Description

No-wash hair cleaning and nursing composition

Technical Field

The invention relates to the technical field of hair washing and caring, in particular to a washing-free hair cleaning and caring composition.

Background

Today in busy schedules and fast lives, consumers do not spend much time on hair management, and therefore in daily hair care, consumers need a fast and simple solution. The advent of portable leave-on cleansing and care products eliminates the need for consumers to be distressed by emergency trips or water starvation situations, while leaving the conditioning ingredients of the leave-on product on the hair is more economical and can provide care for a longer period of time.

The patent CN 103565652B discloses a hair washing and protecting wet tissue, which comprises a hair washing and protecting wet tissue and a hair protecting wet tissue, wherein the hair washing and protecting wet tissue belongs to a washing-off type and cannot be used as a disposable one; and the cationic surfactants used in the disclosed patents are 1831 (octadecyl trimethyl ammonium chloride), 1631 (hexadecyl trimethyl ammonium chloride) and TE-90 (distearyl hydroxyethyl methyl ammonium sulfate); 1831 and 1631 are used in an amount of 2-3%, and the total amount of the two ingredients should not exceed 0.25% in the "safety and safety standards for cosmetics" of no-clean products.

Patent CN 105101936 a discloses a sheet-like hair cosmetic, and a hair treatment method and a scalp wiping method using the same, in which a liquid composition contains ethanol and a cationic conditioner. When the hair care product containing the ethanol is used for a long time, the hair is easy to dry and has no luster. In addition, the ethanol-containing product has obvious control requirements on storage, production and transportation, and causes economic and safety burden on enterprises. The cationic conditioning agent belongs to a high molecular polymer, and after the cationic conditioning agent is dissolved in an aqueous solution, the consistency of the liquid composition is increased, the spreadability on non-woven fabrics is easy to be uneven, and the utilization rate of effective substances is low.

The liquid composition B further comprises a proper amount of essence, preservative and water.

Specifically, the no-clean hair cleaning and nursing composition consists of a pure cotton non-woven fabric substrate A with uniform holes and a cation-free ethanol-free liquid composition B.

The liquid composition B comprises the following components in percentage by mass:

4-10% of amino silicone oil emulsion with emulsion particle size less than 50nm,

1 to 5 percent of water-soluble grease,

Further, the amount of penetration and water absorption of the liquid composition B into the substrate a affect the wiping operation and hair-repairing effect of the hair. The base material A is not fluffed or broken during personal use, and is preferably pure cotton, spun-laced, and has weight of 50-100g/m²4 meshes, the water absorption is more than 600 percent. Substrate A requires sufficient liquid to be wiped through the hair but does not allow dripping, preferably the ratio of liquid composition B to substrate A is from 2:1 to 5:1, more preferably 3: 1.

The blank, example 9, which contained no amino silicone oil emulsion, was clear.

Appearance results for examples 1-8, at 45 ℃:

appearance 1: after being placed for 1 week, the upper layer is provided with floating floc

Appearance 2: after being placed for 1 week, the upper layer is provided with floating floc

Appearance 3: the product is still transparent after being placed for 1 month, and has no yellowing phenomenon.

Appearance 5: after being placed for 1 week, the upper layer is provided with floating floc

Appearance 6: after being placed for 1 week, the upper layer is provided with floating floc

Appearance 7: the product is still transparent after being placed for 1 month, and has no yellowing phenomenon.

Appearance 8: the product is still transparent after being placed for 1 month, and has no yellowing phenomenon.

Blank control: example 9 contains no amino silicone oil emulsion and is clear.

Hair smoothness was evaluated, and the smoothness of examples 1 to 8 at the same addition amount was evaluated as follows:

smooth feeling 1: the slippery feel was evident in comparison to the blank (no silicone emulsion).

Smooth feeling 2: compared with the blank group, the hand feeling is not different.

Smooth feeling 3: the slippery feel was very pronounced compared to the blank (without the amino silicone emulsion).

Smooth feeling 4: compared with a blank group (without amino silicone oil emulsion), the smooth feeling is obvious

Smooth feeling 5: compared with the blank group, the hand feeling is not different.

Smooth feeling 6: compared with the blank group, the hand feeling is not different.

Smooth feeling 7: the hand feel was slightly slippery compared to the blank.

Smooth feeling 8: the slippery feel was evident in comparison to the blank (without the amino silicone emulsion).

Blank group: example 9 evaluation of smoothness of a non-amino silicone oil emulsion: the addition amount is low, and the smooth feeling is not obvious; the larger the addition amount is, the conditioning performance is obvious, but the liquid viscosity is very high, the uneven adsorption of a material body on a base material can occur, and the using performance is not fully exerted.

From the above results, it is understood that, although the particle size of the aminosilicone oil emulsion is less than 50nm, the aminosilicone oil emulsion C is more excellent than other silicone oil emulsions in the application to the liquid composition B, regardless of the room temperature, the high temperature or the smooth feeling of the hair.

The process of wiping the hair requires a sufficient amount of the liquid composition B to penetrate the hair, preferably to penetrate the hair sufficiently to impart manageability to the hair, while not dripping during use and not sticking to the palm of the hand.

TABLE 2 ratio of liquid composition B to substrate A

As can be seen from table 2, the ratio of liquid composition B to substrate a was 2:1-5:1 can be used comfortably, and 3:1 is more comfortable in the using process.

For example 1, example 3, example 4, example 7, example 8 in table 1 above, the following 3:1, preparing, and carrying out carding work test: taking straight hair strands (25 cm in length, 2.5cm in width and 10g in weight), damaged hair strands (25 cm in length, 2.5cm in width and 9.5g in weight) and 1.0g of 12% sodium dodecyl sulfate, respectively washing for 2 times, drying at room temperature, measuring the combing work of the hair product before treatment by using a TA.XT PLUS texture analyzer, and taking the average value of 8-10 times; the hair cleansing and conditioning composition was rubbed onto the hair bundle from top to bottom 2 times on each of the front and back sides and the wet combing work was measured. After drying at room temperature, the dry combing work was measured. The combing work (%) is calculated according to formula (I) and the smaller the percentage, the better the supple treatment of the sample to the hair tresses. The results are shown in FIGS. 1-2.

Referring to FIGS. 1 and 2, it can be seen that the combing work of the hair strands measured in examples 1, 3, 4, 7 and 8 was lower than that of the untreated hair strands, indicating that the easy combing performance was remarkably improved, and particularly, the easy combing effect was better in example 3.

For example 1, example 3, example 4, example 7, example 8 and the substrate in table 1 above, 3:1, preparing a composition, and probating 30 middle and long-hair women according to the form of a wet tissue product, wherein the effect is more obvious when the hair is higher according to a score of 7 points by taking refreshing and non-greasy hair and smooth, soft, moist and glossy hair after use as evaluation indexes. The test results are shown in Table 3.

TABLE 3 sensory evaluation

As can be seen from Table 3, examples 1, 3, 4, 7 and 8 all rated a high value for conditioning performance such as quick-drying, smooth, soft, easy to comb, reduced frizziness, shiny and fresh non-greasy hair, especially for example 3, with more pronounced effects on cleansing, combing and smoothing.

In conclusion, the no-clean hair cleaning and nursing composition is convenient to carry, cleans and nurses hair at any time, and enables the hair to keep fresh, clean, greasy, smooth and glossy states at any time.

In the above embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
