Beta-Cyclodextrin (stabilizer, emulsifier)

Beta cyclodextrin Beta cyclodextrin (BCD) is a type of oligosaccharide that is formed with the participation of enzymes from starch.
Description: white crystalline powder, odorless, sweetish taste, soluble in water, practically insoluble in methanol, ethanol, propanol and ethyl alcohol.
pH: 6.0.
Main substance content: 99.89%.

Functions of Beta-cyclodextrin (according to the International Cyclodextrin Association):

-protection of materials from oxidation and aging under the influence of UV during storage or use;

- stabilization of flavors and spices;

- masking bitterness and unpleasant odors of food products and medicines;

-conversion of liquid materials into dry forms;

-improving the solubility of substances with low solubility in water;

-emulsification of hydrocarbons, steroids, fats and fatty acids;

- controlled action of active components of drugs and flavorings;

- catalyst for chemical reactions;

- artificial environment for chemical synthesis;

Mobile phase additive and stationary phase component for HPLC or TLC
Due to its unique characteristics, beta cyclodextrin is widely used
used in the pharmaceutical, food, cosmetics and agriculture industries.

The world's largest companies, such as Procter&Gamble, Ai-Star Co. and Revlon use Beta Cyclodextin in cosmetics.

List of functions that Beta-cyclodextrin can perform in cosmetics
drugs:
- barrier against free radicals;
- anti-inflammatory component;
- soothing component;
- antioxidant;
- corrosion inhibitor;
- deodorant;
- emulsifier;
- agent for encapsulation and micro-encapsulation;
- moisturizing and wetting component;
- dye fixer;
- powder additive;
- preservative;
- thickener;
- conditioning agent;
- stabilizer.

Recommended minimum dosage - 0.1% maximum - 10%.

The ratio with active components is equal parts (1:1).

Beta-cyclodextrin does not have an irritating effect and at the same time acts as a stabilizer of active components, reduces the volatility of active molecules, and masks unpleasant taste and odor. It can be used in cosmetic milk, paste and liquid forms. Beta-cyclodextrin increases the stability of fragrances and cosmetic fragrances.
Beta-cyclodextrin combined with vitamin C
Higher ester fractions and higher aliphatic esters of vitamin C can dissolve in water, but there are known difficulties with fat solubility. At the same time, vitamin C is used as a whitening component, but under the influence of light, heat, oxygen and alkali it can acquire a yellow and even brown tint. If vitamin C is administered in combination with Beta-cyclodextrin, the above-described disadvantages will be eliminated. Cyclodextrin makes ascorbic acid more stable and promotes its penetration into the dermis layer without causing irritation to the epidermis. Vitamin C with the addition of Beta-cyclodextrin can be used in liquid cosmetic milk, lotions, creams, and children's cosmetics. The finished product will be stable in color and odor when exposed to heat, light and air.

Anti-inflammatory and soothing effect Beta-cyclodextrin
Cyclodextrin has the ability to block provoking fatty acids
inflammatory processes that are accompanied by acne.

The input percentage depends on the final product and its purpose:
- to give a pearly shine to hair products - 2.5-5%;
- cosmetics for absorbing excess oil (mattifying creams and shampoos for oily hair) – 0.5-5%;
- creams, serums - 5-8%;
- anti-acne products – 2-5%;
- deodorants (deodorants can be watery or anhydrous.) – 0.1-10%;
- cleansing acne-prone skin - 2-3%;
- in anti-acne products - 1-5%.-

The component is introduced into the aqueous or active phase. Pre-dissolve in hot (at least 50?С) water. Before mixing the components, the Beta-Cyclodextrin solution is cooled.

Beta-cyclodextrin can be added directly to the cream to absorb unpleasant odor from the oil. But keep in mind that it eliminates all odors, including fragrances and any other odors.
