Problems solved by technology

However, it is difficult to formulate personal care compositions with increased levels of olfactory compositions
As the level of olfactory composition increases, physical stability decreases, which can affect the final product appearance and distribution of olfactory composition in personal care compositions

Embodiment

[0118] Examples C-F contain C72, a microcrystalline wax exhibiting a penetration of about 35 dmm to about 75 dmm at 25°C. When 5% (Example C) and 10% (Example D) When C72 was added to the composition, the firmness parameters increased to acceptable levels and the instability index decreased compared to the 2x control, while the mean vapor release remained similar to the 2x control. Although hardening the composition, the addition of microcrystalline wax in Examples C and D did not prevent vapor release. However, at about 20% and 30% as in Examples E and F, respectively At C72, the firmness parameter increased to over 238 g.sec and the average vapor release at 8 hours decreased to a level significantly lower than the 2x control.

[0119] Examples G and H contain X-145 AH, a second microcrystalline wax exhibiting a needle penetration of about 35 dmm to about 75 dmm at 25°C. When 5% (Example G) and 10% (Example H) When X-145AH was added to the composition, the firmness...

Embodiment A-B

[0134] Examples A-B were prepared according to the following procedure:

[0135] First, place the water bath ( Werke LT6( Wilmington, NC) or equivalent) connected to the main reaction vessel ( Werke LR-2000V Lab Reactor or equivalent) and set the water bath to 60.0°C. Measure petroleum jelly and transfer it to the main reaction vessel using a spatula. Reweigh the petroleum jelly to ensure accurate addition. Then, lower the lid and set the stirrer to 60 RPM. The vessel was heated to a jacket set point temperature of 60.0°C (corresponding to a reaction vessel temperature of 60°C ± 1°C) until the mixture was completely melted.

[0136] While mixing in the main reaction vessel, a premix of olfactory agents was prepared. First, camphor and thymol were added to a premix beaker. Grind the menthol crystals with a pestle and mortar and add to the premix beaker. Add turpentine, eucalyptus, and cedar wood oil to the premix beaker in sequence. Insert a magnetic stir bar into...

Embodiment W-X

[0158] Examples W-X were prepared according to the following procedure

[0159] First, place the water bath ( Werke LT6( Wilmington, NC) or equivalent) connected to the main reaction vessel ( Werke LR-2000V Lab Reactor or equivalent) and set the water bath to 85.0°C. Measure petroleum jelly and add-on wax and transfer them to the main reaction vessel using a spatula. Reweigh the petroleum jelly and add-on wax to ensure accurate addition. Then, lower the lid and set the stirrer to 60 RPM. The vessel was heated to a jacket set point temperature of 85.0°C (corresponding to a reaction vessel temperature of 85°C ± 1°C) until the mixture was completely melted.

[0160] On a separate hot plate, add EB-21, GP-1, and 3-methyl-1,3-butanediol to a second container and stir to induce a vortex. The mixture was heated to 95°C-100°C while stirring using a magnetic stir bar until completely transparent with no visible particles to form a gelling agent mixture.

[0161] When both...

Abstract

Provided herein is a personal care composition that can exhibit an increased vapor release while maintaining physical stability and texture. The personal care composition can contain from about 35% to about 90% petrolatum, from about 20% to about 50% of an olfactory composition, and a gelling agent mixture. The gelling agent mixture can contain dibutyl lauroyl glutamide, dibutyl ethylhexanoyl glutamide, and a solvent selected from the group consisting of pentylene glycol, propylene glycol, hexylene glycol, 3-methyl-1,3-butanediol, 3-methyl-1,2-butanediol, 1,5-pentanediol, and combinations thereof. The personal care composition can exhibit a vapor release of from about 35 mg to about 300 mg at 8 hours and can have an Instability Index of less than about 0.8.

Description

technical field [0001] Described herein is a personal care composition, and more particularly a petrolatum-based personal care composition comprising an olfactory composition and a gelling agent mixture, wherein the personal care composition exhibits increased vapor release while maintaining physical stability and texture. Background technique [0002] Consumers apply personal care compositions to the chest, back and / or throat on a daily basis to relieve nasal congestion, dry cough, chest congestion, muscle aches and / or pains, and sleep difficulties caused by colds and / or flu. The olfactory composition may be delivered from the personal care composition as a vapor which is inhaled through the nose and which provides a cooling and soothing sensation. However, some consumers find that current product strengths are insufficient to provide desired levels of symptom relief. It has been found that products that provide a stronger sensory experience and smell are perceived by con...
