Description

Cosmetic product with low pilling effect Technical Field The present invention is in the field of cosmetics and relates to a cosmetic composition comprising at least one polyglycerol ester and polyglycerol. Background Cosmetic products are often used not only to make them look beautiful and attractive, but their effect also plays a decisive role in improving self-esteem and the sense of well-being of people. Accordingly, a variety of cosmetic products are used for daily cleaning and care of human skin. One well known group of cosmetic products are body lotions and facial care cosmetic products. These formulations are typically formulated as oil-in-water emulsions or in the form of gels. One experience that many consumers have with cosmetic body lotions and facial care products is that when the product is applied with a finger, the skin surface may appear as globules or small rolls. In many cases, this is described as a pilling effect. This is extremely frustrating for consumers because in many cases they must remove the pellets or roll to make the skin clean in appearance. In general, the occurrence of this pilling effect can be controlled by careful selection of the ingredients contained in the formulation. For example, it will be found that as the molecular weight of the polymers increases and as the amount of those polymers in the formulation increases, the pilling effect also increases. Powders like silica or starch may further increase the risk of pilling when used with those polymers. The most common polymers in body lotions and facial care cosmetic products are those formed by homo-or co-polymerization of acrylic acid, methacrylic acid and/or vinyl pyrrolidone. Because of their nature, they can be used at low molecular weights and typically only limited amounts of those polymers are needed to provide adequate rheological properties to the formulation. Furthermore, silicone oils and/or silicone derivatives provide a silky feel, which may also help reduce friction against the skin when the skin care product is applied. Silicone derivatives are considered to be chemical species containing [ R 1R2SiO]n subunit, where R 1 and R 2 are each alkyl groups, and n can be 1 or greater. Thus, in those formulations, the pilling effect can be conveniently controlled. However, for a variety of reasons, it may be desirable to provide formulations that are free of silicone and that polymerize in homo-or co-polymerized form of acrylic acid, methacrylic acid, and/or vinyl pyrrolidone. For example, the biodegradability of those compounds has not been sufficiently studied so that consumers do not want to use the products containing those ingredients. While this approach sounds simple, the problem of pilling is increasingly important for such formulations. In another aspect, prior art formulations typically comprise polyethylene glycol derivatives as emulsifiers, such as PEG-40 hydrogenated castor oil. Polyethylene glycol derivatives are considered to comprise at least one (-CH 2-CH2-O-)i unit) molecule, where i is an integer of 2 or greater, however, consumers prefer to use formulations that do not contain polyethylene glycol derivatives because they are concerned that these ingredients may cause unwanted side effects. Thus, it remains desirable to provide formulations and mechanisms that do not rely on the above ingredients to control and reduce pilling effects. Cosmetic compositions comprising polyglyceryl-3 methyl glucose distearate are disclosed in KR20050097587 a.
