I.Suitable emulsion-O/W (Oil in water emulsion)
As a widely used formula system in the current skin care product market,
Oil in water emulsifier has become the first choice for oily skin, mixed oily skin and even people who pursue a light skin care experience due to its refreshing, easy-to-absorb and light skin feeling. Cetearyl olivate or sorbitan olivate, a liquid crystal
Emulsifier of natural origin, is the high-quality suitable raw material for this system. With its excellent emulsifying ability, stable physical and chemical properties, and natural ingredient properties, it provides a new possibility for the research and development and production of oil-in-water skin care products such as lotions, creams, and sun protection products.
This emulsifier is a compound of two nonionic surfactants derived from olive oil. Its fat-soluble properties make it extremely adaptable in the oil-phase deployment of oil-in-water systems, and it can quickly blend with various oil-phase raw materials without complex process operations. Efficient emulsification can be achieved, which is also a highlight that distinguishes it from ordinary emulsified raw materials.And its core emulsifying advantages are mainly concentrated in three aspects：
1. The emulsifying efficiency is outstanding and the formula has strong stability. It can efficiently blend the oil phase and the aqueous phase components evenly, making the formula structure of the emulsion more stable, and effectively avoiding the problems of stratification, agglomeration, and uneven texture of the product during production, storage, and use. Even if a variety of active ingredients are added, the effective oil-in-water emulsion can always maintain a delicate and uniform texture under its action, greatly improving the overall quality of the product.
2. It can form a unique liquid crystal structure. This structure is similar to the structure of the stratum corneum of human skin. It can not only further strengthen the emulsifying effect, so that the oil phase and water phase of the oil in water emulsion are more closely combined, but also assist in enhancing the skin barrier function, so that the oil in water emulsion maintains a refreshing skin feeling. On the basis of superimposing moisturizing and repairing skin care effects, realize the dual effects of emulsification and skin care.
3. The formula has strong compatibility and can be harmoniously matched with various raw materials commonly used in skin care product research and development. There will be no conflict of ingredients. For example, when used with
Emollients such as
C12 15 alkyl benzoate, it can neutralize its slight greasy feeling and further enhance the freshness of the oil-in-water emulsion. When used in combination with
MYRISTYL MYRISTATE, it can also enhance the silky touch of the emulsion, and its recommended addition amount is 1-5%, and a small amount of addition can produce a good emulsifying effect.
At the same time, VEGEFIERS™ MY CSO 99 (cetearyl olivate or sorbitan olivate) has stable physical and chemical properties. It is yellowish granular at 25℃. Its acid value is lower than the standard limit. The content is up to standard and stable. In large-scale production, it can provide a stable raw material guarantee for oil in water emulsions and will not affect product quality due to fluctuations in raw material performance.Moreover, its ease of operation is also high, and the deployment can be completed in the conventional skin care product production process without additional production equipment or processes, taking into account the production efficiency and product quality.
In addition to basic moisturizing lotions, it can also be widely used in various oil-in-water skin care products such as refreshing creams, sunscreen lotions, and makeup creams. The application scenarios are very rich.In sunscreen emulsions, its emulsifying stability allows the sunscreen ingredients to be evenly dispersed in the aqueous phase system, avoiding the problem of uneven sunscreen effect and local whitening.In products such as makeup cream that have both modification and skin care effects, it can make the texture of the product lighter and more obedient, reduce the phenomenon of stuck powder and rubbing mud, and further expand the research and development boundaries of skin care products in the oil in water system, and provide formulators with more research and development ideas.
As an emulsified raw material of natural origin, it has more advantages in gentleness than synthetic emulsifiers. Under normal use concentration, it is less irritating to the skin and is suitable for most skin types.
II.Advantages of skin sensation regulation
The core competitiveness of Cetearyl olivate or Sorbitan olivate is its powerful skin sensation regulation function, which can be tailored for oil in water lotion to create a light, silky, refreshing and non-sticky feeling.
The skin sensation regulation of this raw material is not a single-dimensional optimization, but covers the whole process of skin care such as application, absorption, and follow-up skin sensation. From the moment it touches the skin, it can bring a different feeling of use, which is specifically reflected in three aspects.：
1. The application stage is smooth to the touch. It is not sticky and does not rub mud when pushed away. It can quickly spread on the surface of the skin. There will be no “can't be pushed or wiped evenly”. Even people with dry skin can use it in a state of dry skin. It can be easily applied, and there will be no problems of stuck lines and agglomeration due to lack of water on the skin.
2. The penetration speed is faster in the absorption stage. Its unique liquid crystal structure can assist in promoting the penetration and absorption of active ingredients in the emulsion, so that skin care ingredients can enter the surface of the skin faster, avoiding the common “floating on the surface” problem of oil-in-water emulsions, so that consumers can truly feel the absorption effect of skin care products.
In the actual formulation application, its skin sensation regulation ability can also be flexibly adjusted according to the positioning of the product to meet the needs of different skin types and different use scenarios.
1.For the basic moisturizing oil in water lotion, which focuses on clear and moisturizing, it can further strengthen the freshness of the product and make the skin feel lighter. It is suitable for oily skin and mixed oily skin to be used in summer or in a sultry environment.
2.For the oil in water lotion, which focuses on moisturizing and repairing, it can ensure freshness while enhancing the silky smoothness and moisturizing feeling of the lotion, so that dry and mixed dry skin can get enough moisturizing and repairing when used in spring and autumn or dry winter without feeling greasy.
3.For the main portable travel oil in water lotion, it can make the skin feel of the product more suitable for outdoor use scenarios, absorb quickly, not sticky, and avoid skin care products due to sweating, makeup loss, and stuffy skin problems.
Moreover, its skin sensation regulation function can also form a synergistic effect with various skin care product raw materials, so that the skin sensation and efficacy of the lotion can be double improved.For example, in the oil in water emulsion with
Ammonium acrylate copolymer added, this emulsified raw material can work with this ingredient to enhance the film-forming properties of the emulsion, making the film thinner and more skin-friendly, and further optimizing the skin feeling performance.When combined with moisturizing ingredients such as
Peg 7 glyceryl cocoate, it can make the moisturizing effect longer-lasting and keep the skin feeling fresh at all times.
It is worth mentioning that this raw material is a 1:1 alternative to imported similar liquid crystal emulsified raw materials, which has important practical value for domestic cosmetics manufacturers.Previously, many companies chose imported natural liquid crystal emulsifiers when developing high-end oil-in-water emulsions. Although the effect is excellent, the cost of raw materials is high, and it is affected by factors such as international logistics and raw material supply. There are certain supply risks, and this domestic emulsified raw material is comparable to imported raw materials in terms of performance, skin feeling, and stability.
At the same time, the characteristics of its natural sources make the products more in line with the market trend of “natural skin care”, which provides a boost for companies to create differentiated products and attract more consumers who pay attention to natural and gentle skin care.From the perspective of industry development, natural, efficient, and emulsified raw materials with skin sensation regulation capabilities are becoming the mainstream development direction of the cosmetic raw material market. cetearyl olivate or sorbitan olivate integrates the efficient adaptation of the oil in water system with multi-dimensional skin sensation regulation, which not only provides new raw material options for the research and development and upgrading of oil in water emulsions, but also infuses new vitality into the innovation of raw materials in the cosmetics industry.
