Description

[Cross-reference of related applications]
This application is entitled "Natural Hydrocarbon / Ester Compositions With Improved Sensory Properties, Formulations and Related Methods", March 1, 2018. Allegedly benefit from US Provisional Patent Application No. 62 / 637,129 filed under U.S.C. 119 (e), the disclosure of which is hereby incorporated by reference in its entirety. Form part of.

  Personal care and cosmetic products attract consumers not only due to aesthetic and hygiene concerns, but also as a means of social integration and health. However, among all the properties of such products, consumers rely mainly on their sensory aspects to decide whether to purchase the same product again. Most personal care and cosmetic carriers are both aqueous and oil phase compositions that are stabilized according to the rules of emulsion technology, but are based on formulations that are all oil-based, alcohol-based, or other solvents. Based formulations or aqueous-based formulations also exist as options.

  If water or any other volatile material is present in a personal care product, for example applied to the skin, those materials will volatilize after application due to normal body temperature. Non-volatile components such as emollient oil remain behind. Emollient oil conditions the skin, hair, or nails. Conditioning means refatting, lubricating, softening and smoothing, and / or reducing the appearance of fine lines and wrinkles.

  Many emollient oils are effective in conditioning the skin, but many can leave discomfort, greasiness or unwanted shine after use. There is often a desire for effective conditioning without the aforementioned negative properties, and there is a strong consumer desire for effective conditioning on platforms that provide a after-feel that is described as "light".

  One aspect that strongly influences the achievement of "lightness" is the thickness of the residual oil layer remaining on the treated surface, in addition to the properties of the oils themselves. The property of "easiness of application" refers to the ability of a substance of a liquid to spread over a particular substrate surface, ie the speed at which the liquid moves from the application area to the peripheral area and the distance from the application area. For example, in the case of skin application, the ease of application of a material affects its residual thickness and is related to the user's perception of "lightness". Materials that are easier to apply combine with larger areas of application, leaving a thinner coating.

  The ease of application is related to the viscosity, the affinity of the liquid for the substrate (adhesiveness), and the affinity of the liquid for itself (adhesiveness). For this reason, low viscosity liquids may spread more slowly than higher viscosity liquids. As an example, water, a highly polar and very low viscosity liquid, does not spread at all on the non-polar surface material Teflon ™ (polytetrafluoroethylene). Water has a high affinity for itself, and no affinity for Teflon ™.

  Fatty acid ester oils (“esters”) are used as emollients and conditioning agents and are included in the composition for use on keratinized surfaces such as skin, hair, and nails. The ester bond in the ester material is polar. Also, keratinized surfaces such as skin, hair, and nails are polar. Therefore, the ester is adhesive to these substrates.

  Esters adhere by polar-polar interactions and for that reason provide conditioning benefits, especially to the skin. This polar-polar interaction also causes the ester molecules to adhere to themselves and become tacky, reducing ease of application.

  Traditional personal care products have relied on petrochemical-derived esters delivered to these skins or "silicone fluids" / hair / nails in volatile carriers or solvents such as silicone oils or fluids. Volatile silicone oils such as cyclomethicone and low molecular weight dimethicone are essentially non-polar and therefore poorly adherent and tacky. Silicone oils have a low contact angle for hair and skin, which is associated with faster application and are volatile, ie they evaporate from the surface at room temperature. Due to their volatility, silicone oils do not remain on the substrate and therefore do not function as emollients or conditioning agents. However, silicone oils are useful for delivering non-volatile emollients, active ingredients, and other ingredients such as higher viscosity esters to substrates in applications such as antiperspirants. When mixed with other ingredients such as emollients and polymers, silicone oils increase the overall ease of application on the material, leaving a thinner residual layer on the skin surface, giving a desirable, lighter skin feel. However, silicone oils are also derived from petrochemicals.

  The trend away from the use of petrochemical-derived ingredients in personal care and home care remains strong. Products derived from renewable sources such as vegetable / plant materials may be presented to consumers as "natural" as opposed to petrochemical derived materials. In addition, many manufacturers have taken into account concerns related to deforestation, microclimate change and habitat destruction of native species, for example, the African oil palms Elaeis oleifera and Elaeis guineasis. guineessis) and / or maripa palm, and prefers to avoid "palm oil" -derived raw materials derived from oil palm or Attalea plants such as Attalea maripa.

  To date, several 100% plant-derived low-viscosity esters have been developed, including LexFeel Natural (heptyl undecylenate, INOLEX, Inc., USA), SustOleo DCS (diisooctyl succinate, INOLEX, Inc., USA), and SustOleo MCT (triheptanoin). , USA INOLEX, Inc.) etc. have been commercialized. Moreover, each of these products is not derived from palm oil.

  Hydrocarbon fluids are also known for use as carrier fluids and solvents. Many are volatile and, like volatile silicones, are non-polar, giving rise to low contact angles associated with faster coating on the substrate. For example, the Parafol (Sasol, Germany) series of linear hydrocarbons is derived from both coconut and oil palm sources. Another example is Neossence Hemisqualane (Amyris, USA), a hydrogenated farnesene of a branched chain hydrocarbon material containing a total of 15 carbon atoms.

  The parent material, farnesene, is derived from fermentation of sugar cane, for example, as described in WO2201759136, the contents of which are incorporated herein by reference.

  The use of ester oils admixed with hydrocarbons is disclosed. For example, Patent Document 1 describes a mixture of an ester derived from neopentyl glycol and isododecane for reproducing the tactile sensation of a cyclomethicone solution, and these mixtures are derived from materials originating from petrochemicals. Therefore, it cannot be labeled as natural.

  Patent Document 2 discloses a mixture of a coconut-derived straight-chain hydrocarbon and a non-volatile oil which is said to mimic the feel of silicone. The branches in the alkane structure provide a lighter texture because they cannot pack as closely as a linear alkane.

Example 1-Preparation and Analysis of Compositions of the Present Invention Ten types of compositions containing the raw materials shown in Table 1 below were prepared.

  All components are liquids at room temperature. Prepared by adding each of the above samples to a suitable container and stirring until uniform.

  Each sample was evaluated for the following properties using the analytical techniques shown in Table 2.

  The content of each ASTM is incorporated herein by reference.

  The evaluation results are shown in FIG.

Example 2-Evaluation of Average Expansion Rate as a Criteria for Ease of Application The expansion rate of each of Sample Composition 1-Sample Composition 10 was evaluated using the following basic procedure. An artificial skin substrate was used to determine the average rate of expansion. Expansion is the rate at which the expansion area increases. Expansion is always fastest at the moment the liquid contacts the substrate and then asymptotically slows to zero over time.

  To determine these values, a 3 inch by 3 inch square VITRO-SKIN ™ (IMS, Inc., Portland, Maine, USA) membrane strip was used at room temperature (23 ° C.) and 60% humidity for 16 hours. It was prehydrated in a humidity chamber set to. A micropipette was filled with the test material and placed exactly 1 inch above the artificial membrane using a ring stand. The experimental apparatus is shown in FIG.

  A drop of the sample composition (50 μL) was dropped on the center of a 3 inch by 3 inch square VITRO-SKIN ™. The expansion went outward from the point of contact, creating a circular spot. Since the wet circular area of VITRO-SKIN ™ can be seen, the diameter can be measured. The expanding diameter was measured at 1, 3, and 5 minutes after contact. The diameter of the spot was taken in centimeters, and the radius was obtained by dividing the spot into two parts. The radius was squared, and then the product was multiplied by π to specify the expanded area. The data obtained gives the areas at 1 minute, 3 minutes and 5 minutes. The additional area covered can be calculated by subtracting the area at each time point from the area at the previous time point. Thus, the average rate of expansion can be determined by dividing the covered area by the time interval for each interval, then by the total number of time intervals. Therefore, the equation for determining the average expansion rate for three intervals per experiment is:

SAt1 = [(D1 cm / 2) ² π The unit is cm ² . t1 = 1 minute-0 minutes = 1 minute.
SAt2 = [(D2cm / 2) ² π The unit is cm ² . t2 = 3 minutes-1 minute = 2 minutes.
SAt3 = [(D3 cm / 2) ² π The unit is cm ² . t3 = 5 minutes-3 minutes = 2 minutes.
In the formula,
D1 = diameter of circle after 1 minute D2 = diameter of circle after 3 minutes D3 = diameter of circle after 5 minutes SAt1 = area of circle after 1 minute SAt2 = area of circle after 3 minutes SAt3 = after 5 minutes Area of circle

Therefore,
Average Expansion rate ^{= [(SA1-0) cm 2/} 1 min ^{+ (SA2-SA1) cm 2} /2 min ^{+ (SA3-SA2) cm 2} /2] / 3

  The average expansion rate was determined for each sample number. The results are shown in Fig. 4. Results are the average of 3 measurements.

Example 3-Sensory Analysis by Panelists Sensory analysis of personal care and cosmetic products to assess and compare the properties of each product at all stages of human use relies on panelists' perception. In this example, panelists focused on explaining the tactile (post-use) perception of the product on the skin after picking, spreading, and applying.

  During the hand-picking phase, panelists evaluated the "stickiness", which is the strength with which the finger adheres to the skin, and tested using the index and thumb tips.

  During the spreading stage, panelists determined the "spreadability", which is the spreadability of the product on the skin, and tested by applying the product to the forearm with the opposite hand.

  Finally, in the post-use feeling stage, panelists were instructed to consider skin slipperiness, residue and gloss. "Skin slip" is the ease of moving two fingers on the skin of the forearm after spreading the above product. "Skin rest" is a perception of the amount of product left on the skin perceived with the fingertips after spreading the product. “Glossy” is the amount or degree to which the skin reflects light under the same lighting settings.

  Before testing the sample composition, all panelists should understand the meaning of each technical term and how each aspect of this sensory analysis (handling, spreading, and after-use feeling) should be determined. Trained in advance. Prior to evaluating the test formulations, the panel was calibrated by testing a standard reference sample for each of five low and high level parameters (greasiness, ease of application, skin slip, skin remnant, and gloss).

  Even though the panelists perceived different intensities for each reference, they all agreed on which sample exhibited lower and higher levels of each parameter. The procedure used in this sensory panel was based on that recommended by the American Society for Testing Materials (ASTM E1958, the contents of which are incorporated herein by reference).

Example 4-Formulation of Antiperspirant Sticks Comprising the Compositions of the Invention Whitening of skin or clothing is undesirable in antiperspirant sticks containing solid antiperspirant actives such as aluminum salts. Common aluminum salts used in antiperspirant applications are chlorohydroxyaluminum (ACH), activated chlorohydroxyaluminum (AACH), conventional aluminum zirconium actives (ZAG actives), and activated aluminum zirconium actives. (AZAG). A typical antiperspirant stick may include a waxy substance, a film-forming substance, a fragrance, and a volatile carrier fluid. The following example shows how the composition of the present invention can reduce whitening.

  An exemplary antiperspirant stick was prepared according to the following composition. A common silicone material, cyclomethicone, was a comparative prior art fluid.

  The above formulation was made by mixing the ingredients of Phase A in a beaker. In a separate beaker, the Phase B ingredients were blended together using a Speed Mixer. Then, Phase B was added to Phase A, stirred with a magnetic stirrer, then heated to 80 ° C. and maintained for 10 to 30 minutes. After cooling the mixture to 70 ° C., Phase C was added. The mixture was cooled to 65 ° C., poured into a canister and then cooled to room temperature. What was obtained in each case was a solid stick.

  The stick was rubbed onto black paper to illustrate the reduction in bleaching. Pictures were taken at time zero (first), after about 30 minutes, and after 1 hour. Figures 5, 6 and 7 show Formulation A containing the composition of the present invention at three time points, Control formulation Formulation B, and two commercial antiperspirants of Cincinnati, Ohio, USA. "Secret Australia Eucalyptus Blossoms" manufactured by Procter & Gamble and Dove Powder Invisible Solid manufactured by Unilever (Port Sunlight, UK) are shown.

  The photographs of FIGS. 5, 6 and 7 show a dramatic reduction in bleaching by including the composition of the invention of Example 6, Sample # 6.

Example 5-Formation of Eye Shadows Containing Compositions of the Present Invention Desirable properties in color cosmetics such as eye shadow pots are: ease of handling, improved color payoff, feeling of richness, and use. A moisturizing feeling afterwards can be mentioned. Color payoff refers to the amount of color depth and amount of vibrance observed when equal amounts of product are applied. That is, if the same amount of product A as product B is applied to the skin, product B is said to be better if product B exhibits a higher depth of color. A more pleasant, silky, smooth after-feel is a desirable property.

  The following formulations were prepared as examples of prior art and inventive eyeshadows for comparison. A common silicone material, cyclomethicone, was a comparative prior art fluid. Formulation EA comprises the composition of the invention, but not EB.

  To prepare the above formulation, the ingredients of Phase A were combined in a beaker using a high speed mixer with a stirring speed of 3500 rpm. Then the ingredients of phase B were added, the mixture was heated to 80 ° C. and stirred using a magnetic stirrer. Once the mixture was smooth and homogeneous, it was cooled, then poured into a container and cooled to room temperature.

  To illustrate color payoff, equal amounts of each formulation were rubbed on black paper. 8 and 9 show photographs showing the improvement of color payoff on black paper and human skin.

Example 6-Preparation of Cationic Lotion To illustrate the improved organoleptic properties that can be obtained using the fluids of the present invention as compared to the very common prior art fluid cyclopentasiloxane. The following cationic lotions were prepared.

  The above formulation was prepared by combining the ingredients of Phase A in a beaker and heating with propeller agitation to about 80 ° C. until homogeneous. The ingredients of Phase B were combined in separate beakers and heated to about 80 ° C. by propeller agitation. Phase B was then added to Phase A and homogenized for about 3 minutes at 4000 RPM.

  After that, homogenization was stopped, stirring was replaced by propeller mixing, and the mixture was cooled to about 50 ° C., forming an emulsion. The emulsion was poured into a canister and cooled to room temperature. The resulting viscosities were 58500 centipoise for CA and 39000 centipoise for CB. The resulting pH was 4.16 for CA and 4.06 for CB.

  The organoleptic properties of the emulsion were panels evaluated as described previously. The results are shown in the diagram of FIG.

  It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the broad inventive concept. Therefore, it is understood that the invention is not limited to the particular embodiments disclosed, but is intended to include modifications within the spirit and scope of the invention as defined by the appended claims. To be done.
