Embodiment 1

[0212] Example 1: Formulation Example

[0213] Prepare the following recipe:

[0214]

[0215] Note: Comparative Formulation 1 does not contain superabsorbent polymer; Comparative Formulation 2 does not contain modified starch.

[0216] Preparation method (the formulation was prepared using a homogenizer V2004 of the TURBOTEST brand from the company VMI RAYNERI):

[0217] Heat water phase A1 to 70°C, mix fat phase B and heat to 70°C, add phase B to phase A1 at 70°C, use homogenizer for 15 minutes; add phase A2 to mixture at 70°C , using a homogenizer for 15 minutes. Then, the mixture was cooled to 25°C and phase A3 was added to it.

[0218] program:

[0219] Inventive formulations 1 and 2 and comparative formulations 1 and 2 were prepared with the aid of a Howden B.V. Mondomix pressurized continuous beater. After starting and adjusting the parameters, start whipping the recipe.

[0220] for the T 0 For the four formulations prepared below, a cream with a "chantilly" ...

Embodiment 2

[0221] Example 2: Evaluation Example

[0222] The inventive and comparative formulations prepared in Example 1 were evaluated for density, stability and sensory effects.

[0223] The density of the formulation was tested using a Gardener pycnometer at 20°C.

[0224] Stability testing of the inventive and comparative formulations at 25°C, 40°C and 45°C for two months was performed using a Binder oven (USA) by leaving the inventive and comparative formulations in the oven for 2 months .

[0225] The stability test at 4°C for two months was performed using a Zhongke Meiling refrigerator (YC-260L, China) by leaving the inventive and comparative formulations in the refrigerator for 2 months.

[0226] Shipping and pressure stability testing was performed by air shipping the formulation of Example 1 from China to India (6 hours).

[0227] Finally, a sensory effect test of the inventive and comparative formulations was carried out in India by applying the formulation obtained in Exam...

Abstract

The present invention relates to an oil-in-water composition in the form of A oil-in-water composition in the form of a foam having a dispersed fatty phase in a continuous aqueous phase, having a density of 0.3 to 0.95, wherein the composition comprises: a) at least one starch phosphate; 5 b) at least one superabsorbent polymer; c) at least one hydrophilic gelling polymer chosen from hydrophilic anionic associative polymers, hydrophilic anionic non associative polymers, or a mixture thereof; and d) at least one surfactant.

Description

technical field [0001] The present invention relates to the field of cosmetics in foam form, in particular low density compositions with a whipping texture. Background technique [0002] In the field of cosmetics, more particularly in the field of skin care, photoprotection or make-up, it is a practice known from patent application US2010 / 033 018 to introduce highly water-absorbing polymers into oil-in-water or water-in-oil emulsion types in galenical forms because they impart texture-favorable sensory effects, such as moisturization, freshness or reduced stickiness. [0003] WO2013 / 087926 discloses compositions for topical application comprising at least one aqueous phase, at least one fatty phase, at least one superabsorbent polymer and having a specific surface area per unit mass (S M ) of hydrophobic silica airgel particles. The product itself can be applied evenly to the skin without pilling after application. [0004] Other key attributes of cosmetic products of gre...
