Description

Underwater oil type emulsified cosmetic

The present invention relates to an oil-in-water emulsified cosmetic.

In recent years, the purpose of women's use of skin care cosmetics has diversified, not only for moisturizing cosmetics, but also for whitening, brightening, reducing stains and wrinkles, and giving a feeling of firmness. Cosmetics are widely accepted. Among them, whitening and brightening are the effects required regardless of age, and many products containing various whitening active ingredients have been proposed. Originally, the whitening effect of the active ingredient gradually appears due to long-term continuous use of the cosmetic containing the whitening active ingredient, and it is difficult to immediately feel the whitening effect immediately after applying the cosmetic.

Therefore, in order to produce an effect of instantly brightening the skin instead of the immediate whitening effect, a white pigment or powder such as titanium oxide or zinc oxide is used to impart whiteness and brightness to the decorative film. There is a method called.

Special Table 2005-526781

The main object of the present invention is to provide an oil-in-water emulsified cosmetic that can instantly produce an effect of brightening the skin and has an excellent glossy finish.

By the way, as skin care cosmetics, what is called vanishing cream has been known for a long time, and vanishing cream is an oil-in-water emulsion that looks like "vanish" as its name suggests, and is applied to the skin. Then, it becomes white at first and gives an appropriate feeling of frictional resistance, but it permeates so as to disappear, and is characterized by a refreshing matte finish (see, for example, Patent Document 1). Most vanishing creams contain higher fatty acids and higher alcohols, but if a large amount of these solid surfactants is added, the interface of the emulsified droplets becomes harder and the stability of the emulsion improves, but it does not burnish. (It does not disappear), so that it remains white, and the glossy or penetrating feeling of the skin is lost, and a hard film feeling tends to remain.

As a result of repeated diligent research to solve the above problems, the present inventor focused on the white residue when the vanishing cream was applied, and as a result of further diligent research, the anionic surfactant had 12 to 22 carbon atoms. It was found that the above-mentioned problems can be solved by making an oil-in-water emulsified cosmetic prepared by blending at least four components of a higher alcohol, an oil having a water holding capacity of 140% or more with respect to its own weight, and a phenyl-modified silicone. , The present invention has been completed. Furthermore, the present inventor has also found that the oil-in-water emulsified cosmetic of the present invention can immediately produce an effect of brightening the skin without including a white pigment. Further, as a more preferable embodiment, the present inventor can also provide an oil-in-water emulsified cosmetic having an effect of instantly brightening the skin and having a soft cosmetic film and an excellent glossy finish.

Test method: As a method for testing the water holding capacity of the present invention as to whether or not to hold water (mass) equal to or more than its own weight at 50 ° C., 20 g of the starting oil (initial sample) is weighed in a 200 mL beaker. Heat to 50 ° C and gradually add water at 50 ° C while stirring at 3000 rpm with a desper mixer, add water until the water drains from the sample, and the maximum mass of water that does not drain. The amount of water added) was measured, this value was divided by the mass (20 g) of the oil agent (initial sample), and the value multiplied by 100 was calculated as "water holding capacity (%)".

Regarding the above test method, more specifically, when the added water is visually observed as if it is being flipped on the agitated oil agent, "water is not drained". It can be determined that the time has changed to "water is drained", and the addition of water is terminated at this change. After completion, discard the drainage (water) floating on the upper part of the oil agent (maximum water-holding sample) that has been maximally embraced. The mass of the maximum embraced oil (maximum embracing sample) in the beaker from which the drainage (water) is discarded can be measured, and this mass can be defined as the "maximum mass of water that the water does not drain". .. Note that this observation is not limited to visual observation, and may be performed using an image sensor.

(Evaluation method 1)
(B. White residue at the time of application)
Apply a cherry-sized formulation (about 2 g) to the inner part of the forearm, and apply the formulation to the part from the base of the palm to the elbow at a constant speed (1 reciprocation in 1 second), and the formulation quickly blends into the skin and disappears. Instead, the time to spread white was measured with a stopwatch.
<Criteria>
(Judgment): (Evaluation)
⊚: White remaining for 5 seconds or more: Very good ○: White remaining for 2 to 5 seconds: Good △: 1 to 2 seconds White remaining: Slightly defective ×: White remaining for 2 to 2 seconds or less: Defective

As a more specific explanation, a specialized panel for applying a cherry-sized preparation (about 2 g) on the skin on the medial side of the forearm and rubbing it is from the base of the palm to the elbow (the hollow on the inside of the arm opposite the elbow). With the palm of your hand, apply the formulation back and forth between the parts so that it rubs at a constant speed (one reciprocation per second), and let it blend in. By reciprocating and rubbing the formulation, the formulation does not fit the skin at first and spreads white, so that the skin looks white, and by further rubbing, the white residue (white) of the formulation disappears. The specialized panel that determines the white residue determines that the product is "familiar" when it disappears. The specialized panel that determines the white residue measures the period (time) from the start of application of the specialized panel to be rubbed to the time when the formulation is familiar to the skin by rubbing, and this time is measured at the time of application. The white remaining time at the time of application is evaluated according to the above <judgment criteria>.

(Evaluation method 2)
Women in their 20s to 40s were trained in sensory evaluation, and 10 specialized panels that could be evaluated according to certain criteria were selected. Each sample was used for the forearm of the specialized panel, and the softness of the cosmetic film felt at the time of use and the glossiness of the skin after application were evaluated on a 5-point scale by the following absolute evaluation and graded. Further, regarding the softness and glossiness of the cosmetic film, the average value was calculated from the total score of all the panels for each sample, and was judged according to the following four-step judgment criteria.

(B: Softness of makeup film)
<Absolute evaluation criteria>
(Score): (Evaluation)
5 points: I feel that there is no film hardness after application 4 points: I feel that there is no film hardness after application 3 points: Normal (neither good nor bad)
2 points: Slightly feels that there is film hardness after application 1 point: Feels that there is film hardness after application <4 grade criteria> (The same applies to the following evaluation items)
(Judgment): (Average score)
◎: More than 4.5 points: Very good ○: More than 3.5 points and less than 4.5 points: Good △: More than 1.5 points and less than 3.5 points: Slightly poor ×: More than 1.5 points : Bad

It should be noted that the absence of film hardness after application means that the cosmetic film is soft and has no hardness, and the slight feeling that there is no film hardness means that the cosmetic film feels slightly soft. .. Feeling that there is film hardness means that the cosmetic film feels a little hard, and feeling that there is film hardness means that the cosmetic film feels that it is hard. The soft film feeling means the softness of the cosmetic film that is felt.

(C: glossy feeling)
<Absolute evaluation criteria>
(Score): (Evaluation)
5 points: Feels that the skin is glossy 4 points: Feels that the skin is slightly glossy 3 points: Normal (neither good nor bad)
2 points: I don't feel that my skin is glossy 1 point: I don't feel that my skin is glossy
