Description

Technical Field

[0001] The invention belongs to the field of daily chemicals, and particularly relates to a hair care composition containing carrot seed oil. Background Art

[0002] In recent years, the consumption proportion of hair care products in the category of shampoo and conditioner has gradually increased, and consumers are paying more attention to the health of their hair and scalp. Modern consumers generally face problems such as dandruff, excessive oil secretion, hair loss, dry hair, frizz, and yellowing hair. In addition, with the rise of a new generation of young consumers who pay attention to their own image, healthy, shiny, non-greasy, tangle-free, easy to comb, and silky hair has become their ideal hair type. However, under the attack of ultraviolet rays, air pollutants, etc., hair is easily oxidized, resulting in the loss of protein in the hair, making the hair rough, dry, dull, and even withered and brittle. These problems affect the hair quality of consumers, making the demand for hair care products more urgent. Overall, the repair and health care of hair has become an important direction for the research and development of hair care products.

[0003] At present, the common types of hair care products on the market include shampoo, conditioner, hair mask, hair oil, hair spray, wash-free conditioner and scalp care products. Among them, shampoo mainly provides cleaning and softening functions, but when the conditioning effect is too heavy, it is easy to cause excessive deposition of cationic components including guar gum and silicone oil, which makes the hair greasy, flat and lack luster. Conditioners and hair masks are mainly formed by gelation of cations and fatty alcohols, combined with silicone oil to achieve the purpose of untangling, softening and repairing hair. However, these products need to be rinsed with a lot of water after use, which is not conducive to environmental protection. Due to formula restrictions, the content of effective ingredients left on the hair is often limited, especially for severely damaged or split hair. The effect is not good. Although hair oil can make hair look smoother and shinier, its silicone oil content is generally high, which is easy to leave residue on the hands, making users feel greasy, thus requiring additional washing, reducing the convenience of use.

[0004] Therefore, it is necessary to innovate hair care compositions to meet the needs of the market and consumers, and develop a hair care composition containing plant-derived active ingredients that can not only soften hair, solve problems such as dull and dry hair, hard and brittle hair, split ends and breakage, and frizzy hair, but also give hair better conditioning, improve hair quality, and enhance hair gloss.

[0071] The results of the above laboratory instrument efficacy evaluation and consumer sensory evaluation are shown in Table 2.

[0072] Table 2:

[0073]

[0074]

[0075] As can be seen from Table 2, compared with Comparative Examples 1-3 without adding carrot seed oil and / or hydroxypropyl tetrahydropyrantriol, Examples 1-3 of the present invention have a synergistic effect by applying the combination of carrot seed oil and hydroxypropyl tetrahydropyrantriol to a hair care composition containing a higher fatty alcohol, a hair conditioner, and a hair moisturizer, thereby obtaining a more excellent moisturizing and nourishing effect, improving dry and wet combing properties, enhancing glossiness, and enhancing antistatic force and tensile strength. The applicant unexpectedly discovered that the technical effect of applying the combination of carrot seed oil and hydroxypropyl tetrahydropyrantriol to a hair care composition is superior to the sum of the effects of applying carrot seed oil and hydroxypropyl tetrahydropyrantriol alone to a head care composition. The hair care composition provided in the embodiment improves the dry and wet combing effect of hair, reduces the knotting and entanglement of hair, and reduces the pulling and damage to hair; improves the glossiness of hair, makes hair glow with natural luster, and makes hair look healthier and brighter; significantly enhances the antistatic ability of hair, reduces static electricity accumulation, keeps hair smooth and not easy to tangle; enhances the tensile strength of hair, gives hair stronger toughness and elasticity, and reduces breakage and split ends. In addition, the embodiment hair care composition also greatly reduces the irritation of use and low irritation to the skin, giving consumers a good use experience. The best preferred ratio of the hair care composition of the present invention is 2-5% carrot seed oil, 1-2.5% hydroxypropyl tetrahydropyrantriol, 1-8% higher fatty alcohol, 1-2.5% hair conditioner, 2-6% hair moisturizer, and the balance of water.

[0076] Compared with Example 3, Comparative Example 4 increases the formula ratio of hydroxypropyl tetrahydropyrantriol, which improves the dry and wet hair combing properties, hair gloss and moisturizing effect to a certain extent. However, compared with Example 3, the hair care composition of Comparative Example 4 has obvious differences in improving the dry and wet hair combing properties, antistatic force, tensile strength, hair gloss and scalp moisture content of hair. At the same time, the composition of Comparative Example 4 will slightly increase the irritation of the use feeling.

[0077] Compared with Example 1, Comparative Example 5 selects oat kernel oil and hydroxypropyl tetrahydropyrantriol to be applied to a hair care composition containing a higher fatty alcohol, a hair conditioner, and a hair moisturizer, which has a certain improvement on the glossiness and smoothness of the hair bundle, but the effect is not obvious.

[0078] In summary, the present invention selects to apply carrot seed oil and hydroxypropyl tetrahydropyrantriol in combination to a hair care composition containing a higher fatty alcohol, a hair conditioner, and a hair moisturizer, which has a synergistic effect of moisturizing and nourishing the hair, improving dry and wet combing properties, enhancing glossiness, and enhancing antistatic force and tensile strength. The hair care composition can create a good microecological environment for the scalp with a balance of water and oil; improves the dry and wet combing effect of the hair, smoothes and softens the hair, reduces the degree of hair entanglement, and reduces hair pulling and damage; improves the glossiness of the hair, resists oxidation, makes the hair glow with natural luster, and makes the hair look healthier and brighter; significantly enhances the antistatic ability of the hair, reduces static electricity accumulation, keeps the hair smooth and not easy to tangle; enhances the tensile strength of the hair, gives the hair stronger toughness and elasticity, and reduces hair breakage and split ends; the hair care composition can effectively repair damaged hair and solve the problems of yellowing, drying, and easy breakage of hair caused by damage and oxidation.

[0079] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0080] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
