- Polyacid anhydrides having crosslinked the carboxyalkylated starch can be mixed polyacid anhydrides such as mixed adipic-acetic anhydride.
- Polyfunctional basic organic molecules having crosslinked carboxyalkylated starch can be polyphosphates.
- Their metal salts can be sodium, manganese, calcium, manganese, iron, copper or zinc salts.
- a preferred variant of crosslinking agent is the sodium salts of polyacids, such as sodium trimetaphosphate, sodium tripolyphosphate.
- crosslinking agents which have crosslinked the carboxyalkylated starch can be the aldehydes polyfunctional, such as glyoxal; halogenated epoxides, such as epichlorohydrin; aliphatic or aromatic diisocyanates, the alkyl chain of which has less than 8 carbon atoms, such as hexamethylene diisocyanate; oxohalides, such as phosphorus oxychloride.
- the carboxyalkylated and / or crosslinked granular starch is present in the emulsion at a percentage ranging from 1% to 20%, preferably from 3% to 18%, most preferably from 5% to 15%, by weight relative to the total weight of said emulsion.
- the emulsion according to the invention can be an oil-in-water emulsion obtained by emulsifying a fatty phase in an aqueous phase in the presence of surfactants, or a water-in-oil emulsion obtained by emulsifying a aqueous phase in a fatty phase in the presence of surfactants.
- the emulsion is an oil-in-water emulsion.
- the fatty phase can contain at least one oil.
- oil means a compound which is liquid at ambient temperature (25 ° C.), and which, when it is introduced in an amount of at least 1% by weight in water at 25 ° C. C, is not at all soluble in water, or soluble in an amount of less than 10% by weight, relative to the weight of oil introduced into the water.
- the fatty phase can represent a mass percentage ranging from 10% to 70%, by weight relative to the total weight of said emulsion.
- the liquid fatty phase advantageously comprises one or more non-volatile oils which provide an emollient effect on the skin.
- fatty esters such as cetearyl isononate, isotridecyl isononate, isostearyl isostearate, isopropyl isostearate, isopropyl myristate, isopropyl palmitate, butyl stearate , hexyl laurate, isononyl isononate, 2-ethyl-hexyl palmitate, 2-hexyldecyl laurate, 2-octyl decyl palmitate, 2-octyldodecyl myristate or lactate, succinate 2-diethyl hexyl, diisostearyl malate, tracetin, tricprine, caprylic / capric acid triglycerides, triheptanoin, mixture of coconut caprate and caprylate,
- oils can also be oils of the hydrocarbon type, for example C15-C19 alkanes, or silicone oils such as paraffin oil, squalane oil, petrolatum, dimethylsiloxanes and their mixtures.
- the non-novatile oil is chosen from coco-caprylate / caprate, triheptanoin, diheptyl succinate / capryloyl glycerin / Sebacic acid copolymer, C15-C19 alkanes, or mixtures thereof
- the at least one non-volatile oil can be present in the emulsion in a percentage ranging from 10% to 70%, by weight relative to the total weight of said emulsion.
- the liquid fatty phase can also comprise volatile oils.
- volatile oil is meant an oil capable of evaporating from the skin, in less than one hour at room temperature and atmospheric pressure.

- the panel is made up of 18 people aged 20 to 23.
- the "EBItouch®” kit includes reference products, called “terminal”, for each sensory evaluation criterion, called “descriptor”. For each of these descriptors, the kit includes a terminal “0”, which corresponds to the minimum sensation of the descriptor, and a terminal “10” which corresponds to the maximum sensation of the descriptor.
- Each panelist applies the products to be evaluated (at least two) on the anterior face of his forearm, by spreading approximately 0.02 grams of each product on a disc of diameter approximately equal to 5 cm. All the descriptors are evaluated at the same time, during the following six stages: appearance of the product, setting of the product, application of the product, immediately after application of the product, one minute after application, two minutes after application.
- the evaluations of the panelists are processed statistically in order to establish, for each descriptor, an average, which is the “score” of the descriptor, and a standard deviation, and the value of the parameter “p”.
- the oil-in-water or water-in-oil emulsion has the texture of a whipped cream.
- the term “sensory agent with cushioning and soft effect” is understood to mean a functional ingredient capable of imparting to an emulsion, of the oil-in-water or water type. -in- oil, a sensory profile exhibiting a “cushion effect” descriptor and a “soft” descriptor, preferably having scores greater than or equal to 7 according to the evaluation by a sensory panel with the “EBItouch®” kit.
- Example 1 preparation of an oil-in-water emulsion of the "whipped cream” type
- An oil-in-water emulsion of the “whipped cream” type is prepared according to the composition of Table 1, following the protocol below.
- the sensory agent with a cushioning and soft effect is Glycolys® from Roquette Fromme. It is a carboxymethylated starch.
- phase A1 The ingredients of phase A1 are mixed and heated to 80 ° C. with gentle stirring with a deflocculating paddle at 250-500 rpm.
- Phase A2 is dispersed in phase A1 with stirring with a deflocculating paddle at 500-1000 rpm, maintaining a temperature of 80 ° C. and stirring for 40 minutes.
- phase B is prepared by mixing the ingredients and heating to 80 ° C.
- phase B is emulsified in phase A1 + A2 with stirring with a deflocculating paddle at 2000-3000 rpm for 10 minutes. Then allowed to cool naturally to 20-25 ° C with stirring at 500-1000 rpm. Phase C is added with stirring 500-1000 rpm at 20-25 ° C, then maintained for 5-10 minutes. Optionally, one finishes by adding phase D and E with stirring at 500-1000 rpm.
- an oil-in-water emulsion is prepared according to the composition of Table 1 without the Glycolys® from Roquette.
- a cream is obtained, with which the cream according to the invention is compared.
- Example 2 evaluation of the sensory profile by a panel
- the first three descriptors evaluated are visual characteristics of the product.
- the product is examined in the jar, under a lamp equipped with a 5500 K temperature bulb.
- the “opaque” descriptor of a product is defined by whether or not the product allows light to pass through.
- the “whiteness” descriptor is defined by the reference color palette of the "EBItouch®” kit. The product is compared to the color palette by a panel of reviewers.
- gloss is defined by the fact that the product reflects light or not.
- the following descriptors are evaluated when the product is used.
- the examination of 50 to 100 pL of the studied product is made between the thumb and the index finger, under the lamp.
- the "fluid" descriptor is evaluated when pressure is exerted on the product, between the thumb and forefinger. If it has no hold, flows from the fingers and moves away from the pressure zone, it is fluid, conversely it is non-fluid.
- the "cushion effect” descriptor is evaluated by exerting two light pressures of the product between the thumb and forefinger. When we feel a rebound or cushioning or cushion under the fingers, then we speak of the cushion effect. The amplitude of the rebound or damping is evaluated by a score out of 10: 0 corresponds to the "fluid terminal" reference of the EBItouch® kit, 10 corresponds to the "repairing hand cream for damaged hands, with allantoin" from "Mixa”.
- the "string” descriptor is evaluated by placing the product between the thumb and forefinger and slowly spreading the 2 fingers apart, a continuous thread forms between the 2 fingers. The thread breaks for an important separation of the fingers.
- the "slippery" descriptor is evaluated by placing the product between the thumb and forefinger and performing a rubbing motion (such as "finger snapping"), there is no resistance.
- the product facilitates the movement of the 2 fingers.
- the "soft" descriptor is evaluated during the application, from the 2 nd to the 5 th rotation. When we have a feeling sagging or thickness, we speak of softness.
- the amplitude of the softness is evaluated by a score out of 10: 0 corresponds to the “Fluid” limit of the EBItouch® kit, 10 corresponds to the “Non-opaque” limit of the EBItouch® kit.
- the "whitening" descriptor is evaluated during application, from the 2 nd to the 5 th rotation: the product whitens the skin.
- the "powdered” descriptor is evaluated between the 2nd and the 5th rotation.
- the fingers glide well on the skin.
- the product is perceived as a powdery substance on the skin.
- the amplitude of the powder is evaluated with a score out of 10: 0 corresponds to the "Slippery” limit of the EBItouch® kit, 10 corresponds to "The POREfessionnal: Pearl Primer" foundation from “Benefit”
- the examination is done under the lamp, on the skin, 1 minute after spreading 50 to 100mI of the product.
- the descriptor "soft" smooth in English is evaluated by performing a glide on the skin, a dry and slippery touch is felt.
- the "fat" descriptor is evaluated by pinching the skin between the thumb and forefinger: the thickness of the product between the fingers is evaluated.
- the criteria for improved sensory properties in the emulsion according to the invention are: the cushion effect, the softness, the powdery, the soft.
- Table 2 shows the sensory profiles evaluated for an oil-in-water emulsion without starch according to the invention, and for an oil-in-water emulsion. water with a starch according to the invention (Glycolys®), as prepared in Example 1.
- the sensory panel made it possible to demonstrate that the crosslinked carboxyalkylated starch Glycolys® makes it possible to obtain an oil-in-water emulsion exhibiting a cushion effect, a softness, a powdery and a soft touch.
