Description

[Detailed description of the invention] Foaming personal cleansing products with foam-boosting polymers Technical field The present invention is a personal cleansing agent for personal cleaning, especially facial personal cleaning. Regarding the composition.

Background technique Liquid and solid bar based on soaps and/or synthetic surfactants ) compositions are commonly used to cleanse the human body. Proper foam when diluted with water In order to achieve Requires agent. This excess surfactant can irritate the skin and is unnecessary. In short, it can be put into the environment. Use of foam to cleanse the skin usually without rinsing It has been destined for new products used in For example, published on June 8, 1976, Viola U.S. Pat. No. 3,962,150 (incorporated herein by reference) reference. Mild reactions that can result from the use of such products for general cleaning Awareness of the environmental benefits and environmental benefits was minimal or nonexistent. good skin The amount of surfactant actually required to provide adequate cleaning is quite small and Most detergent surfactants in regular cosmetic solids leave stains on the solids holder. Detergent surfactants that are rinsed off without benefit because they do not dissolve well or do not dissolve well. Wasted either in sex drugs. When using mechanical foaming equipment, a small amount of interfacial Active agents can be used to achieve proper foaming. However, surfactant When the amount of agent is minimized, the foam quality also decreases and the foam quality is reduced by the quality of the cosmetic solids. The present invention has a quality worse than that of a small amount, e.g. 1% to about 16% detergent surfactant, preferably a mild detergent surfactant and Liquid Person containing a small amount of roam enhancing polymer cleansing products (compositions), which are manipulated by individuals to produce foam; Packaged in a container that can be used to produce products (squeeze foamer container)] . The compositions of the invention preferably have minimal adverse effects on both the skin and the environment. It has a very low content of detergent surfactants. The quality of the foam is amazing. In addition, the ability to dispense the product can be improved by increasing the viscosity by adding small amounts of polymers. It can be increased without any negative effect on power. Foam quality and viscosity are thus It is quite surprising that they are closely related. Only very small differences in viscosity required to make a substantial difference in foam quality.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention provides (1) a detergent surfactant, preferably a mild detergent surfactant with 0. 1% to about 16%, preferably about 1% to about 8%, more preferably about 2% to about 6%; and (2) a foam-enhancing polymer from about 0.01% to about 5%, preferably from about 0.04% to about 2% of a methyl cleansing composition in the form of an aqueous liquid.

"Delta viscosity" refers to the viscosity of a composition having a viscosity-increasing polymer and the viscosity-increasing polymer. is the difference between the viscosity of a composition with and without. The foam-boosting polymer has at least about 1 centipoise, preferably about 2 to about 10 centipoise, more preferably about This causes an increase in the viscosity of the composition (without polymer) by 2 to about 5 centipoise. sticky The increase in degree of foaminess is determined by the Foam Rating (Fo am Creamy Feel Rating), therefore increasing the The dampness rating is at least about 0.5, preferably at least about 1C, and more. Preferably it is raised by at least 2. In other words, the composition foam without polymer The ream feeling rating is at least 0.5 lower than the composition with the polymer.

The composition of the invention preferably comprises Brookfield L with UL adapter. Viscosity at 21°C when measured using a VT viscometer is at least about 1,5, preferably is about 2 to about 15, more preferably about 2 to about 12, even more preferably about 3 to about 10 Has centipoise. The lower viscosity limit is set by the quality of the foam and it Varies depending on activator system. Generally, the upper viscosity limit is as long as the product can be easily dispensed. , as high as possible. Thus, viscosities of 20°30 and even 40 cps are suitable for the present invention. Included within the scope. More preferred compositions have from about 1 to about 5 cps without polymer. Prepared from formulations with viscosities within the range. The composition of the present invention preferably has the following properties: Bubble creaminess rating as defined below at least about 5, preferably about or about 6 has. A foam rating of about 7 or higher is also desirable for some products.

Squeeze foam compositions without polymers contain a large amount of surfactant, 10-25%, preferably or can be formulated using 15-20% and achieve a foaming feeling rating of 6.7 or 8. to be accomplished.

Compared to personal cleansing compositions that are in the form of cosmetic solids, the compositions of the present invention Things are extremely mild.

Using less detergent surfactant makes detergent surfactant milder and The use of squeeze foamer packaging is more aggressive due to the increased foam Makes the resulting foam more acceptable to consumers without the need to use detergent surfactants. let

From an environmental point of view, as previously discussed, the present invention uses less organic material. and by using fewer substances and not using propellants, the composition can be prepared simplifies the use of the concentrate by the final consumer for manufacturing.

This minimizes the need for continuous dispensing of the squeeze foam dispenser.

The compositions of the present invention contain about 60% to about 99% water, preferably at least 75% and at least 75% water. and trace amounts of other suitable solvents. More water and less organic matter desirable to minimize environmental problems.

Public notice on the 8th.

The packaging does not use propellants and is therefore consumer and environmentally friendly. It's safe. They create foam from almost any surfactant composition. single Although it is not necessary to add foam enhancers for the purpose of stabilizing the foam, Quality can be desirable. For some compositions, it may be necessary to ensure that the container operates properly. The use of foam enhancers can be counterproductive since the foam must be destroyed. There is even that. The composition is placed in a container reservoir (plastic squeeze bottle) Ru. Manually squeezing the container forces the composition into the foamer head or other foaming device. through which the composition is mixed with air, and then preferably to make the foam more uniform. Pass through a homogenizer to improve quality and control foam consistency. then , the foam exits as a uniform unpressurized aerated pond.

The minimum pressure to operate the squeeze former is about 1 psig, typically is about 2 psig to about 7 psig. The minimum pressure is It is proportional to the size of the channel, the viscosity of the composition, etc.
