Patent Application
20140301965
The present invention generally relates to cosmetics, and more particularly relates to a cleaning agent including in a cosmetically acceptable carrier at least one anionic surfactant, at least one amphoteric and/or zwitterionic surfactant, at least one silicone and at least one cationic polymer.
Cosmetic cleaning agents, such as for example hair shampoos, are based on conventional anionic, amphoteric, zwitterionic, non-ionic and/or cationic surfactants.
Owing to their outstanding cleaning and foaming ability, anionic surfactants, optionally mixed with small amounts of co-surfactants, are predominantly used.
Such a commercial shampoo cleans the hair and removes sebaceous residues and/or residues of styling agents and other impurities from the surface of the hair and from the scalp.
However, the cleaning process also removes lipids and proteins from the hair and scalp, which can damage the hair structure and cause the scalp to dry out, particularly with frequent cleaning.
To eliminate these disadvantages, surfactants which are gentle and well tolerated have preferably been used in hair cleaning agents in recent years.
Although surfactants that are gentle per se are known, they do not yet satisfy all consumer requirements to an adequate degree.
Thus gentle surfactants are often not highly foaming and reduce the amount and quality of foam (creaminess and fine-pored nature of the foam). The incorporation of care substances into hair cleaning agents can further reinforce this effect.
Finally, sensory hair quality plays a prominent role among consumers with regard to acceptance of a shampoo.
Along with cleaning performance, the feel of the hair after washing, in both the wet and dry state, determines the satisfaction of a consumer with a cosmetic hair cleaning agent.
The critical factor in this perception is the sense of care, which can be described in particular by the feel, the combability, the shine and the softness of the hair. Furthermore, the hair should not appear heavy, nor should it be electrostatically charged.
There is therefore still a demand for active agents or for combinations of active agents for cosmetic cleaning preparations having good caring properties, an advantageous rheology profile and good foam properties.
It is therefore desirable to provide balanced, caring cleaning agents having good foam quality.
The cleaning agents should be suitable in particular for the gentle cleaning and care of the hair, and after application they should impart an improved combability and increased shine to the hair.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this background of the invention.
It was found that cleaning agents based on anionic and special amphoteric/zwitterionic surfactants and on cationic polymers and silicones are outstandingly suitable. The corresponding cleaning agents care for and clean the hair and in combination with water form a creamy, fine-pored foam.
A cosmetic cleaning agent according to the present invention includes, in a cosmetically acceptable carrier, a) at least one anionic surfactant; b) at least one amphoteric and/or zwitterionic surfactant of the following formula (I)
in which R denotes a straight-chain or branched, saturated or mono- or polyunsaturated alkyl or alkenyl residue having 8 to 24 carbon atoms, and R1 and R2 independently of one another denote the groups —(CH2)n—COOX, —(CH2)n—O—(CH2)n—COOX or —(CH2)n—OH, wherein n is an integer from 1 to 4 and X is an alkali, an alkaline-earth, an ammonium or an alkanolamine ion; c) at least one silicone of the following formula (II)
in which the residue R denotes a hydrogen atom, an alkyl group having 1 to 12 C atoms, an alkoxy group having 1 to 12 C atoms or a hydroxyl group, x denotes a number from 1 to 100, preferably from 20 to 30, y denotes a number from 1 to 20, preferably from 2 to 10, and a and b independently of one another denote numbers from 0 to 50, preferably from 10 to 30; and d) at least one cationic polymer selected from quaternized cellulose derivatives.
