Definitions
- a shampoo composition comprising at least one oligoester ammonium salt
- the present invention relates to shampoo compositions comprising at least one oligoester ammonium salt, methods of preparing the shampoo compositions, their use as well as methods of treating the hair.
- Natural oils have been used for centuries to condition human hair.
- Essential oils e.g. tea tree oil
- carrier oils e.g. jojoba oil
- Human hair contains about 97% of the protein keratin, which needs to be protected to preserve the strength and natural look.
- shampoos with hair conditioning properties can contain cationic components (e.g. surfactants) which are not washed out completely.
- cationic components e.g. surfactants
- the hydrophilic ends of the cationic components can bind to the keratin, whereas the hydrophobic ends of the molecules protect the hair surface.
- Modern hair conditioning shampoos compositions are often intended to soften the hair, to improve the gloss of hair and to avoid a greasy look of the hair.
- Silicone derivatives, and quaternary ammonium compounds (surfactants or polymers) which coat the cuticle of the hair were used as conditioning ingredients in shampoo compositions.
- Such shampoos can be made transparent or opaque.
- Hair shampoo compositions comprise generally one or more of the following types of ingredients (components):
- R 2 is C 11 -C 21 -alkyl
- R 3 is C 1 -C 4 -alkyl or hydroxyethyl
- n 1 to 7
- y is either 0 or 1
- [A ⁇ ] is halogen or methylsulfate.
- conditioning agent is proposed and the application of a micro-emulsion in hair conditioning is said to provide typical conditioning benefits, such as improved smoothness, softness and ease of combing wet hair.
- DE-C 19743687 discloses a detergent composition comprising ester ammonium salts of general formula (K),
- R 2 is C 1 -C 4 -alkyl
- R 3 is selected from C 1 -C 4 -alkyl or hydroxy-(C 1 -C 4 -alkyl);
- n 1 to 10;
- n1, n2, n3, n4 are from 0 to 4.
- composition in hair conditioning results in electrostatic charge reduction, ease of combing wet and dry hair, and improved softness. All of these effects are all typical for conditioning agents.
- Shine, gloss and surface smoothening are all desirable attributes in cosmetic compositions and preparations for personal care. For example, shine and gloss are highly desired attributes in nail color and hair care preparations. Surface smoothening is important in shampoos, hair conditioners and other hair treatment preparations and can provide superior (easier) wet and dry hair combing. However, such attributes can often only be attained by combining several different ingredients in the cosmetic compositions. Thus, there is still a great need in personal care for new compositions and/or components that deliver multiple effects at the same time, such as several of the aforementioned attributes and benefits. In particular there is a great need for providing such compositions and/or components that provide excellent performance as a shampoo and a wide variety of cosmetic benefits simultaneously.
- compositions comprising an ingredient that delivers at the same time multiple effects.
- the composition and its components can be prepared easily and provide or enhance several of the following benefits: hair detangling, improved wet and dry combing, shine (gloss) such as hair gloss without the need for silicone, conditioning, (hair) surface smoothening, hair repair, water resistance, film-forming properties, static charge reduction, anti-frizz, volume, thickening and surfactant activity.

Additionally, the HASE polymers include hydrophobic side groups, chains or blocks that give rise to associative interactions with each other, as well as with other hydrophobic species present in the compositions in which they are employed, for example, hydrophobic groups of surfactants, fatty acids, other thickening agents, and the like. Association creates hydrophobic regions distributed throughout the polymer chain network. This can also help to enhance the properties of the materials as solubilizing agents. Aculyn® 22 and Aculyn® 28 copolymers from Dow and Aqua SF-1® copolymer from Lubrizol Corporation are among the commonly used HASE materials. U.S. Pat. No.
