The invention relates to an anti-dandruff shampoo comprising: &#x2014;a) from 0.1 to 5 wt. % of an anti-dandruff zinc salt; b) from 1 to 8 wt. % of an alkyl glycinate and/or alkyl carboxyglycinate; c) from 2 to 16 wt. % of an alkyl sulphate and/or an ethoxylated alkyl sulfate anionic surfactant; and, d) from 1 to 10 wt. % of a fatty acyl isethionate product which product comprises 40 to 80 wt. % fatty acyl isethionate and 15 to 50 wt. % free fatty acid and/or fatty acid salt and to the use of a surfactant system comprising components b) to d) to provide an improvement to the skin stratum corneum barrier.

Anti-dandruff shampoo

A personal care implement is disclosed having a water insoluble absorbent/adsorbent layer attached to a water insoluble scrubbing layer and a mild, low active, low viscosity cleansing composition contained in the absorbent/adsorbent layer. A sufficient quantity of the composition is transferred on demand to the scrubbing layer by squeezing the implement. The implement produces copious quantities of lather foam and mild cleansing.

Personal care implement with low active cleansing composition

A personal care cleansing composition is provided which includes a C-Cacyl glycinate salt and a dihydroxypropyl quaternary ammonium salt. Most preferred is sodium cocoyl glycinate in combination with dihydroxypropyl trimethyl ammonium chloride. The quaternary ammonium salt enhances foaming properties of the glycinate salt.

Foam enhancement of fatty acyl glycinate surfactants

A preservative system and a personal care composition containing that system is provided which includes the preservative combination of a C-Cacyl glycinate salt and a hydroxyethyl sulfonate salt. This preservative system is effective against gram negative bacteria, particularly

Preservative system and composition based on glycinate and hydroxyethyl sulfonate salt combination

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 super mild surfactant systems. Specifically, a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product 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 high amounts of benefit agent (e.g., emollient).

The present invention provides personal wash compositions where blends of triglyceride oils are specifically formulated to provide functional benefits. Specifically when formulated to have specific blend of saturated to unsaturated oils, perfect balance between, on the one hand, spreadability and deposition and, on the other hand, retention of excellent framing, is achieved.

Personal wash compositions comprising specific blends of saturated (hydrogenated) oil to unsaturated triglyceride oils

The invention provides a method of reducing surfactant damage in compositions comprising at least one surfactant and at least one benefit agent. The reduction in damage is measurable by decrease in number of protein binding sites in presence versus absence of benefit agent, or when benefit agent has solubility outside a defined range. The invention further relates to compositions comprising said surfactants and benefit agent(s) having reduced surfactant damage.

Method of reducing surfactant damage using compositions comprising benefit agents of defined high polarity

The invention provides a method selecting benefit agent(s) suitable for reducing surfactant damage in compositions comprising at least one surfactant and at least one benefit agent. The reduction in damage is measurable by decrease in number of protein binding sites in presence versus absence of benefit agent, or when benefit agent has solubility outside a defined range.

Method of selecting benefit agents/oils suitable for reducing surfactant damage

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 relates to compositions having enhanced post wash hydration by ensuring component or components of the composition meet selected defined criteria.

Dispersed particle compositions for enhancing post wash hydration comprising amphiphiles and moisturization additives of defined HLB

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

The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced deposition of hydrophilic benefit agents carried on, trapped within or in the presence of the structured benefit agent.

Personal product compositions comprising structured benefit agent premix or delivery vehicle and providing enhanced deposition of hydrophilic benefit agent
