Description

  The present invention relates to a moisturizing cosmetic. More specifically, the present invention relates to a moisturizing cosmetic suitably used for skin or hair.

  Cosmetics that moisturize the skin or hair include water-based cosmetics such as lotion, mist lotion, and gel. These water-based cosmetics can impart a more preferable moisturizing effect to the skin or hair by blending a high amount of moisture and further blending moisturizing ingredients such as polyhydric alcohols and amino acids.

  However, the above attempt has a drawback that the moisturizing effect is not durable. Therefore, attempts have been made to highly blend moisturizing ingredients such as polyhydric alcohols and amino acids in order to increase sustainability, but not only the stickiness is increased and the usability is inferior, but also effective sustainability is sufficient. There is a problem that it is difficult to obtain. Therefore, an attempt has been made to increase the sustainability of the moisturizing effect by blending oil to form a film on the skin, preventing evaporation of moisture. Specifically, skin cosmetics containing betaines and silicones (see, for example, Patent Document 1) have been proposed.

  However, when the amount of oil sufficient to satisfy the moisturizing effect and sustainability is blended, the sustainability is improved, but the stickiness after application, oiliness, and the film thickness are inferior. There is. There is also a problem that washing off from the skin and hair becomes worse.

  In order to solve such problems, attempts have been made to impart a moisturizing effect without blending oil. For example, liquid skin cosmetics containing animal and plant extract moisturizing ingredients, low molecular weight hyaluronic acid and citric acid (see, for example, Patent Document 2), specific plant extracts, amino acids, peptides, proteins, polyhydric alcohols, higher grades Skin external preparation containing a component selected from alcohol, phospholipid, glycolipid and steroids (see, for example, Patent Documents 3 and 4), Coenzyme Q10, and a moisturizing cosmetic containing a moisturizing component (for example, Patent Document 5) See), water-soluble polyhydric alcohols, mucopolysaccharides such as hyaluronic acid, and external preparations for skin containing polyoxyalkylene alkyl glucoside (see, for example, Patent Document 6).

  However, although a certain amount of moisturizing effect can be imparted based on these attempts, the durability of the obtained moisturizing effect is not yet satisfactory. In addition, when a high moisturizing component is added to give a sufficient moisturizing effect, there is still a problem that the sticky feeling is increased and the feeling of use is inferior.

  Therefore, recently, as a component that has both hydrophilic and lipophilic functions and imparts a moisturizing effect, cyclohexanedicarboxylic acid diesters such as cyclohexanedicarboxylic acid bisethoxyglycol (see, for example, Patent Documents 7 and 8), glycerin An alkylene oxide derivative (see, for example, Patent Document 9) has been developed, and attempts have been made to blend it into cosmetics using water as a medium.

  However, even though these attempts can provide a certain amount of moisturizing effect, the sustainability of the resulting moisturizing effect is still not fully satisfactory. In addition, if a high moisturizing ingredient is added to give sufficient sustainability, the skin feels bad when applied and the skin feels squeezed or the skin becomes sticky after application. There is still the problem of being inferior.

(Test Example 1: Evaluation of durability of moisturizing effect (measurement of keratin water content))
The durability of the moisturizing effect of each sample obtained in the examples and comparative examples was individually evaluated by 10 subjects. That is, the inner side of the forearm of each subject was washed with solid soap, then lightly wiped with a towel, and acclimated for 10 minutes in a constant temperature and humidity chamber at a temperature of 21 ± 2 ° C. and a humidity of 50 ± 5%. Thereafter, the initial value of the stratum corneum water content at the measurement site was measured with a skin surface stratum corneum water content measuring device (Coroneometer CM820; manufactured by Curage + Khazaka electronic).

  Next, 2 mL of each sample was impregnated into 2 × 2 cm cotton, and the sample was attached to the same measurement site as above for 10 minutes, and then the cotton was removed. Immediately after the removal, the keratin water content was measured in the same manner as before, after 10 minutes, 20 minutes, 30 minutes, 90 minutes, and 120 minutes. Thereafter, the measurement site was washed away with running water, allowed to dry naturally, and the amount of keratin moisture after 20 minutes was measured. The results are shown in Table 2.
