Description

Fluffy shampoo composition

Technical Field

The invention belongs to the field of daily chemicals and relates to a fluffy shampoo composition.

Background

In recent years, a small amount of hair becomes a heart disease of more and more people, and the hair loss phenomenon shows a tendency to be younger. The effectiveness of a plurality of anti-hair loss and hair growth products on the market is doubtful; the investment of the hair implantation operation is high and has a certain risk. However, if the hair is sufficiently fluffy, the amount of hair can be visually significantly increased. Fluffy is that the hair looks like a very layered feeling with gaps instead of close fitting and collapse. According to 2021 scalp health white paper, the oil control and fluffiness effects become popular trends, and the proportion of people consuming the oil control and fluffiness washing and protecting products after 95 years is improved year by year; and the consumption level of the 95-th crowd is almost equal to that of the 80-th crowd. The oil-control fluffy product has huge market and wide prospect.

Healthy hair is very tough, but keratin in hair is easily damaged by excessive physicochemical treatments such as combing, blowing heat, dyeing, perming, etc., and the hair is roughened, losing luster, thereby reducing softness and flexibility, and the hair is difficult to finish due to increased friction, broken hair or forked ends occur, and the hair becomes thin, loses elasticity, and loses vitality and sags, thereby losing fluffiness. Shampoo is used for cleaning the grease, sweat scale, cell falling off scalp, foreign dust, microorganism, residue of shaping product and bad smell, etc. adhered on scalp and hair, keeping scalp and hair clean and hair beautiful. However, shampoos with various additional functions are also becoming popular due to the diversity of people's needs.

Currently, cationic conditioning agents are used in most shampoos to promote hair volume, generally by repelling the hair with a repulsive cationic charge. The cationic conditioning agent is adsorbed on the surface of hair through the action of charges, has stronger accumulation property than silicone oil, and is easy to adsorb more dust particles when the hair is contacted with the outside air, so that the scalp is continuously stimulated to secrete grease, and the grease is mixed with the dust to form grease so as to aggravate greasy hair. The more the use frequency is increased, the more cations are accumulated, the pores are tightly wrapped by the accumulated matters, the hair follicle respiration is blocked, the oxygen permeation is insufficient, the hair papilla is gradually atrophic, and then the alopecia occurs. The hair care effects such as softness and the like can be achieved in a short period, but the cleaning force, the poor oil control and fluffy effects of the shampoo can be reduced after long-term use, and the oil output of the scalp is increased.

Chinese patent application CN 109419643A discloses a shampoo composition comprising an aqueous polyurethane, a detersive surfactant, a conditioning agent and a carrier; the shampoo composition has the characteristics of good film forming elasticity, high glossiness, good toughness and non-sticky hand feeling through the unique design of polyurethane molecules in the aqueous polyurethane dispersion, and brings brand new natural plumping effect to hair after washing. However, the composition improves the hair bulk through the film formation of the aqueous polyurethane, is easy to deposit on the hair in the continuous multiple use process, so that the hair is heavier and the bulking effect is affected. And has no effect on hair flattening and collapse caused by hair peel oil production, and has no lasting fluffing effect.

Chinese patent application CN 109620754A discloses a low-irritation hair-volume shampoo composition comprising the following components in mass percent: 0.5-1.5% of nonionic surfactant, 9-25% of anionic surfactant, 0.5-5% of zwitterionic surfactant, 0.05-5% of cationic conditioning agent, 0.05-11.5% of grease, 0.01-10% of suspending agent, 0.01-5% of higher fatty alcohol and the balance of pure water. The invention adopts mild surfactant and reasonable conditioner collocation, and has the effects of small irritation and capability of remarkably increasing the hair after washing. However, the shampoo composition mainly reduces electrostatic adsorption of hair through flocculating deposition of cationic guar gum, polyquaternium-10, silicone oil conditioning agent and the like, so that the effects of plumping and fluffing hair are achieved. Has no effect on hair flattening and collapse caused by scalp oil extraction, and has no lasting fluffing effect.

Therefore, it is necessary to explore a shampoo composition which is strong in cleaning power and oil control and good in bulking effect.

2. Testing

1. Hair volume change before and after shampoo application

The volume of hair is related to the total combined volume of hair fibers on the head rather than the volume of individual fibers. Depending on the style and length of the hair, individual fibers of the hair contact and help support other fibers, thereby maintaining the structure of the hair as a whole. All hair fibers of the hair strand are fixed at one end, not thousands of points on the scalp, respectively, and the hair fibers in the hair strand cannot be regarded as a space-filling structure as the actual hair, but rather the hairs should be mutually supported to generate a volume. The human model volume measurement method is used, which is closer to the human hair and the test is more reliable.

The manikin head used in the volume experiments was purchased from amazon, RYHAIR Store, USA, and was rinsed with a detergent solution containing 20% sodium laureth sulfate and 5% cocamidopropyl betaine prior to the experimental treatment. To reduce entanglement, the hair is rinsed with running water at 38 ℃ with a ventilation brush (vent brush) to clean and clear the hair. The model head was washed twice with 5mL of detergent solution each time, followed by 2.5mL of solution, after which the hair was combed through with a brush. The hair is then allowed to dry overnight and must be combed as flat as possible to give a measured intrinsic volume V _(front) The influence of the hair style is minimal.

In the volume experiment, first moistened with 38 ℃ water, then 3mL of shampoo was rubbed into the hair for 30 seconds, then rinsed with 38 ℃ water for more than 60 seconds until the rinse water was clear and transparent. Volume measurements were made after one application and were run in duplicate. The apparent change on the mannequin head was measured using a Zeiss Kontron image analyzer with a Sony XC-77CE miniature camera (with a 60mm Nikon AF Micro-Nikkor lens) attached. The human body model image is taken by camera and is processed by computer to obtain the hair volume V of human body model head _(rear) 。

Volume change rate V% = 100% × [ V _(rear) －V _(front) ]/V _(front)

A statistical p-value was used to verify whether the data was reliable, a p-value greater than 0.05 indicated that the data was not statistically significant at the 95% confidence level. Note that the data is the average of at least 5 evaluations.

TABLE 3 Hair volume change after different shampoos

The volume increase reported in table 3 is all statistically significant p <0.05, the magnitude of the volume increase being 7.7-39.5%, indicating that the compositions of the present invention are very effective in significantly increasing hair volume, comparing examples 1-3 to comparative example 1, a significant increase in hair volume was observed with the treatment with the compositions containing fluffy composition (referred to herein as polyurethane, silica disilylate, wild soybean seed extract three components), confirming that the fluffy effect is from a fluffy composition; comparing examples 1-3 with comparative examples 2-8, the result is a fluffy composition in which the polyurethane, silica disilylate, and wild soybean seed extract are used in combination in a certain ratio, and the hair volume increasing effect is most pronounced, and the effect is deteriorated when either or both of them are absent; comparative example 9 the comparative example 9 was slightly less effective than example 1 in that polyglycerol-10 oleate was used instead of the wild soybean seed extract on the basis of example 1, and the volume change rate of the hair of example 1 was almost twice that of comparative example 9; comparing examples 1-3 with comparative examples 10-12, the hair volume increasing effect of the resulting leave-on shampoo compositions of the invention is superior to the commercial products.

2. Oil control human body test evaluation

Equipment and equipment are used: grease strip (CK, germany), meibomeMB560 scalp grease tester (CK, germany), skin pen, rubber band, stopwatch timer, blower.

According to the principle of a grease testing photometer, the adhesive tape strip used in the skin grease testing method, namely the Sebumeter method, is bent into a circular ring to be contacted with the scalp, the transparency of the testing adhesive tape is changed by lipid compounds (grease) in the scalp, and then the testing adhesive tape strip is flattened and then is put into a sliding block of an instrument, and the sliding block is pushed into the instrument. The light transmittance distribution curve on the adhesive tape can be obtained through testing by a photoelectric tube in the instrument, the peak value of the light transmittance distribution curve represents the content of lipid compounds, namely grease, in the scalp, and the annular top end of the adhesive tape is just the part which is in full contact with the scalp during testing.

90 volunteers with vigorous scalp grease secretion are recruited, the age is 20-30 years, the hair is not washed at night before the test, the grease secreted by scalp sebaceous glands is more easily adhered to hair roots in a spreading manner under the condition of comb hair combing, and the volunteers are required to not comb hair as much as possible in a test area. Examples 1-3 and comparative examples 1-12, 15 shampoos total, each of which was randomly drawn out for trial by 6 volunteers.

The volunteers were allowed to sit still in a room at a temperature of 20-22 c and a humidity of 40-65% for 30min before testing, during which time they were unable to drink water and beverages. The test part is exposed, placed in a test state and kept relaxed. The test time points are immediately before, immediately after, 6 hours after and 8 hours after the sample. The test site was taken as a forehead-top 5cm area and a 1cm x 1cm square was drawn on the test area with a skin pen. And (3) during sample application, testing the grease content at the test part for three times respectively for analysis. The same method is adopted by the same person to wash the hair of the volunteer when the hair is washed, and the hair of the volunteer is dried by using medium-grade hot air of a blower.

Because scalp oil secretion is a dynamic continuous process, scalp oil content varies at different times after shampooing. Whereas the evaluation of the oil control efficacy of the washing and care product is actually to determine the temporary sebum level of the scalp, i.e. the amount of oil spilled out of the hair follicle after sebum secretion. If the skin surface is degreased, sebum will be excreted at a rapid rate, taking about 4 hours to recover to a temporary level, entering the sebum secretion phase. If after 3-4 hours after shampooing the sample, only sebum excretion is measured, not sebum secretion. Thus, the oil content measurement time point of the scalp oil control test should be greater than 4 hours.

SPSS19.0 statistical software is adopted for data analysis, T-test or rank sum test is adopted for comparing data distinction before, immediately after, 6 hours after and 8 hours after the sample, and significance analysis is carried out.

TABLE 4 sample forehead skin oil content

Formulation of	Scalp fat content before application (μg/cm) ² ) (mean.+ -. Standard deviation)
		Example 1	450.7±125.1
Example 2	473.4±108.1
		Example 3	455.6±123.6
Comparative example 1	453.3±127.6
		Comparative example 2	490.3±129.6
Comparative example 3	469.3±138.9
		Comparative example 4	468.3±113.7
Comparative example 5	444.9±126.9
		Comparative example 6	479.6±119.6
Comparative example 7	465.3±126.4
		Comparative example 8	461.7±130.4
Comparative example 9	477.9±109.6
		Comparative example 10	459.6±117.5
Comparative example 11	478.3±123.6

The data in table 4 show that there was no significant difference in scalp fat content of the test group as the basis value of the study prior to sampling, which also ensured the scientificity and rigor of the subsequent test.

TABLE 5 forehead skin oil content at various time periods after the sample

The scalp fat content was measured for 90 volunteers over a test period, and the experimental results are shown in table 5. Comparing the scalp fat content data of examples 1-3 and comparative examples 1-12 at 6 and 8 hours after sampling, three components of polyurethane, disilylated silica and wild soybean seed extract in the fluffy composition can be obtained, when the composition is used together, the scalp fat content is lower, any one or two components are absent, or one component is replaced, the scalp fat content is increased, and the effect is better when the composition is arranged in a certain proportion range; at the same time, the scalp fat content of the present invention's leave-on shampoo compositions (i.e., examples 1-3) was lower than that of the commercial products.

3. Human sensory evaluation

150 volunteers with few and thin and soft hair are selected, and the volunteers have the phenomena of flat hair, lack of fluffiness and the like with different degrees at ordinary times, and simultaneously have the symptoms of head oil and dandruff, and the scalp of the patient is subjected to sensory and hair image evaluation before the product is tried out, so that the volunteers are ensured to meet the requirements of the test.

Examples 1-3 and comparative examples 1-12, 15 shampoos total, each of which was randomly drawn from 10 volunteers for trial use.

Volunteers used samples once a day for two weeks. During the trial, the degree of hair collapse and the hair volume were recorded separately, and after two weeks, comprehensive scoring was performed, see table below.

The volunteers scored before and after use, with higher scores being better.

1-2: the hair conditioner is ineffective, the hair fluffiness condition is evaluated after each hair washing, and the hair collapse state and the hair crumbs fluffiness condition are the same as those before use;

2-3: effectively, the hair bulk is evaluated after each hair washing, and the flat state of the hair and the fluffy condition of the dandruff are improved;

3-5: the hair conditioner is powerful, and after each shampooing, the hair bulk is evaluated, the flat state of the hair and the fluffy condition of the dandruff are improved, the hair becomes relatively dense and fluffy, the hair can last for 24 hours, the hair oil is obviously reduced, and the dandruff is also reduced.

The volunteers were subjected to sensory evaluation after using the inventive examples, comparative example products, and the results are shown in table 6.

TABLE 6

As can be seen from the data in Table 6, the number of volunteers experiencing the high sensory effect was higher and the number of sensory nulls was lower in examples 1-3, and comparative examples 2-8, which lacked either or both components, had the polyglycerin-10 oleate instead of the wild soybean seed extract, had the lower number of volunteers experiencing the high sensory effect, and had the higher sensory nulls, and had the better effect at the given ratio.

Finally, it should be noted that the above description is only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and that the simple modification and equivalent substitution of the technical solution of the present invention can be made by those skilled in the art without departing from the spirit and scope of the technical solution of the present invention.
