Problems solved by technology

[0006] However, these types of products are still unsatisfactory
[0007] Consumers experience an annoying greasy feel after application and, moreover, sometimes find products in the form of solid emulsions to be difficult to pick with fingers
Also, since solid emulsion type products have a thick texture, it is not easy to spread evenly on the skin

Embodiment approach

[0126] According to an embodiment, the ester nonionic surfactant comprises:

[0127] i) at least one monounsaturated ester of formula (A),

[0128] R1-C(O)-O-R2 (A)

[0129] in:

[0130] R1 and R2 respectively denote C 18 ~C 44 Fatty chains, at least one of R1 or R2 are monounsaturated;

[0131] ii) at least one polyglycerol diglyceride of formula (B),

[0132] R3-C(O)-(O-CH2-CH(OH)-CH2)n-O-C(O)-R4(B)

[0133] in:

[0134] R3 and R4 respectively represent saturated straight chain or branched C 18 ~C 44 fatty chains, and

[0135] iii) at least one C 10 ~C 30 fatty alcohol.

[0136] According to an embodiment, in formula (A), R1 and R2 respectively represent C 18 ~C 40 Fatty chain, more preferably C 18 ~C 30 fatty chain. At least one of R1 or R2 is monounsaturated.

[0137] More specifically, in formula (A), the R1-C(O) group corresponds to the carbon chain of the fatty acid. The chain can be straight or monounsaturated and have at least 18 carbon atoms. Unsa...

Embodiment 1

[0180] Embodiment 1: according to the preparation of solid composition of the present invention

[0181] The solid compositions according to the invention were prepared according to the amounts given in the table below. The indicated amounts are expressed in % based on the total weight of the composition.

[0182]

Embodiment 2

[0183] Example 2: Evaluation

[0184] The applicability and cosmetic properties of the solid composition (solid paste) according to the present invention in Example 1 were measured.

[0185] According to the method described above, in 0.1 ~ 40s -1 The yield stress of the solid paste was measured using a Physica MCR 301 machine produced by Anton Paar at a shear rate of .

[0186] Also, according to the method described above, the hardness of the solid paste was measured using a TextureAnalyser machine sold by Lotun science Co., Ltd.

[0187] Subsequently, the solid composition of the present invention in Example 1 was provided to 5 consumers, applied on the skin, and the consumers gave the ratings of being easy to pick, easy to spread, and refreshing and moisturizing:

[0188] 1: Very poor;

[0189] 2: The effect is weak and unacceptable;

[0190] 3: acceptable;

[0191] 4: good effect;

[0192] 5: The effect is very good, easy to pick and spread, and there is a fresh f...

Abstract

This invention relates to a solid composition in form of oil-in-water emulsion, comprising: (i) at least one structuring agent with a melting point of greater than or equal to 50o C, (ii) at least onestructuring agent different from (i), having a melting point of less than or equal to 45 DEG C, (iii) at least one surfactant of alkyl polyglycoside type; and (iv) at least one non-ionic surfactant of ester type, comprising a mixture of at least one monounsaturated ester and at least one polyglyceryl diester.

Description

technical field [0001] The present invention relates to solid cosmetic compositions for personal skin care. Background technique [0002] The development of formulations dedicated to care and / or makeup for the skin and / or lips is endless. The formulations must exhibit satisfactory properties in terms of spreading (eg ease of application) and sensory aspects (eg hydration and / or moisturization after application). [0003] The skin is the body's protective barrier. It protects the inside of the body from physical damage (such as trauma) and biological damage (such as bacteria, viruses or fungi). Human skin includes dermis and epidermis. The epidermis is the uppermost layer of the skin, and the superficial layer of the epidermis is called the stratum corneum. [0004] Hydration is provided to the skin by water in the deep layers as well as by sweat. Dyshydration of the skin, and in particular dryness of the skin, is often observed with age and / or climatic changes. However...
