The present invention provides personal wash compositions where hydrogenated triglyceride oils (defined by IV of 0 to &#x3c;20) are specifically formulated to provide low temperature stability. Specifically when formulated to have specific concentration of hydrogenated triglycerides, delivered as pure sample or from mixtures of hydrogenated and other triglyceride oils, desirable low temperature stability of formulations is achieved.

Stable liquid cleansing compositions comprising critical window of hydrogenated triglyceride oils

The present invention provides personal wash compositions where partially hydrogenated triglyceride oil (defined by IV of 20 to 100) are specifically formulated to provide low temperature stability. Specifically when formulated to have specific concentration of partially hydrogenated triglycerides, delivered alone or as part of mixture with other oils, desirable low temperature stability of formulations is achieved.

Stable liquid cleansing compositions comprising critical window of partially hydrogenated triglyceride oil of defined iodine value

The present invention relates to super mild surfactant systems used in combination with skin or hair benefit agent(s). Specifically, surfactant systems comprise a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product to provide synergy which reduces irritation (as measured by Patch Testing) so greatly that it is comparable to mildness which normally can be only achieved using very great amounts of benefit agent (e.g., emollient). Use of benefit agent reduces irritation even further.

Personal wash cleanser comprising defined alkanoyl compounds, defined fatty acyl isethionate surfactant product and skin or hair benefit agent

The present invention relates to liquid personal care composition comprising both low levels of specific fatty isethionate product (e.g., less than 4%) and low overall fatty acid content (less than 4%) which, quite surprisingly, maintain excellent foaming profile relative to identical composition having high overall fatty acid content.

Mild, foaming liquid cleansers comprising low levels of fatty isethionate product and low total fatty acid and/or fatty acid soap content

The invention provides liquid cleanser compositions which can use fatty acyl isethionates surfactant products, regardless of free fatty acid and/or fatty acid salt content of isethionate mixture or chain length distribution of isethionates mixture. The key is to insure a specific combination of liquid crystal inducer (of surfactant phase) and of modifier so that the isethionates will be stable at low and high temperatures.

Stable liquid cleansing compositions comprising fatty acyl isethionate surfactant products with high fatty acid content

The invention provides liquid cleanser compositions which can use fatty acyl isethionates mixtures, regardless of free fatty acid content of isethionates mixture or chain length distribution of isethionates mixture. The key is to ensure a specific combination of liquid crystal inducer (of surfactant phase) and of modifier so that the isethionates will be stable at low and high temperatures.

Stable liquid cleansing compositions which may be prepared using fatty acyl isethionate surfactants

The invention provides a method for providing a stable liquid cleanser compositions which can use fatty acyl isethionates mixtures, regardless of free fatty acid contact of isethionates mixture or chain length distribution of isethionates mixture. The key is to insure a specific combination of liquid crystal inducer (of surfactant phase) and of modifier (to ensure large size domain providing stability) so that the isethionates will be stable at low and high temperatures.

Method of providing stability for liquid cleansing compositions comprising selection fatty acyl isethionate surfactants

An ordered liquid crystalline phase cleansing composition is disclosed that contains particles with a structure comprising a benefit agent and a gellation agent and provides high foaming with in a preferred embodiment levels of free emollient equal to or in excess of the level of surfactant. A method of depositing a benefit agent to the skin or hair with the ordered liquid crystalline phase cleansing composition is also disclosed.

Ordered liquid crystalline cleansing composition with benefit agent particles

An aqueous isotropic liquid cleansing and moisturizing composition is provided having a surfactant; a thickening agent, and organogel particles with a structure comprising a benefit agent and a gellation agent. In a preferred embodiment the inventive cleansing composition includes a free emollient having a weight average emollient particle size in the range about 1 to about 500 microns.

Isotropic cleansing composition with benefit agent particles

The present invention relates to lamellar phase compositions comprising dned surfactant systems and a structurant selected from the group consisting of liquid fatty acids liquid alcohols and derivatives thereof which structurant is responsible for inducing the lamellar phrase.
