Abstract

The present invention is a single kit comprising at least one first cosmetic composition and one second cosmetic composition, wherein the first cosmetic composition is a polar formulation. The present invention relates to a kit in which the second cosmetic composition is a nonpolar formulation, and a method of beauty care using the kit. The invention also relates to a solid support having a multifunctional surface.

Description

  The present invention relates to the field of cosmetic compositions applied on solid supports for delivering cosmetic care to a subject in need thereof.

  The present invention more particularly relates to a single kit comprising at least one first cosmetic composition and one second cosmetic composition, a solid support having a plurality of functional surfaces, And methods for preparing them. The present invention relates to a method of beauty care, and more particularly to beauty complex care. These compositions are applied onto separate target zones of the keratinous material of interest, but they are in a spatially close relationship.

  Cosmetic compositions are combined with substrates such as nonwovens, paper or polymer films to enhance their functionality as well as to provide new sensory experiences to consumers. Wipes, facial masks and pads are typical examples of such combination products. Generally, the substrate is impregnated with one cosmetic composition and packaged for sale. The functionality of these products depends largely on the functionality of the cosmetic composition, more directly on the active ingredients used in the cosmetic composition, for example cleansing, makeup Up removal and refreshing are targeted in wipes, while in facial masks moisturizing, whitening and anti-aging are generally targeted.

  Since the keratinous structure of the integument system varies from region to region of interest, the care required for these different regions is different. Thus, there is a need to develop methods or processes where different areas can be treated simultaneously depending on the specific care benefits for each particular area. More specifically, because the lipid-protein structure of the face varies from region to region, the nourishment required for different regions of the face is based on what type of reward is required. Is different. Therefore, there is a need to develop methods or processes that allow different areas of the face to be treated simultaneously with a specific skin care composition for skin benefits for that specific area.

  It is very clear that different topical cosmetic compositions are applied over the required area, but for the consumer, he owns several separate cosmetic compositions and puts them in different areas in appropriate amounts. It is not convenient to apply. Thus, there is a need for a single product composed of composite cosmetic compositions and carriers for them.

Although methods of absorbing composite cosmetic compositions have already been taught in the prior art, the problem of limiting the interaction of multiple cosmetic compositions with each other is not addressed. An undesirable mutual interference that one cosmetic composition has a spatially close relationship with the other cosmetic composition in the substrate is at least
1.Decrease in activity of active ingredients
2. Clearly leads to delivery of the active ingredient to unwanted / unwanted areas.

  There is a need to develop such a single product that resists the interaction between cosmetic compositions embedded on a single substrate.

Indian patent application number 2215 / DEL / 2013

ICI Americas Inc, The HLB system: A time saving guide to emulsifier selection, Chapters 1 and 2 C.T.F.A.Cosmetic Ingredient Dictionary and Handbook November 30, 2009, European Parliament and Council, EC Regulation N ° 1223/2009 ISO standard 9092

  The present invention aims to provide a solution to the problems listed above.

  More particularly, the present invention aims to provide a more convenient way for consumers to apply several separate cosmetic compositions, preferably in appropriate amounts, to different areas. The present invention also provides active ingredients delivered to undesired / undesired areas of the subject keratin material in cases where multiple cosmetic compositions are applied to multiple areas via a single product or device It is also intended to limit this. The present invention is also aimed at limiting the possibility that the activity of an active ingredient will be reduced in cases where multiple cosmetic compositions are applied to multiple areas via a single product or device. More generally, the present invention overcomes the problems associated with the interaction of multiple cosmetic compositions in the case of applying multiple cosmetic compositions to multiple areas via a single product or device. With the goal.

  In the case of applying a plurality of cosmetic compositions to a plurality of skin areas via a single product or device, the present inventors have the problem that when the viscosity of the composition is increased, the plurality of cosmetic compositions overlap. Confirmed that can be controlled. Increasing the viscosity of the composition in this way restricts the delivery of the active substance from the substrate to the skin, thereby correcting its effectiveness. Furthermore, increasing the viscosity of the cosmetic composition impairs the sensory profile, which is unacceptable to consumers in substrate-based products. Accordingly, the present invention is further aimed at overcoming the technical problem of impaired sensory profiles caused by such products while overcoming the other problems listed above.

  This innovation addresses the solutions to the challenges listed above by providing an innovative approach.

  Surprisingly, by controlling the polarity (hydrophilic or lipophilic properties) of the two compositions, the composition of multiple compositions on a single substrate can be obtained without increasing the viscosity of the composition. It has been found that the overlap is limited.

  Polarity relates herein to the HLB of a formulation, calculated by using standard HLB equations (Griffin method). As used herein, nonpolar formulations exhibit an HLB of 4-9, while polar formulations exhibit an HLB value of 10-16.

  The present invention more particularly relates to at least one first cosmetic composition and at least one first composition on a single solid support for providing cosmetic care, preferably complex cosmetic care. A combination with, or use in, a combination of two cosmetic compositions, wherein the first cosmetic composition is a polar formulation and the second cosmetic composition is a non-polar formulation Or in combination. The solid support is defined to be a manufactured product or device, not the target encapsulation system. The support is applied over at least a part of the target encapsulation system, in particular for applying the cosmetic composition onto a part of the encapsulation system, or of the encapsulation system. Suitable for contacting part.
