COSMETIC COMPOSITION COMPRISING A CATIONIC SURFACTANT, A FATTY ALCOHOL, AN AMPHOTERIC SURFACTANT, A STARCH DERIVATIVE, AND A

CATIONIC CONDITIONING POLYMER FIELD OF THE INVENTION

The present invention relates to a composition for cleansing hair fibers comprising (a) one or more cationic surfactants; (b) one or more amphoteric surfactants; (c) one or more fatty alcohols; (d) one or more starch derivatives; (e) one or more cationic conditioning polymers; (f) one or more amino silicones; and (g) water. These compositions impart detangling properties, curl definition, volume control, discipline, softness, conditioning, and hydrating properties to hair fibers.

The invention also concerns a process for cleansing and conditioning hair fibers and a use for hair care employing the composition.

BACKGROUND OF THE INVENTION

Hair is generally damaged and embrittled by the action of external atmospheric agents such as sunlight, and also by mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and/or relaxing.

Hair is thus damaged by these various factors and may over time become dry, coarse or dull, especially in fragile areas, and more particularly at the ends leading to split ends.

Cleansing compositions typically contain anionic surfactants. Anionic surfactants such as sodium lauryl sulfate have detergent properties and are highly effective at removing dirt and oil. However, anionic surfactants raise the cuticle of the hair for deep cleansing, but raised, rough cuticles also lead to frizz. Consumers with damaged, delicate, dyed, or curly hair find products containing anionic surfactants to be too drying and damaging for frequent use, and, as a result, choose mild cleansing compositions which have low levels of anionic surfactants.

However, there are drawbacks associated with mild cleansing compositions. On account of their low detergency, excess oils and styling products may not be effectively removed from the hair. This may make the hair flat and feel greasy, and with repeated use, the hair does not feel clean.

Consumers are therefore still in search of optimized cleansing compositions, for obtaining adequate visual sleekness of the hair; good feel of the hair, and in particular of wet hair; control, or even elimination, of frizziness, and also control or reduction of the volume and of the apparent mass of the head of hair, the said compositions thus being most particularly suitable for curly, damaged, and/or voluminous hair. Consumers having dyed hair are also in search of cleansing compositions which prevent color fading.

Applicants have surprisingly found that their compositions comprising

(a) one or more cationic surfactants; (b) one or more amphoteric surfactants; (c) one or more fatty alcohols; (d) one or more starch derivatives; (e) one or more cationic conditioning polymers; (f) one or more amino silicones; and (g) water effectively clean the hair and provide conditioning and hydrating properties, detangling, and curl definition without leaving the hair frizzy, flat, or feeling greasy.

SUMMARY OF THE INVENTION

The present invention is directed to compositions comprising:

(a) one or more cationic surfactants;

(b) one or more amphoteric surfactants;

(c) one or more fatty alcohols;

(d) one or more starch derivatives;

(e) one or more cationic conditioning polymers;

(f) one or more amino silicones; and

(g) water

The compositions in accordance with the invention may be used for cleansing hair fibers, for example as hair cleansers or shampoos.

The present invention is also directed to methods of applying to the hair a composition as defined above. The compositions according to the invention may be used alone or in conjunction with a hair conditioning and treatment regimen.

The ingredients of phase B were added to the main kettle with a portion of water and mixed at 80°C. The contents of the side kettle were added to the main kettle followed by mixing. The ingredients of phase C were added to the main kettle with mixing. The temperature of the main kettle was cooled to 70°C, and the ingredients of phase D were added followed by mixing. An additional portion of water was added to the main kettle, and the temperature was lowered to 45°C with mixing. The ingredients of phase E were added to the main kettle followed by mixing.

A quantitative (monadic) test was conducted to obtain consumers' opinion, perceptions and overall satisfaction with Example 2 compared to Example 3. The test panel contained 800 women having hair types I to V who are regular users of a shampoo and conditioner regimen. Hair types were further separated by transformed and not transformed hair. Panelists participated in a blinded home evaluation for 15 days. Panelists were instructed to use the test product as they normally would in place of their usual shampoo and conditioner regimen for 7 days. After 7 days of use, panelists responded to a semi-qualitative questionnaire with closed questions. The results are summarized in Table 3.

For overall liking ratings and most benefits of the inventive composition, Example 2, were found to be on par with the comparative example, Example 3. In addition, overall, Example 2 performed better than Example 3 in the areas of frizz control, hydration on dry hair, ease of combing wet hair, reduced hair breakage. Also, Example 2 performed better than Example 3 in the areas of softness, moisturizing, prevents color fading and lightness for types I to V dyed hair. For other attributes such as keeps hair clean throughout the day, reduced hair breakage/ loss, left hair moisturized, protection from the heat of flat iron or blow-dry, does not make your hair look dirty quickly, and texture/ consistency (tending to thick), the panel preferred Example 3 over Example 2 only when tested on hair type III (not transformed).
