Description

Hair Conditioning Composition Containing High Molecular Weight Ester Oil {HAIR CONDITIONING COMPOSITION COMPRISING HIGH MOLECULAR WEIGHT ESTER OIL}

Human hair is contaminated by contact with the environment and sebum secreted from the cuticle. Hair contamination can cause dirty, sticky feeling and unattractive appearance.

The shampoo cleanses the hair by removing excess dirt and sebum. However, shampoos can cause hair to get wet and entangled so that they are generally in an unrepairable condition. Once the hair is dry, it often becomes dry, rough, matty or curly due to the removal of the natural oils and other natural conditioning and moisturizing ingredients of the hair. In addition, the increased static electricity of the hair due to drying prevents the hair from sticking and results in a condition commonly referred to as "flying hair" or, in particular for long hair, an undesired phenomenon of "breaking off".

Various methods have been developed to alleviate the problem after the shampoo. These methods range from using hair conditioners such as products that are applied or rinsed after shampooing to hair conditioning shampoos that attempt to clean and condition together in a single product. Although some consumers prefer the availability and convenience of shampoos including conditioners, many consumers generally prefer the more conventional conditioner formulations that are used after the shampoo for hair separately from the shampoo.

The conditioning agent may be in the form of a rinsing or applying product and may be in the form of an emulsion, cream, gel, spray, and mousse. Such consumers, who prefer conventional conditioning agents, value the relatively high conditioning effect, or the convenience of adjusting the amount of conditioning depending on the condition of the hair or the part of the hair.

A common method of providing conditioning conditioning to hair is through the use of cationic surfactants and hair conditioning agents such as polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols.

Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair gloss, provide moisture, softness to hair and prevent static electricity. However, such constituents may also provide a feeling of sticking, stickiness or wax, especially when the hair is dry. Silicone conditioning agents are also known to provide conditioning features such as softness and ease of bonding due to the low surface tension of the silicone compounds. However, silicone conditioning agents can cause the hair to feel dry again or curly, especially when the hair is dry.

Based on the above, there remains a desire for hair conditioning compositions that provide improved conditioning features both when the hair is wet and when the hair is dry. Specifically, when the hair is dried, it is necessary to provide the hair with a long-lasting moist feeling, soft feel, and ease of care, without leaving a sticky feeling on the hair.

No prior art has provided all of the advantages and features of the present invention.

The present invention relates to hair conditioning compositions containing:

(1) a high molecular weight ester oil selected from the group consisting of water insoluble, having a molecular weight of at least about 800 and liquid at 25 ° C .:

a) pentaerythritol ester oil of the formula:

Wherein R ¹ , R ² , R ³ and R ⁴ are independently branched, straight chain, saturated or unsaturated alkyl, aryl and alkylaryl groups having 1 to about 30 carbon atoms;

References describing suitable nonvolatile dispersed silicone compounds are described in US Pat. No. 2,826,551 to Green; US Patent No. 3,964,500 to Drakoff, issued June 22, 1976; US Pat. No. 4,364,837 to Pader; And British Patent 849,433 to Woolston. "Silicon Compounds", distributed in 1984 by Petrarch Systems, Inc., provides an extensive list of suitable silicone compounds, although not exclusively.

Another nonvolatile dispersed silicone that may be particularly useful is silicone rubber. The term "silicone rubber" as used herein means a polyorganosiloxane material having a viscosity at 25 ° C. of at least 1,000,000 centistokes. The silicone rubber described herein may partially overlap with the silicone compound described above. This overlap is not intended to limit any of the materials. Silicone rubbers are disclosed by Petrarch and include US Patent No. 4,152,416 to Spitzer et al., Published May 1, 1979, and "Chemistry and Technology of Silicones" by Noll Walter, published by Acacemic Publishing, New York, 1968. do. General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76 also describe silicone rubber. A "silicone rubber" is typically one having a mass molecular weight of greater than about 200,000, generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, poly (dimethylsiloxane methylvinylsiloxane) copolymer, poly (dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.

Also useful are silicone resins that are highly crosslinked polymeric siloxanes. Crosslinking is introduced through the incorporation of tri- and tetra-functional silanes with mono- or bi- or silanes during the preparation of the silicone resin. As is well known in the art, the degree of crosslinking necessary to produce the silicone resin will vary depending on the particular silane units incorporated in the silicone resin. Generally, silicone materials are considered to be silicone resins that have a sufficient degree of trifunctional and tetrafunctional siloxane monomer units and thus have a sufficient level of crosslinking so that they dry to a hard or hard film. The ratio of oxygen atoms to silicon atoms is indicative of the degree of crosslinking in a particular silicone material. Silicone materials having at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen: silicon atoms is at least about 1.2: 1.0. Silanes used in the preparation of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylvinylchlorosilanes and tetrachlorosilanes. Most commonly used. Preferred resins are provided by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in dissolved form in low viscosity volatile or nonvolatile silicone fluids. As will be apparent to those skilled in the art, silicone resins for use herein should be fed into the composition in the dissolved form. Without being bound by theory, it is believed that silicone resins can enhance the deposition of other silicone compounds on hair and can improve the glossiness of hair with high refractive index volumes.

Other useful silicone resins are silicone resin powders, such as those provided as CTFA-named polymethylsilsequioxane, sold by Tospearl ^™ from Toshiba Silicones.

Methods for preparing the silicone compounds are described in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989.

Silicone materials and silicone resins may be conveniently recognized according to the shorthand naming system, which is particularly well known to those skilled in the art as the "MDTQ" nomenclature. In this system, silicone is described according to the presence of the various siloxane monomer units that make up the silicone. For simplicity, the symbol M represents a monofunctional unit (CH ₃ ) ₃ SiO _0.5 ; D represents a bifunctional unit (CH ₃ ) ₂ SiO; T denotes the trifunctional unit (CH ₃ ) SiO _1.5 and Q denotes the quadri- or tetra-functional unit SiO ₂ . Primes of unit symbols, for example M ', D', T 'and Q', represent substituents other than methyl and must be defined specifically for each case. Typical alternative substituents include groups such as vinyl, phenyl, amino, hydroxyl, and the like. The molar ratio of the various units as indicated in combination with the subscript or specifically the molecular weight to the subscript to the reference number indicating the total number of units of each type or average thereof in silicone completes the description of the silicone material under the MDTQ system. The high relative molar amounts of T, Q, T 'and / or Q' to D, D ', M and / or M' in silicone resins indicate high levels of crosslinking. However, as mentioned above, the total level of crosslinking may be expressed by the oxygen to silicon ratio.

Preferred silicone resins for use herein are MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred silicone substituent is methyl. Especially preferred are MQ resins having an M: Q ratio of about 0.5: 1.0 to about 1.5: 1.0, and the average molecular weight of the resin is about 1000 to about 10,000.
