale 3.0 Composition B: Scale 0.8
Namely, composition B showed significantly less flaking tendency than composition A.
(2) TEST FOR CLEARNESS OF CONCENTRATES
Method:
Put 5g concentrates into a 100 ml glass jar (diameter: 4 cm, height: 10 cm). Ask 10 panelists to rate the clearness of the concentrates based on the following scales:
0: Extremely clear.
1 : Very clear
2: Clear
3: Not so clear/not so cloudy.
4: Cloudy
5: Very cloudy
6: Extremely cloudy.
The results of 10 panelists evaluation showed: composition A: average score is 4.6, Standard Deviation is 0.84. composition B: average score is 1.2, standard deviation is 0.79.
Namely, the calculation of SD showed these results are significantly different. In other words, composition A is significantly clearer than composition B.
