[0002] Shaving foam containing fragrances

[0003] The present invention relates to cosmetic products containing α-terpinene (INGI: Alpha-Terpinene).

[0004] A person's outward appearance can be influenced and enhanced through the use of cosmetic products. Regular use of cleansing and care products ensures that people feel attractive, beautiful, and comfortable in their surroundings, and radiate this outwards.

[0005] Maintaining one's appearance includes not only skincare but also body hair care. In particular, the removal of body hair, especially facial hair, contributes to one's overall look. The term "shaving" refers specifically to the cutting of body hair directly at the skin's surface. Shaving practices can be influenced by fashion and cultural preferences. Often, facial hair removal is desired only in certain areas. Furthermore, shaving plays a significant role in hair removal on other parts of the body besides facial hair. It is common practice to remove hair from the legs, underarms, and / or pubic area.

[0006] The shaving process can be done wet or dry. In wet shaving, the hairs are softened before being cut by the razor blade. This minimizes the effort required and prevents unpleasant pulling. Softening the hairs means they absorb water, but first the outer sebum layer of the hair must be removed. Shaving aids are used for this process. These aids come in the form of shaving soaps, creams, gels, or foams. In addition to softening the hairs, shaving aids also care for the shaved skin, allow the razor blade to glide more smoothly, and ensure that the cut hairs are easily removed from the skin.

[0007] Shaving foams, in particular, are considered one of the most popular shaving aids among customers for preparing their hair before shaving. The foam is easy to dispense and can be applied directly to the area to be shaved. This makes application simpler than with products that first need to be lathered manually. Furthermore, customers associate the application of shaving foam with a pleasant feeling on the skin. It is also advantageous for customers to be able to apply the same foam consistency every time, making it easier to guide the razor blade during the subsequent shaving routine.

[0008] Furthermore, the application of shaving foam as a shaving aid also fulfills functions related to the care of the shaved skin. The addition of active and / or conditioning agents moisturizes the skin, leading to less post-shave irritation. In addition, shaving foams improve the glide of razor blades, which are usually made of stainless steel, on the skin, thus protecting it from shaving cuts.

[0009] Furthermore, it is of great importance that shaving aids, especially shaving foams, exhibit high surface adhesion. Firstly, the cosmetic product should adhere to the skin, preparing the hair and ensuring smooth gliding of the razor blade. Secondly, good adhesion to the skin surface ensures even distribution of the product on the skin being shaved. It is also crucial that the cosmetic product adheres well to metal surfaces, as this ensures that the shaving aid can be easily removed from the skin when using a metal razor blade. The removed shaving aid also carries away the cut hairs. In general, this improves the ease of removal of the shaving aid when using a razor blade, resulting in a more comfortable shaving experience for the user.Metal adhesion is measured in mass per area (g * cm). -2 The metal adhesion is specified and can be determined by measurements with a metal spatula. A cosmetic product with high metal adhesion exhibits a metal adhesion of 30 to 50 mg per cm². 2 on.

[0010] Consumers continue to prefer cosmetic shaving products that produce a stable lather. The stability of shaving foams describes how well and for how long the foam retains its shape and consistency after application. A stable foam is important so that the user can prepare the skin for shaving with an even layer. The foam's stability helps to lift the hairs and prepare them for the cut, resulting in a closer shave. Good stability is characterized by a thick, creamy foam that remains stable throughout the shave. Furthermore, a foam with greater stability provides a more pleasant feel on the skin.

[0011] The stability and adhesion of cosmetic foams to surfaces depend on the amount of surfactants used in the formulation. It is important to avoid increasing the proportion of surfactants in cosmetic products, especially cosmetic foams, as this could lead to reduced gentleness, skin irritation, and redness. This is particularly important to avoid with shaving products, since the use of razor blades already puts increased stress on the skin. Therefore, there is a need for cosmetic products, especially shaving products, that produce a stable foam when used conventionally and adhere particularly well to metal surfaces, without increasing the surfactant content.

[0012] Therefore, the object of the present invention was to provide cosmetic products which can be released from a packaging material as a stable foam.

[0013] Another objective of the invention was to provide cosmetic products that exhibit increased metal adhesion.

[0014] Conventional cosmetic shaving aids are known, among other things, from EP 1992323 A1. However, the disclosed preparations could not provide any indication of the present invention.

[0015] Surprisingly for those skilled in the art, it has now been found that the problem of metal adhesion arising in a foamed cosmetic product could be solved by the present invention.

[0016] The present invention relates to a cosmetic product comprising a) a pressure vessel with a dispensing valve b) a cosmetic preparation comprising i. an O / W emulsion comprising alpha-terpinene ii. at least one propellant that foams and / or dispenses the O / W emulsion.

[0017] A further object of the invention is an aerosol can with a dispensing valve containing the cosmetic product according to the invention. A further object of the invention is the use of the cosmetic product according to the invention to provide a foam for application to the skin.

[0018] Another aspect of the invention is the use of the cosmetic product according to the invention for providing a shaving foam. When such a foam is used as shaving foam, it exhibits particularly good metal adhesion. Therefore, such foams provide a more pleasant shaving experience.

[0019] Another object of the invention is a method for applying the cosmetic product according to the invention, characterized in that in a first step the cosmetic preparation is removed from the pressure vessel, in a second step the cosmetic product is applied to the skin moistened with water, and in a third step the hairs in the area of ​​the skin where the cosmetic product has been applied are shaved with a metal razor blade.

[0020] Surprisingly, the combination of the invention, or rather the cosmetic product according to the invention, exhibited increased adhesion to metal, which was determined by measuring metal adhesion. Consequently, a creamy foam with good stability could surprisingly be built up in a conventional application without increasing the content of surfactants or emulsifiers.

[0021] Any metal adhesion values ​​given in this disclosure refer to measurements taken under standard conditions. For the measurement, the pressure vessel was first shaken and the cosmetic product thoroughly mixed. The cosmetic product was then dispensed via the dispensing valve, and the aerosol foam or foamed cosmetic preparation was placed on a scale (5 g of aerosol foam per measurement). To determine the metal adhesion, a metal spatula (stainless steel, 1.5 cm x 1.5 cm) was immersed in the aerosol foam or foamed cosmetic preparation for 2 seconds and then withdrawn. The metal adhesion of the cosmetic product was determined from the difference in the foam weight before and after immersion and withdrawal of the spatula.

[0022] Where weight percentages (wt%) are given below without reference to a specific composition or mixture, these percentages always refer to the total weight of the cosmetic preparation. Where ratios of components / substances / groups of substances are disclosed below, these ratios refer to the weight ratios of the components / substances / groups of substances mentioned.

[0023] The terms “according to the invention”, “advantageous according to the invention”, “advantageous in the sense of the present invention”, etc., always refer within the scope of the present disclosure to the preparation according to the invention, the use according to the invention and the method according to the invention.

[0024] Unless otherwise stated, all tests were conducted under standard conditions. "Standard conditions" means 20°C, 1013 hPa, and a relative humidity of 50%.

[0025] When the term skin is used, it preferably refers to human skin.
